INDUSTRY LEADING FEATURES /

BENEFITS

A PERFECT BALANCE BETWEEN BUDGET

LIMITS, ENERGY SAVINGS AND COMFORT.

The 38MHRCQ series ductless systems are a matched combination

of an outdoor condensing unit and an indoor fan coil unit connected

only by refrigerant tubing and wires.

The ductless system 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.

APPLICATION DATA Unit Selection Metering Devices Select equipment that either matches or supports slightly more than the anticipated peak load. This provides better humidity control, fewer unit cycles, and less part-load operation. The outdoor unit utilizes a capillary tube to manage the connected fan coil’s refrigerant flow. For units used in spaces with high sensible loads, base equipment selection on unit sensible load, not on total anticipated load.
PAGE 16
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.
