4 Inserting the new MSM rotor A
Caution
An incorrectly inserted MSM rotor A (54-3) can be destroyed
during start-up.
￭ Insert the new MSM rotor A (54-3) in the MSM housing (54-4) in
such a way that the tubing connections on the rear of MSM rotor
A fit into the corresponding recesses inside the MSM housing and
one of the three holes of MSM rotor A is visible from below in the
slot (54-5) of the MSM housing.
￭ If the MSM rotor A (54-3) is correctly inserted, its sealing area will
be approx. 4 mm within the MSM housing (54-4). If this is not the
case, MSM rotor A must be moved into the right position from
below using a sharp object (e.g. screwdriver).

with ethanol using a lint-free cloth.
6 Inserting the new MSM connecting piece
￭ Insert the MSM conencting piece (54-2) into the MSM housing
(54-4) in such a way that the connector 1 is on top and the three
pins of the MSM connecting piece fit into the corresponding
recesses on the MSM housing (54-4).
7 Connecting and conditioning the MSM
￭ Reconnect the MSM to the IC system.
￭ Before switching the MSM over for the first time, rinse the three
