INTRODUCTION
FSA Fan Coils may be used for cooling or heat pump
operation, with or without electric heat. Models are
available with factory installed electric heaters (5 kW, 7.5
kW, or 11 kw) and with no heat. Installations without
electric heat require a Cooling Control Kit (accessory part
number AMWK001CK).
FEA and WAHA Fan Coils may be used for cooling or heat
pump operation, with or without electric heat. Models have
factory installed electric heaters (5 kW, 7.5 kW, or 11 kw).
FSA, FEA, and WAHA Fan Coils are designed to be
installed in an upflow position, free air return ONLY,
suitable for closet or flush-mount installations.
NOTE: Local codes may limit application of systems
without a ducted return to single story dwellings.
CHECK EQUIPMENT
Unpack Fan Coil and move to final location. Remove
carton, taking care not to damage Fan Coil. Inspect
equipment for damage prior to installation. File claim with
shipping company if shipment is damaged or incomplete.
LOCATION
Select the best position which suits the installation site
conditions. The location should provide adequate
structural support, space in the front of the unit for service
access, clearance for return air and supply duct
connections, space for refrigerant piping connections and
condensate drain line connections. If heaters are being
installed, make sure adequate clearance is maintained
from supply duct work. See "Clearances" in Figure 1.
All models have a factory installed and appropriately
sized hard shut-off TXV metering device for use with
R-22 (FSA2X) or R410A (FSA4X, FEA4X, WAHA)
refrigerant.
PRODUCT DAMAGE HAZARD
Failure to follow this caution may result in product
damage.
This Fan Coil has a hard shut-off TXV metering de-
vice. A compressor Hard Start Kit is REQUIRED in
all applications where the matching outdoor unit
has a single-phase reciprocating compressor.
Locate rating plate on Fan Coil. It contains information
needed to properly install Fan Coil. Check rating plate to
be sure Fan Coil matches job specifications.
If the Fan Coil is located in an area of high humidity,
nuisance sweating of casing may occur. On these
installations, a wrap of 2" (51mm) fiberglass insulation
with a vapor barrier is recommended.
An access panel is provided on the front of the cabinet for
simple access to blower assembly and electrical controls.
Minimum clearance of 21" (533mm) in front of access
panel is required for service.
INSTALLATION
Fan coil is designed for free-air return, such as enclosed
in a closet with Iouvered door or flush mounted in a wall.
Factory-authorized Iouvered grille kits are available for
flush mount applications (accessory part numbers
AMWK001WG and AMWK002WG).
In Closet
When Fan Coil is installed in a closet with a Iouvered door
in return-air path, the free area of Iouvered opening in the
door must be a minimum of 2.25ft 2 (0.2m2)• Either align
door opening with Fan Coil inlet or provide a 10" (254mm)
clearance between door and Fan Coil.
Flush Mount
If Fan Coil is to be flush mounted in a wall, provide
adequate support underneath base of unit. Make sure
Fan Coil is level or top tilting slightly forward to assure
proper condensate drainage.
Hanging Cabinet
Cabinet may by hung from the wall using accessory
brackets (accessory part number AMWK001MK).
Use 1"x4" or 2"x4" (25x102mm or 51x102mm) wood
piece across studs for support at top of cabinet and same
size wood for spacer at bottom of cabinet. Position
bottom spacer between cabinet and wall so that it holds
the Fan Coil out from the wall in a vertical position. Refer
to Figure 2.
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in proper-
ty damage
When hanging cabinet, both wall support and
spacer must be the same thickness or the unit will
not hang correctly and Condensate Water will not
drain correctly. Fan Coil must be vertical or top
tilted slightly forward (accessory bracket creates
slight tilt).
