- Page 10 HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM PAGE:8/30 9 Oil back and oil level The oil should be returned continuously to the compressor and the structure of the refrigerating system should not make oil stay in the system. The oil level in compressor should be higher than 7.5 mm from the lubricating piece fixed on the end of the crankshaft.If not keep the oil level, the shortage will occur, and influence the reliability of the compressor.(please check the oil level in the compressor with the sight glass which supplied form SHEC.
- Page 11 HEAT PUMP WATER HEATER COMPRESSOR CRITERIA FOR LONG LIFE SYSTEM PAGE:9/30 15 Impurities in refrigerating system (1) The weight of residue on the inside surface of the heat exchanger and tube should be less than 0.01g/m . But metallic dust should not be permitted in the system. This value means the weight of foreign residue collected by filer paper after washing inside surface of the heat exchanger tubes with R-11.
