So please check the cell at regular intervals to see if there are any white deposits on the
electrodes. With the right water balance you will need to clean the cell far less often.
To reduce cell scaling, put product designed to lower the pH (lower pH) into the
skimmer while the filter pump is working. This will clean the cell (if it is not too dirty)
and slightly lower the pH, which should be maintained at around 7.2.
If the cell is very dirty (white deposit clearly visible on the cell screen), clean it. To do
this, stop the pump, close any open isolating valves, undo the nut and remove the
electrodes from their housing.
Method 1:
Put one measure of hydrochloric acid to five measures of water into a
container, and leave the cell immersed in this solution for 1 to 4 minutes
depending on how dirty it is. Do not clean the cell too often or leave it
immersed for prolonged periods, as this could damage it.
Method 2:
Pro-MATIC - ESC Models
The ESC units uses a patented system of automatic electronic cell cleaning. Therefore,
under the right working conditions (right water balance, pH below 7.4), the cell hardly
gets dirty at all. That said, small deposits of scale can form, particularly where water
hardness is very high (TH above 30° f). If that case, clean the cell as indicated above for
ESR models.
6.2) S
ALINITY
The salinity of the water has to be checked, particularly at the start of the season, to
make sure the water contains the minimum amount of salt. If salinity is too low, this
will prevent the unit from working effectively (and reduce the amount of chlorine being
produced), and sooner or later will damage the cell.

ALANCE
pH has to be monitored and maintained at around 7.2. If it is too high, scale will form
on the cell more quickly.
