WARNING
The clean Air Act of 1990 bans the intentional venting of
refrigerant (CFCs, HCFCs, and HFCs) as of July, 1992.
Approved methods of recovery, recycling or reclaiming
must be followed. Fines and/or incarceration may be
levied for noncompliance.
CAUTION
As with any mechanical equipment, contact with sharp
sheet metal edges can result in personal injury. Take
care while handling this equipment and wear gloves
and protective clothing.
IMPORTANT
All illustrations in this instruction are typical and do
not always represent the exact appearance of the
equipment.
IMPORTANT
The compressor in this unit contains PVE
oil (Polyvinylether). PVE oil is formulated for
hydrofluorocarbon (HFC) refrigerants, such as HFC-
410A, which this system contains. While it may have
some miscibility properties with mineralbased oil and
POE oil (Polyolester), it is not recommended to mix PVE
oil with any other type of refrigerant oil.
