Product Data FH4A Fan Unit Sizes 00 thru 004 Air Handling Technology At Its Finest Reliability, dependability, and great value are built into the FH4A 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 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, hasslefree hookup (003 and 004 when coupled with coil are upflow/downflow only). All models feature the components you need and expect. Every unit comes fully equipped with solid-state cooling controls and each terminal board is prewired to accept an electronic air cleaner. The FH4A, 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 30 kw, either fused or with a circuit breaker, or non-fused for 0 kw and less. Homeowners like the compact size and attractive finish of the units, and appreciate the low-maintenance, easyto-clean permanent filter in our multipoise units. There are plenty of reasons to choose the model FH4A fan unit just check the specifications. Copyright 996 Carrier Corporation Form FH4A-3PD

Not recommended for use above 0.60 in external static pressure. Airflows in this region have the potential for condensate to blow out of the drainpan. If usage in this region is desired, consult duct static pressure graph for allowable return and supply duct static pressures. Airflows in this region are outside recommended airflow for all applications. Usage at these airflows could result in condensate blowing out of the drainpan.

Evaporator Coil Kit The kit contains a heating/cooling coil and drain pan. SUGGESTED USE: Accessory coil used with FH4A fan unit. 2. Disconnect Kit The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely. SUGGESTED USE: FK4, FC4, FB4, FA4, and FH4 units for 3kw through 0kw electric resistance heaters and cooling controls. 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 FK4, FC4, FB4, FA4, and FH4 fan coils are used in downflow applications. 4. Downflow Base Kit This kit is designed to provide a 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 FK4, FC4, FB4, FA4, and FH4 fan coils are used in downflow applications. 5. Single Point Wiring Kit The single point wiring kit acts as a jumper between L 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: FK4, FC4, FB4, FA4, and FH4 fan coils only with 5kw and 20kw heaters. 6. Fan Coil Filter The kit consists of 2 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 the filters in FK4, FC4, FB4, FA4, and FH4 fan coils. 0
