c) Adjust production using the potentiometer according to the level of chlorine desired.
Indoor pools or pools with covers
If swimming pool water is not exposed to UV rays, then the chlorine content may become
excessive and therefore corrosive.
It should significantly reduce the production of your electrolyzer when the pool is covered
(minimum 50%).
7. Chlorine analysis method
The analysis should be made at approximately the same time and the same place (at a
point equidistant between the backflow and the skimmer). The chlorine produced by your
salt chlorinator is very volatile and the reading of its content may vary according to different
parameters (UV, number of bathers, organic matter, etc.). If there are an exceptionally high
number of bathers, then we advise you to switch the filtration to manual mode in order to
compensate for chlorine deficit.
8. Checks and maintenance
- Adding salt:
Check the salt level (usually once or twice a week). If the concentration is less than 4g / l, add
salt by the calculation next:
Q = (4-T) x V
Q = quantity of salt to be added in Kg 4 = salt content to be respected
T = measured salt content in the pool V = volume of the pool in m3
- Adding chemical products:
Always stop the device before adding chemical products directly to the pool. Wait for the
chemical products to dissolve before turning the salt chlorinator on again.
Presence of hydrogen peroxide: This product cancels the chlorine reading for approximately 3
weeks.
The sterilizer produced by your chlorinator is compatible with most swimming-pool water
treatment products, with the exception of those containing PHMB polymers. In all cases, stop
the chlorinator while you add products and until they have been completely dissolved.
- Wintering:
If the filtration of the pool is maintained during the winter months, we recommend turning
the chlorinator off when the temperature falls below 15ºC.
- Checking chlorine level:
This material is by no means a chlorine regulator. The chlorine level can vary significantly
depending on the temperature, attendance, chemicals introduced into the pool water.
A regular control of chlorine in the pool water is necessary. Adjust chlorine production if nee-
ded in accordance with paragraph 4.
Warning:
If you later add a shelter over your pool, such as a telescopic shelter, remember to adjust
chlorine production if necessary by reducing the power delivered to the electrode.
-Encrusted electrode:
The electrode must have a clean appearance without lime scale encrustations. If need be,
de- scale the electrode by placing it in a solution containing 80% water and 20% chlorhydric
acid. Then check why the electrode got encrusted:
