Self cleaning salt chlorinators are meaning less maintenance for customers but many customers still have manual cleaning systems that need the cells cleaned and even with self cleaning systems, they still need cleaning at times, just less often.
This cell shown is a manual cleaning cell of one of our customers. The white material is calcium. Cells attract positive ions (so they can attract sodium/salt) and therefore it has to attract calcium. This calcium needs cleaning off so the cell can work effectively.
This cell also shows the middle plate is getting shorter than the others, as the cell wears out. Below is how the manufacturer recommends to clean this particular cell.
Cleaning Your Chloromatic Cell
Turn off the chlorinator unit. Remove all leads connected to the Head Assembly. Unscrew the Cell by turning the Head Assembly clockwise – as per instruction manual, and withdraw from the Cell Housing
METHOD 1 Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable container carefully and immerse the Cell in this solution. It should not take longer than a few minutes to clean, if it does the Cell should be cleaned more frequently. If the build – up is not excessive it may be possible to clean the cell plates with a jet of running water. Return the Cell to its Housing and connect leads to the Head Assembly.
METHOD 2 As an alternative, an approved commercial Cell cleaning solution can be used a number of times effectively.
RECOMMENDED SALT LEVEL RANGE for your pool water: 4500 – 6000ppm
Low salt levels will destroy the coating on the Anode plates and you mean you need to replace your cell more often
