￭ Pull the SPM connecting piece (53-2) and the SPM rotor A (53-3)
out of the SPM housing (53-4). The SPM connecting piece and
the SPM rotor A normally stick to one another - if this is not the
case: Take a sharp object, insert into the slot (53-5) in the SPM
housing, and pull out the SPM rotor A (53-3) in this way.
￭ Detach the SPM connecting piece (53-2) from the SPM rotor A
(53-3).
3 Cleaning the supply and discharge lines
￭ Connect in turn each of the 6 capillary tubings fastened on the
SPM connecting piece (53-2) on the high pressure pump(see
Chapter 3.10, page 37) and pump through ultra pure water.
￭ Check whether solution emerges at the SPM connecting piece
(53-2). If one of the supply or discharge lines remained blocked,
the SPM connecting piece (53-2) must be replaced (order number
6.2835.010).
4 Cleaning the SPM rotor A
￭ Clean sealing surface of the SPM rotor A (53-3) with ethanol
using a lint-free cloth.
5 Inserting the SPM rotor A
Caution
An incorrectly inserted SPM rotor A (53-3) can be destroyed dur-
ing first use.
￭ Insert the SPM rotor A (53-3) into the SPM housing (53-4) in such
a way that the tubing connections on the rear of the SPM rotor A
fit into the corresponding recesses inside the SPM housing and
one of the three holes of the SPM rotor A is visible from below in
the slot (53-5) of the SPM housing.
￭ If the SPM rotor A (53-3) is correctly inserted, its sealing surface
will be approx. 4 mm within the SPM housing (53-4). If this is not
the case, SPM rotor A must be moved into the right position from
below using a sharp object (e.g. screwdriver).
6 Cleaning the SPM connecting piece
￭ Clean sealing surface of the SPM connecting piece (53-2) with
ethanol using a lint-free cloth.
