3.7 Replacing the Pump Tube
The pump tube is subject to wear during pump
operation. It should be replaced when the GLS
displays the pump tube warning at 500,000
pump counts, or when inspection of the tube
reveals any cracks along its side.
WARNING
Moving parts can cause injuries. Remove power
before replacing the pump tube.
To replace the pump tube:
1. Disconnect the power from the 12V Input
Power connector.
2. Loosen the two thumbscrews and remove
the liquid detector cover.
3. Loosen the four thumbscrews and remove
the pump housing cover.
4. Pull the pump tube out of the pump
housing. Rotating the pump rollers will help
free the tube.
5. Pull the pump tube from the bulkhead
fitting and disconnect the suction line.
6. Clean the inside of the pump housing if
necessary.
