Safety Precautions

WARNINGS
UNIT CONTAINS R-410A REFRIGERANT!
R-410A OPERATING PRESSURE EXCEEDS
THE LIMIT OF R-22. PROPER SERVICE
EQUIPMENT IS REQUIRED. FAILURE TO USE
PROPER SERVICE TOOLS MAY RESULT IN
EQUIPMENT DAMAGE OR PERSONAL INJURY.
SERVICE
USE ONLY R-410A REFRIGERANT AND
APPROVED POE COMPRESSOR OIL.
These units use R410A 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
whenver 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 TRN-APG02-EN.
