1 - Air conditioner service sta‐
tion
Note
The air conditioner compressor is
purged manually.
– Extract refrigerant, if
there is any in the sys‐
tem.
– Empty the used-oil con‐
tainer of the air condi‐
tioner service station.
Note
Some air conditioner service sta‐
tions first separate the oil in the vac‐
uum phase and then fill it into the
used-oil container.
– At the air conditioner
service station, set the
amount of refrigerant to
2 kg and the amount of
oil to 0.
– Connect purging device
for refrigerant circuits -
VAS 6336/1- or purging
device for refrigerant cir‐
cuits - VAS 6337/1- be‐
tween air conditioner
service station and re‐
turn line for refrigerant
circuit.
– Evacuate the refrigerant
circuit for 10 minutes. Then observe the vacuum gauge. If the vacuum persists, fill 2 kg of R134a refrig‐
erant into the circuit. Then, extract and evacuate again and repeat the process.
2 - Refrigerant hose of air conditioner service station
❑ From the low-pressure side of the air conditioner service station (normally coloured blue) to the outlet of
the purging device for refrigerant circuits
3 - Purging device for refrigerant circuits
❑ Different versions and different design e.g. purging device for refrigerant circuits - VAS 6336/1- or purging
device for refrigerant circuits - VAS 6337/1- .
❑ With filter, sight glass, safety valve, heating, refrigerant tank, etc. (depending on version).
❑ Depending on the design of the air conditioner service station and the purging device for refrigerant
circuits, there may be a non-return valve installed at the outlet of the purging device for refrigerant circuits
(to assure the correct direction of refrigerant flow during purging).
4 - Charging hose of flushing device for refrigerant circuits
❑ From connection to high-pressure side of air conditioner compressor on refrigerant circuit (smaller di‐
ameter) to inlet of purging device for refrigerant circuits - VAS 6336/1- or purging device for refrigerant
circuits - VAS 6337/1- .
5 - Adapter to connection for high-pressure side on refrigerant circuit
❑ Adapter - VAS 6338/3- from adapter set for refrigerant circuits - VAS 6338/1-
