Introduction
These Fan Coils are designed for installation flexibility. The units leave the factory compliant with low leak requirements of less than 2% cabinet leakage rate at 1.0 inches W.C. and 1.4% cabinet leakage rate at 0.5 inches W.C. when tested in accordance with ASHRAE 193 standard. All these fan coils use a multi-tap ECM motor for efficiency. The units have be designed for upflow, downflow (kit required), and horizontal orientations, including manufactured and mobile home applications.
IMPORTANT: These units are designed specifically for R-454B refrigerant and must be used only with R-454B refrigerant air conditioners and heat pumps as shipped.
IMPORTANT: This unit MUST be installed in a location that is LOWER than 600 meters above sea level. These units are available for systems of 18,000 through 60,000 BTUh nominal cooling capacity. Factory- authorized, field - installed electric heater packages are available in sizes 5 through 30kW. See Product Data literature for all available accessory kits.
Heater Packages
NOTE: Some heater sizes may require the removal of two screws which connect the blower housing to the fan deck (removal will not impact performance). See (Care and Maintenance on p14) and Fig. 25.
This unit may or may not be equipped with an electric heater package. For units not equipped with factory-installed heat, a factory-approved, field-installed, UL listed heater package is available from your equipment supplier. See unit rating plate for a list of factory-approved heaters. Heaters that are not factory approved could cause damage which would not be covered under the equipment warranty. If fan coil contains a factory-installed heater package, minimum circuit ampacity (MCA) and maximum fuse/breaker may be different than units with a same size field-installed accessory heater. The differences is not an error and is due to calculation difference per UL guidelines.

This process accommodates small scuttle holes and limiting entrances to installation sites (Fig. 2).To disassemble the unit, disconnect the 4-pin sensor wire harness at the dissipation board and undo the wire routing in the cabinet. Remove the rear corner brackets by removing 2 screws which secure the brackets. Remove either 2 screws in each front corner of the coil box, or 2 screws in the blower box. Do not remove all 4 screws in each corner. Sections may now be separated by lifting the top section from the lower section. To reassemble, reverse above procedure. Be certain to reinstall all fasteners when reassembling.
Manufactured and Mobile Home Housing Applications
1. Secure the fan coil to the structure using field-supplied hardware.
2. Allow a minimum of 24" (610 mm) clearance from access panels.
3. Recommended method of securing for typical applications: a. If fan coil is away from wall, attach pipe strap to top of fan coil using no. 10 self-tapping screws. Angle strap down and away from back of fan coil, remove all slack, and fasten to wall stud of structure using 5/16" lag screws. Typical both sides of fan coil. b. If fan coil is against wall, secure fan coil to wall stud using 1/8" (3 mm) thick right-angle brackets. Attach brackets to fan coil using no. 10 self-tapping screws and to wall stud using 5/16" lag screws (Fig. 2).

! CAUTION
PRODUCT OR PROPERTY DAMAGE HAZARD Failure to follow this warning caution may result in product or property damage. The conversion of the fan coil to downflow requires special procedures for the condensate drains on both A-coil and Slope-coil units. The vertical drains have an overflow hole between the primary and secondary drain holes. This hole is plugged for all applications except downflow, and must be used for downflow. During conversion process, remove plastic cap covering vertical drains only and discard. Remove plug from overflow hole and discard. At completion of downflow installation, caulk around vertical pan fitting to door joint to retain low air leak performance of the unit.
Horizontal Installation
Units must not be installed with access panels facing up or down. All other units are factory built for horizontal left installation (Fig. 4 and Fig. 5). When suspending unit from ceiling, dimples in casing indicate suitable location of screws for mounting metal support straps (Fig. 4). For horizontal applications having high return static and humid return air, the Water Management Kit may need to be used to assist in water management. See the Product Data or contact your supplier for the kit number. NOTE: Modular units can be disassembled and components moved separately to installation area for reassembly. This process accommodates small scuttle holes and limiting entrances to installation sites (Fig. 9).

Air Ducts
Connect supply-air duct over the outside of ¾" (19 mm) flanges provided on supply-air opening. Secure duct to flange, using proper fasteners for type of duct used, and seal duct-to-unit joint. If return-air flanges are required, install factory-authorized accessory kit.
Use flexible connectors between ductwork and unit to prevent transmission of vibration. When electric heater is installed, use heat-resistant material for flexible connector between ductwork and unit at discharge connection. Ductwork passing through unconditioned space must be insulated and covered with vapor barrier.
Units equipped with 20-30kW electric heaters require a 1" (25 mm) clearance to combustible materials for the first 36" (914 mm) of supply duct. All 18,000 BTU units equipped with 8 or 10 kW electric heaters require a 1" (25.4 mm) clearance to combustible materials for the first 12" of supply duct.
If the appliance is connected via an air duct system to one or more rooms, the supply and return air shall be directly ducted to the space. Open areas such as false ceilings shall not be used as a return air duct. Any auxiliary devices installed in the ductwork should be approved by the manufacturer or declared suitable with the R-454B refrigerant.

! WARNING
EXPLOSION AND PERSONAL HEALTH HAZARD Failure to follow this warning could result in personal injury, death, and/or unit damage. Ensure to keep any required ventilation openings clear of obstruction. Air ducts connected to the appliance shall not contain a POTENTIAL IGNITION SOURCE. Auxiliary devices which may be a POTENTIAL IGNITION SOURCE shall not be installed in the duct work. Examples of such POTENTIAL IGNITION SOURCES are hot surfaces with a temperature exceeding 1292°F (700°C) and electric switching devices. Ensure only manufacturer approved auxiliary devices are installed.
Ductwork Acoustical Treatment
Metal duct systems that do not have a 90° elbow and 10 feet of main duct before first branch takeoff may require internal acoustical insulation lining. As an alternative, fibrous ductwork may be used if constructed and installed in accordance with the latest edition of SMACNA construction standard on fibrous glass ducts. Both acoustical lining and fibrous ductwork shall comply with National Fire Protection Association as tested by UL Standard 181 for Class 1 air ducts.
Electrical Connections
Units from the factory protect the low voltage circuit with a 3A automotive type fuse in-line on the wire harness. Motor speeds and time delay function are built into the motor. See (Minimum CFM and Motor Speed Selection on p8) for clarification. When a factory-approved accessory control package has been installed, check all factory wiring per unit wiring diagram and inspect factory wiring connections to be sure none were loosened during transit or installation. If a different control package is required, see unit rating plate. Before proceeding with electrical connections, make certain that supply voltage, frequency, phase, and ampacity are as specified on the unit rating plate. See unit wiring label for proper field high- and low-voltage wiring. Make all electrical connections in accordance with the NEC and any local codes or ordinances that may apply. Use copper wire only. The unit must have a separate branch electric circuit with a field-supplied disconnect switch located within sight from, and readily accessible from, the unit. On units with a factory-installed disconnect with pull-out removed, service and maintenance can be safely performed on only the load side of the control package.

PF5M: Installation Instructions
! WARNING
ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death. Field wires on the line side of the disconnect found in the fan coil unit remain live, even when the pull-out is removed. Service and maintenance to incoming wiring cannot be performed until the main disconnect switch (remote to the unit) is turned off.
Line Voltage Connections
If unit contains an accessory electric heater, remove and discard power plug from fan coil and connect male plug from heater to female plug from unit wiring harness. (See Electric Heater Installation Instructions.) For units without electric heat: 1. Connect 208/230V power leads from field disconnect to yellow and
black stripped leads. 2. Connect ground wire to unit ground lug. NOTE: Units installed without electric heat should have a field-supplied sheet metal block-off plate covering the heater opening. This will reduce air leakage and formation of exterior condensation.
24V Control System Connection To Unit
Wire low voltage in accordance with wiring label on the blower (Fig. 10 thru Fig. 13). Use #18 AWG color-coded, insulated (35° C minimum) wire to make the low-voltage connections between the thermostat, the unit, and the outdoor equipment. If the thermostat is located more than 100' (30 m) from the unit (as measured along the low-voltage wire), use #16 AWG color-coded, insulated (35° C minimum) wire. All wiring must be NEC Class 1 and must be separated from incoming power leads. Refer to outdoor unit wiring instructions for any additional wiring procedure recommendations.

PF5M: Installation Instructions
To change motor speeds disconnect the BLUE fan lead from motor connector terminal #2 (factory default position) and move to desired speed-tap; 1, 2, 3, or 5.
Speed-taps 1, 2, and 3 have a 90 second blower off time delay pre-programmed into the motor. Speed-tap 4 is used for electric heat only (with 0 second blower time delay) and the WHITE wire should remain on tap 4. Speed-tap 5 is used for high static applications, but has a 0 second blower time delay pre-programmed into the motor. See Airflow Performance tables for actual CFM. Se Fig. 15 for motor speed selection location.
NOTE: In low static applications, lower motor speed tap should be used to reduce possibility of water being blown off coil.
Refrigerant Tubing Connection and Evacuation
Use accessory tubing package or field-supplied tubing of refrigerant grade. Suction tube must be insulated. Do not use damaged, dirty, or contaminated tubing because it may plug refrigerant flow-control device. ALWAYS evacuate the coil and field-supplied tubing to 500 microns before opening outdoor unit service valves.
! CAUTION
PRODUCT DAMAGE HAZARD
Failure to follow this caution may result in product or property damage.
A brazing shield MUST be used when tubing sets are being brazed to the unit connections to prevent damage to the unit surface and condensate pan fitting caps.
Units have sweat suction and liquid tube connections. Make suction tube connection first.
IMPORTANT: Federal regulations require that you do not vent refrigerant to the atmosphere. Recover during system repair or final unit disposal.
Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends.
Make provision for expansion and contraction of long piping runs. Protect piping and fittings as much as possible against adverse
environmental effects; for example, the danger of water collecting and freezing in relief pipes or the accumulation of dirt and debris. Install piping to reduce the likelihood of hydraulic shock damaging the system. Always use certified steel piping and components to protect against corrosion. Protect flexible pipe elements against mechanical damage and excessive stress by torsion or other forces. Check flexible pipes for mechanical damage annually.
1. Cut tubing to correct length.
2. Insert tube into sweat connection on unit until it bottoms.
3. All fittings need to withstand 700 PSIG (Mechanical Fittings or Brazing). When brazing, use silver bearing or non-silver bearing brazing material. Do not use solder (materials which melt below 800° F / 427° C). Consult local code requirements.
4. Perform a pressure check of the unit with a nitrogen charge of about 200psi. The Nitrogen holding charge must not decrease in pressure for 1 hour.
5. Perform leak check on the unit. Vacuum unit to 500 microns. When isolating the unit from the pump, the pressure shall not rise above 1500 microns in 10 minutes.

Mechanical Line Set Connections
If using mechanical or crimp-type line set connections, follow crimp tool manufacturer's instructions. NOTE: Should the use of mechanical fittings cause failure of the fittings or failure of the equipment, such would not be covered under the standard warranty.
! CAUTION
PRODUCT DAMAGE HAZARD Failure to follow this caution may result in product or property damage. Wrap a wet cloth around rear of fitting to prevent damage to TXV and factory-made joints.
Refrigerant Flow-Control Device
The 18-60 size units come equipped with an R-454B refrigerant mechanical TXV. When tightening nuts on a TXV, do not exceed 20 ft-lbs. Always use outdoor units designed to match indoor fan coil applications.
! CAUTION
PRODUCT OPERATION HAZARD Failure to follow this caution may result in improper product operation. If using a TXV in conjunction with a single-phase reciprocating compressor, a compressor start capacitor and relay are required. Consult outdoor unit pre-sale literature for start assist kit part number.
Disassembly
! WARNING
PERSONAL INJURY HAZARD Failure to follow this warning could result in personal injury. Remove refrigerant charge from system and ensure there is no pressure before servicing the TXV.
NOTE: For Item #1 (Fig. 16): Use an adjustable wrench with a backup adjustable wrench to loosen the brass nut (TXV outlet). Then use both wrenches to loosen Item # 2 (TXV inlet). 1. Use an adjustable wrench with a backup adjustable wrench to

PF5M: Installation Instructions

! CAUTION
UNIT OR PROPERTY DAMAGE HAZARD Failure to follow this warning caution may result in product or property damage. The conversion of the fan coil to downflow requires special procedures for the condensate drains on both A-coil and Slope-coil units. The vertical drains have an overflow hole between the primary and secondary drain holes. This hole is plugged for all applications except downflow, and must be used for downflow. During conversion process, remove plastic cap covering vertical drains only and discard. Remove plug from overflow hole and discard. At completion of downflow installation, caulk around vertical pan fitting to door joint to retain low air leak performance of the unit.

Fig. 16 Mechanical TXV Removal

A230489

! CAUTION
UNIT DAMAGE HAZARD Failure to follow this Caution may result in unit damage. Failure to place insulation between copper tubes and aluminum parts will lead to galvanic corrosion, which will result in a refrigerant leak in the future.
5. Use a wire tie to mount the 1/8" TXV equalizer and bulb tubes to the vapor header tube. Make sure that there is insulation between the aluminum vapor tube and copper tube.
6. Leak test the TXV fittings, then evacuate and charge the system to the required subcooling per the outdoor unit rating plate.
Condensate Drains
To connect drains, the cap openings must be removed. Use a knife to start the opening near the tab and using pliers, pull the tab to remove the disk. Clean the edge of the opening if necessary and install the condensate line. Finally caulk around the lines where they exit the fitting to retain the low leak rating of the unit. Units are equipped with primary and secondary ¾" FPT drain connections. For proper condensate line installations see Fig. 3 thru Fig. 7. To prevent property damage and achieve optimum drainage performance, BOTH primary and secondary drain lines should be installed and include properly-sized condensate traps (Fig. 17 and Fig. 22). Factory-approved condensate traps are available. It is recommended that PVC fittings be used on the plastic condensate pan. Finger-tighten plus 1-1/2 turns. Do not over-tighten. Use pipe dope. NOTE: Do not use CPVC in field drain lines due to potential reaction with POE oil. NOTE: When connecting condensate drain lines, avoid blocking filter access panel, thus preventing filter removal. After connection, prime both primary and secondary condensate traps.
! CAUTION
PRODUCT DAMAGE HAZARD Failure to follow this caution may result in product or property damage. Use only full size P-traps in the condensate line (Fig. 17). Shallow running traps are inadequate and DO NOT allow proper condensate drainage (Fig. 18).

Fig. 17 Recommended Condensate Trap

A03002

Fig. 18 Insufficient Condensate Trap

A03013

NOTE: If unit is located in or above a living space where damage may result from condensate overflow, a field-supplied, external condensate pan should be installed underneath the entire unit, and a secondary condensate line (with appropriate trap) should be run from the unit into the pan. Any condensate in this external condensate pan should be drained to a noticeable place. As an alternative to using an external condensate pan, some localities may allow the use of a separate ¾" (19 mm) condensate line (with appropriate trap) to a place where the condensate will be noticeable. The owner of the structure must be informed that when condensate flows from the secondary drain or external condensate pan, the unit requires servicing or water damage will occur.

Install traps in the condensate lines as close to the coil as possible. (Fig. 22). Make sure that the outlet of each trap is below its connection to the condensate pan to prevent condensate from overflowing the drain pan. Prime all traps, test for leaks, and insulate traps if located above a living area. Condensate drain lines should be pitched downward at a minimum slope of 1" (25 mm) for every 10' (3 m) of length. Consult local codes for additional restrictions or precautions.

NOTES: 1.Airflow based upon dry coil at 230V with factory-approved filter and electric heater (2 element heater sizes 18 through 36, 3 element heater sizes 42 through 60). 2.To avoid potential for condensate blowing out of drain pan prior to making drain trap: Return static pressure must be less than 0.40 in. wc. Horizontal applications of 42 - 60 sizes must have supply static greater than 0.20 in. wc. Airflow above 400 cfm/ton on 48-60 size could result in condensate blowing off coil or splashing out of drain pan.
