Figure 3-18. Priming Compressor (with Shell & Tube Oil Cooler) and Piping
Section 3 • Installation
NOTE
Oil separator does not need to be fi lled again until oil
level reaches Minimum Operating Level.
Every size of compressor will hold different amounts
of oil, so amount of oil draining back into oil
separator will vary.
21. More accurate fi ll levels can be accomplished by
marking the level on the oil separator (2) after cor-
rect levels have been achieved during the unit oper-
ation and when the compressor unit has been down
for 1 hour.
