Fujitsu FH4821TPSASN 1-Stage Standard Efficiency 95% Non-Communicating Air Handler
The most compact unit design available, all standard heat airhandler models only 421/2 to 57"es [1079 to 1448 mm] high. Attractive pre-painted cabinet exterior. Rugged wall steel cabinet construction, designed for added strength and versatility. 1.0" foil faced insulation mechanically retained in blower compartment for excellent thermal and sound performance. Four leg blower motor mount. Blower housing with controls, motor and blower. Slide out design for service and maintenance convenience. Traditional open wire element design for heat applications. Field convertible for vertical downflow, horizontal left hand or right hand air supply. 3 combustible floor base accessories fit all model sizes when required for downflow installations on combustible floors. Indoor coil design provides low air side pressure drop, high performance and extremely compact size. Expansion valve on indoor coil provides for operation with air conditioning or heat pump using the same coil. Coils are constructed of aluminum fins bonded to internally grooved aluminum tubing. Coils are tested at the factory with an extensive refrigerant leak check.Coils have copper sweat refrigerant connections.Coils utilize chatleff metering device connections. Molded polymer corrosion resistant condensate drain pan is provided on all indoor coils. Supply duct flanges provided as standard on air handler cabinet. Provisions for field electrical, connections available from either side or top of the air handler cabinet. Connection point for high voltage wiring is inside the air handler cabinet. Low voltage connection is made on the outside of the air handler cabinet. Concentric knockouts are provided for power connection to cabinet. Installer may pull desired hole size up to 2"es [51 mm] for 11/2" [38 mm] conduit. Front refrigerant and drain connections
