Leak Detection Additive With Filled Refrigerant Circuit, Filling
Note
♦ If leak detection fluid was filled already in a refrigerant circuit
for an earlier repair, note the following: only add new leak de‐
tection additive if the refrigerant oil will be replaced. If only a
portion of refrigerant oil was replaced, only top-off with a cor‐
responding amount of leak detection fluid as well. For exam‐
ple, if 100 ml of refrigerant oil was replaced in a vehicle with
250 ml, add only 1 ml (cm
3
) of leak detection additive.
♦ A small quantity of leak detection additive remains in the serv‐
ice connection. Carefully remove this residual amount so a
leaking area is not detected erroneously upon a later leak de‐
tection.
The cartridge -A- contains 15.4 leak detection additive (one unit
-B- corresponds to 2.5 ml).
– Switch off ignition.
– Remove sealing cap from service connection of low pressure
side in refrigerant circuit.
– Assemble Hand pump -VAS 6201/1- item -1- with cartridge
item -2- -VAS 6201/2- .
– Insert Tube -VAS 6201/8- ( ⇒ page 145 item -7-) into service
coupling and open service coupling by screwing in handwheel.
Hold the hose upward and tighten the handle of the hand pump
just enough until the leak detection additive starts to emerge
from the tube.
Note
Make sure hand pump hose is completely filled with refrigerant.
– Close service coupling and remove tube from locking mecha‐
nism.
