4.3.3.2. Suction filter installation:
• Feed the acid feeder tube through the lid of your acid container. A 7/32" drill bit is ideal to make this hole;
• Always ensure you drill a venting hole in the lid too (refer Figure 4.2). This is particularly important
if the chemical container is stored in an unventilated area, as the venting port should be used to
extract fumes from the area;
• Insert the end of the tubing in the weight so that it exits from the flared part (refer Figure 4.3);
• Insert the suction filter in the same end of the tubing (refer Figure 4.3);
• Tighten the tubing screwing the weight until it sits on the bottom of the acid drum;
• It is strongly recommended to use the suction filter in all situations. It is the combination of the hose
weight and suction filter that ensures that the acid tube intake does not suck itself flat against the
bottom of the acid drum; and
• Clean it periodically to avoid dry residual of product, accumulation of dirt.

4.3.3.3. 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.
