Page 2: Safety Precaution
SAFETY PRECAUTION CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R407C Do not use the existing refrigerant piping. Use liquid refrigerant to seal the system. The old refrigerant and lubricant in the existing piping If gas refrigerant is used to seal the system, the composition contains a large amount of chlorine which may cause the of the refrigerant in the cylinder will change and performance lubricant deterioration of the new unit. - Page 3 [3] Service tools Use the below service tools as exclusive tools for R407C refrigerant. Tool name Specifications Gauge manifold ·Only for R407C. ·Use the existing fitting SPECIFICATIONS. (UNF7/16) ·Use high-tension side pressure of 3.43MPa·G or over. Charge hose ·Only for R407C. ·Use pressure performance of 5.10MPa·G or over.
- Page 4 Cautions for units utilizing refrigerant R410A Use a vacuum pump with a reverse flow check Do not use the existing refrigerant piping. valve. The old refrigerant and lubricant in the existing piping Vacuum pump oil may flow back into refrigerant cycle and contains a large amount of chlorine which may cause the that can cause deterioration of refrigerant oil etc.
- Page 5 [1] Cautions for service (1) Perform service after collecting the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant.
