  • Page 6 [ 1] Cautions for serv ice (1) Perform serv ice after collecting th e refrigerant left in unit completely. (2) Do not release refrigerant in th e air. (3) After completing serv ice, ch arge th e cycle with specified amount of refrigerant. (4) Wh en performing serv ice, install a filter d rier simultaneously.
  • Page 7 2Dimensions of flare cutting and flare nut The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that, R410A is a refrigerant, which has higher risk of leakage because of its working pressure higher than that of other refriger- ants.
