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)

BEFORE USE
Adding salt
IMPORTANT: Before adding salt, ALWAYS perform a test to measure the
pre-existing salt levels (test strips or electronic tester).
Only use salt which complies with European standard EN 16401 to extend
service life and improve e󰀩ciency of the chlorinator cell.
DO NOT ADD chemical products or salt directly into the skimmer. This can damage the
cell. If the chlorinator cell has already been installed, do not switch on before adding salt
and ensure salt is completely dissolved.
When adding salt, it's preferable to pour the salt into the deepest part of the pool and then
switch on the lter pump to circulate the water and dissolve the salt (the cell must remain switched
o󰀨 during this time).
In summer, salt may take 24 - 48 hours to dissolve, and even longer in winter.
Do no place the plastic bag of salt into the water as the chemicals and inks on the bag can
interfere with water balance. Make an opening in the bag, then empty its contents. Once the bag
is empty, dispose in an appropriate receptacle or recycle if possible.
Required salt levels
The system can operate in a wide range of salinities, from a minimum of 2,700 ppm (parts per
million) up to 4,500 ppm. However, optimal salt concentration is around 3,000 ppm.
To achieve this salinity level, add around 3 kg of salt per 1 m3 of water (or 25 pounds of salt per
1,000 gallons of water).
TIP: When adding large quantities of salt, always start by testing the salinity of
the water and gradually adding salt, testing the concentration each time.
If you're unsure of the volume of your pool (m3), you can calculate it using the following equations:
Rectangular pool: Length x Width x Average Depth
Round pool: Diameter x Diameter x Average Depth x 0.80
Oval pool: Length x Width x Average Depth x 0.90
Before adding salt, test your water to measure salt concentration, then add the corresponding
quantities according the table below (next page).
If not enough salt is added, e󰀩ciency is reduced and the level of chlorine production will be too
low.
In addition, operating at low salinity levels will reduce the longevity of the cell. The salt in your
pool is constantly recycled, limiting the amount of salt lost during a bathing session. Losses are
mainly due to the addition of extra water replacing water lost as a result of splashes, run-o󰀨, lter
cleaning and drainage.
Salt is not lost through evaporation.
IMPORTANT:
In the event of excess salinity (> 4.5 g/l), partial emptying of the pool may be
necessary in order to add fresh water.

14
USE
Selecting operating modes
IMPORTANT: The chlorinator will only function when water ow is detected, i.e., when the
ltration system is switched on. Filtration time must therefore be su󰀩ciently long for the
selected operating mode (preferably one time slot per day during periods of strong sunlight).
Reminder: use the following formula to determine the best setting Filtration time =
(T° water)/2
1- Covered Pool Mode (or o󰀨-season)
- When covering your pool for more than 3 days, select Covered Pool mode (CO). The
chlorinator will only produce chlorine for 2 hours per day.
Chlorine production must be reduced if your pool remains covered for prolonged periods to
avoid overproduction. Covered pools are less exposed to organic materials (bacteria, cells),
UV rays and other sources of light. As a result, hypochlorite will convert back to salt more slowly.
Overproduction can lead to increased corrosion of the exposed metal surfaces of your pool.
- During the o󰀨-season, when water temperatures are higher than 10°C, but do not exceed 20°C,
select the Covered Pool (CO) mode. The chlorinator will only produce chlorine for 2 hours per day.
2- Spring Mode
At the start of the season, when water temperatures are higher than 20°C, but do not
exceed 25°C (i.e. a recommended ltration time of between 10h and 12h), select Spring
mode (P4). The chlorinator will produce chlorine for 4 hours per day. Below 10°C, the
chlorinator will not function and will display the following error code: E7.
3- Summer Mode
During the regular season, when water temperatures are higher than 25°C, but do not
exceed 28°C (i.e., a recommended ltration time of between 12h and 16h), select Summer
mode (P6). The chlorinator will produce chlorine for 6 hours per day.
4- Comfort Mode
During the peak of the season, or if you heat your pool, when water temperatures are higher
than 28°C (i.e., a recommended ltration time of between 16h and 24h), select Comfort
mode (P8). The chlorinator will produce chlorine for 8 hours per day.
5- BOOST 1 mode
Above these temperatures, during periods of hot weather with water temperature exceeding
30°C (i.e., a recommended ltration time of 24h), or following heavy rainfall, it may be
necessary to increase hypochlorite production for a limited period of time. Select BOOST
1 mode (B1). The chlorinator will produce chlorine for 12h over the course of the day and
revert to Comfort Mode (P8) the following day.
6- BOOST 2 mode
During periods of extremely hot weather, with water temperatures exceeding 30°C (i.e.,
a recommended ltration time of 24h), and/or with intensive use of the pool, it may be
necessary to produce even more chlorine for a limited period of time. Select BOOST 2 mode
(B2). The chlorinator will produce chlorine for 24h over the course of the day and revert to
Comfort Mode (P8) the following day.
These are preset modes and will restart daily at their selected time. Depending
on the usage and conditions of your pool (volume, exposure to plant material,
sunlight, etc.), it may be necessary switch to a higher or lower mode.

15
TROUBLESHOOTING
WARNING: If the water has turned green after winterizing your pool, or during periods of
extremely high temperatures, the chlorinator alone will not be su󰀩cient to clear up green
water. Intermittent use of chlorine tablets may be necessary. Do not put the chlorine tablets
directly into the skimmer; use a oating dispenser. If you need to use a chlorine shock
treatment, switch o󰀨 the chlorinator beforehand to prevent damage to the cell.
Performing system checks
Even though we take every necessary precaution when manufacturing the chlorinator,
breakdowns are still possible. In the event of a defect and/or malfunction, electrical power must
be switched o󰀨 and no attempts to repair the fault should be made. Repairs must be carried out
by an authorised technician using original spare parts. Not complying with the aforementioned
clauses can negatively impact the safe operation of the chlorinator.
However, other underlying factors may also a󰀨ect the treatment e󰀩ciency of the chlorinator, such
as issues with water quality (water starting to turn green); please follow the steps below to help
with troubleshooting.
Here are some steps to take in order to verify if your chlorinator is malfunctioning:
Check that it is plugged in
Check that the power is still on and if the residual current device has tripped (or the upstream
circuit breaker); in case of doubt, contact a professional.
Check that the ltration time is su󰀩ciency long: Filtration time = (T° water)/2
To obtain optimal treatment, we recommend selecting the appropriate mode for the temperature
of your water, and to use the two BOOST modes in case of high temperatures and intensive use
(see section on selecting operating modes). These are preset modes and will restart daily at their
selected time. Depending on the usage and conditions of your pool (volume, exposure to plant
material, sunlight, etc.), it may be necessary switch to a higher or lower mode.
In addition, depending on the mode, the minimum daily ltration time must be
respected:

TROUBLESHOOTING
WARNING: If you split your daily ltration time into multiple time slots, we recommend
the slot used for treatment is su󰀩ciently long to cover the entire length of the treatment.
These are preset modes and will restart daily at their selected time.
Check that the parameters of the water are correct (salinity, stabiliser level, pH and if
necessary hardness and alkalinity)
Check that the water ow rate is su󰀩cient (> 2 m3) and/or not too high (< 10 m3)
If you are still encountering issues, your chlorinator may be malfunctioning. The chlorinator also
has a self-test function which will display error codes in the event of a problem (see next page).

TROUBLESHOOTING
Cleaning the cell
To maintain optimal performance of your chlorinator, the cell should be inspected at least once
every 3-4 months (there should be no debris obstructing the ow sensor or between the electrode
plates).
The cell has a self-cleaning function which uses reverse polarity. In most cases, this self-cleaning
function will keep the cell operating e󰀩ciently and will prevent formation of scale deposits.
The cell should be cleaned once or twice per season.
In areas where the water is very hard (i.e., high calcium concentration), or in pools with poorly
balanced water, the cell may require additional cleaning. Remember to set your reverse polarity
time (4h / 8h / 12h) according to your water hardness. As water hardness increases, the time
should decrease.
This chlorination process which creates chlorine (hypochlorite) from salt naturally leads to the
formation of mineral deposits on the titanium electrodes of the cell. The reverse polarity self-
cleaning function helps prevent these deposits and scale formation. If the water is very hard, with
a high degree of general hardness, the formation of deposits is inevitable and these deposits must
be removed.
To clean the cell:
Disassembly:
Shut o󰀨 the power supply and close any return valves.
Unplug the power cable from the transformer.
Unscrew the threaded nuts around the PVC connectors which connect the cell to the piping.
Remove any residual water (drain into a receptacle and put it back into the pool).
Completely remove the union ttings from the cell. DO NOT pull or carry the cell by its power
cable.
Attention: unscrewing the grey mounting nut from the control box will void the warranty.
Cleaning:
Always use a descaling agent intended for use in a salt chlorinator cell; follow the instructions and
safety recommendations of the manufacturer.
Follow the steps below to disassemble the cell:
Using a pipe end cap (e.g. product ref. CL-TSLCAP - provided), plug one
opening and hold the cell upright, with the end cap at the bottom.
Pour the desclaing agent directly into the cell until it covers all of the
deposits.
Once the electrode plates have been completely submerged, wait 10 to 20
minutes (depending on the brand and quantity of scaling to be removed), periodically agitating the
liquid in the cell.
Check that all scale deposits have been removed. Perform these steps again if necessary.
Once all scale deposits have been removed, rinse and reassemble the cell.
Using an inappropriate or highly concentrated product (pure acid) can cause visible and
irreversible damage to the cell not covered by the warranty and could be potentially dangerous.
When cleaning the cell, always wear appropriate protective equipment such as rubber
gloves and eye protection.
Always work in a well-ventilated area. Acid splashes can lead to serious injury and/or
property damage.
Never add water to acid.

Replacing the cell
Once the titanium plates inside the chlorinator cell have reached the end of their service life
(after around 10,000h), they can be replaced. To guarantee quality and value, only use original
spare parts. If necessary, bypass tubes can be used to allow water to continue circulating in the
pipework once the cell has been removed. See chapter on winterizing (Winterizing tube product
ref. CL-TSLTUBE)
WINTERIZING
Active winterizing
When temperatures are low, very little chlorine is required. If actively winterizing your pool, the
Covered Pool mode will be su󰀩cient.
However, the chlorinator will not produce chlorine below 10°C and will display an error code (E2);
this feature prolongs the service life of the cell.
If water temperature continues to decrease until freezing, the cell and plumbing of your pool will
be damaged by the freezing water.
Before rst frost, as a precautionary measure, disconnect the cell (following the steps above) by
closing the bypass to isolate the circuit. Store your cell in a dry place.
If a bypass is not in place, replace the cell with the winterizing tube (product ref CL-TSLTUBE -
provided). Store your cell in a dry place.
Passive winterizing
In areas subject to periods of prolonged or extreme cold, before rst frost, ensure that all water
has been removed from the pump, lter, as well as the water
supply and return lines.
As a precautionary measure, disconnect the cell (following the
steps above) by closing the bypass to isolate the circuit and store
your cell in a dry place.
If a bypass is not in place, replace the cell with the winterizing
tube (product ref CL-TSLTUBE - provided). Store your cell in a
dry place.
Restarting in spring
When operating pool equipment for the rst time after long periods of inactivity, do not switch on
the chlorinator until the water has been balanced, in particular pH and salt concentration, and
optimal levels have been reached (namely, pH between 7.0 and 7.4 and salt concentration of 3.5
g/l).
This is also a good time to test the other parameters mentioned at the beginning of this user
guide.
WARNING: If the water has turned green after winterizing your pool, or during
periods of extremely high temperatures, the chlorinator alone will not be
su󰀩cient to clear up green water. Intermittent use of chlorine tablets may be
necessary. Do not put the chlorine tablets directly into the skimmer; use a
oating dispenser.
If you need to use a chlorine shock treatment, switch o󰀨 the chlorinator
beforehand to prevent damage to the cell.

USEFUL TIPS
General principles
Correct operation of the chlorinator can be easily veried by checking the lights on the control
panel. However, if the pool remains cloudy and tests show low levels of residual chlorine, the
chlorine produced may have been lost due to high chlorine demand or improper water conditions.
To reduce chlorine demand:
Check pH levels (between 7.0 and 7.4)
Check stabiliser levels (Cyanuric Acid) are between 20 to 50 ppm
Check for the presence of phosphates and nitrates which increase overall chlorine demand
If these tests are positive, a oxidizer shock treatment is recommended.
In general, BOOST modes are not required if the pool is maintained at the correct levels.
List of Recommended Actions:
Read the manual and keep in a safe place for future reference.
Adjust chlorine production when temperatures increase or decrease (select the right mode).
Increase chlorine production when bathing load increases (see BOOST modes).
Use a stabiliser (Cyanuric Acid) at concentrations of 20 to 50 ppm to protect the free chlorine in
the pool.
Where possible, install the chlorinator out of direct sunlight.
Regularly get a water sample tested by a qualied pool professional.
Maintain salt concentration levels around 3.5 g/l (3,500 ppm).
Regularly test the parameters of the water.
List of Prohibited Actions:
Do not use fertiliser close to your pool. Fertilisers are an abundant source of Nitrates and
Phosphates, resulting in higher chlorine demand and deposits on the chlorinator cell.
Never use pure acid to adjust the pH. Deposits of by-products can damage the cell.
Do not add any chemicals to the water (including salt) when the chlorinator is switched on (switch
it OFF).
Do not add chemicals (including salt) directly into the skimmer.
Do not allow salinity to fall below 3 g/l (3,000 ppm).
SUPPLEMENTARY ELECTRICAL BONDING (POOL EARTHING)
In order to protect the metal components (including stainless steel) in contact with the water
of your pool, it is strongly recommended to install supplementary bonding (POOL EARTHING)
(product ref. CL-POOLTERRE50 - supplied) which is separate from the earthing system of your
house in order to carry residual current from your pool equipment to the ground. This current can
lead to serious galvanic corrosion. (Ground cable not supplied)
