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.
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.
