The ideal compliment to your ducted system when it is impractical

or prohibitively expensive to use ductwork.

INDUSTRY LEADING

FEATURES / BENEFITS

AN INEXPENSIVE AND CREATIVE

SOLUTION TO DESIGN PROBLEMS.

The 38 HDF(QRF) / 40QNC (QNQ) series duct--free 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 inexpensive and 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.

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 BUILT--IN RELIABILITY When noise is a concern, the duct--free 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.

OUTDOOR UNIT ACCESSORIES Low Ambient Kit Stacking Kit The kit controls condenser fan cycling using a pressure switch. It is specifically designed to cycle the outdoor fan--motor in response to saturated condensing pressure. This device maintains a constant saturated condensing temperature of 100 _F ± 10 _F (37.78_C ± 6.5 _C) at outdoor--air temperatures between 55 _F and --20 _F (12.78_C ± --12.22_C), and can be used on all outdoor units without changing the outdoor fan motor.

APPLICATION DATA UNIT SELECTION SYSTEMS OPERATING CONDITIONS The horizontal units are available as cooling only and heat pumps. For most applications, the cooling load dictates the size selection. Select equipment to either match or be slightly less than anticipated peak load. This provides better humidity control, fewer unit cycles, and better low load performance.

General refrigerant line sizing: 1. Piping for indoor unit can be routed in the direction shown in Fig. 12. A08358A Fig. 12 – Indoor Unit Piping Configurations 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.
