Note! The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

Preparatory work

Preparing the high pressure side (HP) service valve

Warning! Follow the safety instructions for work on air conditioning systems.




The high pressure side's (HP) service valve is concealed under the cover above the air conditioning aggregate.

Remove:
- the screws, 2 pcs, at the cover's right hand section at the hood's height adjustment rubber (A)
- the screw, 1 pcs, that holds the air intake (B) and remove it.
Lift up the plate to access the service valve and connect the high pressure side's (HP) refrigerant hose.

Draining

Connections for draining

Note! The ambient temperature must be greater than 20 °C.

Hint: The fastest way is to connect the recycling unit to the service valves on both the high-pressure (HP) and low-pressure (LP) sides at the same time.




Switch off the engine.
Check/measure the volume of any oil that drains with the refrigerant.

Note! The recycling unit must have an oil separator. The oil separator must be of a type that allows the amount of oil in the refrigerant to be measured.
