A. GENERAL
This information is intended for use by individuals posses-
sing adequate backgrounds of electrical and mechanical
experience. Any attempt to repair a central air conditioning
product may result in personal injury and or property

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
overafl 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 con-
tain 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 "hygro-
scopic" 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 dri-
ers when opening the system for component replacement.
For specific handling concerns with R-410A and POE oil, ref-
erence Retrofit Bulletin TRN-APGO2-EN.
Check for transportation damage after unit is uncra_d.
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.
