Product Data AIRSTREAM™ 42BHC,BVC System Fan Coils 600 to 4000 Cfm Carrier’s versatile belted fan coil units satisfy design requirements: • A selection of 8 sizes covers capacities from 600 to 4000 cfm • Choice of motors, from 1/4 to 5 hp, eliminates oversizing • Wide range of coil options for 2-pipe or 4-pipe systems • Optional DX coils with expansion valve and distributor • Single and three-phase electric heat (1.
Fan wheels are designed to provide low operating costs The forward-curved, centrifugal, double-inlet fans are statically and dynamically balanced at the factory to minimize transmission of vibration to the building structure. The belt-driven motor (single or three phase) has a variable-pitch pulley which adjusts at the jobsite to accommodate limited ranges of air quantities and pressures.

Application data Basic definitions UNIT HAND Unit hand — When facing the supply air outlet from the front of the unit (air blowing in your face), your right hand will be the right hand side of the unit and your left hand the left hand side of the unit. PIPING COMPONENTS SYMBOL/SKETCH DESCRIPTION CV FACTOR 3/4 1/2 RATING* PSI F MANUAL AIR VENT: Threaded brass needle valve with screwdriver slot for adjustment.
Application data (cont) PIPING COMPONENTS (cont) SYMBOL/SKETCH DESCRIPTION BALANCE VALVE: Variable water flow manual balancing valve with screwdriver slot adjustment screw. Application — Often used in conjunction with test port fittings for water flow balancing. Balance by temperature differential or coil pressure drop (check specifications for service fittings required if balancing by pressure drop). May be used in 3-way valve bypass line to permit equal flow balancing.
PIPING COMPONENTS (cont) SYMBOL/SKETCH DESCRIPTION 2-WAY MOTORIZED VALVE: Electric 2-position flow control valve (open/closed). Normally closed body with manual override lever. Installed in supply line to unit. Application — All standard control and valve packages are based upon normally closed valves (valve electrically powered open and closed by spring return when electric power removed).
