Product Data
AIR HANDLER TECHNOLOGY
AT ITS FINEST
The FX4D fan coils combine the proven technology of Carrier fan
coil units with Puron, the environmentally sound refrigerant.
These fan coils are loaded with popular features. Factory--installed,
refrigerant--specific thermostatic expansion valves (TXV) are
standard with these fan coil designs. The designs feature contoured
condensate pans with rugged, drain connections, ensuring that little
water is left in the unit at the end of the cooling duty cycle. The
lack of standing condensate and corrosion free pans improves IAQ
and product life, features homeowners appreciate.
Standard features include grooved copper tubing and louvered
aluminum fins. The large face areas of the refrigerant coils provide
superior efficiency for high SEER and HSPF performance. Coil
circuiting has also been updated to make the most of all Carrier
heat pumps and air conditioners. Also units come with solid state
fan controls, 1--in (25mm) thick insulation with R--value of 4.2,
multi--speed motors, and fully--wettable coils. Units can
accommodate factory-- and/or field--installed heaters from 3 to 30
kW.
It also should be noted that the unique cabinet design of these fan
coils meet new stringent regulations for cabinet air leakage -- a
requirement of 2% cabinet leakage rate when tested at 1.0 inches of
static pressure.
The FX4D fan coil is the Puron refrigeration design loaded with
popular features. It comes in a pre--painted (taupe metallic)
galvanized steel casing and is shipped with a cleanable, permanent
framed filter, and a factory--supplied power plug. ArmorCoatt
provides a tin plating of the indoor coil’s copper hairpins. This
creates a barrier between the corrosion--causing elements and the
coil. These fan coils utilize the latest in electronic commutation
motor (ECM) technology through the use of high efficiency, X13,
blower motors.

--- Airflow outside 450 cfm/ton.
NOTES:
1. Airflow based upon dry coil at 230v with factory--approved filter and electric heater (2 element heater sizes 018 through 037, 3 element
heater sizes 043 through 061).
2. Airflow at 208 volts is approximately the same as 230 volts because the X--13 motor is a constant torque motor. The torque doesn’t drop
off at the speeds the motor operates.
3. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
Return static pressure must be less than 0.40 in wc.
Horizontal applications of 043 -- 061 sizes must have supply static greater than 0.20 in wc.
4. Airflow above 400 cfm/ton on 049--061 size could result in condensate blowing off coil or splashing out of drain pan.

QTY/SIZE
When using units with 20--, 24--, and 30--kW electric heaters, maintain a 1--in. (25 mm) clearance from combustible materials to discharge
plenum and ductwork and maintain a distance of 36 in. (914mm) from the unit. Use an accessory downflow base to maintain proper clearance
on downflow installations. Use flexible connectors between ductwork and unit to prevent transmission of vibration. When electric heater is
installed, use heat resistant material for flexible connector between ductwork and unit at discharge connection. Ductwork passing through
unconditioned space must be insulated and covered with vapor barrier

ACCESSORY KITS DESCRIPTION SUGGESTED AND REQUIRED USE
1. Disconnect Kit
The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely.
SUGGESTED USE: Units for 3-- through 10--kW electric resistance heaters and cooling controls.
2. Downflow Base Kit
This kit is designed to provide a 1--in. minimum clearance between unit discharge plenum, ductwork, and combustible materials. It
also provides a gap--free seal with the floor.
REQUIRED USE: This kit must be used whenever fan coils are used in downflow applications.
3. Downflow Conversion Kit
Fan coils are shipped from the factory for upflow or horizontal--left applications. Downflow conversion kits provide proper condensate
water drainage and support for the coil when used in downflow applications. Separate kits are available for slope coils and A--coils.
REQUIRED USE: This kit must be used whenever fan coils are used in downflow applications.
4. Downflow/Horizontal Conversion Gasket Kit
This kit provides the proper gasketing of units when applied in either a downflow or horizontal application.
REQUIRED USE: Fan coils in either downflow or horizontal applications.
5. Horizontal Applications -- Water Management Kit
This kit provides proper installation of fan coils under conditions of high static pressure and high relative humidity.
SUGGESTED USE: All fan coils.
6. Single Point Wiring Kit
FX4D
The single point wiring kit acts as a jumper between L1 and L3 lugs, and between the L2 and L4 lugs. This allows the installer to run
two heavy--gauge, high--voltage wires into the fan coil rather than 4 light--gauge, high--voltage wires.
SUGGESTED USE: Fan coils with 15-- and 20--kW fused heaters only.
7. Filter Kit (12 pack)
The kit consists of 12 fan coil framed filters. These filters collect large dust particles from the return air entering the fan coil and
prevents them from collecting on the coil. This process helps to keep the coil clean, which increases heat transfer and, in turn, the
efficiency of the system.
SUGGESTED USE: To replace filters in fan coils.
REQUIRED USE: All units unless a filter grille is used.
8. Fan Coil Filter Cabinet
This cabinet is mounted to the fan coil on the return air end and designed to slip over the outer fan coil casing. The cabinets are
insulated using the same insulation as production fan coils. They are designed for the removal of particulates from indoor air using
FILXXFNC00(14, 17, 21, 24) media filter cartridges. These fan coil media filter cartridge kits are designed for the removal of particles
from indoor air. The cartridge is installed in the return air duct next to the air handler or further upstream.
SUGGESTED USE: All fan coils.
9. Condensate Drain Trap Kit
This kit consists of 50 PVC condensate traps. Each trap is pre--formed and ready for field installation. This deep trap helps the system
make and hold proper condensate flow even during blower initiation.
SUGGESTED USE: All fan coils.
10. Air Cleaner 240--volt Conversion Kit
The AIRA electronic air cleaner comes ready for 115--v operation.
REQUIRED USE: This kit is required when running 240--volt circuit to air cleaner.
