They are available with factory- or field-installed electric heaters both of which include the disconnect. A field- installed cooling control with disconnect is also available. A TDR (Time Delay Relay) is included with either the electric heat or the cooling control packages. The FF1DNE models are available with a factory installed TXV. This fan coil may be installed free standing, wall hung or flush mounted in the wall. The 22-in. wide cabinet size in all models allows 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 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. Unit is supplied with replaceable filter. Multispeed direct-drive PSC blower motors have been selected to provide the proper air handling for both heating and cooling. Motors are suspended at 3 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. The CHECK-FLO-RATER® piston ensures efficient and dependable refrigerant metering, and eliminates potential service requirements of other metering devices. The CHECK-FLORATER ® is located inside the unit, easily accessible for piston maintenance or changeout. In addition, units can be factory ordered with a hard shut-off 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.
