4. INTRODUCTION
Emaux SSCmini® is an automatic chlorine generation system for pool sanitization and it is composed by two
main components: an electrolytic cell and a control unit.
4.1 ELECTROLYTIC CELL
The electrolytic cell is composed by a number of titanium plates (electrodes) placed in a cell holder. The
control unit regulates electrical current that passes through the titanium plates. One extreme of the plates
will be anode and the other will be cathode.
Adding a certain concentration of salt in the water, this passes through the plates and thanks to the
electrical current, the Hypochlorous acid is produced.
The following chemical reactions are produced in the plates of the electrolytic cell:
Positive pole (anode): 2 H2O O2 + 4 H+ + 4e
-
2 NaCl Cl2 + 2 Na+ + 2eNegative pole (cathode): 2 H2O + 2e- H2 + OHFinal chemical reaction: Cl2 + OH- HClO + Cl-
The operation requires a certain concentration of salt (4000 ppm), low enough that it normally will not
be tasted. The SSCmini® automatically sanitizes your pool by converting the salt into Hypochlorous acid
which kills bacteria and algae in the pool through a process called electrolysis.
Because chlorine will revert back to sodium chloride after killing the bacteria, the above reactions will
continuously recycle virtually eliminating the need to add sanitizing chemicals to your pool. The only time
you may need to add more salt to the pool is when water is replenished due to backwashing, draining,
or splashing.
4.2 CONTROL UNIT
The control unit is provided with a microprocessor driven control system to regulate operation time and
inform about SSCmini® operation status and errors. The system also includes a self-cleaning procedure
that avoids scale formation on the electrodes.
5. SAFETY WARNING AND RECOMMENDATIONS
The equipment should be assembled and handled by truly qualified people.
Current electrical and accident prevention regulations should be followed.
Under no circumstances will the manufacturer be held responsible for the assembly, installation or start-up,
nor any handling or fitting of components unless they are carried out on its premises.
The working voltage of SSCmini® is 220-240V, 50/60Hz. Do not attempt to alter the system to operate at
a different voltage.
Check all the electrical connectors to avoid false contacts and their consequent overheating.
Before installing and replacing any component, disconnect the control unit from the main power supply;
only replacements provided by Emaux can be used for replacing.
The control unit must be installed in places with sufficient ventilation. The equipment should not be installed
Page 4

near flammable materials.
This equipment should never be installed in places susceptible to flooding.
It is important to reduce chlorine production properly while the pool is covered. Otherwise, an excess of
chlorine could degrade the pool materials.
6. WATER CHEMISTRY
The following table shows the recommended levels of the chemical parameters required for a proper quality
of water in the pool by using Emaux SSCmini®.
Test your water periodically and ensure the levels are within the recommended range.
Salt Level
4000 – 6000 ppm
Free Chlorine
1.0 – 3.0 ppm
pH Value
7.2 – 7.6
Cyanuric Acid (stabilizer)
30 – 50 ppm
Total Alkalinity
80 – 120 ppm
Calcium Hardness
200 – 400 ppm
Metal
0 ppm
6.1 SALT LEVEL
The amount of salt required when using Emaux SSCmini® is between 4000 and 6000 ppm. To reach
this concentration, it is necessary to 4 kg of salt per each cubic meter of pool water.
Low salinity (below 2500ppm) will cause premature cell failure. High salinity (above 6000ppm) will result
in electro-oxidation and the corrosion of stainless steel swimming pool fixtures.

6.2 TYPE OF SALT
The most common salt used in swimming pools with Salt Electrolysis is Sodium Chlorine (NaCl) that is
99% pure. DO NOT use the following types of salts:
rock salt;
salt with more than 1% yellow prussiate of soda;
Salt with more than 1% of anti-caking additives;
Iodized salt.
6.3 ADDING AND REMOVING SALT
Before adding the salt into the pool, turn your filtration pump on and set your filtration valve manifold in
position “Filtration”. Add the salt directly into the pool or balance tank and do not allow the salt to sit in
a pile on the bottom of the pool. Keep the filtration system running for 24 hours using a main drain or a
vacuum suction nozzle as a main suction line.
The only way to remove the salt in the pool water is to partially drain the pool and refill with fresh water.
7. INSTALLATION
7.1 CONTROL UNIT INSTALLATION
The Emaux SSCmini® control unit is contained in a raintight enclosure that is suitable for outdoor
mounting (IPX4 rating). However, the following points must be taken into consideration for a correct
installation of the control unit:
1. Install the Control Unit using the mounting template provided with the package. The unit should be
installed in a minimum distance of 3 meters from the swimming pool, 1.5 meters from the ground,
within 2 meters from electrical enclosure, and within 3 meters from where the cell will be installed.
2. Fix the mounting template on the wall and drill 4 holes with a diameter of 8mm in the wall according
to the mounting template (Figure 1). Use expansion bolts to support the control unit.
3. Hang the control box on the fixed bolts (Figure 2) and make sure that the power cable and cell cable
also reach the Control Unit.
4. Don’t install the control unit under direct sun light.
5. The control unit should be installed away from chemicals storage.
6. The unit must be kept away from heat sources and any equipment which produce heat.
7. Plug-in power supply into a suitable weatherproof outlet socket with circuit breaker.

7.2 ELECTROLYTIC CELL INSTALLATION
Please follow the recommendations below to install the electrolytic cell properly:
1. The electrolytic cell should be mounted once the installation of all other swimming pool equipment
is completed (filtration pump, filter, heating system).
2. The electrolytic cell is designed to install in PVC pool plumbing. The opening of the cell holder must
be placed upright to enable the maintenance of titanium plates. To install the cell, cut off at least
187mm of pipe. Fix the electrolytic holder on the pipe, put the electrodes into the cell. Make the
electrode cable go through the nut (Figure 3).
3. Connect the unions to the pipe and make necessary adjustments for a proper connection. Once
adjusted, fix the connection with PVC glue and tighten the union nuts.
4. Fix the electrodes inside the holder and tighten the nut of the cell; connect the electrode cable to the
control unit; tighten the nut to ensure the good contact (Figure 4).
Note: the cell can also be installed in a vertical position.
8. START-UP
Before starting up Emaux SSCmini® unit, the following points have to be taken into consideration:
1. Check if the filter is completely clean, and ensure that the swimming pool and the installation do not
contain any metals dissolved or algae.
2. Ensure that the heating equipment (if any) is suitable for use in salt water.
3. Ensure that chemical parameters of pool water are within the recommended range (see Chapter 6).
4. Run your filtration system for 24 hours before starting salt chlorinator so that salt in the swimming pool
is completely dissolved.
For start-up, set the system at 50% of working time. It will take a few days of adjustments to find the most
appropriate setting according to the chlorine demand of your swimming pool. Once determined, only minor
adjustments might be necessary in cases of splashing, backwashing, rain, etc.
The temperature of the water is a parameter that effects the chlorine production. When the temperature rises,
chlorine will be easily volatilized affecting sanitizing effect. The water temperature should be within the range
of 15-40ºC. The Emaux SSCmini® will not produce chlorine at temperatures below 10º C.
Figure 4
Figure 3

The desired level of chlorine generation should be modified according the following parameters:
1. Pool water temperatures increases or decreases significantly
2. When there is a higher load of bather than normally
3. When the cell’s life time is finishing
4. In a long period of inactivity or winterizing
9. OPERATION
SSCmini® salt chlorinator is managed through a control panel that regulates chlorine production and
informs about operation status.
LED INDICATORS
1. Cell life low. Illuminates when the cell reaches the end of its expected life. In this case, the cell
electrodes have to be replaced.
2. No flow. Water flow is not detected, or water flow is too low. If operation schedule is not active, no

EXAMPLE
If you start SSCmini® at 9:00 and set the work schedule at 5, then the unit will be working from 9:00 to
9:30 (Normal operation LED is ON) and in stand-by mode from 9:30 to 10:00 (Stand-by LED is ON).
A new cycle will start at 10:00 until 10:30, and so on.
If you activate Superchlorination mode at 10:30 (Superchlorination LED is ON), then the unit will be
working until 10:30 of the next day and will exit Superchlorination mode afterwards. Once finished
Superchlorination, the schedule will be restored and a new cycle will start.

10. MAINTENANCE
Due to the Reverse Polarity system that avoids scale in the plates of the cell, the first action to consider for
ensuring a long cell lifetime is to keep the chemical parameters always in the recommended range, especially
the amount of salt, the pH and the water hardness.
1. Keep the salinity of the water always higher than 3000 ppm in order to avoid premature deterioration
of the cell plates. The following formula determines the amount of salt to be added in the pool due to low
salinity:
Q = (4-S) x V
Where Q = quantity of salt (kg) to be added.
4 = correct salt concentration (constant).
S = Measured salt content in the pool
V = Volume of the pool in m3.
2. Keep the pH between 7.2 and 7.6. Check and clean the cell plates if the system has been working for
a prolonged period with a pH value over 7.6.
ELECTROLYTIC CELL CLEANING PROCEDURE
If scale has formed on the titanium plates, the first cleaning procedure is as follows:
1. Switch off the power supply of SSCmini
®
control unit and remove electrodes from the cell.
2. Once removed, look inside and inspect for scale formation on the plates and for any debris which
has passed through the filter and caught on the plates.
3. Try to remove the scale using a plastic or wooden tool (do NOT use metal as this will scratch the
coating off the plates).
If the scale still remains on the plates, proceed the cell cleaning with acid solution:
1. Dilute hydrochloric acid with water: one part of acid in 10 parts of water.
ATTENTION! Always add acid into the water, NEVER add water into the acid. This prevents splashing
of the acid when the water hits it. Wear rubber gloves and appropriate eye protection.
2. Submerge the cell plates in the solution for no more than 10 minutes. Plates plastic housing can be
submerged in the solution, but avoid any contact with the cell connections and wires.
3. Rinse the cell with a high pressure hose. If any deposits are still visible, repeat soaking and rinsing.
4. If scaling persists, replace the cell by a new one.
11. WINTERIZING
During a long non-working period, such as winter, the following procedure must be carried out:
Switch off SSCmini
®
control unit and disconnect it from power supply.
Drain all water from the electrolytic cell, as well as filtration pump, filter and piping.
Clean the cell plates with fresh water and dry them with a soft cloth. Check if scaling has been
formed. If so, proceed with cleaning of the cell plates (see chapter 10).
