ELECTRIC HEATER STATIC PRESSURE DROP
The airflow performance data was developed using fan coils with 10-kw electric heaters (2 elements) in the 001 and 002 size units and
15-kw heaters (3 elements) in the 003 and 004 size units.

The airflow performance data was developed using fan coils with 10-kw electric heaters (2 elements) in the 001 and 002 units and 15-kw heaters
(3 elements) in the 003 and 004 units. For fan coils with heaters of a different number of elements, the available external static at a given CFM from the
curve may be corrected by adding or subtracting available external static pressure as indicated above.
ACCESSORIES
* Factory authorized and listed, field-installed.
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: FH4 units for 3-kw 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 FH4 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 FH4A fan coils are used in downflow applications.
4. Single Point Wiring Kit
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 2 heavy-gage,
high-voltage wires into the fan coil rather than 4 light-gage, high-voltage wires.
SUGGESTED USE: FH4 fan coils with 15-kw and 20-kw fused heaters only.
5. Fan Coil Filter
The kit consists of 12 fan coil framed filters. These filters collect large dust particles from the return air entering the fan coil and prevent 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 FH4 fan coils.
6. Evaporator Coil Kit
The kit contains a heating/cooling coil and drain pan.
SUGGESTED USE: Accessory coil used with FH4 fan unit.
7. Downflow/Horizontal Conversion Gasket Kit
This kit provides the proper gasketing of units when applied in either a Downflow or Horizontal application.
REQUIRED USE:
FH4 fan coils.
