ant 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 open-
ing 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.
