7. Grounding the installation
(optional)
We recommend installing a ground wire to harness
any residual electrical current in the water.
Installation of the ground wire
On the pipe saddle before the chamber.
Install the ground wire in compliance with the
current standards of the country of installation.
8. Tips for proper use
The sodium hypochlorite produced by your
chlorinator helps avoid problems linked to the use
of chemical chlorine (purchasing, storage, daily
supervision, etc).
This process has its production capacity directly
linked to the filtration time of your pool. It is
therefore important to verify that the setting is
sufficient in order to ensure proper water
treatment.
8.1 Digital display
In the factory, the chlorinator is pre-programmed
for maximum electric current depending on the
electrode model.
4 A for chlorinator model 30
7 A for chlorinator model 55
10 A for chlorinator model 95
When the machine runs, the current will be
adapted to production needs, water temperature
and frequency of pool use, as described under the
5.3 Switching “on" heading.
If the machine does not reach the indicated electric
current set-point, it could be due to the following
problems:
a. very-low water temperature b - low salt
concentration
b. problem of connection (poor contact or
improperly-tightened lugs)
c. power-supply section of the electrode cable
is too small for the distance covered (the
longer the cable, the larger the section must
be, to compensate for loss)
8.2 Chlorine and pH testing methods
Testing should be done at approximately the same
time and in the same place (about once a week).
The chlorine produced by your chlorinator is highly
volatile and readings can vary in relation to
different parameters (UV, frequency of pool use,
organic matter, etc).
The chlorine concentration should be between 0.5
and 2.5 ppm. The pH should be between 7.0 and
7.4.
8.3 Shock (breakpoint) chlorination
During the season, when the pool has been used
intensely or the water temperature has been
unusual, if your pool water turns murky, it is best to
do a shock or breakpoint chlorination (see
recommendations for shock chlorination dosage).
8.4 Indoor pools, pools under
shelter or with covers
Pool water that is not exposed to UVs can result in
overly-high chlorine levels that are therefore
corrosive.
For this it is best to considerably decrease
chlorinator production when the pool is covered.
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 reduces
programmed production by 50%.
8.5 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,
depending on the water hardness (TH):
As an indication:
> 50° TH 3 hours
between 50°TH & 20°TH 4 to 20 hours
< 20°TH 20 to 99 hours
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
continue 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 be saved within 10
seconds.
