1. GENERAL RECOMMENDATIONS

For correct operation of the device:

Read this instruction manual carefully and completely before using your STERILOR Duo. Do not open

the device, only a skilled technician is authorised to do so.

Check the safety of the device: Make sure that the voltage supplied by your mains power supply

complies with the characteristics repeated in Paragraph 9.

The STERILOR Duo device must operate at the same time as the filtration system, because the water

must absolutely flow in the electrolysis cell.

When salt is added to the pool for the first time, or whenever salt is topped up, the STERILOR Duo

control box must be shut down for at least 24 hours until the salt has completely dissolved.

The device must be stopped as soon as the water temperature drops below 15°C.

In fact, at those temperatures, the titanium electrodes coated with precious metal oxides produce

more oxygen and hydrogen than chlorine.

Definition of the synoptics used in these instructions:

Important information

Sensitive point, recommendation to be followed to avoid any equipment deterioration

or operating problem.

Electrical risks, any operations relating to connections or tests may only be carried out

by accredited persons.

Earthing mandatory

2. PRESENTATION

2.1 General description

The STERILOR Duo can automatically

produce chlorine in the form of sodium

hypochlorite (bleach) by electrolysing salt

water containing between 4 and 5 gr / litre.

At the same time, it analyses the pH of

your water and regulates it automatically.

2.1.1 Operation of the Salt part

The STERILOR Duo automatic system

operates based on the principle of salt

water electrolysis.

Thanks to its microprocessor, STERILOR

Duo controls the emission of a low voltage

electric current towards an electrolysis cell

placed on the filtration circuit backflow

(after any analysis electrode as well as any

booster pump, heat pump, or heating

output).

This cell contains several electrodes made

of titanium and specially treated with

precious metal oxides, in order to

withstand changes in polarity of the

production current.

The pool water, which has a very low salt

content (4 to 5 g/l), passes into the

electrolysis cell and is transformed into

sodium hypochlorite (bleach), which is a

powerful steriliser.

The STERILOR Duo will allow you avoid

adding chlorinated products.

STERILOR Duo is compatible with all

current pool liners, and adapts to any

existing or new filtration systems.

Warning:

Salt is incompatible with metal filtration

systems.

When adding salt to the pool for the first

time or during each subsequent addition,

the STERILOR Duo box must be switched

off for at least 24 hours, and total

dissolution of the salt must be validated

before starting or restarting the device.

The advantages of STERILOR Duo:

•Automatic water treatment

•Sterilised and sterilising water

•A change of polarity in the production

current which reduces the formation of

scale on the electrodes

•Backlit digital display of the production

percentage, device operating times and

countdown of the change of polarity time

•A configurable Slow mode function for

swimming pools equipped with covers

•A device that can be adapted to all

swimming pools

2.1.2 Operation of the pH part

The automatic STERILOR Duo

system proportionally regulates the pH

using a peristaltic pump, and a control with

LCD screen display.

The advantages of STERILOR Duo:

•An automatic system for controlling correct

operation of the regulation unit, and if a

problem is detected, injection is stopped

immediately.

•pH analysis to the 100th of a unit

•Accurate proportional regulation based on

an adjustable pH threshold

•A simple, reliable and robust box

comprising the pump and the

measurement-regulation circuit

•A backlit digital display of the pH value

•A device that can be adapted to all

swimming pools

2.1.3 Supply

This device is supplied with all equipment

necessary for its installation and use. This
