■■■■■■■■■■■■■■■■■■■■■■ 3 Installation 3 Connecting the pressure side Note Depending on the use of the peristaltic pump, on the pressure side you can either connect: ■ ■ Case A: a 6.2744.180 pump tubing connection with filter (see Figure 6, page 17) or Case B: a 6.2744.160 pump tubing connection without filter (see Figure 7, page 17). For pumping the auxiliary solutions to the MSM or to the SPM, a 6.2744.180 pump tubing connection with filter must be used. Case A: 6.2744.
■■■■■■■■■■■■■■■■■■■■■■ 3.4 Peristaltic pump 1 Union nut 3 Tubing olive 2 ■ ■ ■ ■ Adapter Slide union nut (7-1) onto the pump tubing. Select a suitable adapter (7-2) and slide it onto the pump tubing. The type of adapter depends on the pump tubing (see Table 1, page 18). Place the tubing olive (7-3) onto the pump tubing. Screw the union nut (7-1) onto the tubing olive (7-3). 4 Inserting the pump tubing ■ ■ Press the contact pressure lever all the way down.
■■■■■■■■■■■■■■■■■■■■■■ 3 Installation Set flow rate The contact pressure of the tubing cartridge must be adjusted in order to regulate the flow rate. Proceed as follows: Set the contact pressure 1 ■ ■ ■ ■ Fully loosen the contact pressure lever (5-5), i.e. press it all the way down. Switch on the peristaltic pump. Raise the contact pressure lever one step at a time until liquid flows. When liquid starts flowing, raise the contact pressure lever by an additional 2 ratchet increments.

■■■■■■■■■■■■■■■■■■■■■■ 5 Handling and maintenance 5 Handling and maintenance 5.1 General information 5.1.1 Care Warning The instrument housing must not be opened by untrained personnel. The instrument requires appropriate care. Excess contamination of the instrument may result in functional disruptions and a reduction in the service life of the sturdy mechanics and electronics.
■■■■■■■■■■■■■■■■■■■■■■ 5.2 Door 5.1.4 Shutting down If the instrument is shut down for a longer period of time, the entire IC system must be rinsed as follows to rid it of salts in order to prevent eluent salts from forming crystals which may cause subsequent damage. ■ ■ 5.2 rinse all capillaries and the Dosino with methanol/ultra pure water (1:4), rinse all pump tubings of the peristaltic pump with ultra pure water. Door Caution The door is made of PMMA (polymethylmetacrylate).
■■■■■■■■■■■■■■■■■■■■■■ 5 Handling and maintenance Caution The 6.1826.xxx pump tubings consist of PVC or PP and therefore must not be used for rinsing with solutions containing acetone. In this case, use other pump tubings or use another pump for rinsing. 5.3.2 Maintenance 5.3.2.1 Pump tubing The pump tubing used in the peristaltic pump is a consumable whose service life is restricted.

■■■■■■■■■■■■■■■■■■■■■■ 5.4 Suppressor/SPM Regenerating the suppressor 1 Disconnecting the suppressor/SPM from the IC system ■ Disconnect the capillaries of the suppressor/SPM labeled with regenerant and rinsing solution from the IC system. 2 Connecting the suppressor/SPM to the high pressure pump ■ Connect the inlet capillary for the regeneration solution (labeled with regenerant) to the outlet of the high pressure pump with the aid of a coupling (6.2744.
■■■■■■■■■■■■■■■■■■■■■■ 5.4.4.3 5 Handling and maintenance Cleaning the suppressor In the following cases, it may be necessary to clean the suppressor/SPM: ■ ■ ■ Increased backpressure on the connection tubings of the suppressor/ SPM. Blockage of the suppressor/SPM which cannot be eliminated (solutions can no longer be pumped through the suppressor/SPM). Jamming of the suppressor/SPM which cannot be eliminated (suppressor/SPM can no longer be switched over).
■■■■■■■■■■■■■■■■■■■■■■ 5.4 Suppressor/SPM 5 Inserting the rotor Caution An incorrectly inserted rotor can be destroyed during start-up. ■ ■ Insert the rotor (11-3) into the housing (11-4) in such a way that the tubing connections on the rear of rotor fit into the corresponding recesses inside the housing and one of the three holes of the rotor is visible from below in the slot of the housing (11-5). If the rotor is correctly inserted, its sealing surface will be approx. 4 mm within the housing.
■■■■■■■■■■■■■■■■■■■■■■ 5 Handling and maintenance Replacing parts of the suppressor Replace the parts of the suppressor/SPM as follows: 1 Disconnecting the suppressor/SPM from the IC system ■ ■ Switch off the instrument. Disconnect all capillaries of the suppressor/SPM from the IC system. 2 Dismantling the suppressor/SPM ■ ■ ■ Unscrew union nut (11-1) from the housing . Pull the connecting piece (11-2) and the rotor (11-3) out of the housing.
