START

Has refrigerant recovery work been done?

YES

Remove the defective compressor.

Mount a service compressor.

Leakage check

Vacuuming

Charge the refrigerant.

END

Turn off the leakage breaker.

NO

Open PMV forcedly and then recover refrigerant 
using a refrigerant recovery unit.

Never recover the refrigerant to the outdoor unit.

For the refrigerant recovery work during reinstallation 
of repair work, be sure to use the refrigerant recovery unit. 

Recovery of refrigerant to the outdoor unit is unavailable; 
otherwise a serious accident such as explosion or 

 injury 

may 

be 

caused.
