"!$& &The ProTech anti-corrosion system MUST be permanently
connected to a fused non-switched 240V electricity supply.
The ProTech system, an exclusive solution, is an electronic anti-corrosion
protection system which ensures maximum longevity of the appliance. The
electronic circuit creates a difference in potential between the hot water tank
and the titanium electrode, thereby guaranteeing optimum protection of the
tank and preventing corrosion.
Note: Do not use a water softner on products with the ProTech anti-
corrosion system.

prevent risk to the appliance’s lifespan when disconnecting the protection
system for an extended period of time, it is necessary to drain the appliance
beforehand.
In addition to the 240V network, the electronic circuit is also connected to
the tank, which is to be protected, and to the titanium protection electrode,

Proper operation of the protection system is shown by a continuous green
L.E.D, indicating that the circuits terminals are being supplied with electricity.
In the event of failure, a red LED indicates that there is a short-circuit
between the electrode and the cylinder tank, that one of the leads (tank or
electrode) is disconnected or that there is no water in the cylinder.
Your appliance is thus properly protected when the green L.E.D. is
illuminated and the red LED is off. Should this not be the case or should the
green and red LED light simultaneously, please contact your installer.
