FEATURES / BENEFITS
AN INEXPENSIVE AND CREATIVE
SOLUTION TO DESIGN PROBLEMS.
The 38HDF(QRF) / 40KMC (KMQ) 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 in- -ceiling cassette fan coils are ideal for retrofit or
modernization projects where a false ceiling is available. This
selection of fan coils permits inexpensive and creative solutions to
design problems such as:
S
S
These compact in- -ceiling cassette units require less than 12 inches
(304.8 mm) of false ceiling space and the only part that is seen is
an aesthetically pleasing grille that blends with most decor.
Add- -ons to current space where the existing system
cannot handle the load.
Special space requirements. like a conference room,
where the load varies.
