General Information
NOTICE
Compressor Damage!
POE oil is hygroscopic – it absorbs water directly
from the air. This water is nearly impossible to
remove from the compressor oil and can result in
compressor failures.
To prevent POE oil from absorbing water, the
system should not remain open for longer than
necessary. When open, dry nitrogen should flow
through the piping. Only new oil containers should
be used for service and maintenance. 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.
• Change the compressor oil; the contractor should
assist a qualified Trane Technician with this
responsibility
• Evacuate the chiller under 1000 microns; the contractor
should assist a qualified Trane Technician with this
responsibility
• Recharge the chiller with dry nitrogen to 5 psig; the
contractor should assist a qualified Trane Technician
with this responsibility
• Replace and/or repair insulation
• Reconnect electrical connections

• Spot paint the chiller if necessary
