5. Tighten the adjustment screw slowly (turn clockwise) until droplets just start
forming at the end of the SAMPLE OUT side of the sample tubing.
6. Tighten the adjustment screw until you see a smooth flow of bubbles (3 turns on
the peristaltic pump). Add an additional three more turns.
7. Turn off the pump. The tension is now correctly set. No bubbles should be seen
in the sample tubing once the sample tube is kept in the solution.
Cleaning the Pump
Periodically inspect the peristaltic pump rollers to make sure they are clean and move
freely. Clean the exterior of the pump with a cloth moistened with water.
The pump head on the peristaltic pump can be removed and cleaned if necessary. A
replacement pump head is available (Part No. 09220266).
Removing the Pump Head on the Peristaltic Pump
To remove the pump head on the peristaltic pump:
1. Remove the pump tubing.
2. Unscrew the large screw in the center of the pump head. Place the screw and
washer in a secure place.
3. Lift the pump head off. To clean the pump head, use water or a mild solvent and
dry thoroughly.
4. Return the pump head to the pump. Orient the pump head by aligning the notch
on the bottom of the pump head with the pin on the shaft. The pump head must
click in this slot for a proper fit. Replace the washer and tighten the screw.
Caution
Attention
If a spill occurs on the pump, immediately clean it up. A corrosive spill
could damage the pump.
