4.2.3.3. Feeder tube replacement:

• Disconnect the pump from the power supply;
• Ensure that your circulation pump isn't running, or isn't about to run. For above ground pools (or
pools where the water level is higher than the equipment) it may be necessary to close isolation
valves to ensure water doesn't flood from the pool;
• Remove the clear cover of acid dosing pump;
• To remove the squeeze tube:
- Turn the squeeze tube roller so that the roller is vertical;
- Remove the feeder tube from its seated connection on the left of the pump. Alternately, pull
the squeeze tube from its seat and manually rotate the squeeze tube roller clockwise until it is
possible to extract the right-hand side connection from its seat.
• To fit the tube:
- Turn the squeeze tube roller horizontally;
- Insert the connection in its seat on the left of the pump with the curved side towards the floor.
Alternately, push the tube into its seat and manually rotate the squeeze tuber roller clockwise
until it is possible to insert the right-hand side connection into its seat; and
- Refit the clear cover of the acid dosing pump.
