11. MANUAL CELL CLEANING
Your Innowater chlorinator is provided with a self - cleaning polarity change system
that in normal conditions eliminates maintenance work. However, in exceptional
cases, when the calcium concentration is very high (very hard water, old concrete
pools), polarity change may not be enough to completely eliminate the calcium build
up. Visually inspect the cell regularly to detect the presence of calcium and, if
necessary, clean the cell manually. Let the cell dry completely during one or more
days for the calcium build up to detach by itself. You can help this by slightly knocking
the cell but do not introduce any element that could scratch the electrodes. Their
coating is fragile. You can also use a high pressure water jet. DO NOT USE ANY
METALLIC OR STABBING ELEMENT TO SCRATCH THE ELECTRODES.
If you are not able to remove the calcium build up in the way described, proceed as
follows:
1 Turn off the pump and the chlorinator.
2 Disconnect the power cable for the cell, unscrew the thread lock and extract the
cell.
3 Immerse the electrodes in a hydrochloric acid solution made from 1 part of acid
and 9 parts of water. Do not immerse the rods or the cap of the cell. The hydrochloric
acid will react with the calcium and will dissolve it producing a fizzing sensation.
4 Once the calcium build up has dissolved, rinse the cell immediately with
freshwater, dry the terminal area properly and reinstall the cell in its housing.
Never leave the cell in the acid solution for more than 5 minutes.
Do not scratch the electrodes with metal objects. For safety
reasons, always add the acid into the water and never inversely.
