B.1. The production of the cell is not sufficient
There are two possible reasons for a cell having low production: The wearing of the cell and the
scaling of the cell.
Wearing
Normally, an ESC or ESR cell should last 5 years under normal conditions with correct
maintenance & operating in swimming seasons ranging from April to October.
The cell will incur more significant wear & tear if used for a higher frequency for an extended
period of time (e.g.; cell sanitizing swimming pools for medical use).
Below is an example of a cell which has had its central plate worn out by heavy use.
It is recommended that the unit be turned off when the water temperature falls lower than 15°C.
Scaling of the cell
Scaling of the cell can occur when the pH of the water is too high, although the units ESC &
BMSC are self cleaning, it is still possible to find the cell full of scales. In case of scaling of an
ESC or BMSC cell, the pH of the water of the pool has to be adjusted lower (between 7 and
7.4).
Clean the cell with a mixture of 2/3 of water and 1/3 hydrochloric acid. The owner will then have
to maintain the pH of the water at its normal value (between 7 and 7.4) by adding some “pH
minus” when necessary.
B2. The cell is full of scale (white deposit on plates)
Refer to above chapter (Scaling of cell) which is a cause of scale production that can make the
unit inefficient. This is not common for self cleaning units such as the EcoMatic ESC, ESCpH
and also EcoSALT but is more common for units without self cleaning system such as the
EcoMatic ESR.
