Product Data

INDUSTRY LEADING FEATURES / BENEFITS

A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT.

The 38/40MFC(Q) series ductless split systems 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 is mounted on the wall, near the ceiling. This selection of fan coils permits creative solutions to design problems such as:

S Add--ons to current space (an office or family room

addition)

S Special space requirements

S When changes in the load cannot be handled by the

existing system.

S When adding air conditioning to spaces that are heated

by hydronic or electric heat and have no ductwork.

S 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.

These 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 split 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.

When sound ordinances and proximity to neighbors demand quiet operation, the 38MFC,MFQ unit is the right choice: The advanced, horizontal airflow design distributes air more evenly over the coil.

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 38MFC,MFQ units can be installed close to an outside wall, coils are protected from vandals and severe weather.

FAST INSTALLATION

This compact ductless split system is simple to install. A mounting bracket is standard with the indoor units and only wire and piping need to be run between indoor and outdoor units. These units are fast and easy to install ensuring minimal disruption to customers in the home or workplace. This makes the 38/40MFC,MFQ ductless split systems the equipment of choice, especially in retrofit situations.

SIMPLE SERVICING AND MAINTENANCE

Removing the top panel on outdoor units provides immediate access to the control compartment, providing a service technician access to check unit 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 high wall systems have extensive self--diagnostics to assist in troubleshooting.

BUILT--IN RELIABILITY

Ductless split system indoor and outdoor units are designed to provide years of trouble--free operation.

The high wall 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 will start the over--current protection and the 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 split 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 high-- wall 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 split systems to your application is easily accomplished.

Adding a condensate pump accessory to the high wall fan coil provides installation flexibility.

APPLICATION DATA

UNIT SELECTION

Select equipment to either match or be slightly less than 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 unit Installation Instructions for further details. Unit leveling -- For reliable operation, units should be level in all

planes. Clearance -- Provide adequate clearance for airflow as shown in

Fig. 2. Unit location -- Select a location which will provide the best air

circulation for the room. These units should be positioned as high as possible on the wall for

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.

UNIT MOUNTING (OUTDOOR)

Refer to unit Installation Instructions for further details. Unit leveling -- For reliable operation, units should be level in all

planes. Clearance -- Minimum clearance, as shown in Fig. 3, must be

provided for airflow. The condensing units are designed for free--blow application. Air inlets and outlets should not be restricted.

Unit location -- A location which is convenient to installation and not exposed to strong wind.

A location which can bear the weight of outdoor unit and where the outdoor unit can be mounted in a level position.

Do not install the indoor or outdoor units in a location with special environmental conditions. For those applications, contact your Carrier representative.

MOUNTING TEMPLATE

Refer to unit 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 all fan coils. Refer to the Physical Data section for fan coil weights, and the base unit dimensional drawings for the location of mounting brackets.

REFRIGERANT LINES

General refrigerant line sizing:

1. The 38MFC/MVQ units are shipped with a full charge of R410A refrigerant. All charges, line sizing, and capacities are based on runs of 25 ft (7.6 m). For runs over 25 ft (7.6 m), consult long--line section on this page for proper charge adjustments.

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 interconnecting tubing from the building structure. Isolate the tubing so that vibration or noise is not transmitted into the structure.

Long Line Applications, 38MFC Units:

1. No change in line sizing is required.

2. Add refrigerant per table below.

WIRING

Recommended Connection Method for Power and Communication Wiring (To minimize communication wiring ence)

Power Wiring:

The main power is supplied to the outdoor unit. The field supplied connecting cable from the outdoor unit to indoor unit consists of three (3) wires and provides the power for the indoor unit. Two wires are high voltage AC power and one is a ground wire.

Consult your local building codes and the NEC (National Electrical Code) or CEC (Canadian Electrical Code) for special requirements.

All wires must be sized per NEC or CEC 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.

Per caution note, only copper conductors with a minimum 300 volt rating and 2/64--inch thick insulation must be used.

Communication Wiring:

A separate shielded copper conductor only, with a minimum 300 volt rating and 2/64--inch thick insulation, must be used as the communication wire from the outdoor unit to the indoor unit.
