A. GENERAL
This information is intended for use by individuals pos ses-
s ing adequate backgrounds of electrical and mechanical

NOTICE:
Trane has always recommended installing Trane
approved matched indoor and outdoor systems.
The benefits of installing approved matched systems
are maximum efficiency, optimum performance and
best overall system reliability.
These units use R-410A refrigerant which operates at 50 to 70%
higher pressures than R-22. Use only R-410A approved service
equipment. Refrigerant cylinders are painted a “Rose” color to
indicate the type of refrigerant and may contain a “dip” tube to
allow for charging of liquid refrigerant into the system. All R-410A
systems use a POE oil that readily absorbs moisture from the
atmosphere. To limit this “hygroscopic” action, the system should
remain sealed whenever possible. If a system has been open to
the atmosphere for more than 4 hours, the compressor oil must
be replaced. Never break a vacuum with air and always change
the driers when opening the system for component replacement.
For specific handling concerns with R-410A and POE oil,
reference Retrofit Bulletin
SSC-APG011-EN.
Check for transportation damage after unit is uncrated.
Report promptly, to the carrier, any damage found to the
unit.
To determine the electrical power requirements of the unit,
refer to the nameplate of the unit. The electrical power
available must agree with that listed on the nameplate.
