IMPORTANT
If this unit is being matched with an approved line set
or indoor unit coil that was previously charged with
mineral oil, or if it is being matched with a coil which
was manufactured before January of 1999, the coil and
empty all existing traps. Polyvinyl ether (PVE) and polyol
ester (POE) oils are used in GE Appliances variable-
capacity units charged with HFC-410A refrigerant.
Residual mineral oil can act as an insulator, preventing
proper heat transfer. It can also clog the expansion
device and reduce system performance and capacity.

contaminants (i.e., compressor burn out).
Polyvinyl ether (PVE) oil is used in the NS23A24M, 36M,
and 48M with rotary compressors. For installations of the
NS23A24M, 36M, and 48M units with refrigerant lines or
coils previously charged with R410A and POE oil, GE

be in the system. The NS23A60M air conditioners have
variable capacity scroll compressors that use POE oil.
