1. SAFETY GUIDE

IMPORTANT: The instruction manual you are holding includes essential information on the safety
measures to be implemented for installation and start-up. Therefore, the installer as well as the
user must read the instructions before beginning installation and start-up.
Keep this manual for future reference.

When using this electrical equipment, basic safety measures listed below should be followed:

 Disconnect all AC power during installation.
 To reduce the risk of injury, do not permit children to use this product unless they are closely supervised.
 A green colored terminal marked "Earth Ground" is located inside the wiring compartment. To reduce

the risk of electric shock, this terminal must be connected to the grounding means provided in the
electric supply service panel with a continuous copper wire equivalent in size to the circuit conductors
supplying the equipment.

 To reduce the risk of electric shock, connect the local common bonding grid in the area of the swimming

pool or spa to these terminals with an insulated or bare copper conductor.

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

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.
