Volkswagen Golf Service & Repair Manual: Connecting air conditioner service station for measuring and checking
| Depending on the type of equipment chosen, there may be
variations in the required procedure; therefore always follow
the user's manual for the equipment being used. |
 Note
| Always follow the procedure described in the user's manual
for your air conditioner service station -VAS 6007A- (or later
model). |
| The charging hoses must only be connected according to the
following work procedure to prevent air or moisture from
entering the refrigerant circuit: |
| – |
Connect air conditioner service station to power supply. |
| – |
Unscrew sealing caps from service station connections or
from connections with valve (see vehicle-specific refrigerant
circuit). |
| – |
Evacuate charging hose. |
Note
| Connect the charging hose to the service connections of the
refrigerant circuit using quick-release couplings. |
Caution
| Do not open the valves in the low- or high-pressure
sides when the engine is running. Otherwise, if the air
conditioning is switched on, the air conditioner
compressor or the air conditioner service station may be
destroyed by a “short circuit” between the high- and
low-pressure sides of the refrigerant circuit. |
|
| – |
Turn hand wheel into quick-release coupling adapter until
the valve in the service connection is definitely open (observe
pressure gauge; do not over-tighten valve). |
| – |
Start the engine and perform the planned tests and
measurements. |
| – |
Compare determined values with specifications
→ Chapter. |
| – |
Before disconnecting the quick-release coupling, close it by
turning out the handwheel. |
