I. PRODUCT DESCRIPTION AND OPERATING INSTRUCTIONS:
EES and EES Pro are pool water treatment devices
that electrolyse salt (Sodium Chloride) dissolved in
the pool water.
dissolved in the pool water. The salt concentration
of sea water, this means that neither the perceived
chloride ions are transformed into free chlorine
at the electrodes connected to the positive
terminal of the electrical panel (the anodes). This
transformation is achieved through the circulation
of a SVLV (Safety Very Low Voltage) within the cell.
The active Chlorine (a fraction of which is
transformed into inactive Chlorine depending
on the pH) disinfects the pool water (kills micro-
organisms).
The production of active Chlorine by salt water
electrolysis causes a slow, gradual rise of the
water's pH, this must be compensated by the
regular addition of a suitable quantity of acid.
Two EES (Pro) models are available:
• for pools containing up to 80 m

There are two versions of each model: EES and

EES Pro differs from EES in that it regulates:
•
potential) in the pool water, only producing
Chlorine when necessary;
• the water's pH, by injecting acid into the hydraulic
circuit to lower the pH when necessary.
EES regulates neither free Chlorine nor the pH. It
produces Chlorine continuously as long as water

regularly and the pH will need to be adjusted when
necessary.

regulation. The pH Clear pump also descales the
The Product is installed in the pool plant house, it
comprises two main components:
• An electrical/ control panel that is mounted on
a vertical wall at a height inaccessible to young
children;
• An electrolysis cell that is mounted on a by-
pass loop on the hydraulic circuit after any other
The salt water electrolysis process offers many
advantages when compared to conventional
chlorination processes:
• No handling or storing of dangerous, concentrated
chlorinated products (salt is harmless and
chemically inert) ;
• No risk of over-stabilisation of the pool water;
• The process regularly produces active Chlorine,
this limits the formation of foul smelling chloramines
that irritate the bather's skin and eyes: bathing is
• The destruction of chloramines releases chlorides
that can be transformed into active Chlorine in the
cell. Chlorine is regenerated, limiting the amount
of salt that needs to be added over time;
The Pro model of the EES provides a
comprehensive pool water pH regulation and free
Chlorine regulation solution.
The electrolysis of chlorides at the anodes is
at the cathodes, this generates a very high pH
at the cathode that can cause the deposition of
limescale on the cathodes. To limit scaling, EES
and EES pro are equipped with a system that
switches electrode polarity at regular operating
intervals. The duration of the polarity inversion
cycle is controlled automatically by the device, it
may not be set by the user.
