12 Accessory Kits Description Suggested and Required Use. Disconnect Kit The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely. SUGGESTED USE: FC4, FB4, and FA4 units for 3kw through 0kw electric resistance heaters and cooling controls. 2. 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 FC4, FB4, and FA4 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 FC4, FB4, and FA4 fan coils are used in downflow applications. 4. 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, highvoltage wires into the fan coil rather than 4 light-gage, high-voltage wires. SUGGESTED USE: FC4, FB4, and FA4 fan coils only with 5kw and 20kw heaters. 5. 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 filters in FC4, FB4, and FA4 fan coils. REQUIRED USE: All FA4A units unless a filter grille is used. 6. Power Plug Kit The kit consists of 25 wire harness assemblies. Each plug provides the high-voltage power connection to the fan coil in the absence of electric heat. REQUIRED USE: FA4A units installed without electric heat.

When using units with 20-, 24-, and 30-kw electric heaters, maintain a -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.
