Page 105: Additional Charge Calculation
2-5. Additional charge calculation CAUTION • Do not turn on the power unless all operations are complete. • After evacuating the system, add refrigerant. • Do not charge the system with a refrigerant other than R32. • Always keep to the limit on the total amount of refrigerant. Exceeding the limit on the total amount of refrigerant will lead to malfunction during charging of refrigerant.
Page 106 ¢ If additional refrigerant is required When the piping is longer than pre-charge length, additional charging is necessary. 1. Remove the charging cap from the liquid pipe. 2. Attach a charging pipe hose to the refrigerant cylinder, and connect it to the charging port. 3.

3. Pipe installation 3-1. Caution of piping CAUTION Keep the permissible length of every piping limitation to prevent a defect or cooling/heating failure. • Piping material: – Use the designated size (diameter and thickness) of refrigerant pipes. – Those pipes purchased locally may contain dust inside. Blow out the dust by dried inert gas when using.
Page 110 CAUTION • Brazing: – While brazing the pipes, be sure to blow dry nitrogen gas through them. – If nitrogen gas is not blown through the pipes while they are being brazed, an oxidized layer may form on the inside of the pipes. If this occurs, the cooling efficiency may decrease and the air conditioner unit (compressor, valves, etc.) cause malfunction.
