Draining refrigerant





When draining refrigerant, the recycling unit can be attached to the service valve for both the high pressure side (HP) and the low pressure side (LP). This is the quickest method.
- The engine must be switched off
- Check the amount of oil (if any) that has run out when draining the refrigerant.

Note! 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.
