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 MCS50C cell:
First turn off the power to the controller and the pump, disconnect the cell from
the Power Supply Unit and remove from the pool return line by undoing the unions. Take care not to lose the
O-rings.
Once removed, place the cell upside down (inverted) in a small tub or a suitably sized bucket. Ensure the cell is
stable and won’t tip over. As opposed to the ESC16-40 gram cells, which are placed into a solution of cleanser, the
cleansing fluid is poured into the ESC50 cell.
NOTE: Ensure the plates are fully submersed in the solution for even cleaning.
After a few minutes of soaking, examine the cell for cleanliness and removal of the mineral build up.
If the build up has not been adequately removed, repeat this process until the cell is clean.
When the cell is clean, rinse the cell with clean water and refit to the pipework and controller.
To clean the 16-40g 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 instructions, and withdraw from the Cell
Housing.
NOTE:
If using mineral salts in areas with hard water, reverse polarity systems may require occasional
manual cleaning. Mineral salts can form scale on the cell that isn’t removed through the polarity
reversal process, therefore more frequent manual cleaning may be required. In some cases this
scale is soft enough to remove with a strong jet of water if acid cleaning proves ineffective.
