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 FUSED NON-SWITCHED 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,
INFORMATION FOR THE END USER
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 L.E.D. 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 L.E.D. Is off. Should this not be the case, please
contact your installer.
