The electrode has been designed for Reverse Polarity cleaning and Velocity cleaning. It is normal for one of the
outside plates to build up a white deposit. This should be removed when the unit changes polarity. The deposit
will then form on the other side.
The amount of deposit will depend mostly on the running time, calcium level in the water and pH level. If the
calcium level in the water is above 250ppm or other metallic contaminants are present, then it may be necessary
to acid wash the electrode periodically.
To acid was the electrode, prepare 1 Litre of dilute acid solution as follows:
Fill 900ml of water into a plastic bucket. Add 100ml of swimming pool grade hydrochloric acid.
Note: Pay attention to the safety precautions when handling acids.
• Disconnect power to the chlorinator.
• Uncouple the two pipe connectors under the electrode. Do not disconnect the electrical lead.
• Invert the electrode assembly and rest it on a flat surface.
• Clear any accumulated debris from the plates. Do not scrape the plates.
• Pour the diluted acid into one of the ports until the electrodes and white deposits are completely
immersed.
• Stand for 10 to 15 minutes.
• Discard the solution in the electrode - Do not put it back into the pool.
• If deposits remain, then repeat the process.
• When the electrode is sufficiently clean, flush it with fresh water.
• Refit the electrode to the pipe work. Ensure that the O rings are correctly seated, grit free and lubricated
with non-acetic silicon grease.
