4 Insert actuator rotor
• Place actuator rotor 87 in actuator holder 88 so that the
tubing connections on the rear of the rotor fit into the
corresponding recesses inside the holder and one of the
three holes of the rotor can be seen from below in one of the
openings of the holder.
• When the rotor has been correctly inserted its sealing surface
is approx. 4 mm inside the holder. If this is not the case then
the rotor must be brought into the correct position from below
by using a pointed object (e.g. screwdriver)..
5 Clean connection piece
• Clean the sealing surface of connection piece 86 using a lint-
free cloth and ethanol.
6 Insert connection piece
• Insert connection piece 86 in actuator holder 88 so that
connection "1" is at the top and the three connection piece
projections fit into the corresponding recesses in the holder.
• Tighten up sleeve nut 85 on the thread of suppressor holder
88 by hand (do not use any tools).
7 Connect and condition suppressor module
• Reconnect suppressor module to the IC system (see Section
5.1).
• Before moving the suppressor to the next position for the first
time rinse the 3 actuator units with solution for 5 min.
Connect and condition sample preparation module
• Reconnect sample preparation module to the IC system (see
Section 6.1 and Section 6.2).
• Before moving the suppressor to the next position for the first
time rinse the 3 actuator units with solution for 5 min..
8 Check actuator step
• Check that the actuator rotor moves to the next position as
described in Section 9.2.6.3 and readjust it if necessary.
