Pump Module; Setting Up The Rear Seal Wash System - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

4.5 Pump Module

4.5.1 Setting Up the Rear Seal Wash System

The peristaltic pump is installed at the top left in the pump module. The tubing under the
peristaltic pump lever remains compressed and does not relax, thus blocking the wash
solution. This can happen if the pump is not running for a longer period, for example,
during shipment. That is why the pump is shipped with the active rear seal wash tubing
bypassing the peristaltic pump.
1. Verify that the peristaltic tubing (white PharMed
pump.
If the tubing is not yet engaged in the peristaltic pump, press the lever to the right, place
the tubing in the pump, and release the lever.
2. Fill the seal wash reservoir (250 mL, a reservoir is provided in the accessories kit of
the NCS). Observe the precautions for the composition of the seal wash solution on
page 122.
3. Connect the silicone tubing from the peristaltic pump with the seal wash reservoir. If
necessary, prolong the tubing. (Silicone tubing is provided in the accessory kit of the
module.)
4. Place the seal wash reservoir in the Solvent Rack of the UltiMate 3000 system.
5. The seal wash solution is routed to the drain port at the bottom right of the module.
Verify that drain tubing is connected to the port and routed to an appropriate waste
container (→ section 4.4, page 65).
6. Flush the system with seal wash solution.
a) Remove the seal wash tubing from the detector.
