relative to the installation of UC fan coil
units only. For other related equipment
refer to the proper instructions.

spected at the factory and released to the
transportation agency in good condition.
When received, a visual inspection of all
cartons should be made immediately.

FAN COIL UNIT
The installer must adhere strictly to all
local and national code requirements
pertaining to the installation of this equip-
ment.
These units are designed to be in-
stalled vertically in the upflow position by
the following mounting means:
Hung on closet wall
Using mounting kit 90PK3, air handler
may be wall mounted. Brackets and
screws are provided for the air handler.
It is recommended that sound isolating
material be installed to prevent any un-
desired transfer of sound.
Recessed in a wall
Installation of the fan coil recessed into
a partition wall with it's recommended
framing is shown in figure 1. This appli-
cation requires the optional louvered wall
panel which must be ordered from First
Co. Wall panel with frame is secured to
the studs by screws or nails after the dry
wall has been installed. Refer to figure 2
and 3.
Closet Platform Front Return
Fan coil is to be set on a platform and
secured by screws or nails. Sufficient
space for drain piping is required under
the platform.
****** WARNING ******
Extreme caution must be
taken that no internal damage
will result if screws or holes
are drilled into the cabinet.
****** WARNING ******
Unit must not be operated
during building construction
due to excessive airborne
dust and debris. The unit
must not be operated under
any circumstances without
an air filter in place.
AIR DISTRIBUTION
DUCTS
All duct work must be installed in accor-
dance with National Fire Protection As-
sociation Codes 90A and 90B. Ducts
should be adequately insulated to pre-
vent condensation during the cooling
cycle and to minimize heat loss during
the heating cycle. All return air must be
filtered to prevent dirt buildup on the coil
surface. 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. How-
ever, unique arrangements or long duct
runs must be confirmed by a local profes-
sional. The manufacturer will not be
responsible for misapplied equipment.
All fan coil units are U.L. Listed for
installation with zero inches clearance to
combustible materials. This includes the
fan coil cabinet, discharge plenum and
connecting ducts. Sufficient clearance
must be provided at the front of the fan
coil to allow access to electrical controls
and removal of the motor /blower assem-
bly for servicing. This clearance distance
should be approximately the same as the
depth dimension of the fan coil unit.
