2.2 CONNECTING THE PVC ACID TUBE
Before installing the unit in position on the wall or post, the length of the PVC tubing provided should be
measured and taken into consideration. Ensure the Controller and Cell are close enough for the power
supply lead to reach the cell and sufficient PVC tube exists to connect Acid Container and Cell. To avoid
loss of water from the system, close all stop valves before cutting any lines.
Thread the PVC tube through the hole in the cap or shoulder of the chemical container and fit the non-
return or check valve and the weight. Ensure that the non-return valve is fitted correctly (arrow indicates the
direction of flow) Drop the weight, with the non-return valve into the bottom of the container.
Connect the other end of the PVC tube to the inlet of the acid pump on the underside of the Controller.
Connect the remaining hose from the outlet of the acid pump on the underside of the controller. The
remaining end of the PVC hose should be pushed through the cable gland in the end of the Cell Cap so
that it protrude 5 mm on the inside.
TIP: Soaking the ends of the PVC tubing in hot water or gentle heating with a lighter makes it easier to
push onto the barb. When installing acid container in a filter enclosure, which has no ventilation, it is
recommended that the hole in the cap of the container is cut or drilled to fit tightly around the tubing, so that
fumes from the acid will not corrode the equipment. It will be necessary to drill a second hole in the cap
fitted tightly with a length of tubing which should then be vented outside the filter enclosure. This procedure
is recommended only where the filter enclosure has no ventilation and is to protect the equipment.
