2.3 Installing the Pump Tube in the Sensor Body
Note: Do not stretch the tubing in
the sensor body, as this could affect
the sensor’s ability to detect liquid
through the pump tubing.
1. Remove the four screws on the pump cover.
2. Remove the front cover of the pump housing.
Note: Always use the proper length
of silicone tubing in the pump body.
An improper length can reduce the
life of the tubing and pump rollers.
The total tube length is 33 inches
(84 cm). Refer to
Figure 3 for the
correct length.
3. Remove the tubing. Locate the black dots on the tubing. The end of the
tube that extends farthest beyond the black dot attaches to the stainless
steel tubing connector.
4. Install the pump tube in the pump housing so the black dots are visible
just outside the pump body.
5. After inserting the new pump tube as shown, reinstall the front cover and
secure it with the four screws until finger tight.
6. Make sure that the tubing extends through the liquid sensor and
out of the controller.
