Refrigerant Circuit, Charging With Service Station

NOTE:

The entire refrigerant charge can be added to either the high or low pressure side. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS .

The work procedure is always to be performed as described in the operating instructions for the A/C service station.
Before pouring in refrigerant, correct the quantity of refrigerant oil. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS .
Make sure the A/C Service Station is standing at the same level as the vehicle (maximum difference: 50 cm) when charging the refrigerant circuit. If a difference in height is large enough, a difference between the amount of refrigerant displayed on the service station and amount actually filled in the circuit will result (depending on the version of the A/C Service Station). The ability of the A/C Service Station to perform an exact filling can change.

-- Turn off the ignition.

-- Evacuate the refrigerant circuit using the service station. Refer to REFRIGERANT CIRCUIT, DISCHARGING WITH SERVICE STATION .

-- Screw out handwheel at quick-release coupling adapter (to close it).

-- Allow an amount of refrigerant to flow into charging hose.

-- Check the charging cylinder.

-- Screw in hand wheel at the quick-release coupling adapter (to open it) and charge with the specified quantity of refrigerant.

-- Turn off the service station.
