• Refill an air-conditioner with refrigerant when refrigerant has been leaked at installing or using.
1. Purge air (for new installation only).
3. Connect the tank to refill with Refrigerant.
4. Set the unit to cool operation mode.
7. Stop operation of the air conditioner.
5. Check the pressure indicated by the
pressure gauge (low pressure side).
• Standard pressure is should be
4.5~5.5kg/cm 2 in a reqular, high operation
mode. (1-UNIT operating)
8. Close the 3-way valve, disconnect the
pressure gauge, and open the 3-way
valve again.
9. Close the cap of each valve.
6. Open the refrigerant tank and fill with
refrigerant until the rated pressure is
reached.
• It is recommended not to pour the
