Inspecting And Cleaning The Cell Electrode - Pool Pro CPP Series Installation & Operating Instructions Manual

8. CHLORINATOR MAINTENANCE

8.2 Inspecting and Cleaning the Cell Electrode

Reverse Polarity cells (CPPS models) should not normally require cleaning, however, in areas with
very hard water all calcium may not be removed. 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.
All salt chlorinator cells must be cleaned before scale/calcium builds up to the point where the
electrode gaps in the Cell are bridged. If the Cell has excessive calcium deposit, this may
damage the electrode coating, as the bridging causes rubbing on the plate coating and this
will affect the operation.
Check the Cell frequently to prevent the accumulation of pool debris that for any reason may
have by-passed the pool filter, particularly after backwashing.
Check that the 0-ring is clean, greased with silicone grease (DO NOT use petroleum based jelly)
and securely located 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 instruction supplied.
• 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.
HANDY TIP: Returning this mix to your pool only returns the calcium you just removed, so
you may be better off reusing the solution until exhausted then disposing of it. Always
store this solution in a safe method as advised on the container.
• Do not scratch or bend the cell plates in the Cell Housing.
• Ensure that the 0-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 and 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.
