Compressor Oil
Once all of the compressors have been started, verify
that the oil level is visible through the sight glass or
above the sight glass. Use appropriate lighting (flash
light) to verify the presence of oil. A tandem manifold
set may have different oil heights, but still must be
visible in the sight glass or above the sight glass.
After shutting the compressors off, check the oil’s
appearance. Discoloration of the oil indicates that an
abnormal condition has occurred. If the oil is dark,
overheating may have occurred. Potential causes of
overheating: compressor is operating at extremely
high condensing temperatures; high superheat; a
compressor mechanical failure; or, occurrence of a
