[ 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.
