—3— 1. PREF ACE This Service Manual provides various service information, containing the mechanical and electrical parts etc. This dehumidifier was manufactured and assembled under the strict quality control system. The refrigerant is charged at the factory.
— 4 — 1.4 SPECIFICA TIONS CAPACITY (Pint/Day) 30 40 50 POWER SUPPLY (Phase, V, Hz) 1 ø , 115V, 60Hz REFRIGERANT R134a R22 REFRIGERANT CHARGE, oz(g) 4.76(135) 5.11(145) 7.05(200) CONTROL, DEFROST THERMOSTAT HUMIDISTAT CONTROL RANGE : 20% ~ 80% RH NORMAL SETTING : 42 ± 5% RH COMPRESSOR MODEL NO.
1.6.1 HOW DOES THE DEHUMIDIFIER WORK? Moist, humid air is drawn over a cold refrigerated dehumidifying coil. Moisture in the air condenses on this coil and drains into a bucket (or through the bucket into a hose and drain).
1.6.5 HUMIDIST A T Humidistat controls constant relative humidity in the room automatically. When the relative humidity in the room increases to the selected level, the dehumidifier starts automatically. And the relative humidity drops to the selected level, the dehumidifier stops automatically.
