￭ Check whether solution emerges at the MSM connecting piece
(44-2). If one of the supply or discharge lines remained blocked,
the SPM connecting piece (44-2) must be replaced (order number
6.2832.010).
4 Cleaning the MSM rotor A
￭ Clean sealing surface of the MSM rotor A (44-3) with ethanol
using a lint-free cloth.
5 Inserting the MSM rotor A
Caution
An incorrectly inserted MSM rotor A (44-3) can be destroyed
during start-up.
￭ Insert the MSM rotor A (44-3) into the MSM housing (44-4) 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 the MSM rotor A is visible from below in
the slot of the MSM housing (44-5).
￭ If the MSM rotor A (44-3) is correctly inserted, its sealing area will
be approx. 4 mm within the MSM housing (44-4). 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).
6 Cleaning the MSM connecting piece
￭ Clean sealing surface of the MSM connecting piece (44-2) with
ethanol using a lint-free cloth.
7 Inserting the MSM connecting piece
￭ Insert the MSM conencting piece (44-2) into the MSM housing

pins of the MSM connecting piece fit into the corresponding
recesses on the MSM housing (44-4).
8 Connecting and conditioning the MSM
￭ Reconnect the MSM to the IC system.
￭ Before switching the MSM over for the first time, rinse the three
