[2] Piping Machining

Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections.

Use only the necessary minimum quantity of oil !

Reason :

1. The refrigerator oil used for the equipment is highly hygroscopic and may introduce water inside.

Notes :

• Introducing a great quantity of mineral oil into the refrigerant circuit may also cause a compressor failure.

• Do not use oils other than ester oil, ether oil or alkylbenzene.
