TO CLEAN THE IN-LINE CELL
Ensure that the Power Supply is turned off – failure to do so may result in the pool pump turning on while the
Cell is not in place. Disconnect the cell lead and flow switch from the Cell and remove the Cell from the pool
return line by undoing the unions, taking care not to lose the o-rings.
METHOD
1. Assemble a blanking cap from the supplied plug, o-ring and lock ring.
2. Install the blanking cap onto the end of the Cell opposite the flow switch port.
3. Secure the Cell in a vertical position with the blanking cap at the bottom, to catch any spills the Cell should
be placed in an acid proof container.
4. Add 50mL of HYDROCHLORIC ACID to 500mL of WATER in a suitable sized container; carefully pour the
solution into the open end of the Cell.
5. Alternatively step 4 can be carried out using an approved commercial cell cleaning solution.
6. As the scale is being dissolved from the plates the solution will foam, when this foaming action has
stopped the Cell is clean and the solution can be returned to the container for future use or discarded
appropriately. NOTE: do not leave the acid solution in the Cell for more than ½ hour.
7. Rinse the Cell out with clean tap water by filling and draining a couple of times, check that all the scale
deposits have been removed, repeat the cleaning process if necessary.
8. Return the Cell to its position in the pipe work and re-connect the cell lead and flow switch.
NOTE: Always add acid to water, never add water to acid. Always wear eye protection
and rubber gloves. Always clean the Cell in a well-ventilated area.
PoolFresh units are also fitted with a Thermal cutout to prevent overheating. If the temperature rises too
high, power is automatically disconnected. The unit will resume operation when it cools down.
