†Net oil pressure = oil pressure gage reading – suction pressure. The
above oil pressure is typical with mineral or alkylbenzene oils. A slight
increase in oil pressure may result with the use of PolyolEster (POE) oil.

Summary
2 OPEN-DRIVE COMPRESSORS These compressors are designed to operate with Refriger- ants 12, 22, 134a, 502, or 507/404A. See Table 1. Operating Requirements — Satisfactory operation of a reciprocating compressor depends on 3 fundamentalrequirements: 1. Prevention of excess discharge temperature.2. Ade...
4 Compressor Capacity Notes 1. Compressor capacities are based on 1750 rpm and 15 F subcooling for all unit sizes and refrigerants. 2. Multiplying factors for other rpm: See Multiplying Factors chart on page 31. 3. Liquid subcooling greater than (less than) 15 F incorpo- rated in ratings increases (...
