For an overview of the rotors, see figure , page 29
Insert the rotor (21-3) into the housing (21-4) in such a way that
￭
the tubing connections on the rear of the rotor fit into the corre-
sponding recesses inside the housing and one of the three holes
of the rotor is visible from below in the slot of the housing (21-5).
NOTE
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).
