Reliability, dependability, and great value are built into the FH4B
Fan Units. The unit is compact and easy to install, with capacities
ranging from 800 to 2000 CFM. The units are the right choice if
you need versatility and affordability in a fan unit.
These fan coil units offer an air handler for practical, no-nonsense application and outstanding performance. The multipoise
units allow greater flexibility to meet your upflow, downflow, or
horizontal installation requirements, and offer multiple electric
entry to permit quick, hassle-free hookup (003 and 004 when
coupled with coil are upflow/downflow only). All models come
fully equipped with solid-state cooling controls.
The FH4B, with its 3-speed motor and field-installed heater
package, provides the application versatility required for most
installations. Heater packages are available from 3- through 30kw, either fused or with a circuit breaker, or non-fused for 10-kw
and less.

NOTES: 1. Airflow based upon dry coil at 230v with factory approved accessory filter and electric heater (10-kw electric heat, sizes 001 and 002;
15-kw electric heat, sizes 003 and 004).
2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
—Return static pressure must be less than 0.4 in. wc
—Horizontal applications of 048-070 sizes must have supply static greater than 0.20 in. wc
Airflow outside max ARI airflow of 450 cfm/ton on 018-154 sizes
Airflow above 400 cfm/ton on 060-070 sizes. Airflows in this region could result in condensate blowing off coil or splashing out of drain pan.
† KFAEH2501N09 is field convertible to 3 phase.
‡ Single point wiring kit required for these heaters in Canada.
** Blower motor heat not included.
When using units with 20-, 24-, and 30-kw electric heaters, maintain a 1-in. clearance from combustible materials to discharge plenum and ductwork,
and maintain a distance of 36 in. 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.
2. For fan coil sizes 042-060 and all FK4D, FV4B sizes.
3. Single circuit application of F15 and F20 heaters requires single-point wiring kit accessory
† Field convertible to 1 phase, single or multiple supply circuit.
(ANSI/NFPA 70).
‡ Field convertible to 3 phase.
** Includes blower motor amps of largest fan coil used with heater.
†† Copper wire must be used. If other than uncoated (non-plated), 75°C ambient, copper wire (solid wire for 10 AWG and smaller, stranded wire for larger than 10 AWG) is used, consult applicable tables of the National Electric Code
‡‡ Length shown is as measured 1 way along wire path between unit and service panel for a voltage drop not to exceed 2%.
NOTES:
*** Heaters are Intelligent Heat capable when used with the FK, FV fan coils and corporate 2-speed programmable thermostat (TSTATBBP2S01-A), or Thermidistat™ Control (TSTATBBPRH01-B).
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.

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.
