INTRODUCTION
Model 40FKA Fan Coil units are designed for flexibility and can
be used for upflow, horizontal, or downflow (kit required and
manufactured and mobile home) applications. A Carrier Thermi-
distat™ Control (TSTATCCPRH01–B) is included with the
40FKA unit. See Back Page for QUICK REFERENCE COM-
FORT HEAT SET-UP INSTRUCTIONS.
These units are available for application in systems of 18,000
through 60,000 Btuh nominal cooling capacities. Factory-
authorized, field-installed electric heater packages are available in
5 through 30 kw. See Product Data for available accessory kits.
Before installing or servicing unit, always turn off all power
to unit. There may be more than 1 disconnect switch. Turn off
accessory heater power if applicable. Electrical shock can
cause personal injury or death.
INSTALLATION
Step 1—Check Equipment
Unpack unit and move to final location. Remove carton taking care
not to damage unit.
Inspect equipment for damage prior to installation. File claim with
shipping company if shipment is damaged or incomplete. Locate
unit rating plate which contains proper installation information.
Check rating plate to be sure unit matches job specifications.
Step 2—Mount Fan Coil
Unit can stand or lie on floor, or hang from ceiling or wall. Allow
space for wiring, piping, and servicing unit.
IMPORTANT:
When unit is installed over a finished ceiling
and/or living area, building codes may require a field-supplied
secondary condensate pan to be installed under the entire unit.
Some localities may allow the alterative of running a separate,
secondary condensate line. Consult local codes for additional
restrictions or precautions.
When installing any fan coil over a finished ceiling and/or living
area, installation of a secondary drain pan under entire unit to
avoid damage to ceiling is recommended.
40FKA Fan Coils can be installed for upflow and horizontal-left
applications as factory shipped. (See Fig. 2, 4 and 8.) Units can be
installed for horizontal-right applications with field modifications.
(See Fig. 5.) Units may be converted for downflow applications
using factory-authorized accessory kit.
NOTE:
To ensure proper drainage for horizontal installations,
unit must be installed so it is within 1/8 in. level of the length and
width of unit.
UPFLOW INSTALLATION
If return air is to be ducted, install duct flush with floor. Set unit
on floor over opening.
Only use return-air opening provided. All return air must pass
through the coil. (See Fig. 2.)
MODULAR UNITS
The 40FKA Fan Coil in size 006 is a 2-piece modular unit.
Modular construction allows installer to disassemble unit into 2
components, coil box and blower box, for ease of installation. (See
Fig. 3.)
To disassemble unit, remove rear corner brackets by removing 2
screws which secure brackets. (See Fig. 3.) Remove either 2
screws in each front corner of coil box, or 2 screws in blower box.
Do not remove all 4 screws in each corner. (See Fig. 3.) Sections
may now be separated by lifting top section from lower section.
To reassemble, reverse above procedure. Be certain to reinstall all
fasteners when reassembling.
HORIZONTAL INSTALLATIONS
Be sure installation complies with all applicable building codes
that may require installation of a secondary condensate pan.
