Correcting Low Refrigerant Level

CORRECTING LOW REFRIGERANT LEVEL IN CASE THE SERVICE CAN IS USED




1. Install the charge valve with the handle turned all the way out (valve open) of the service can.
2. Install the adaptor value with the handle turned all the way back (valve close) to the charging valve.
3. Connect the charging hose (blue) to the adaptor valve.
4. Connect the charging hose (blue) to the quick joint (for low pressure).
5. Tighten the handle of the charge valve (valve close), and pierce the service can.
6. Turn the handle of the adaptor valve to bleed the air.




7. Install the quick joint (for low pressure) to the low pressure service valve.

NOTE: The low-pressure service valve should be connected to the low-pressure hose.




8. Start the engine.
9. Operate the air conditioner and set at the lowest temperature (MAX. COOL).
10. Fix the engine speed at 1,500 rpm.
11. Tighten the handle of the adaptor valve (valve open), and replenish refrigerant checking the quantity through the sight glass.

CAUTION: If the service can is inverted, liquid refrigerant may be draw into the compressor damaging it by liquid compression. Keep the service can upright to ensure that refrigerant is charged in gas state.

12. After replenishing is completed, turn the handle of the adaptor valve all the way back (valve close), and remove the quick joint.

NOTE: If any refrigerant is remaining in the service can, close the adapter valve and save the refrigerant for another vehicle. Do not release into the atmosphere.
