The ProTech system, an exclusive solution, is an electronic anti-corrosion
protection system which ensures maximum longevity of the appliance,
regardless of water quality. 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.
To ensure the proper operation of the protection system, IT MUST BE
PERMANENTLY CONNECTED TO A 240V, 3A ELECTRICITY SUPPLY
even in the event of shut-down of the system. To 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,
