2.- INSTALLATION INSTRUCTIONS
Recommended installation diagram[models D-10+ ... D-25+]
Recommended installation diagram [models D-40(+), see next page.
2.1. POWER SUPPLY
Always install the POWER SUPPLY of the IDEGIS system VERTICALLY on a solid and rigid
surface (wall) as shown in the recommended installation diagram. The POWER SUPPLY
should be installed in a well-ventilated dry place. The POWER SUPPLY should not be
installed outdoors, and should be installed a bit distant from the electrolysis cell so that it
cannot accidentally suffer water splashes.
Beware of corrosive atmosphere formation due to pH decreasing solutions (specially, those
ones based on hydrochloric acid "HCl". Do not install the IDEGIS SYSTEM near to any stores
of these chemicals. We strongly recommend the use of chemicals based on sodium
bisulphate or diluted sulphuric acid.
Power supply must be connected to the electrical control box of the pool, so that the pump
and the IDEGIS SYSTEM are turned on (and off) simultaneously.

2.2. ELECTROLYSIS CELL
The electrolysis cell is made of a transparent polymer in whose interior the electrodes are
placed. The electrolysis cell must be always installed indoors and after the pool filter, and
after any heating equipment that may be present (heat pumps, oil boilers, etc.).
The installation of the cell should allow easy access to the installed electrodes by the user. It
is highly recommended to install the electrolysis cell VERTICALLY [models D-10+ ... D-25+]
or HORIZONTALLY [model D-40(+)], in a place of the pipe that can be easily isolated from
the rest of the installation by two valves, so that the tasks of maintenance can be carried out
with no need of partial or total draining of the swimming pool.
Where the cell is installed on a by-pass (recommended option), a valve to regulate the flow
must be introduced. Prior to installation, please consider the following commentaries might be
considered:
oFlow direction marked in the cell must be
respected.
oRecirculation system must guarantee the
minimum flow stated in the Table of
TECHNICAL SPECIFICATIONS for each
model (see Section 1.3).
oThe system flow detector (1) activates if there
is not recirculation (flow) of water through the
cell or if flow is very low. If electrolysis gases
are not properly removed through the
electrolysis cell, the generated gas bubble
electrically isolates the auxiliary electrode
(electronic detection). Therefore, when
locating the electrodes in the cell, the level
probe (auxiliary electrode) will have to be
located in the higher area of the cell. The
safest orientation is shown in the
recommended installation diagram. In order to
avoid an excessive vibration of the electrodes,
these will have to be arranged inside the cell in
parallel to the water flow (2).
8

•WARNING : if the in-out valves of the electrolysis cell are closed simultaneously, the flow
detector will not work correctly, with the consequent risk of cell breakdown. Although this
situation is extremely unusual, it can be easily avoided once the equipment has been installed,
by locking at opened position the return valve to the swimming pool, so it cannot accidentally
be manipulated.
Other installations would only be acceptable if the detection of low or null flow is also allowed.
RECOMMENDED ACCEPTABLE (NOT RECOMMENDED)
Not acceptable installations

2.3. PH/ORP ELECTRODES
Install the pH electrode holders in the
circuit through ½” saddles (not
included with the equipment). Insert
the electrodes into their corresponding
holders. Next, tighten the holder until
the electrode is properly fixed
The electrodes must be installed in the
holder so that it is guaranteed that the
sensor located in their ends are always
submerged in the water circulating
through the pipe.
Install always the electrodes vertically
or with a maximum inclination of 40º.
2.4. ELECTRICAL CONNECTIONS
Check all the electrical connectors are well tightened to avoid false contacts and their
consequent overheating. Make the interconnection between the electrolysis cell and the
power supply according to the following scheme.
D-10+ D-18+/D-25+
10

D-40(+)
Connect the electrodes to the BNC connector in the right side of the unit.
IMPORTANT: due to relatively high current intensity
circulating do not modify or cut either the length or
section of the supplied cables without making a
previous consultation to an authorized IDEGIS
distributor. The connection cable cell-power supply
must necessarily be of the section recommended in this
Manual (see Section 1.2).

3.- SYSTEM DESCRIPTION
When an IDEGIS SALT ELECTROLYSIS SYSTEM is installed, a quantity of salt is dissolved
into the swimming pool water. This salty water then passes through the electrolysis cell that
is located in the plant room.
When a weak electrical current is passed through the plates inside the electrolysis cell,
chlorine is produced. Maintaining a level of chlorine in swimming pool water keeps the water
sanitised and healthy to swim in.
An IDEGIS SALT ELECTROLYSIS SYSTEM will manufacture chlorine whenever the pool
circulation system (pump and filter) is operational.
The IDEGIS SYSTEM will also monitor the pH and activate a dosing pump to add pH
reducing chemical if necessary. Moreover, the integrated ORP controller will automatically
control the chlorine level in the water, connecting/disconnecting the electrolysis system when
necessary.
It is important to continue to test the pool water for chlorine, pH and Total Alkalinity, and to
adjust these values as required. The chlorine level can be increased via the integrated ORP
controller. The pH will be reduced by IDEGIS SALT ELECTROLYSIS SYSTEM with
INTEGRATED pH/ORP CONTROL, and water balance must be maintained and adjusted
separately.
The IDEGIS SALT ELECTROLYSIS SYSTEM consists of two elements: an electrolysis cell
and a power supply. The electrolysis cell contains a quantity of titanium plates (electrodes), a
weak electrical current is passed through these plates and when a salt solution passes
though the cell, free chlorine is produced.
The power supply is provided with various safety devices, which are activated in case of
irregular operation of the system, as well as a microprocessor driven control system.
IDEGIS SALT ELECTROLYSIS SYSTEMS have an automatic cleaning system that avoids
scale formation on the electrodes.

4.- START-UP
Check that the filter is 100% clean, and ensure that the swimming pool and the installation
do not contain copper, iron or algae. Ensure that any heating equipment on the pool is
suitable for use in salt water.
Ensure that the swimming pool water is balanced. Balanced water enables the chlorine
that is produced to be used more efficiently and effectively, and ensures that the life of the
electrodes is prolonged. Water should be maintained within the parameters shown below:
a) pH must be in the range 7.2-7.6
b) Total alkalinity must be in the range 80-120 ppm.
Using a salt (sodium chloride) test kit verify that the minimum salt level in the water is 5 g/l
(5000 ppm). To obtain 5 g/l of salt in fresh water (that did not contain salt previously), add 5
kg of salt for every m3 (1m3 = 1000 litres = 220 gallons) of water. Always use common salt
(sodium chloride), without additives like iodides, that is “apt for human consumption”. Never
add the salt through the cell. Add it directly to the swimming pool or into the balance tank.
When adding the salt, and in case the swimming pool is going to be used immediately,
carry out a treatment with chlorine. An initial dose of 2 g/m3 of trichloroisocyanuric acid may
be added.
Prior to starting up the salt chlorinator, disconnect the power supply to the salt chlorinator
and run the pump for 24 hours to ensure that the salt is completely dissolved.
Next, reconnect the power supply and turn on the salt chlorinator, locating the production
level so that free chlorine concentration stays within the recommended range (0.5 – 1.5 ppm).
NOTE: in order to establish the free chlorine level you will need to use a test kit.
In outdoor swimming pools it is advisable to maintain a level of 20-25 g/m3 of chlorine
stabiliser (cyanuric acid) in the pool. A level of 75 ppm should be never exceeded. This will
help to stop the chlorine that is in the water from being destroyed by the sun.
