GENERAL INFORMATION

Air Conditioning System

The Bard air conditioning system is composed of MULTI-TEC wall-mounted air conditioners matched with an LC6000 supervisory controller or Bard PGD stand-alone display. If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 supervisory controller or a PGD stand-alone display. If more than one wall-mount unit is installed, the LC6000 controller must be matched with the air conditioning units. The wall mounts are specifically engineered for telecom/motor control center rooms.

NOTE:

The LC6000 supervisory controller and MULTITEC wall-mount units are designed specifically to work together. The controller cannot run other brands of systems, nor can other controllers run the MULTI-TEC wall-mount units. They are a complete system, and must be used together.

Wall-Mount Air Conditioner Units
The MULTI-TEC units are designed to supply full rated cooling airflow in free cooling mode with ability to exhaust the same amount through the unit itself without any additional relief openings in the shelter. In the event that free cooling operation cannot satisfy the load requirements, mechanical cooling will be utilized to assist in cooling the shelter.
MULTI-TEC units are fully charged with refrigerant and have optional electric heat.

General
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.
The refrigerant system is completely assembled and charged. All internal wiring is complete.
The unit is designed for use with or without duct work. Flanges are provided for attaching the supply and return ducts.
These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.
These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly any tags and/or labels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See ADDITIONAL PUBLICATIONS for information on codes and standards.
Sizing of systems for proposed installation should be based on heat loss and heat gain calculations made according to methods of Air Conditioning Contractors of America (ACCA). The air duct should be installed in accordance with the Standards of the National Fire Protection Association for the Installation of Air Conditioning and Ventilating Systems of Other Than Residence Type, NFPA No. 90A, and Residence Type Warm Air Heating and Air Conditioning Systems, NFPA No. 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.
Shipping Damage
Upon receipt of equipment, the cartons should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier's agent.
These units must remain in upright position at all times.
Additional Publications
These publications can help when installing the air conditioner. They can usually be found at the local library or purchased directly from the publisher. Be sure to consult the current edition of each standard.

TEC-EYE Hand-Held Service Tool
The TEC-EYE service tool is used to communicate with the MULTI-TEC unit logic board. By connecting directly to the logic board inside the unit control panel, it is possible to perform diagnostics on the unit, adjust certain settings and verify unit and economizer operation through a self test procedure. The TEC-EYE service tool is required for unit setup and operation. The TEC-EYE is supplied with the LC6000 controller but can also be ordered separately (Bard P/N 8301-059).
The menu driven interface provides users the ability to scroll through two menu levels: Quick Menu and Main Menu. The menus permit the user to easily view, control and configure the unit.
The controller is completely programmed at the factory; the default setpoints and their ranges are easily viewed and adjusted from the TEC-EYE display. The program and operating parameters are permanently stored on FLASH-MEMORY in case of power failure.
The TEC-EYE connects to the wall-mount unit control board via an RJ11 modular connector as shown in Figure 3.
When not being used, the TEC-EYE hand-held diagnostic tool should be stored inside or near the LC6000 controller. Do not let the TEC-EYE leave the shelter.

Software Name: The name of the software is the base part number used to identify which product the software is used in.

Model/Serial Number Retain
Model numbers and serial numbers will be retained through most software updates. It still remains good practice to verify the software version, model numbers and serial numbers of any wall-mount unit after a software update, as some functionality of the MULTITEC wall-mount unit require a specific model number.
Model Number Verification
The MULTI-TEC software will check the entered model number against available unit sizes/configurations. If there is an issue with model configuration, the unit will display Invalid Model # as the Unit Status and an alarm will turn off the unit to prevent damage to the unit.
Time/Date/Timezone Sync
On MULTI-TEC wall-mount unit models with a software version number MTS1000.2.0.0 and higher, when the wall-mount unit is connected and correctly addressed to a LC6000 supervisory controller, local time, date, and timezone information will be synced from the LC6000. This feature allows for faster set-up and correct correlation between alarm logs.

Alarm Adjustment
Mixed Air Alarm The mixed air alarm is used to indicate proper operation of the economizer. An alarm will be generated when the mixed air temperature is above or below two independent setpoints. This alarm can be adjusted by changing the alarm setpoints and/or delay. The differential low references the economizer control setpoint. For example, if the economizer setpoint is 55°F (as shown in Figure 24 on page 17) and the differential is set to 10, the lower limit for the mixed air alarm would be 45°F. The high differential references the outdoor air temperature setpoint that enables the economizer. For example, if the outdoor air temperature setpoint for economizer enable is set to 65°F and the high alarm is set to 5, the alarm would actuate at 70°F. The alarm also has a delay to help reduce nuisance alarms. With the delay set to 120 seconds, either the high mixed air or low

Refrigerant Low Pressure When the low pressure switch indicates a low pressure condition and there is an active call for cooling, the controller will generate an alarm (after a delay). The delay used by the low pressure alarm is determined by the outdoor air temperature (OAT on display). If the outdoor air temperature is below 55°F, the delay is 180 seconds (LDel on display). If the outdoor temperature is above 55°F, the delay is 120 seconds (Del on display). The unit will also have an address-based delay that will affect start up time; the default is 5 seconds multiplied by unit address. (The unit address-based delay is only when the unit is in orphan mode operation.) Additionally, if the outdoor temperature sensor is not used, the delay is set to 180 seconds. The controller will try to run the refrigeration system two times before the alarm will lock the compressor out. If 15 minutes (Two Count Del value on display) passes before the second attempt, the number of tries will be reset. To adjust these values: 1. Press MENU key to go to the Main Menu screen. 2.

Refrigerant High Pressure
When the wall-mount unit receives a signal from the compressor control module (CCM) indicating a high pressure event, the wall-mount unit will generate an alarm. Upon receiving the alarm, the wall-mount unit will remove the "Y" call from the CCM, resetting the status of the CCM. The alarm will stay present on the wall-mount unit until manually cleared. This operation has no configurable parameters.
Economizer Damper
When the controller commands the economizer damper actuator to a position other than 0% and the damper switch indicates the damper is not open, after a delay of 120 seconds (Open Del on display) the controller will generate a damper failed to open alarm. When the controller commands the economizer damper actuator to the 0% position and the damper switch indicates the damper is not closed, after a delay of 300 seconds (Close Del on display) the controller will generate a damper failed to close alarm.

CONTROL OPERATION

NOTE: Screenshots shown in this manual reflect default settings (when applicable).
On/Off Control
The wall-mount unit can be turned on and off with the TEC-EYE. When the unit is set to ON, the system will heat and cool the space either in orphan mode or when connected to the LC. When the unit is set to OFF, the unit will not heat or cool the space.
To turn the unit on or off:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter USER password 2000.
3. Press UP or DOWN keys to scroll to ON/OFF; press ENTER key.
4. Press UP or DOWN key to change the system from OFF to ON or from ON to OFF.
5. Press ESCAPE key until Main Menu screen is displayed.
Blower Control
The blower will be in continuous operation in orphan mode. To operate the blower continuously while communicating with the LC6000 or PGD stand-alone display, refer to the latest version of the 2100-669 LC6000 Service Instructions manual or 2100-734 PGD manual.
The 11EER MULTI-TEC wall-mount unit is equipped with an ECM 5-speed blower. Three different speeds are used: Low for Balanced Climate, nominal for normal blower operation and high for high sensible (see Figure 19).
FIGURE 19 Blower Speeds

Blower Speed 2 Nominal (N08)
This blower speed is available when the unit is in cooling, heating, orphan mode, freeze condition, free cool or continuous blower.
Blower Speed 3 High Sensible (N09)
This blower speed is available when the unit is in high sensible mode, which is selectable from the LC6000 controller, and cooling mode is active.
The Balanced Climate (blower speed 1) and high sensible (blower speed 3) are only available when connected to the LC6000 controller.
IMPORTANT: If the unit model number does not have the letter B as the fifth character (Ex. W36ABP...), the blower will not run in orphan mode.
Balanced Climate Mode
MULTI-TEC Series wall-mount units offer an enhanced latent capacity that can be controlled by an LC6000 controller. When passive dehumidification (Balanced Climate mode) is active on the LC6000 controller, the unit will increase the amount of moisture removed during compressor operation. When high sensible mode is enabled on the LC6000 controller, this mode increases the sensible cooling capacity to increase the amount of heat removed from the structure during compressor operation.
Balanced Climate Enable/Disable
When the MULTI-TEC is connected to an LC6000 controller, Balanced Climate mode can be enabled or disabled. Balanced Climate mode is disabled by default.
To enable or disable Balanced Climate mode:
1. Press MENU key to access the Main Menu Screen.
2. Press UP or DOWN keys and ENTER key to enter USER password 2000.
3. Press UP or DOWN keys to scroll to Adv Sys Config; press ENTER key.

FIGURE 20 Balanced Climate Enable/Disable
Temperature Control
When the unit is connected to the LC controller, it will receive all of its heating, cooling and ventilation commands from the controller. When the unit is in orphan mode, it will heat, cool and ventilate based on the return air temperature measurement. The return air temperature will be compared to the cooling setpoint. Based on differentials above and below the setpoint, the available cooling and heating stages will be utilized. Cooling Sequence Economizer Available (see Figure 21) If the return air temperature is higher than 79°F (Setpoint + Stage 1 Diff On) and outdoor conditions are acceptable for economizing, the unit will enable the economizer. If the return air temperature is higher than

80°F (Setpoint + Stage 2 Diff On), the unit will enable mechanical cooling stage 1. If the control value is higher than 81°F (Setpoint + Stage 3 Diff On), the unit will enable mechanical cooling stage 2.
Cooling Sequence Economizer Not Available (see Figure 21)
If the return air temperature is higher than 79°F (Setpoint + Stage 1 Diff On), the unit will enable stage 1 mechanical cooling. If the return air temperature is higher than 80°F (Setpoint + Stage 2 Diff On), the unit will enable stage 2 mechanical cooling.

Free Cooling
If the unit is equipped with an economizer, and conditions are acceptable for economizer operation, the MULTI-TEC wall-mount unit will utilize free cooling operation before the use of any cooling operation requiring compressor operation to reduce the energy required to cool the indoor space.
Economizer Disable
There are two methods to disable the economizer if the use of free cooling is restricted. The first method is to select None as the economizer type within the Sys. Config. menu. The second method requires changing the model number within the Adv. Sys. Config. menu to reflect a model installed with a blank-off plate (see model nomenclature in Figure 1 on page 3). Changing the wall-mount unit model number to reflect a unit with a blank-off plate will not allow for an economizer type

6. Press UP or DOWN keys to adjust parameter value.
7. Press ENTER key to save.
Economizer Note
The economizer and mechanical cooling can operate simultaneously because the economizer uses the mixed air temperature sensor.
Emergency Cooling
When return air temperature rises above 95°F, the unit will enter emergency cooling mode and an alarm will be displayed (unit can also be commanded by LC6000 to enter emergency cooling mode). In emergency cooling mode, if the unit is equipped with an economizer (and the model does not indicate a blank off plate), the economizer operation will ignore current setpoints. If the return air temperature is above the outdoor air temperature, the economizer will open and the unit will enter optimized cooling. If at any point the return air temperature falls below the outdoor air temperature or the mixed air temperature falls below 65°F, the economizer will close. This is done in an effort to cool the space as quickly and efficiently as possible. This feature will be disabled by a model number indicating a blank off plate (model # position 10 set to `B') which disables all economizer function.
Unit Disable
The wall-mount unit can be disabled by opening a dry set of contacts connected to Input DI1 on the PLC board. This feature can be used in addition to the emergency off feature provided by the LC6000 to ensure that the unit does not operate even when in orphan mode. This feature is disabled by default and must be enabled before the input will affect unit operation. When the input detects open contacts, all unit operation will stop and the dampers will close. This is an automatic reset feature that will resume operation as soon as the unit detects the contacts are closed again.
For applications that require the dampers to close rapidly, an additional relay should be installed that either breaks the 24VAC power supply to each actuator or breaks the low voltage power supply to all units. In normal operation, the dampers can take up to 2 minutes to close from fully open. When the 24VAC power is removed from the actuator, the dampers will close in under 30 seconds using the spring return on the actuator.
NOTE: Alarm logging and trend logging will not be available if power is removed from the controller and unit offline alarms will be recorded on the LC6000.

Dehumidification
Dehumidification Modes
Dehumidification Off
When the humidity level inside a zone falls to the Dehumidification Off setpoint, the system will stop attempting to dehumidify the space. The default setpoint value for this mode is 60% RH.
Passive Dehumidification
When the humidity level rises to the Passive Dehumidification setpoint, the controller will activate staged dehumidification at the available wall units. As the humidity level rises to the passive dehumidification setpoint, the free cooling function (economizer) is disabled. When there is a call for cooling, the compressor will energize and the blower speed will be reduced to the unit dehumidification mode or Balanced Climate speed whichever is applicable to the unit. All units allowed to run within the zone will be given the dehumidification command and will operate as such on a call for cooling. The default setpoint value for passive dehumidification is 70% RH.
Active Dehumidification
When the humidity level rises to the Active Dehumidification setpoint, the supervisory controller will active staged dehumidification at the available wall units. The supervisory controller will then calculate the dehumidification demand based on how far above the setpoint and how long the RH level has been above the setpoint. The controller will then utilize all of the units with active dehumidification capabilities to reduce the indoor humidity level. The units will be staged on based on the existing cooling rotation for the units in the zone up to the maximum number of units allowed to run. When in demand minimum compressor run time is applicable, examples of demand are as follows:
With two units with dehumidification capabilities, Unit 1 in rotation will come on at 50% demand and Unit 2 in rotation will come on at 100% demand. They will rotate off in a reverse; Unit 2 will be off at 50% demand and Unit 1 will be off at the dehumidification off setpoint.
With three units with dehumidification capabilities, Unit 1 in rotation will come on at 33% demand, Unit 2 in rotation will come on at 67% demand and Unit 3 in rotation will come on at 100% demand. They will rotate off in reverse; Unit 3 will be off at 67% demand, Unit 2 will be off at 33% demand and Unit 1 will be off at dehumidification off setpoint.
An active dehumidification sequence will run until the space temperature falls to the heating setpoint or increases to the cooling setpoint, or the dehumidification off setpoint is reached. Refer to the specific unit manual for active dehumidification sequence and space temperature control.

The passive dehumidification setpoint must be lower than the active dehumidification setpoint to ensure the economizer is disabled during active dehumidification.
Availability for active dehumidification will be determined by model number. Units with electric reheat, mechanical dehumidification or cycling reheat will be considered. The active dehumidification default setpoint is 80% RH.
Electric Reheat Dehumidification
Electric reheat dehumidification is only available as a factory-installed option that must be ordered with the unit. It cannot be installed in the field on an existing unit.
Dehumidification will only become active if the unit is connected to the LC6000 and the appropriate conditions are present.
Electric Reheat Dehumidification Operation
When the wall-mount unit receives a dehumidification call from the LC6000, the wall-mount unit will disable the economizer to force the system to use air conditioning and prevent any additional humidity from being introduced from outdoor air. The wall-mount unit will then turn on the air conditioning system which will remove moisture and cool the space. At the same time, the electric reheat coil will be energized to extend the run time of the cooling cycle and prevent cool air from being introduced to the space.
On a call for electric reheat dehumidification, the unit return air sensor will control the compressor and heating element operation based on the supervisory control setpoints. If the space temperature, based on the sensor attached to the supervisory control, reaches the cooling or heating setpoint, the dehumidification call is overridden until the cooling or heating call is satisfied. If communication is lost with the supervisory controller during a dehumidification call, the electric reheat function at the unit is lost and the unit will operate in orphan mode.
During a call for electric reheat, the wall unit will energize the compressor and the electric reheat coil will be energized to extend the run time of the cooling cycle, mitigating the cooling done by the compressor. If/when the temperature falls to 2° above heating setpoint, the compressor will be disabled until the temperature is increased 2° below the cooling setpoint and then the compressor will be re-energized (see Figure 29 on page 20). If/when the temperature reaches 4° below the cooling setpoint, the electric heating elements will be energized. The electric heating elements will be disabled 2° below the cooling setpoint. The system will continue the dehumidification process until either the heating or cooling setpoint are reached again or the requirement for dehumidification is no longer present.

GENERAL REFRIGERANT INFORMATION

These units require R-410A refrigerant and polyol ester oil.
General
1. Use separate service equipment to avoid cross contamination of oil and refrigerants.
2. Use recovery equipment rated for R-410A refrigerant.
3. Use manifold gauges rated for R-410A (800 psi/250 psi low).
4. R-410A is a binary blend of HFC-32 and HFC125.
5. R-410A is nearly azeotropic--similar to R-22 and R-12. Although nearly azeotropic, charge with liquid refrigerant.
6. R-410A operates at 40-70% higher pressure than R-22, and systems designed for R-22 cannot withstand this higher pressure.
7. R-410A has an ozone depletion potential of zero, but must be reclaimed due to its global warming potential.
8. R-410A compressors use polyol ester oil.
9. Polyol ester oil is hygroscopic; it will rapidly absorb moisture and strongly hold this moisture in the oil.
10. A liquid line dryer must be used--even a deep vacuum will not separate moisture from the oil.
11. Limit atmospheric exposure to 15 minutes.
12. If compressor removal is necessary, always plug compressor immediately after removal. Purge with small amount of nitrogen when inserting plugs.
Topping Off System Charge
If a leak has occurred in the system, Bard Manufacturing recommends reclaiming, evacuating (see criteria above) and charging to the nameplate charge. If done correctly, topping off the system charge can be done without problems.
With R-410A, there are no significant changes in the refrigerant composition during multiple leaks and recharges. R-410A refrigerant is close to being an azeotropic blend (it behaves like a pure compound or single component refrigerant). The remaining refrigerant charge in the system may be used after leaks have occurred. "Top-off" the charge by utilizing the pressure charts on the inner control panel cover as a guideline.
Manual 2100-712F Page 22 of 38

REMEMBER: When adding R-410A refrigerant, it must come out of the charging cylinder/tank as a liquid to avoid any fractionation and to insure optimal system performance. Refer to instructions for the cylinder that is being utilized for proper method of liquid extraction.
Safety Practices
1. Never mix R-410A with other refrigerants.
2. Use gloves and safety glasses. Polyol ester oils can be irritating to the skin, and liquid refrigerant will freeze the skin.
3. Never use air and R-410A to leak check; the mixture may become flammable.
4. Do not inhale R-410A--the vapor attacks the nervous system, creating dizziness, loss of coordination and slurred speech. Cardiac irregularities, unconsciousness and ultimately death can result from breathing this concentration.
5. Do not burn R-410A. This decomposition produces hazardous vapors. Evacuate the area if exposed.
6. Use only cylinders rated DOT4BA/4BW 400.
7. Never fill cylinders over 80% of total capacity.
8. Store cylinders in a cool area, out of direct sunlight.
9. Never heat cylinders above 125°F.
10. Never trap liquid R-410A in manifold sets, gauge lines or cylinders. R-410A expands significantly at warmer temperatures. Once a cylinder or line is full of liquid, any further rise in temperature will cause it to burst.
Important Installer Note
For improved start up performance, wash the indoor coil with a dishwashing detergent.
R410-A Refrigerant Charge
This unit was charged at the factory with the quantity of refrigerant listed on the serial plate. AHRI capacity and efficiency ratings were determined by testing with this refrigerant charge quantity.
Table 5 shows nominal pressures for the units. Since many installation specific situations can affect the pressure readings, this information should only be used by certified technicians as a guide for evaluating proper system performance. They shall not be used to adjust charge. If charge is in doubt, reclaim, evacuate and recharge the unit to the serial plate charge.

COMPONENTRY

! WARNING
Electrical shock hazard.
Disconnect VAC power supply before servicing.
Failure to do so could result in electric shock or death.
High Pressure Switch
All W**A/W**L wall-mount air conditioner series models are supplied with a high pressure switch. The high pressure switch opens at 650 psi.
Three Phase Scroll Compressor Start Up Information
Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction.
However, three phase compressors will rotate in either direction depending upon phasing of the power. Since there is a 50-50 chance of connecting power in such a way as to cause rotation in the reverse direction, verification of proper rotation must be made. Verification of proper rotation direction is made by observing that suction pressure drops and discharge pressure rises when the compressor is energized. Reverse rotation also results in an elevated sound level over that with correct rotation, as well as substantially reduced current draw compared to tabulated values.
Verification of proper rotation must be made at the time the equipment is put into service. If improper rotation is corrected at this time, there will be no negative impact on the durability of the compressor. However, reverse operation for over 1 hour may have a negative impact on the bearing due to oil pump out.
NOTE: If compressor is allowed to run in reverse rotation for an extended period of time, the compressor's internal protector will trip.
All three phase compressors are wired identically internally. As a result, once the correct phasing is determined for a specific system or installation, connecting properly phased power leads to the same Fusite terminal should maintain proper rotation direction.
The direction of rotation of the compressor may be changed by reversing any two line connections to the unit.

Phase Monitor
Used only on 3-phase equipment, the phase monitor is a compressor protection device that will prohibit operation of the compressor if the device senses a possible reverse-rotation situation due to incorrect phasing. On a call for compressor (and only compressor), the device will check incoming phase, check for severe voltage imbalance and check for proper frequency. Under nominal conditions, a green LED light will show on the face of the monitor. If there is improper phasing, voltage imbalance or frequency deviation, the device will show a red LED light and prohibit compressor operation.
If a fault condition occurs, reverse two of the supply leads to the unit. Do not reverse any of the unit factory wires as damage may occur.

Condenser Fan Operation

NOTE:

On models equipped with a low ambient control (LAC), the condenser fan motor will have a delayed start until system refrigerant operating pressure builds up. After starting, the fan motor may or may not cycle depending upon ambient conditions. This is normal operation.

The condenser fan motor on 230/208 volt, one and three phase, 60 HZ units is a two-speed motor that comes factory wired on high speed for peak performance.

Low Ambient Control
Modulating head-pressure control that allows full speed at pressures above 315 psi. Below 315 psi, the control will slow fan speed--following internal head pressures--until a minimum RPM is reached (approx 300 RPM). Below this point, the control will shut the fan completely off until internal pressures rise. The control is preset from the factory, but should adjustment become necessary, there is an adjustment screw located on the bottom of the control behind a weatherproof cap. One full turn clockwise equals approximately +48 psi.

Compressor Control Module
The compressor control module (CCM) is standard on all models covered by this manual.
Delay-on-Make Timer
A delay-on-make timer is included to be able to delay startup of the compressor. This is desired when more than one unit is on a structure so that all of the units do not start at the same time which could happen after a power loss or building shutdown. The delay-on-make time period is 2 minutes plus 10% of the delay-onbreak time period. To ensure that all of the units do not

Manual 2100-712F Page 24 of 38

start at the same time, adjust the delay-on-break timer on each unit to a slightly different delay time.
Short Cycle Protection/Delay-on-Break
An anti-short cycle timer is included to prevent short cycling the compressor. This is adjustable from 30 seconds to 5 minutes via the adjustment knob (see Figure 31). Once a compressor call is lost, the time period must expire before a new call will be initiated.
10% of this time is also considered on the delay-onmake timer (see Delay-on-Make Timer).
High Pressure Detection
High pressure switch monitoring allows for a lockout condition in a situation where the switch is open. If the high pressure switch opens, the CCM will de-energize the compressor. If the switch closes, it will then restart the compressor after the delay-on-break setting has expired on the device. If the switch trips again during the same thermostat call, the compressor will be deenergized and the alarm terminal will be energized indicating an alarm. The red LED will light and stay on until power is cycled to the control or a loss of voltage is present at Y terminal for more than ½ second.

Test Mode
By rapidly rotating the potentiometer (POT) clockwise (see Figure 31), all timing functions will be removed for testing.
The conditions needed for the unit to enter test mode are as follows: POT must start at a time less than or equal to the 40 second mark. The POT must then be rapidly rotated to a position greater than or equal to the 280 second mark in less than ¼ second. Normal operation will resume after power is reset or after the unit has been in test mode for at least 5 minutes.
Brownout Protection with Adjustment
Brownout protection may be necessary if the utility power or generator power has inadequate power to prevent the voltage from dropping when the compressor starts. This is rare but can happen if the generator is undersized at the site or if the site is in a remote location far from the main power grid. Under normal circumstances, allowing the brownout to be ignored for a time period should not be needed. The 8201-171 is shipped in "0" do not ignore position, with all the DIP switches off (see Figure 31).

Manual 2100-712F

Page

If ignoring the brownout is needed because of the above conditions, three preset timers can be set by DIP switches in order to delay signaling a power brownout for a specific length of time after compressor contactor is energized. This allows the compressor a time period to start even if the voltage has dropped and allows the voltage to recover. This delay only happens when the CC terminal energizes. The delay can be set to 1 second (A DIP switch), 5 seconds (B DIP switch) or 10 seconds (C DIP switch); time is not cumulative--only the longest setting will apply. If the voltage recovers during the brownout delay period, the compressor will continue running.
If a brownout condition is detected by the 8201-171 at any point while there is a cooling call or power is on at Y, the troubleshooting light will flash blue. The light will continue to flash until the cooling call is satisfied or power is removed from the Y terminal. This condition does not prevent operation, it only indicates that a brownout condition was present at some point during the call. If a brownout condition is detected while CC has an output, CC will be deenergized and will retry after the delay-on-break timer is satisfied, honoring any DIP switch timer chosen when the CC output is re-energized; this process will continue until call is satisfied.
If inadequate utility or generator power continues after the Delay-on-Make or Delay-on-Break timer is fulfilled, the CC output will not energize. This could lead to the compressor never starting. The control will see the brownout immediately and not start.
A common scenario and one that has been seen in the field is when a unit or units switches from utility power to generator power. With slower transfer switches, the time delay between the utility power and generator power didn't cause a problem. The units lost power, shut off and came back on line normally. With the introduction of almost instantaneous transfer switches, the millisecond long power glitch can be enough that the compressor will start to run backwards.
Pressure Service Ports
High and low pressure service ports are installed on all units so that the system operating pressures can be observed. A pressure table covering all models can be found on page 23. It is imperative to match the correct pressure table to the unit by model number.
This unit employs high-flow Coremax valves instead of the typical Schrader type valves.
WARNING! Do NOT use a Schrader valve core removal tool with these valves. Use of such a tool could result in eye injuries or refrigerant burns!
To change a Coremax valve without first removing the refrigerant, a special tool is required which can be obtained at www.fastestinc.com/en/SCCA07H. See the replacement parts manual for replacement core part numbers.

MAINTENANCE AND TROUBLESHOOTING

Standard Maintenance Procedures
! WARNING
Electrical shock hazard. Disconnect all power supplies before servicing. Failure to do so could result in electric shock or death.
! CAUTION
Cut hazard. Wear gloves to avoid contact with sharp edges. Failure to do so could result in personal injury.
1. Disable system from LC6000 controller (see latest version of 2100-669 LC6000 Service Instructions manual).
2. Turn off AC breakers at wall-mount units.
3. Check inlet sides of condenser and evaporator coils for obstructions/debris--clean if necessary using a quality manufactured coil cleaning product specific for the evaporator or condenser coil.
· Condenser coil: Remove the fan shroud/ motor/motor bracket as an assembly from the condenser section. This will give clear access to the inlet side of the coil for cleaning. Follow the coil cleaner manufacturer's directions for necessary safety gear and precautions, as well as for application and use. More than one application may be necessary. Rinse thoroughly.
· Evaporator coil: Remove the evaporator section panel and apply specific evaporator cleaner directly to the inlet side of coil, being very careful not to overspray into insulation or surrounding panels and wiring. Residual cleaner and dissolved debris should drip into the drain pan and leave the unit through the condensate hose. More than one application may be necessary. Rinse thoroughly.

4. Manually spin fan and blower motors to ensure they turn freely. All motors are permanently lubricated, so no oil is necessary.
5. Inspect free cooling damper actuator and linkage.
6. Install new air filter; check for additional filter grilles internal to the structure.
7. Inspect the control panel of the system.
· Look for insect or rodent activity and remove any nesting materials.
· Manually push contactor closed, observe for movement--contactor points should have minimal discoloration, no spalling or other signs of arcing. Replace if doubtful.
· Check field and factory wiring for tightness and look for signs of overheating (discoloration of terminals or wire insulation).
8. Ensure that supply and return registers are not obstructed, and more importantly, are not recycling the air to one another. Adjust supply louvers if necessary to direct discharge air away from any direct route to the return grille.
9. Re-assemble wall-mount unit, turn breakers back on.
10. Enable system to LC6000 controller (see latest version of 2100-669 LC6000 Service Instructions manual).
11. Repeat steps for additional wall-mount units.
Removal of Fan Shroud
1. Disconnect all power to the unit.
2. Remove the screws holding both grilles, one on each side of unit, and remove grilles.
3. Remove nine screws holding fan shroud to condenser and bottom.
4. Unwire condenser fan motor.
5. Slide complete motor, fan blade and shroud assembly out the left side of the unit.
6. Service motor/fan as needed. Any service work requiring removal or adjustment in the fan and/or motor will require that the dimensions be checked and blade adjusted in or out on the motor shaft accordingly (see page 26 for proper clearance adjustment).
7. Reverse steps to re-install.

Dirty Filter Switch
1. Disconnect all power to the unit. Remove control panel outer cover and upper front panel.
2. The dirty filter switch is located on top of the filter partition to the right of the blower wheels on W**ABP units and to the left of the blower wheels on W**LBP units (see Figure 35). The dirty filter indicator light and reset switch is attached to the side of the control panel on the right side of the filter access opening on W**ABP units and on the left side of the filter access opening on W**LBP units. Remove the cover on the dirty filter switch and ensure the knob is set at 0.4" W.C. (see Figure 36). This is only a recommended starting point prior to making switch adjustments. Switch setting is highly dependent on filter type used, blower speed, unit ducting and other unit installation characteristics. See Dirty Filter Switch Adjustment for instructions how to make proper switch adjustments.
3. Re-install upper front panel.

Dirty Filter Switch Adjustment
1. Apply power to the unit.
2. Turn the unit indoor blower on (energize R-G on low voltage terminal board).
3. With air filters installed and switch initially set at 0.4" W.C. (see Step 2 under Dirty Filter Switch), begin restricting the air filter of the unit using a piece of cardboard under the filters until the switch trips and the light comes on. If the filter is restricted by 75% (or desired restriction amount), skip to Step 6.
4. If switch setting adjustment is required, disconnect power to the unit. Remove the upper front panel and the cover on the airflow switch so that adjustment can be made. If the switch tripped before 75% restriction was reached, turn the knob slightly clockwise. If the switch tripped after 75%, turn the knob counter-clockwise (see Figure 36).
5. Replace the upper front panel and repeat Steps 1-3. Continue to make adjustments described in Step 4 until the desired restriction is obtained.
6. Remove the restriction and reset the filter switch. Replace the switch cover once adjustment is complete.
7. Install the outer control panel cover. This completes the adjustment.

GENERAL INFORMATION

Air Conditioning System
This Bard air conditioning system is composed of MULTI-TEC wall-mounted air conditioners matched with an LC6000 supervisory controller, th-Tune singleunit controller or PGD stand-alone display. If only one wall-mounted air conditioner is being used, it can be matched with either the LC6000 supervisory controller, th-Tune or PGD (see Single Unit Operation on page 3 for information on the th-Tune and PGD). If more than one wall mount is installed, the LC6000 controller must be matched with the air conditioning units. The wall-mount units are specifically engineered for telecom/motor control center rooms.

NOTE: The LC6000 supervisory controller and MULTI-TEC wall-mount units are designed specifically to work together. The controller cannot run other brands of systems, nor can other controllers run the MULTI-TEC wall-mount units. They are a complete system, and must be used together.

Wall-Mount Air Conditioner Units
The MULTI-TEC units will supply 100% of rated cooling airflow in free cooling mode with ability to exhaust the same amount through the unit itself without any additional relief openings in the shelter.
MULTI-TEC units are fully charged with refrigerant and have optional electric heat.
Single Unit Operation
A PGD stand-alone display (Bard P/N 8620-306 or 8620-307) or th-Tune single-unit controller (Bard P/N 8403-088) can be used in place of the LC6000 controller when only one MULTI-TEC wall-mount air conditioner is being installed. If using a PGD or th-Tune instead of the LC6000 controller, the alarm logging and remote communication capabilities of the LC6000 controller will not be available. See PGD manual 2100-734 or th-Tune manual 2100-678 for information on installing and setting up a PGD or thTune for single unit operation. A TEC-EYE hand-held diagnostic tool is required to program the wall-mount unit for PGD or th-Tune operation. The th-Tune and TEC-EYE diagnostic tool are available as a kit (Bard P/N 8620-264).
General
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

SITE PREPARATION

Model Identification
Identify the specific model using the model nomenclature information found in Figure 1 and the model/serial tag found on the unit. See Figure 2 on page 8 for dimensions and critical installation requirements.
New Shelter Installation vs. Retrofit Installation
These installation instructions cover both new shelter installations and retrofit installations. Each installation is unique and may require special accommodations and modifications. Although Bard Manufacturing follows a long-established tradition of manufacturing equipment using industry standard dimensions for building penetration, it is occasionally necessary to move or enlarge supply and return openings when replacing non-standardized equipment in a retrofit application.
Minimum Clearance
Wall-mount air conditioners are available in both righthand access models and left-hand access models. Right-hand access models have the heat strip access panel, external circuit breakers access panel and internal controls access panel on the right side of the unit. Left-hand access models are a mirror image of the right-hand access models, and allow two wall-mount units to be placed in relatively close proximity and yet still allow complete access for maintenance and repair.
On side-by-side installations, maintain a minimum of 20" clearance on control side to allow access to control panel and heat strips, and to allow proper airflow to the outdoor coil. For installations where units are installed with both control panels facing each other (inward), maintain a minimum of 36" clearance to allow access. Additional clearance may be required to meet local or national codes.
Care should be taken to ensure that the recirculation and obstruction of condenser discharge air does not occur. Recirculation of condenser discharge air can be from either a single unit or multiple units. Any object such as shrubbery, a building or a large object can cause obstructions to the condenser discharge air. Recirculation or reduced airflow caused by obstructions will result in reduced capacity, possible unit pressure safety lockouts and reduced unit service life.
For units with blow through condensers, such as these wall-mount units, it is recommended there be a minimum distance of 10' between the front of the unit and any barrier or 20' between the fronts of two opposing (facing) units.

Clearance to Combustibles

! WARNING
Fire hazard.
Maintain minimum 1/4" clearance between the supply air duct and combustible materials in the first 3' of ducting.
Failure to do so could result in fire causing damage, injury or death.

The unit itself is suitable for 0" clearance, but the supply air duct flange and the first 3' of supply air duct require a minimum of 1/4" clearance to combustible material. However, it is generally recommended that a 1" clearance is used for ease of installation and maintaining the required clearance to combustible material. See Figures 4A and 4B on pages 10 and 11 for details on opening sizes.

WALL-MOUNT UNIT MOUNTING

Mounting the Units
! WARNING
Heavy item hazard.
Use more than one person to handle unit.
Failure to do so could result in unit damage or serious injury.
NOTE: It may be best to spot some electrical knockouts (such as those located on the back of the wall-mount unit) before units are mounted and access is unavailable or limited (see Figure 2 to locate pre-punched knockouts).
Two holes for the supply and return air openings must be cut through the wall as shown in Figures 4A and 4B on pages 10 and 11. On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration. All walls must be thoroughly inspected to ensure that they are capable of carrying the weight of the installed unit.
In retrofit (unit replacement) installations, the openings cut for the original equipment may not line up exactly with needs of this installation. Modifications may need to be made, such as increasing or decreasing the size of the wall cutouts. The existing bolt placement may not line up in which case the original bolts would need to be removed or cut away.
1. These units are secured by full-length mounting flanges built into the cabinet on each side which secure the unit to the outside wall surface. A bottom mounting bracket, attached to skid for shipping, is provided for ease of installation, but is not required.
2. The unit itself is suitable for 0" clearance, but the supply air duct flange and the first 3' of supply air duct require a minimum of 1/4" clearance to combustible material. However, it is generally recommended that a 1" clearance is used for ease of installation and maintaining the required clearance to combustible material. See Figures 4A and 4B for details on opening sizes.
3. Locate and mark lag bolt locations and location for optional bottom mounting bracket, if desired (see Figures 4A and 4B).
4. Mount bottom mounting bracket (if used).

5. If desired, hook top rain flashing (attached to frontright of supply flange for shipping) under back bend of top.
6. Position unit in opening and secure with fasteners sufficient for the application such as 5/16" lag/ anchor/carriage bolts; use 7/8" diameter flat washers on the lag bolts. It is recommended that a bead of silicone caulking be placed behind the side mounting flanges.
7. Secure optional rain flashing to wall and caulk across entire length of top (see Figures 4A and 4B).
8. For additional mounting rigidity, the return air and supply air frames or collars can be drilled and screwed or welded to the structural wall itself (depending upon wall construction). Be sure to observe required clearance if combustible wall.
9. A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage.
10. Install outdoor temperature/humidity sensor (see Figure 3). Remove grommet from base and sensor. Discard shipping bracket. Place sensor extension through hole in base under condenser fan and secure to base with screw.

PRELIMINARY START UP

Running in Orphan Mode
With the AC breakers turned on, each MULTI-TEC wall-mount unit has the capability to run without the LC6000 controller or PGD connected--this feature is called orphan mode. This keeps the shelter between 60°F and 77°F (factory default settings) by the use of the factory-installed return air sensor in each wallmount unit. In orphan mode, the wall unit uses a continuous blower setting to circulate room air into the return air inlet and uses the return air temperature sensor to control room temperature.
The wall-mount unit can be turned on and off with the TEC-EYE hand-held diagnostic tool. When ON is chosen, the wall-mount unit will heat or cool. When set to OFF using the TEC-EYE, the wall-mount unit will not heat, cool or ventilate.
To turn the unit on or off with TEC-EYE:
1. Connect the TEC-EYE diagnostic tool to the control board located in the unit.
2. Press MENU key to go to the Main Menu screen.
3. Press UP or DOWN keys and ENTER key to enter USER password 2000.
4. Press UP or DOWN keys to scroll to On/Off; press ENTER key.
5. Press UP or DOWN keys to change value from On to Off or from Off to On.
6. Press ESCAPE key several times to return to Main Menu screen.
To verify or change the wall-mount unit cooling and heating setpoints in orphan mode:
1. Connect the TEC-EYE diagnostic tool to the control board located in the unit.
2. From the Status screen, press UP or DOWN key until Quick Menu displays Setpoints (SET) icon. Press ENTER key.
3. Press ENTER key to scroll to the selected choice (see Figure 11).
4. Press UP or DOWN key on desired value until value displays correctly.
5. Press ENTER key to save and scroll to next parameter.
6. Press ESCAPE key until Main Menu screen is displayed.

FIGURE 11 Cooling and Heating Setpoints
During installation, the ability to run in orphan mode allows deactivation of one of the existing, older wallmount units, while keeping the shelter cool with the other unit still operating. Once the first of the Bard MULTI-TEC wall-mount units is installed, orphan mode can be enabled early in the installation--keeping the climate inside the shelter stable and the installers comfortable while the remainder of the older equipment is removed and the remaining Bard MULTI-TEC wallmount units and LC6000 controller are installed. Additionally, should any or all of the MULTI-TEC wallmount units lose communication with the LC6000 controller (such as during maintenance), they will continue to serve the shelter's needs until a repair can be made. NOTE: Screenshots shown in this manual reflect
default settings (when applicable).

! WARNING
Electrical shock hazard.
Disconnect VAC power supplies before servicing.
Failure to do so could result in electric shock or death.
IMPORTANT: When working with circuit board components, Bard recommends the use of an anti-static wrist strap to prevent static electricity shorts to electronic controls.
LC6000 Controller
The LC6000 controller is part of this air conditioning system. It is used to control up to 14 wall-mount air conditioners from one controller. The microprocessor control provides an easy-to-read interface with large LCD graphical display. It provides control for redundancy for the structure and equal wear on all units.
Conduit is recommended for all wiring. Route communication wiring and power supply wiring in their own separate conduits.
The LC6000 controller is not weatherproof and is intended for use in a weathertight structure.

Mounting the LC6000 Controller
The dimensions of the LC controller are 16" x 12" x 6".
Because the LC6000 controller utilizes a remote temperature sensor as opposed to one located in the controller box, the controller itself can be installed in any indoor location that is suitable, preferably at eye level. Four (4) mounting holes are provided for mounting to the wall and holes for conduit connections are provided in the base, sides and top of the controller.
The LC6000 controller includes four fused power supply terminals in the terminal block. Before connecting wires to the terminal block, confirm that the fuse in each of the four fuse holders is in the proper position (active) as shown in Figure 13.

Installing Remote Indoor Temperature/Humidity Sensor(s)
One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Locating the sensor between both return grilles is often the best location, but every installation is unique. Location height should be approximately 60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire conduit. Use shielded cable to connect to controller. The maximum cable length to connect the temperature/humidity sensor to the LC6000 is 98'.

2. Connect the other end of the shielded cable to the sensor terminals. Be sure wires are connected to proper terminals as shown in table above. Sensor jumpers need to be positioned for 0-1 V. With sensor oriented as shown in image to right, move both jumpers to right position (DP1 and DP2 set to OFF). This applies to all indoor temperature/humidity sensors connected to the LC controller. See illustration mounted inside of sensor cover for further detail on jumper position. Earlier versions of this sensor may be mounted in a different orientation which would affect the positioning of the sensor jumpers. See page 44 for additional information on sensor orientation.

For proper operation, the remote indoor temperature/humidity sensor (and any additional sensors) must be configured properly with the controller as shown in Step 2 on page 22. An additional remote indoor temperatureonly sensor can be purchased and installed in Zone 1. If the site in which the LC6000 controller will be used has more than one zone (maximum three zones per LC6000), additional remote temperature/humidity sensors (one per zone) will need to be purchased and installed in the additional zones. All installed sensors must be enabled in the controller menu (see Configure Sensors beginning on page 37).
FIGURE 15 Additional Remote Temperature and Temperature/Humidity Sensor Installation
One additional temperature sensor can be added to Zone 1 and additional temperature/humidity sensors may be added to Zones 2 and 3 (one per zone). Be sure the sensors are connected to the proper terminals on the terminal block and sensor as listed below. The maximum cable length to connect temperature or temperature/humidity sensors to the LC6000 is 98'.

Communication Wiring
Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 18, 19 or 20. The daisy chain does not need to follow the addressing order. The communication wire should be 2-wire, 18 gauge shielded cable with drain. Any color can be used. Be sure to match "+" and "-" symbols on controller terminal blocks to prewired unit control terminal block (see Figures 22 and 23 on pages 29 and 30). Attach communication wire filters as shown in Figures 18, 19 or 20. Do not run communication wiring in same conduit as supply wiring. Route communication wiring and power supply wiring in their own separate conduits.

Remote Indoor Temperature/Humidity Sensor Orientation
Current versions of the remote indoor temperature/ humidity sensor need to be installed with the shielded cable wires entering the bottom of the back of the sensor to connect to the sensor terminals (see Figure 47). Earlier versions of this sensor were installed so that the sensor wires entered through the top of the back of the sensor (see Figure 48). The orientation of the sensor affects the position of the DP1/DP2 jumpers. Depending on how the sensor is installed, be sure to confirm that the jumpers are in the proper position for the 0-1 V setting as shown in the figures below.
This applies to all indoor temperature/humidity sensors connected to the LC controller. See illustration mounted inside of sensor cover for further detail on jumper position.
