The UC series fan coil is designed as an upflow indoor air handler for use with split-system heat pumps or condensing units.

First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor unit(s) and which expansion valves (if any) are required.
The UC can be installed on a closet platform, hung on a closet wall, or recessed in a wall between the studs. All models are 22" wide to allow standard stud spacing for all sizes.

The cabinet is made of galvanized steel and is fully insulated. The non-corrosive thermoplastic condensate pan is sloped to ensure proper drainage. For installation flexibility, drain piping can come from the bottom, front, left, or right side of the cabinet.

New Feature: - The removable door of the optional wall panel now includes "captive screws" that won't fall out when the door is removed for service or filter change.
