PRESENTATION
How the unit works
The LIMPIDO 100 is a sterilising system which functions by electrolysis of salt water. The
Electrolytic process separates the salt present (NaCl) into sodium (Na) and chlorine
(Cl), which immediately dissolves in the water to make hypochlorous acid (HClO).
This is a powerful disinfectant which kills any bacteria and algae before changing
back into salt. The electrolyser only produces chlorine when the flowmeter detects
that water is circulating in the cell.
The electrolysis unit only produces chlorine during filtration periods determined by the
programming clock. During these filtration periods, the production time is composed
of cycles made up of two periods (Normal and Inverse) that alternate the polarity of
the electrodes. This polarity inversion avoids scaling of the electrodes. The duration of
each production cycle is about 2h00 and it is broken down as follows:

NOTICE TECHNIQUE V2 LIMPIDO-PRO
CCEI page 4
-Phase 1, normal production. (40 minutes).
-Phase 2, rest (20 minutes).
-Phase 3, inverse mode production. (40 minutes).
-Phase 4, rest (20 minutes).
Two operating modes may be chosen depending on how much chlorine you want to
produce (ppage 6), but in any case, your electrolysis unit should not be allowed to
operate unless the filtration is in service itself (see “flow detector” section), for safety
reasons.
Continuous mode (Manual operation):
In this mode, the LIMPIDO repeats its 2h00 production cycle throughout the entire
filtration period.
Programmed mode (Operation on the clock):
In this mode, the LIMPIDO only operates during the times programmed on its clock.
Its operating times within the periods determined for the filtration pump should be
defined (see example below).

10:00 and 16:00 and between between 10:00 and 12:00 and
18:00 and 21:00 18:00 and 20:00
At the end of a filtration period, the LIMPIDO also stops immediately (however its
clock continues normally) but its control box memorizes the position of the
electrolysis unit within the cycle, and the next time that a filtration period is started,
the LIMPIDO resumes its cycle at exactly the position at which it was interrupted.
The main advantage of this operating method is that it guarantees absolutely
identical normal and inverse production times in all cases (even in the case of a
power failure), and consequently assures the user that scale elimination in his unit
will be optimized (to guarantee production quality and durability of the
equipment).
The electrolytic cell
The cell is an essential element of the LIMPIDO and must be handled with care.
The cell is equipped with electrodes composed of solid titanium plates treated with
ruthenium oxide. It is specially designed to maximize life and to restrict maintenance
operations.
The Flowmeter
The flowmeter delivered with LIMPIDO 100 prevents the electrolyser from functioning
when water is not circulating and during back-washing. This prevents any build up of
hydrogen or overheating, ensuring the unit remains safe.

THE CONTROL BOX
The design of the control box is particularly robust with excellent waterproofing, and it
contains all control, instrumentation and safety elements included in the appliance.

The production indicator
The ammeter tis used to check the production level of the unit.
Production check
The measurement dial is divided into three parts (less than 4 amperes, 4 to 6 amperes,
more than 6 amperes), representing the production level.
Part Production Action
0 to 4 A Low Increase production using s, check the salt
content or clean the cell.
4 to 6 A Normal
6 to 10 A Excessive
overproduction
Reduce production using s
Excess salt - Check the salt content
The production level must be kept within the 4 to 6 A range at all times.
Production fault
In case of overproduction (current exceeding 6 A). This fault usually occurs if there is
too much salt in the pool.
The control box is equipped with a rated circuit breaker uthat cuts off production in
the case of overproduction, so that the cell cannot be damaged by an overcurrent.
This fault is cleared by waiting for a few minutes to allow the unit to cool, and then
resetting uand reducing production using switch suntil the needle returns to the
central part of the indicator. If the unit overproduces because there is too much salt,
replace some of the water in the pool until the salt content is acceptable.
Checking the salt content
The salt content in the pool must not drop below 2g/l when the water temperature is
25°C. It is recommended that the salt content should be kept between 2.5g/l and
4.5g/l to protect the electrolysis cell. The water conductivity varies with the
temperature. The salt content should be kept above 3.5 g if LIMPIDO is to operate in
water below 18°C.

NOTICE TECHNIQUE V2 LIMPIDO-PRO

Use the salt tester supplied with the LIMPIDO to check that the salt content is correct.
Please refer to the tester instructions before use.

Installing the flow detector
Glue (PVC glue) the 25/¾" nipple into the 50/50/25 Tee, before installing the flow
detector.
Wait until it is completely dry, and then screw in the detector, fitting the supplied 20/27
seal onto it.
Do not overtighten the detector.

Installing the Pool Terre®
The Pool-terre device is necessary to carry electrostatic charges contained in the
water to earth.
When it is connected to an earthing terminal, this device eliminates leakage currents
and reduces oxidation and reduction phenomena responsible for corrosion.
•Install the 50/50/1/2" Tee on the discharge pipe on the downstream side of the
heating or electrolysis equipment.
•Connect the Pool-terre to the equipotential pipe, giving priority to a direct
connection to the earthing rod and using a green and yellow cable with
appropriate cross-section (not less than 16mm²).
