Corrosion Protection; Thermostat For Feed Pump - Austria Email GTS 120 Bedienungsanleitung

If especially aggressive water is present which requires installation-side special solutions, the possible necessity of special
versions of the water heater should also be considered (ask one of our representatives or contact us directly).
Non-observance of this specification may be considered improper use and result in voiding of the warranty.
This device is not designed to be used by persons (including children) with physical, sensory or mental disabilities or lacking
experience and/or lacking knowledge, unless these are supervised by a person who is responsible for their safety or have
received instructions on how to use this device from any such person. Children should be supervised in order to ensure that
they do not play with this device.
The operator of the system must ensure that there is no hazard to persons from spraying with hot water, especially when
non-trained persons use the appliance.

7. CORROSION PROTECTION

The enamelled boiler is protected by a magnesium rod-type anode as standard. The magnesium rod-type anode is sacrificial
and must therefore be inspected every 2 years (see DIN 4753) and replaced as necessary (2/3 of the material). The degra-
dation products of the magnesium anode can precipitate as dissolved matter in the bottom area of the tank and also be
rinsed out from the tank during the water withdrawal. For the anodes to function properly, the water requires a minimum
conductivity of 150 μS/cm.
When retrofitting an external current anode, ensure that all magnesium rod-type anodes (e.g. in built-in heater) are removed
to prevent interference and malfunctions of the external current anode.
See Point 12, Par. C for details on servicing the anode.
The impressed current anode has a virtually unlimited service life. Its function must be regularly monitored via the control
lights (green, yellow, red).
Warning: If the red LED is lit, no corrosion protection is active! Corrosion protection is only guaranteed if the green LED lights
up continuously.
Should the red or yellow LED light up or flash, please inform Customer Services immediately.
The connection cable of the impressed current anode may in no case be extended or cut, because otherwise a possible
polarity reversal or malfunction of the anode may occur. In addition, it is to be ensured that a permanent power supply is
ensured.
Important: All metallic components must be introduced in a manner that is electrically isolated from the tank.

8. THERMOSTAT FOR FEED PUMP

When installing external thermostats, ensure that the boiler temperature cannot rise above 95°C during normal operation.
