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 Add--ons to current space where the existing system
cannot handle the load.
S Special space requirements. like a conference room,
where the load varies.
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.
