3 Cleaning the inlets and outlets
￭ Connect in turn each of the 6 PTFE capillaries fastened on the
connecting piece (36-2) to the high pressure pump (see Chapter
3.9, page 28) and pump through ultrapure water.
￭ Check whether solution emerges at the connecting piece. If one
of the inlets or outlets remains blocked, the connecting piece
must be replaced (order number 6.2835.010) (see "Replacing
parts of the suppressor", page 78).
4 Cleaning the rotor
￭ Clean the surface of the rotor (36-3) with ethanol using a lint-free
cloth.
5 Inserting the rotor
Caution
An incorrectly inserted rotor can be destroyed during start-up.
￭ Insert the rotor (36-3) into the housing (36-4) in such a way that
the tubing connections on the rear of 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 (36-5).
￭ If the rotor is correctly inserted, its sealing surface will be approx.
4 mm within the housing. If this is not the case, the rotor must be
moved into the right position from below using a sharp object.
6 Cleaning the connecting piece
￭ Clean the surface of the connecting piece (36-2) with ethanol
using a lint-free cloth.
7 Inserting the connecting piece
￭ Insert the connecting piece (36-2) into the housing in such a way
that the connector 1 is on top and the three pins of the connect-
ing piece fit into the corresponding recesses on the housing.
￭ Reattach the union nut (36-1) onto the housing and tighten by
hand (do not use a tool).
8 Connecting and conditioning the suppressor
￭ Reconnect the suppressor to the IC system.
￭ Before switching the suppressor over for the first time, rinse each
of the three suppressor units with solution for 5 minutes.
