FFMA Base Series Fan Coil Sizes 018 thru 037

Product Data

The FFMA Series Fan Coil unit is primarily designed for apartment applications as an upflow only indoor fan coil for split--system heat pumps for use with Puron refrigerant. Accessory field--installed electric heat kits are available in 5, 7.5 or 10 kW sizes. The 018, 024, 030, and 036 size units use a piston refrigerant metering device. The 019, 025, 031 and 037 size units come equipped with a TXV. All unit sizes are factory--configured for Puron refrigerant. However, they can be used for R--22 applications with the addition of an accessory R--22 TXV kit.

This fan coil may be installed in a frame mount or wall hung applications. The cabinet sizes allow units to fit between standard stud spacings. No return--air ductwork is required if the application provides for return air in the front of the cabinet through a louvered closet door or optional louvered wall panel. This unit is field convertible to bottom return without the need for an additional accessory kit.

The cabinet exterior is made of galvanized sheet metal and is sealed to limit cabinet air leakage to 2% when tested at 1.0 inches of static pressure and 1.4% when tested at 0.5 inches of static pressure. The cabinet is fully insulated to meet applications in conditioned space. This unit is not approved for installation in unconditioned spaces.

The FFMA 018, 024, 030, and 036 sizes use a 3--speed PSC motor. The FFMA 019, 025, 031, and 037 sizes use a 5--speed multi--tap ECM motor for efficiency. Motors are suspended at three points on rubber grommets for quieter operation. Coils are tin--plated copper tube, aluminum fin.

Refrigerant lines and thermostat low voltage connections are made through the top while the high voltage connections are made from either the right, left or top side of the fan coil. Sweat--type refrigerant connections on both liquid and vapor lines make for swift, low--cost installation. All service access to the unit is conveniently located in the front.

Primary and secondary drain connections exit from the bottom or either side of the cabinet. Fresh air intake holes measuring 3.4” (35 mm) are located on each side of the unit cabinet and come capped from the factory.
