WARNING
!
These units use r­410A refrigerant which operates at 50 to 70%
higher pressures than r­22. Use only r­410A 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
r­410A 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
SSC­APG011­en.
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.
