The FPM(A,B) Series Fan Coil unit is primarily designed for multi-family applications as a horizontal only indoor fan coil for split-system heat pumps for use with Puron® refrigerant. The FPM(A,B) series fan coil is available in cased or uncased versions from the factory. Accessory field-installed electric heat kits are available in 3, 5, 6, 7.5 or 10 kW sizes. The electric heat, however, cannot be run simultaneously with refrigerant heat. The factory electric heat kits for the FPM(A,B) come with a control to prevent both electric heat and heat-pump heat from operating simultaneously.
The FPMA comes with a piston refrigerant metering device. The FPMB comes with a factory installed Puron TXV. These fan coils come configured for Puron refrigerant. However, they can be used for R-22 applications with the addition of an R-22 TXV kit.
The uncased version can be installed in a furred-in ceiling or in a field fabricated casing or duct. The cased version can be installed in a furred-in ceiling or with ducted return. Return air must be pass through a filter in all applications. Local codes may limit free-air-return type installations to single-level applications.
A louvered return air panel, which is sized for unit access and accepts either 1-in. or 2-in. air filters, is available as an accessory.
A solid access panel also is available.
Please note that when using the cased model, FPM(A,B)NC, in horizontal return applications, a bottom cover will need to be field fabricated.
Designated mounting locations are provided on the equipment. The factory cased version is fully insulated to meet applications in conditioned space. It also should be noted that the unique cabinet design of the cased coil meets the requirement of 2% cabinet leakage rate when tested at 1.0-in. of static pressure. This unit is not approved for installation in unconditioned spaces.
PSC blower motors have been selected to provide the proper air handling for both heating and cooling.
Refrigerant line connections are made on the side of the unit while the high and low voltage connections are made from either the right or left side of the fan coil. Sweat-type refrigerant connections on both liquid and vapor lines make for swift, low-cost installation. On cased units, the refrigerant lines can be run out the back or side of the unit while electrical connections can be run out either side or back of the casing.
Primary and secondary drain connections exit from the back or side of the cabinet.STANDARD FEATURESEnvironmentally-Sound Refrigerant Technology
