40QAC / 38HDR
40QAQ / 38QRR
Ceiling---S uspended D u ct Fr ee S plit System
Sizes 018 to 060
the environmentally sound refrigerant
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 38HDR(QRR)/40QAC(QAQ) 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 ceiling--suspended fan coils are ideal for retrofit and
modernization projects where it is impractical or prohibitively
expensive to run ductwork and where there are no false ceilings or
wall space available. This selection of fan coils permits
inexpensive and creative solutions to design problems such as:
S Special space requirements such as garages.
S When changes in the load cannot be handled by the
existing system like restaurants.
S When adding air conditioning to spaces that are heated
by hydronic or electric heat and have no ductwork like
schools.
S Historical renovations or any application where
preserving the look of the original structure is essential
like churches.
These compact indoor fan coil units blend nicely with most
ceilings and protrude less than 10 inches (254 mm) from the
ceiling. Advanced system components incorporate innovative
technology to provide reliable cooling performance at low sound
levels.
