HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM PAGE:9/25 2.2 Prevent moisture from entering into the enclosed unit system. When the moisture entered into the unit, the refrigerant oil and the organic compound material presented in the hermetic motor will possibly decompose on the affecting of water . It will result in the capillary depositing and the reducing of insulation resistance.

HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM PAGE:10/25 Dry nitrogen should be charged in compressor before assembly of system. Welding should be finished within one minute after charge of nitrogen. Dry nitrogen needs to be charged again and weld if over one minute. Always purge the compressor with dry nitrogen during assembly of system .
