8. 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 degrada-
tion 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 conduc-
tivity of 150 µs.
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 external current anode has a virtually unlimited service life. Its function must be checked regularly via the control lamp.
The lamp indicates two operating conditions:
Green: Everything is OK.
Flashing red: Fault, contact customer service!
The connection cables of the external current anode may not be extended or cut under any circumstances, as this could result
in reverse polarity or malfunctions of the anode. Ensure also that a continuous power supply is guaranteed.

9. TEMPERATURE INDICATOR, THERMOSTAT FOR FEED PUMP

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

10. INITIAL STARTUP

The area in which the appliance is operated must be kept below freezing.
Initial startup and heating must be monitored by a technician.
Before first starting up and connecting to the electrical mains, the tank must be filled with water. When first filled the outlet
valve on the fitting must be opened. The water heater is completely filled when water runs out of the outlet valve with no
air bubbles. All connections, including those made on the user side (flange, anode sleeve,...) must be checked for proper
sealing when starting up. Then check the pipelines for any leakage and remedy this as needed. As described under 2. above,
the safety group as well as the valves between cold water inlet and water heater must be checked for proper function. After
inspecting the electrical fuses (circuit breakers), turn the thermostat knob (for electric upright and horizontal water heaters)
to the desired temperature setting and check for the correct temperature shut-off.
After the tank is fully heated, the set temperature, the actual temperature of the water removed and any built in temperature
indicator must closely agree (after deducting the switching hysteresis and line losses).
As the water in the tank is heated, its volume changes.
During the heat-up cycle the resulting expansion water in the internal boiler must drip from the safety valve. This dripping is
normal and may not be defeated by increased tightening of the valves.
Check for automatic shut-off of the system and any attached electric heater insert or the boiler.
Caution: The hot water outlet pipe as well as parts of the safety fitting can become hot to the touch.
