If your automatic cover has a relay on it, it is
suggested that this be connected to the special
terminal "volet".
An indicator signals detection of a closed cover
and the machine automatically
programmed production by 50%.

7. - Adjusting the reverse
polarity time
Your chlorinator was factory-set for a change of
polarity every 4 hours. It is possible to modify this
reverse polarity time from 1 to 99 hours, depen-
ding on the water hardness (TH):
As an indication:
> 50° TH
between 50°TH & 20°TH ≅ 4 to 20 hours
< 20°TH
If the electrode scales-up, you should shorten the
reverse polarity time.
Adjusting: Switch the machine off. Then press
on + while turning the machine on and con-
tinue pressing the key for 10 seconds until
the screen displays the change of polarity
time in hours.
Release the key and use + or - to change it.
The new value will

7. - Cycle of the machine
Between each change of polarity the box dis-
plays "00" and the + and - indicators light
up for about 2 minutes.
After each reverse polarity time, the unit indi-
cates its maximum current during 2 minutes
then returns to the previous adjustement.

7. - Verification and maintenance
Error signals:
If there is a problem with electric current, voltage
or internal temperature, the machine no longer
displays anything.
Only the indicator stays lit.
The machine will start up again automatically.

E4 Salt Chlorinators - Installation and User Manual
Adding salt:
Check the salt concentration. If the concentration
is less than 4g/l add salt, using the following
equation: Q = (4 - T) x V
Q = quantity of Kg of salt to add
4 = correct salt concentration
T = concentration recorded in the pool
V = pool volume in m 3 .
Always stop the chlorinator before adding any
product whatsoever. Wait until the salt has
dissolved before turning the chlorinator back on
again.
The salt concentration should be checked at
least twice a year.
Winterization:
If pool filtration is maintained during the winter
months, we recommend
chlorinator when the water temperature drops
below 15°C, removing the electrode from the
chamber, and replacing it with the cap that has
been provided for this purpose.
Tips for proper use of the electrode:
The electrode is a wear-sensitive part, and its life
span depends on the following factors:
- Salt concentration:
Never run the chlorinator
concentration less than 3.5 g/l.
- Water temperature and
winterization:
Turn off the machine whenever the water
temperature drops to 15°C or below.
- Adjustments:
Never leave the machine
production unless there is a chlorine shortage. An
"economical" setting would be about 75% of the
maximum current value printed on the side label.
- Reverse polarity:
Your machine is adjustable (see heading
The electrode's life span depends on the number
of changes of polarity performed. For example, it
will wear out less quickly if change of polarity
occurs every 6 hours, and more rapidly if it
occurs every 2 hours.
Scale-covered or furred-up electrode:
The electrode should be clean-looking, without
any scaling.
