1 SAFETY PRECAUTION
Cautions for using with the outdoor unit which adopts R407C refrigerant.
· Do not use the existing refrigerant piping.
-The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit.
· Use “low residual oil piping”.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the lubricant will result.
·Store the piping to be used during installation indoors with keep both ends sealed until just before brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
·Use ESTR , ETHER or HAB as the lubricant to coat flares and flange connection parts.
Use liquid refrigerant to seal the system.
-If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop.
· Do not use a refrigerant other than R407C.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration.
· Use a vacuum pump with a reverse flow check valve.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricant deterioration.
