HOW IT WORKS
Salt chlorination of a pool works by using salt electrolysis to disinfect the water; this
electrochemical process converts the salt present in the water into a disinfectant
(hypochlorite ions).
Once this process is complete, hypochlorite turns back into salt after coming into
contact with organic material (bacteria, cells) or under the e󰀨ect of UV rays or other
sources of light, starting the cycle over again.
In order to maintain a good level of disinfectant in the water, the following guidelines
must be respected:
• A proper concentration of salt in the water: 3 g/l
• Adequate ltration time (as a reminder, a good estimate is: Filtration Time = T°
water / 2)
• A good water balance with a pH between 7.0 and 7.8 (for more information
see Taylor watergram)
• Regular cleaning of your pool to remove any plant debris
• In case of frequent use, consider using the boost function.
WARNING - Salt water chlorination alone will not clear up green water by itself. In
the event of algae appearing (e.g. after a period of high temperatures or frequent
use), it may be necessary to supplement with chlorine tablets. Do not put the
chlorine tablets directly into the skimmer; use a oating dispenser.

OPERATING LIMITS
As with any pool, it’s important that the ltration time is long enough to maintain a good chemical
balance in the pool water, including pH, alkalinity and calcium levels.
The only special requirement to use a salt chlorinator is maintaining proper levels of salt and
stabiliser.
To get the most out of your pool, it is important to maintain these levels in order to avoid corrosion
and scale deposits. We therefore recommended that you test all of the basic parameters of the
water at least once per week.
In addition, we recommended getting your pool water tested by a professional at least twice per
season.
Your local pool store can provide you with the chemicals and steps to take to adjust the chemical
properties of the water.
Don’t forget to let the store know that you use a salt chlorinator.
Check your values and correct them at least once a week:
Parameter Target values Comments
Salinity 3 to 4 g/l Once the salt is dissolved in the water (+/- 24 to
48h), salt concentration will only vary slightly over
the course of the season.
pH level 7.2 to 7.4 Please note, a pH above 7.8 suppresses the
disinfecting properties of hypochlorite.
Free chlorine concentration From 0.5 to 3.0 ppm Measurements must be taken from around the
return inlets when the chlorinator is switched on,
preferably in the morning and out of direct sunlight.
! important !
Stabilizer rate
(Cyanuric Acid)
From 20 to 50ppm Hypochlorite is a relatively unstable disinfectant.
With too low a level of stabilizer, the hypochlorite
will turn back into salt too quickly without having
had enough time to disinfect.
Conversely, with too high a level of stabilizer, the
hypochlorite will be blocked.
Be careful, if the level of stabilizer is much too high,
the pool will have to be partially drained to add
water without stabilizer.
Additional tests
Total alkalinity (TA) From 80 to 150 ppm This level measures the concentration of mineral
salts (carbonates, bicarbonates, hydroxides) in the
water. It stabilizes / bu󰀨ers the water balance. High
TA levels interfere with the e󰀨ects of pH regulation
and scale deposits may begin to appear.
Water hardness From 150 to 300 ppm Water hardness represents the amount of calcium
carbonate present in your water.
In addition, temperature plays a major role in the correct usage of your chlorinator:
Water temperatures lower than 10°C will render the system inoperative (E2 warning will be
displayed)
Water temperatures higher than 32°C will reduce the e󰀨ectiveness of hypochlorite. The addition
of chlorine tablets is therefore recommended for consistently high temperatures; do not place
chlorine tablets directly into the skimmer, use a oating dispenser.
WARNING - the presence of iron in your water (ferruginous water) may lead to
rust deposits in your pool and require the use of a metal sequestrant - please
consult a professional.

FEATURES
The salt chlorinator contains the latest electronic monitoring technology for ease of use.
You can easily adjust the production of disinfectant to suit your needs, maximizing e󰀩ciency while
remaining environmentally friendly. In addition to these easy-to-use settings, it also has a self-
cleaning function for the cell and a self-test mode in the event of a warning or error code.
For example, the chlorinator displays a warning when its detects low salinity levels, improper
temperatures or a lack of water ow (see section on errors codes and xes).
The compact size of the chlorinator and its integrated control panel allows for easy installation
and a smaller footprint. The water inlet and outlet are on the same axis, reducing the need to
rearrange piping.

Prior to installation, please verify the following:
Ensure the electricity and water circulation system are switched o󰀨, and close the valves on the
pipes connected to the chlorinator.
Ensure any pipes used (not supplied) are compatible with the chlorinator.
Dimensions of the 2 types of connectors supplied:
- OPTION 1: 1.5” (metric: Ø50 mm) connectors to be sealed using PVC cement
- OPTION 2: D32 or 38 mm push t connectors
Remove any obstructions
Lubricate the ttings
Ensure the direction of water ow corresponds to the direction indicated on the chlorinator: ‘’
‘’.
The salt chlorinator must be installed on the return line carrying water from the pool lter back
to the return inlets, as shown in Figure 1 (horizontal assembly) and Figure 2 (vertical assembly).
If using with a water heating system, install the chlorinator downstream from the latter. The
chlorinator must be the nal element of the circuit.
Installation without a bypass is possible if your pump has a ow rate of < 10m3/h, however, using
a bypass is strongly recommended to allow the hydraulic circuit to be isolated. If the ow rate of
your pump is > 10m3, a bypass is required.
CASE 1 : Using D50mm PVC pipes:
If you need to cut existing D50mm PVC pipe, the length of the cut must be 230 mm. Make sure to
use special PVC cement for 1.5” (D50) connectors.

CASE 2 : Using D38mm or D32 pipe:
When using this type of pipe, another length of pipe, minimum 50cm (not supplied), equivalent to
the one in place must be added to the outlet of the lter; consider adding a valve (if not already
present) just after the chlorinator to be able to isolate this section and facilitate maintenance.
INSTALLATION
If you want to insert the chlorinator into an existing pipe (or t on
to a pipe), you must cut out a section measuring 230mm in length.

The power supply of the salt chlorinator must be connected to a separate power source equipped
with a 30mA residual current device, sheltered from the rain and at least 3.5 m away from the
pool. In the event of tripping the residual current device, check system integrity before resetting.
In case of doubt, contact a professional.
The salt chlorinator must be plugged into an outlet located in a well-ventilated area to prevent
overheating.
Do not install in places where water can easily ingress to prevent damage to the electrical
components caused by humidity or rain. A wall or oor mounting bracket is available as an
optional extra (ref.: CL-TSLFIX)
