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 be entitled to any claims for warranty, as provided, the installed reactive anode
requires documented inspection by an expert in intervals of maximum 2 years of operation.
Practically, the external current anode has an unlimited service life. Its function must be
monitored regularly by means of the control lamp.
This indicates two operating conditions:
Green: system ok
Red, flashing: malfunction - call customer service!
Pre-requisite for flawless functioning is that the tank is filled with water. For proper functioning
of the external current anode, a conductivity of the medium of >150μs/cm is required.

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.
