MAINTENANCE OF ELECTROLYTIC CELL:

The cell is composed of precious materials, and although proper maintenance can prolong its life to the maximum,

eventually the process of electrolysis will wear away its delicate coating, at which time it gradually ceases to

produce chlorine.
Mineral salts and calcium (scale) are deposited on the outer and the inner plate as electrolysis takes place. This

build up – will interfere with the flow of electrical current in the Cell and thus lowers sanitiser production. It is

essential to inspect the Cell regularly and clean when necessary. The rate at which deposits will form on the plate

differs with each pool and can be influenced by the following:

• Calcium hardness of the water

• Water Temperature

• pH control

• Water which has been chlorinated with calcium hypochlorite for an extended period

• Calcium in the plaster surfaces of a concrete pool

Because these conditions vary so much, check the Cell at least weekly to begin with to see when either scale or a

blue/green soapy substance appears on the plate. You will then be able to determine the cleaning cycle necessary

for your pool (obviously more in summer). The intervals between cleaning could get longer to the point where

cleaning is only necessary a few times each year. One exception is the use of bore water or ground water, in which

case cleaning may always need to be as frequent as once a week.

NOTE:

In areas with hard water, reverse polarity systems may require occasional manual cleaning.

Life of ChloroMatic

®

electrolytic cells vary substantially from one installation to another due to variations in

operating time, water quality and composition, system and cell maintenance. Please ensure that when cell

replacement is necessary you use the correct genuine ChloroMatic

®

replacement cell to match your system. Due

to increased cell output reverse polarity Model ESC40 cells will require earlier replacement than ESC24 Models

operating under equivalent conditions. Model ESC40 systems use the same cell as the ESC24. The correct

ChloroMatic

Replacement cells to use are:

To clean the cell

: Turn off chlorinator. Remove all leads connected to the Head Assembly. Unscrew the Cell by

turning the Head Assembly clockwise – as per instructions, and withdraw from the Cell Housing.

METHOD 1

Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable container 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.
