Chlorinator Maintenance; Inspecting And Cleaning The Cell Electrode - Pool Pro CPP Series User Manual & Operation Manual

8. CHLORINATOR MAINTENANCE

Maintenance of your Pool Pro Salt & Mineral Chlorinator is simple and easy. While water chemistry
will always be the most important form of maintenance there are also other pointers to take note of.
• DO NOT cover the Power Pack with towels or similar as it has air vents that need air circulation.
• Keep the chlorinator off at all times during backwash cleaning of your filter by turning the Cell
Switch to the OFF position. Please remember to turn it on once done and return the unit to AUTO
mode.
• Check Power Pack Junction Box screws are tight and Cell leads are in sound condition at least once
a year.

8.1 Inspecting and Cleaning the Cell Electrode

Reverse Polarity cells (CPPS models) should not normally require cleaning, however, in areas with very
hard water a calcium deposit might form on the lower areas of the Cell, the sensor or the sides of the Cell
plates. This will NOT affect the operation of your chlorinator, however you can use Pool Pro Cell Cleaner
to clean the Cell.
Standard cells (CPP models) should be checked every two weeks for calcium build up. Clean at least every
4-8 weeks (or as required) using Pool Pro Cell Cleaner. IMPORTANT: Excessive calcium build up is not a
chlorinator problem but rather a water balance issue.
Chlorinator Cells must be cleaned before scale/calcium builds up to the point where the electrode gaps in
the Cell are bridged as this may cause damage and affect operation. Check the Cell frequently to prevent
the accumulation of pool debris that for any reason may have bypassed the pool filter, particularly after
backwashing. Check that the O-Ring is clean, greased with silicone grease (DO NOT use petroleum based
jelly) and securely seated in the Cell Housing. For cleaning, please follow these steps:
• Switch off the wall outlet switch as this ensures the pump and Pool Pro unit will not turn on.
• Unscrew the Cell Locking Ring and remove the electrode for inspection. If calcium build-up is present,
immerse the electrode in Pool Pro Cell Cleaner.
• A solution can be made by mixing 1 part Hydrochloric Acid to 10 parts of water. If excessive build up is
present a stronger solution may be used to remove the calcium. Using 5 parts of water will make a
more aggressive solution but will not damage the Cell. You can use Pool Pro Cell Cleaner and if you do
then follow the instructions supplied on the product label.
• Allow the cleaning solution to dissolve the calcium deposits for 10 minutes. Dispose of the cleaning
solution at an approved Council Depot and never into storm water or sewage drains.
• TIP: Returning this mix to your pool only returns the calcium you just removed. You can reuse the
solution until exhausted then dispose of it. Always store the solution safely (refer to product label).
• Do not scratch or bend the cell plates in the Cell Housing.
• Ensure that the O-Ring is clean, greased and properly seated.
• Rinse the electrode in clean water and re-fit the electrode in the Cell Housing, ensuring that the Cell
Locking Ring is hand tight and secure.
• Turn on the wall outlet switch and the pump, the chlorinator will return to the mode it was in before.
• Turn on the unit and confirm chlorine output and timer settings on the Power Pack.
WARNING
A
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
Eye protection, mask and gloves should be worn when cleaning the Cell.
