COMPRESSOR LUBRICANT
-
Compressors with R410a refrigerant use synthetic polyester oil, each manufacturer using a
specific oil for his product.
-
The system must not remain open to the atmosphere more than 15 minutes.
-
Due to its hygroscopic qualities, you must be very careful during manipulation: when synthetic
oils mix up with mineral oil, they deteriorate causing obstructions and even the breakdown of
the compressor. Do not mix them under any circumstance.
