CAUTION
The rotor may be destroyed during start-up if not inserted correctly.
Therefore, follow the following instructions exactly.
Inserting large rotors
1 Removing the union nut
Loosen the union nut and remove it.
2 Inserting the rotor
￭
Clean the sealing surface of the rotor with ethanol using a lint-
free cloth.
￭
Insert the rotor into the suppressor drive so that the tubing con-
nections on the rear of the rotor fit into the corresponding
recesses inside the suppressor drive and one of the three holes of
the rotor is visible from below in the slot of the suppressor drive.
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).
3 Inserting the connecting piece
￭
Clean the sealing surface of the connecting piece with ethanol
using a lint-free cloth.
￭
Insert the connecting piece into the suppressor drive so that con-
nector
1
is on top and the three pins of the connecting piece fit
into the corresponding recesses on the suppressor drive.
4 Attaching the union nut
Tighten the union nut on the thread of the suppressor drive by hand
(do not use any tools).
