3. Oil amount and type is also printed on the nameplate.
4. Use only Trane-approved oils and do not mix oils.
Oil Handling
POE oil is very hydroscopic, which means it absorbs
moisture very readily. Therefore, it is important to properly
handle the oil.
POE Oil handling guidelines
•
Always use the smallest container size required for the
job requirements.
•
Always leave the oil container tightly sealed until time
of use.
•
Do not reuse oil that has been opened.

Oil Level
Figure 1.
Compressor oil label
The oil should be visible through the oil sightglass both
during operation and when the compressor(s) is off. Oil
level slightly below the sightglass, but still visible is
acceptable.
Single compressor.
The oil level should be stable in the
sightglass.
Tandem and trio compressors.
•
Operation
—
The oil level will vary depending on the
operating condition.
•
Unloaded condition
have a higher oil level than the off compressor(s).
•
Loaded condition
—
Oil should be visible through all
of the compressor sight glasses. Some may have a
higher level than others, but this is not abnormal.
•
Off
—
After several minutes, the oil levels should be the
same in each compressor and should be visible in the
sightglass. This is the best method to determine if the
system has sufficient oil.
Units overcharged with oil will operate with degraded
performance and could lead to compressor damage.
Operating Envelope
The compressor must be operated within the published
operating envelope.
