wrench or socket wrench AF 17 mm).
3. Tighten the lock nut (AF 19 mm) in the opposite direction to the arrow.

Test for leak-tightness
Use the plug to check that the assembly is sealed tightly:
1. Seal the rinse chamber outlet with the plug.
2. Apply pneumatic pressure to the rinse chamber inlet (max. 6 bar absolute pressure).
3. Hold the assembly under water as far as the rinse chamber. In so doing, do not
submerge the drive in the water.
The test is successful if no air bubbles appear.
