Specifications are subject to change without notice.
A. UPFLOW INSTALLATION
If return air is to be ducted through a floor, set unit on floor
over opening and use 1/8 to 1/4 inch thick (3 to 6 mm thick)
fireproof resilient gasket between duct, unit, and floor.
Side return is a field option on slope coil models. Cut opening
per dimensions shown in Figure 2. A field−supplied bottom
closure is required.

B. MODULAR UNITS
FEM4X6000B, REM4X6000B, and FXM4X4800/6000 fan
coils are two−piece modular units. This allows for modular
units to be disassembled and components moved separately
to installation area for reassembly. This process
accommodates small scuttle holes and limiting entrances to
installation sites (Figure 1).
