Valve module
To replace the rinse station tubing:
1. Shut down and unplug the sampler.
2. Gently push the sampler arm about 30 cm away from the home position.
3. Carefully disconnect the rinse solution inlet and drain tubing.
4. Rotate the rinse station tube to the left by a quarter of a turn.
5. Lift the rinse station tube straight up and remove from the mounting block.
6. Connect the new rinse solution inlet and drain tubing.
7. Push the rinse station tube into the mounting block and rotate it clockwise by quarter
of a turn.
The peristaltic pump is susceptible to acid damage. The cartridges and cartridge holders
can also become acid damaged.
•
After daily use, rinse the cartridges in deionized water to wash off any spills that may
have come in contact with them.
•
Clean the pump surfaces, except the rollers, with a wet cloth. Dry all surfaces well.
•
To remove rust from the rollers, clean with steel wool. Apply a very light coat of
silicone spray to a lint-free cloth and hold it on the moving rollers. The silicone will act
as a rust inhibitor.
•
Check for wear, cracks or acid damage on the cartridges and holders. Replace as
necessary, to make sure proper flow during analysis.
•
Replace pump tubing as soon as it start to show signs of wear, such as flattened
sections (approximately once per month depending on the run frequency).
•
If a pump tube bursts, immediately clean all cartridges, holders and the pump. Any
spill that is not cleaned immediately can result in damage to the pump and/or parts.
•
If the pump speed seems too fast or too slow when the speed is set at 35, follow the
pump test in the troubleshooting guide to make sure the pump is operating properly.

•
Keep all surfaces clean. Use a damp cloth to clean the module surfaces. Dry all
surfaces thoroughly. If an acid spill occurs, neutralize the acid with baking soda and
then proceed to clean all the surfaces.
CAUTION
Potential Chemical Hazard. Turn off System Unit power before connecting or
disconnecting the valve module.
CAUTION
Potential Chemical Hazard. Tubing may contain chemical hazards from reagents
used in analysis. Use standard laboratory practices when handling and replacing
tubing.
