Refrigerant pipe processing
Apply proper torque to flare nuts
Never use existing refrigerant piping.
The large amount of chlorine in conventional refrigerant and refrigerant oil in the existing piping will cause
the new refrigerator to deteriorate.
Store the piping to be used during the installation indoors and keep both ends of the piping sealed until
just before brazing.
If dust, dirt or water gets into the refrigerant cycle, the oil will deteriorate and the compressor may fail.
Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerant oil to coat flares and flange con-
nections before connecting.
The refrigerant used in the unit is highly hydroscopic and mixes with water which will degrade the refrig-
erant oil.
