AH/AY-X08CR AH/AY-X10CR AH/AY-X13CR 1. Outline 1. 1 Refrigerant R410A (1) Adoption of R410A in Air Conditioners In 1974, it was pointed out that ozone layer in the upper stratosphere (about 20 ~ 40 km above ground) might have been damaged by the ozone depleting substances such as CFC (chlorofluorocarbon) and HCFC (hydrochlorofluorocarbon).
Page 39: Refrigerant R410A
AH/AY-X08CR AH/AY-X10CR AH/AY-X13CR (3) Lubricationg Oils for R410A As the lubricating oils for R22, mineral oils, alkylbenze synthetic oils, etc. have so far been used. As R410A features less solubility with these conventional lubricating oils such as mineral oils, the lubricating oils tend to stay within the refrigeration cycle.

AH/AY-X08CR AH/AY-X10CR AH/AY-X13CR 2.2 Processing of Piping Materials When performing the refrigerant piping installation, care should be taken to ensure that water or dust does not enter the pipe interior, that no other oil other than lubricating oils used in the installed air conditioner is used, and that refrigerant does not leak.
