INDUSTRY LEADING FEATURES / BENEFITS

A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT
The 45MBFA series ductless system are a matched combination of an outdoor condensing unit and an indoor fan coil unit connected only by refrigerant tubing and wires.

The fan coil can be mounted on the floor or against the wall. This selection of fan coils permits creative solutions to design problems such as:

• Add-ons to current space (an office or family room addition)
• Special space requirements
• When changes in the load cannot be handled by the existing system
• When adding air conditioning to spaces that are heated by hydronic or electric heat and have no ductwork
• Historical renovations or any application where preserving the look of the original structure is essential.
  • The ideal compliment to your ducted system when it is impractical or prohibitively expensive to use ductwork.
  • The compact indoor fan coil units take up very little space in the room and do not obstruct windows. The fan coils are attractively styled to blend with most room decors. Advanced system components incorporate innovative technology to provide reliable cooling performance at low sound levels.

LOW SOUND LEVELS
When noise is a concern, the ductless systems are the answer. The indoor units are whisper quiet. There are no compressors indoors, either in the conditioned space or directly over it, and there is none of the noise usually generated by air being forced through ductwork.

SECURE OPERATION
If security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to prevent intruders from crawling through ductwork. In addition, since outdoor units can be installed close to an outside wall, coils are protected from vandals and severe weather.

SIMPLE SERVICING AND MAINTENANCE

• Removing the top panel on the outdoor units provides immediate access to the control compartment, providing a service technician access to check the unit’s operation. In addition, the draw-thru design of the outdoor section means that dirt accumulates on the outside surface of the coil. Coils can be cleaned quickly from the inside using a pressure hose and detergent.
• On all indoor units, service and maintenance expense is reduced due to easy-to-use cleanable filters. In addition, these console systems have extensive self-diagnostics and a refrigerant leak detection and mitigation system to assist in troubleshooting.

AN ELEGANT AND COMPACT DESIGN

• The look of newly-upgraded console unit features flowing lines that is aesthetic enough.
• Its unobtrusive design can easily fit into most interiors with different decorating-schemes.
• The width of the machine has been reduced by 10mm, taking less space.

A PERFECT CHOICE FOR NEW BUILDINGS AND RENOVATION PROJECTS

• Console unit can be installed standing on the floor, or wall-mounted
• It is a great option for radiator replacement in order to save your space while provide more functions.

Dual Air Outlets With Larger Dimension
Efficiently improve air volume, providing constant, quick cooling and heating throughout whole year.

BUILT-IN RELIABILITY

• Ductless system indoor and outdoor units are designed to provide years of trouble-free operation.
• The console indoor units include protection against freeze-up and high evaporator temperatures on heat pumps.
• The condensing units on heat pumps are protected by a three-minute time delay before the compressor starts the over-current protection and high temperature protection.

INDIVIDUAL ROOM COMFORT
Maximum comfort is provided because each space can be controlled individually based on usage pattern. The air sweep feature provided permits optimal room air mixing to eliminate hot and cold spots for occupant comfort. In addition, year-round comfort can be provided with heat pumps.

ECONOMICAL OPERATION
The ductless system design allows individual room heating or cooling when required. There is no need to run large supply-air fans or chilled water pumps to handle a few spaces with unique load patterns. In addition, because air is moved only in the space required, no energy is wasted moving air through ducts.

EASY-TO-USE CONTROLS
The console units have microprocessor-based controls to provide the ultimate in comfort and efficiency. The user friendly wireless remote control provides the interface between user and the unit.

ACCESSORIES
Customizing these ductless systems to your application is easily accomplished. Adding a condensate pump accessory to the console fan coil provides installation flexibility.

APPLICATION DATA

Unit Selection

• Select equipment to either match or is slightly less than the anticipated peak load. This provides better humidity control, fewer unit cycles, and less part-load operation.
• For units used in spaces with high sensible loads, base equipment selection on unit sensible load, not on total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment.

Unit Mounting (Indoor)
Refer to the unit’s installation instructions for further details.

• Unit leveling – For reliable operation, units should be level in all planes.
• Clearance – Provide adequate clearance for airflow (Fig. 4).
• Unit location – Select a location which provides the best air circulation for the room.

These units should be positioned on the floor, against the wall for the best air circulation. The unit return and discharge should not be obstructed by furniture, curtains, or anything which may cause unit short cycling or air recirculation. Place the unit in the middle of the selected wall (if possible). Use an outside wall, if available, to make piping easier, and place the unit so it faces the normal location of room occupants.

Mounting Template

• Refer to the unit’s installation instructions for further details.
• The fan coil units are furnished with mounting to mark the location of the wiring, and refrigeration line hole locations.

Support
Adequate support must be provided to support the weight of the
fan coil. Refer to “DIMENSIONS AND CLEARANCES” on page 5 and “SPECIFICATIONS” on page 6 for the fan coil weight, and the base unit dimensional drawings (in the installation instructions) for the mounting brackets location.

NOTE: Reference the product installation instructions for more information.

Drain Connections

Install drains to meet the local plumbing codes. If adequate gravity drainage cannot be provided, the unit should be equipped with an accessory condensate pump. Drain size is 5/8 in (16mm).

Refrigerant Lines

General Refrigerant Line Sizing:

1. The outdoor units are shipped with a full charge of r454b refrigerant.
2. Refrigerant lines should not be buried in the ground. If it is necessary to bury the lines, not more than 36-in (914 mm) should be buried. Provide a minimum 6-in (152 mm) vertical rise to the service valves to prevent refrigerant migration.
3. Both lines must be insulated. Use a minimum of 1/2-in. (12.7 mm) thick insulation. Closed-cell insulation is recommended in all long-line applications.
4. Special consideration should be given to isolating the interconnecting tubing from the building structure. Isolate the tubing so that vibration or noise is not transmitted into the structure.

WIRING
All wires must be sized per NEC (National Electrical Code) or CEC (Canadian Electrical Code) and local codes. Use Electrical Data table MCA (minimum circuit amps) and MOCP (maximum over current protection) to correctly size the wires and the disconnect fuse or breakers respectively.

Recommended Connection Method for Power and Communication Wiring:

• The main power is supplied to the outdoor unit. The field supplied 14/3 stranded wire with ground with a 600 volt insulation rating, power/communication wiring from the outdoor unit to indoor unit consists of four (4) wires and provides the power for the indoor unit. Two wires are line voltage AC power, one is communication wiring (S) and the other is a ground wire. Wiring between indoor and outdoor unit is polarity sensitive. The use of BX wire is NOT recommended.
• If installed in a high Electromagnetic field (EMF) area and communication issues exists, a 14/2 stranded shielded wire can be used to replace L2 and (S) between outdoor unit and indoor unit landing the shield onto ground in the outdoor unit only.

EQUIPMENT DAMAGE HAZARD

• Failure to follow this caution may result in equipment damage or improper operation.
• Wires should be sized based on NEC and local codes.
• Failure to follow this caution may result in equipment damage or improper operation.
• Be sure to comply with local codes while running wire from the indoor unit to the outdoor unit.
• Every wire must be connected firmly. Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard may also exist. Ensure all wiring is tightly connected.
• No wire should touch the refrigerant tubing, compressor or any moving parts.
• Disconnecting means must be provided and shall be located within sight and readily accessible from the air conditioner.
• Connecting cable with conduit shall be routed through the hole

CONTROL SYSTEM

The unit is equipped with a microprocessor control to perform two functions:

1. Provide safety for the system
2. Control the system and provide optimum levels of comfort and efficiency.

• The main microprocessor is located on the control board of the fan coil unit (outdoor units have a microprocessor too) with thermistors located in the fan coil air inlet and on the indoor coil.
• Heat pump units have a thermistor on the outdoor coil. These thermistors monitor the system operation to maintain the unit within acceptable parameters and control the operating mode.

Wireless Remote Control

1. A wireless remote control is supplied for system operation of the console units.
2. Each battery operated wireless (infrared) remote control may be used to control more than one unit.

Wired Remote Control (Optional)

1. Optional wired remote controller used for system operation of all console units.
2. Kit includes a wired remote controller and a connecting cable.
3. Connect the wire terminal between the remote controller and the indoor unit.
4. Displays in °F or °C and temperature increments every 1°F increment/0.5°C increment.
