: The ProTech anti-corrosion system MUST be permanently

MportAnt

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.

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,

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.

Direct systeMs

A mains supply of 240V, 3kW (13 amps) is required. Heat resistant cable,

round 3 or 4 core 2.5mm

(to BS6141 table 8) must be used to connect the

electrical supply through the Economy 7 time control switch using either

system 'A' or 'B' as illustrated in Fig. 3.12.
