930 Compact IC Flex ChS/Deg (2.930.1260)
NOTE
The adapter (6.2842.020) (see "Inserting small rotors", page 31) is
required in order to insert a small rotor into the suppressor drive.
Insert the new 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
corresponding 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).
5 Cleaning the new connecting piece
Clean the sealing surface of the new connecting piece (21-2) with
￭
ethanol using a lint-free cloth.
6 Inserting the new connecting piece
See also Chapter 3.11.1, Page 29
Insert the connecting piece (21-2) into the housing in such a way
￭
that connector 1 is on top and the three pins of the connecting
piece fit into the corresponding recesses on the housing.
Reattach the union nut (21-1) and tighten by hand (do not use a
￭
