Draining refrigerant

NOTE:

When draining the refrigerant from the air conditioning (A/C) system, the ambient temperature must be above 20°C

The engine must be switched off.

Connect the recycling unit to the service valves on both the high-pressure (HP) and low-pressure (LP) sides. This is the quickest way to drain the refrigerant.

Check the amount of oil (if any) that has run out when draining the refrigerant. The recycling unit must be equipped with an oil separator. The oil separator must be of a type that allows the amount of oil in the refrigerant to be measured.
