3 Clean input and output leads
• Connect each of the 6 capillary tubings attached to connec-
tion piece 98 98 to the pump one after another, and pump
through ultrapure water.
• Check whether solution emerges from connection piece 98 98.
If one of the input or output leads remains blocked, replace
the connection piece (order number 6.2832.010).
4 Clean suppressor rotor
• Clean the sealing surface of suppressor rotor 99 99 using a lint-
free cloth and ethanol.
5 Insert suppressor rotor
• Insert suppressor rotor 99 99 in suppressor holder 100 100 in such a
way that the tubing connections at the rear of the rotor fit in
the corresponding openings inside the rotor, and that one of
the three holes in the rotor can be seen from below in one of
the openings of the holder.
• If the rotor has been inserted correctly, its sealing surface will
be about 4 mm inside the holder. If this is not the case, bring
the rotor into the correct position from below with the aid of a
sharp object (e.g. a screwdriver).
6 Clean connection piece
• Clean the sealing surface of connection piece 98 98 using a lint-
free cloth and ethanol.
