Compressor Oils
Check to see that the oil level is 1/8 to 1/3 up on the compressor sight glass on compressors so equipped
before starting the compressor and after 15 to 20 minutes of operation.
CAUTION: Oil levels should not be allowed to go above the centre or 1/2 of the sight glass. Excessive oil levels
in the compressor can result in excessive compressor noise, higher power consumption or internal compressor
damage.
Welded hermetic compressors normally do not have sight glasses or means of determining their oil level. This
type of compressor is usually installed in packaged systems or in close proximity to the fixture.
All welded hermetic compressors are factory charged with enough oil to compensate for any piping losses up to
about 35 ft (10.7 m) (one way) remote location. In the event of any substantial oil loss due to a leak or excessive
line run, recharge as per the table below.
Add approximately 1/3 fl oz per foot (32 ml per meter) for any remote location over 35 ft (10.7 m). If in doubt of
an actual oil level, the only positive check is to remove the compressor and drain the oil (through the suction
connection) and recharge with the correct factory charge (refer to unit specifications). DO NOT
re-use drained
oil that has been exposed to the atmosphere. DO NOT re-fill, at any one time more than a total of 110 % of the
compressor’s factory specified charge. Allow time for some of the oil to circulate into the system.
