21. Start the engine.
22. Operate the air conditioning and set it to the lowest temperature (MAX. COOL).
23. Fix the engine speed at 1,500 r/min.
24. Tighten the handle of the adaptor valve (valve open) to charge the required volume of refrigerant.
CAUTION: If the bulk container is inverted, liquid refrigerant may be drawn into the compressor, damaging it by hydraulic lock. Keep the bulk
container upright to ensure that refrigerant is charged in gas state.
25. After charging with refrigerant, turn the handle of the adaptor valve back all the way (valve closed).
26. Tighten the charge valve handle (valved closed). Disconnect the quick joint (for low pressure) from the low-pressure service valve.
CORRECTING LOW REFRIGERANT LEVEL WHEN THE BULK CONTAINER IS USED
1. Install the adaptor valve with the handle turned all the way in (valve closed) to the charge valve.
2. Connect the charging hose (blue) to the adaptor valve.
3. Connect the charging hose (blue) to the quick joint (for low pressure).
4. Open the valve of the bulk container.
