Safety Recommendations; User Safety; Safety Of Materials And Premises - BWT EES Notice De Montage

The electrolysis of chlorides at the anodes is accompanied by the formation of sodium hydroxide 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.

SAFETY RECOMMENDATIONS

2.1

User safety

The EES and EES Pro electrical/ control panel should be wired in by a qualified professional, according to
the standards in effect in the country of installation. It should be located at least 3.5 m from the pool.
Should this be impossible, it may be positioned closer than 3.5 metres, but not less than 2 m from the
pool (the control panel has a protection rating of IP56, against splashing), subject to the condition that the
power cable is connected directly to a 30 mA residual circuit device.
Never remove the cover protecting the electrical panel connection terminals while the electrical panel is
energised. Always cut the power supply to the electrical panel beforehand. The cover should be replaced
immediately after the intervention.
In the event of damage to the power cable, have it replaced immediately by a professional.
Locate the electrical/ control panel high enough to be out of the reach of children.
!
The electrolyser cell is powered by a 12V direct current supply from the electrical/ control
panel. There is therefore no electrical risks to bathers using the pool while the device is in
operation.
Safety recommendations concerning the acid dosing pump:
The acid dosing pump aspirates and injects concentrated acid into the hydraulic circuit.
When handling acid, and during interventions on the pump or its tubing, protective glasses and clothing
should be worn to protect against splashes. In the event of contact with the skin, flush the area abundantly
with water, seek medical attention immediately if the eyes are effected.
Check the condition of the tubing through which the acid flows regularly and replace it immediately if it
appears worn or damaged or is leaking.
2.2

Safety of materials and premises

The electrical/ control panel power cable must be protected by a suitably rated thermo magnetic circuit
breaker.
Never operate the device by electrically bypassing the flow sensor. If no water is flowing through the cell,
there is a risk that inflammable vapours could accumulate in the pool's hydraulic circuit.
Never operate the device while the hydraulic circuit upstream and downstream from the device is blocked.
Vapours accumulating in the cell could cause an overpressure leading to the rupture of the cell.
