relative to the installation of these fan
coil units only. For other related
equipment refer to the proper instruc-
tions.
Material in this shipment has been
inspected at the factory and released

made immediately. Any evidence of
rough handling or apparent damage
should be noted on the delivery re-
ceipt and the material inspected in

FAN COIL UNIT
The installer must adhere strictly

and debris. The unit must not
be operated under any
circumstances without an air
filter in place.
to all local and national code require-
ments pertaining to the installation of
this equipment.
These units are designed for instal-
lation in a horizontal position.
The CDXQ is designed for free return
installation (non-ducted return air),
therefore the furred down area must
be completely sealed (except return
air grille) to ensure that all return air is
pulled from the conditioned space
and not from other areas of the build-
ing structure.
Access must be provided for servic-
ing the unit. If this access is provided
by a removable ceiling panel, ample
space must be allowed for removal of
the blower panel and to provide ac-
cess to electrical and plumbing con-
trols.
All CDXQ units are U.L. listed for
installation with zero inches clear-
ance to combustible materials. This
includes the unit cabinet, discharge
plenum and connecting ducts.
AIR DISTRIBUTION
DUCTS
All duct work must be installed in
accordance with National Fire Pro-
tection Association Codes 90A and
90B. Ducts should be adequately
insulated to prevent condensation
during the cooling cycle and to mini-
mize heat loss during the heating
cycle. All return air must be filtered to
prevent dirt buildup on the coil sur-
face. If there is no ducted return,
applicable installation codes may
limit the unit to installation only in a
single story residence. In many
cases it is acceptable to use ducting
of the same size as the fan coil
connections. However, unique ar-
rangements or long duct runs must be
confirmed by a local professional.
The manufacturer will not be respon-
sible for misapplied equipment.
ELECTRICAL
All wiring must comply with local
and national code requirements.
Units are provided with wiring dia-
grams and nameplate data to provide
information required for necessary
field wiring.
These units are provided with a
Class 2 transformer for 24-volt control
circuits. Should any add-on equip-

in damage to components

tion and the safety of the installer.
