Wash the pump chamber and channels (wizard)
For the time required, see "Maintenance wizard overview"
1. In the home screen, tap
channels wizard.
2. Follow the steps in the wizard to perform the procedure. See "Wash Pump and Channels
maintenance wizard"
In the following situations, use the Polymer Delivery Pump Cleaning Kit (Cat. No. 4461875) in addition to
the wash pump wizard. The cleaning kit helps to thoroughly clean the polymer delivery pump:
• White residue is present in pump channels, which indicates polymer has dried in the channels of
the pump. This can occur if the instrument is not used for >2 weeks and the shutdown procedure
is not run (polymer is installed). Mechanical malfunctions can also cause dried polymer to appear in
the pump channel.
Note: If this procedure does not clean the pump channels, the pump may need replacement.
• A contaminant in the polymer delivery pump is suspected of causing problems. The check valve
fitting might be clogged or contaminated.
For information on using the pump cleaning kit, see Polymer Delivery Pump Cleaning Kit RUO Product
Information Sheet (Pub. No. 4414004).
Flush the water trap (pump trap)
Flush the water trap monthly to prolong the life of the pump and to remove diluted polymer from the
pump.
Note: Leave the water trap filled with distilled or deionized water.
1. Fill the supplied 20 mL, all-plastic Luer lock syringe (in the Polymer Delivery Pump Cleaning Kit,
Cat. No. 4461875) with distilled or deionized water. Expel any bubbles from the syringe.
IMPORTANT! Do not use a syringe smaller than 20 mL. Doing so may generate excessive
pressure within the trap.
2. Open the Luer fitting by grasping the body of the fitting and turning it to loosen.
