The FF1E Series Fan Coil unit is primarily designed for apartment applications as upflow indoor air handlers for split-system heat pumps and air conditioners for use with Puron® refrigerant. These units are available with factory-installed electric heaters, which includes the disconnect. A field-installed cooling control with disconnect is also available for unit sizes 18, 24, 30 and 36 only. A Time Delay Relay (TDR) is included with either the electric heat or the cooling control packages.
This fan coil may be installed free-standing, wall hung or flush mounted in the wall. The 22-in (559 mm) wide cabinet size in all models allows units to fit between standard stud spacing. No return-air ductwork is required if the application provides for return air in the front of the cabinet through either a louvered closet door or an optional accessory decorative grille panel.
The cabinet exterior is made of pre-painted, galvanized sheet metal. The cabinet is fully insulated to meet applications in conditioned space. Additional insulation is required if the unit is installed in an unconditioned space. The unit is supplied with a replaceable filter.
Multi- speed, direct-drive, PSC blower motors have been selected to provide the proper air handling for both heating and cooling. Electronic commutating motors (ECM) use X13 high-efficiency motors to increase system performance. Motors are suspended at three points on rubber grommets for quieter operation.
All refrigerant lines, electrical power, and thermostat wiring enter from the top of the cabinet. Sweat- type refrigerant connections on both liquid and suction lines make for swift, low- cost installation. All service access to the unit is conveniently located in the front. All units come with a factory-supplied, hard- shutoff thermostatic expansion valve (TXV) metering device for performance improvement.
The drain pan is constructed of high-impact, sound-deadening, corrosion-proof polyester resin. Primary and secondary drain connections exit from the bottom or either side of the cabinet.
