Tighten the needle valve bonnets when the charge is complete. Check whether a needle
valve leaks by applying soap bubbles to the valve vent or using a halogen leak detector. If
leakage occurs, contact technical support engineers.

12.15.5 Charging the Remaining Refrigerant
Prerequisites
●
Before starting the compressor, ensure that the unit switch is turned on.
●
Remove the refrigerant cylinder after ensuring that no more refrigerant needs
to be charged.
●
Charge refrigerant in an amount exactly as standard charge required.
Otherwise, the unit may be damaged.
Procedure
Step 1 Tap Start on the home screen.
Step 2 Choose Maint > Diagnostic > Enter to enter the diagnostic mode.
Step 3 Change the compressor rotational speed to 3000 rpm.
Step 4 Open the low pressure valve of the pressure gauge, and charge the remaining
refrigerant from the low pressure needle valve in small flow or intermittently.
