Insert the new rotor (11- 3 ) into the housing (11- 4 ) in such a way
that the tubing connections on the rear of the rotor fit into the
corresponding recesses inside the housing and one of the three
holes of the rotor is visible from below in the slot of the housing
(11- 5 ) .
NOTICE
The rotor's sealing surface is located approx. 4 mm deep inside the
suppressor drive if the rotor is inserted correctly.
If this is not the case, then the rotor must be moved into the cor-
rect position using careful turning. If the rotor cannot be turned or
removed, it can be moved into the correct position from below by
means of a pointed object (e.g. a screwdriver).
