15. REFRIGERANT RECOVERY
[Working procedure]
1.Recovery retaining oil in existing gas pipe Approx. 1 min
Close gas stop valve (liquid stop valve: open)
and recovery refrigerant from gas stop valve port.(Fig.1)
2.Recovery retaining oil in existing liquid pipe Approx.1 min
Recovery refrigerant from liquid stop valve port.(Fig.2)
3.Recovery refrigerant in outdoor unit Approx 2-3 min
Recovery refrigerant from outdoor unit refrigerant recovery port *1• (Fig.3)
NOTE M*1 Can be omit this procedure if there has no refrigerant recovery port.
4.Recovery refrigerant in accordance with Fluorocarbons Recovery
and Destruction Law
If refrigerant recovery port "2 pressure became lower than gas stop valve
port pressure, refrigerant will recover at the simultaneous from the gas
stop valve port, open gas stop valve (Fig.3-G)) gradually to avoid from
pressure rising rapidly. (Fig.3-Q))
NOTE MM*2 Recovery refrigerant from liquid valve port and stop valve port
simultaneous if there has no refrigerant recovery port.
Retaining oil recovery amount improved
approx. 5 times from regular refrigerant
recovery method
(pipe length, height difference, pipe path etc. is difference by installation condition)
