Refrigerant Discharging Procedure

REFRIGERANT DISCHARGING PROCEDURE




1. Connect the manifold gauge set to the system.
2. Put a towel under the open end of the center hose.
3. Open the high pressure valve slowly to discharge the refrigerant.

NOTE: If discharging the refrigerant is fast, compressor oil may drain from the system.

4. Check if the towel is stained with oil. If so, gently close the valve.
5. If the manifold gauge reading drops below 3.5 sq.cm, open the low pressure valve slowly.




6. Open the high and low pressure valves slowly in order to drop the system pressure until the gauge indicates 0 kg-sq.cm
