Excessive force can result in brush and possible cell damage. If the brush does
not go into the cell, pull the brush out and examine the cleaning tip for damage.
Use all precautionary steps to prevent damage to the instrument and
personal injury.
Items to collect:
• Absorbent cloth
• Allen wrench
• Cleaning brush
1. Put an absorbent cloth under the instrument to catch any liquid that
drains from the clean-out port. Refer to
Figure 6 .
2. Put the brush into the clean-out port until there is resistance.
3. Gently push the brush into the sensor flow cell with a twisting motion.
4. Operate the instrument with clean sample fluid. To purge any
trapped air in the clean-out line:
a. Put an absorbent cloth over the wrench and slightly loosen the
clean-out cap while the sample run is in progress. Fluid and air
come out quickly when the cap is loosened.
b. Continue the process until no more air comes from the port.
5. Tighten the clean-out port cap snugly. To avoid damage to the
threads, do not over tighten the cap.
