Refrigerant charging

How to add refrigerant

1.Connect manifold gauge to the gas side service valve.

2.Take the trial operation with the cooling trial operation mode.

3.Perform trial operation for longer than 10 minutes and add refrigerant based on the below pressure table.

❋❋Purpose of pressure table : If additional refrigerant filling is needed due to the leakage of the refrigerant or re-installation, add refrigerant using pressure table.

5. After adding refrigerant, fasten cap nuts firmly.

• Always use R-22 refrigerant to avoid damage of the unit or an explosion.

CAUTION • Must keep the quantity of refrigerant by using a balance. Do not use a manometer or not depend on your experiences.
