6. Checking, maintenance, care

The boiler scale as well as the furring that forms in the internal boiler of the storage tank in the case of
heavily calciferous water must be removed by an expert after one to two years of operation. The cleaning
is performed through the flange opening – de-install the built-in heater, clean the storage tank, use a new
seal when mounting the heating flange.
The internal tank of the water heater with special enamelling must not get in contact with boiler scale
solvents – do not use an antiliming pump.
Finally, the device must be rinsed thoroughly and the heating process be observed in the same way as
during the first commissioning.
In order to make a legitimate claim under the guarantee provided by the manufacturer, the in-built protecti-
ve anode requires a documented inspection by a specialist at a maximum interval of two years of operation.
For service work, it is also appropriate to open the cleaning and service flange, in order to check the tank for
the possible ingress of foreign bodies and impurities and to remove them if necessary.
The impressed current anode has a virtually unlimited service life. Its function must be regularly monitored
via the control lights (green, yellow, red).
Warning: 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 - corrosion
protection is not active!
A prerequisite for perfect functioning is that the container be filled with water and display a conductivity
of at least 150 µs/cm.
The guard circuit shunt resistor must not be damaged or removed during maintenance works.
Do not use any abrasive cleaning agents and paint thinners (such as nitro, trichlor etc.) to clean the device.
The best cleaning method is to use a damp cloth added with a few drops of a liquid household cleaner.
In hospitals and other public buildings, the prevailing regulations for cleaning and disinfection must be
observed.
During servicing works, it is advisable to open the cleaning and servicing flange in order to inspect the
tank for any foreign objects that may have been washed in as well as any contamination, and to remove
any such, if applicable.

7. Malfunctions

If the water in the tank is not heated, please check whether the circuit-breaker (MCB) in the distributor or
the fuse has tripped. Also check the setting of the temperature controller.
Please do not attempt to repair the defect in any other case. Either contact a licensed electrician or call our
customer service department. A skilled person can often repair the unit in no time at all. When you call us
to notify us of a defect, please always quote the type name and fabrication number, which you can look up
on the rating plate of your fitted heater.
