b) If the water is very hard, a professional must remove the limescale forming inside the interior tank as
well as the freely deposited limescale after one to two years of operation.
For cleaning, it is necessary to open the flange – remove heating flange, clean storage tank, always use
a new sealing when refitting the heating flange. Any contact between the specially enamelled interior
tank of the water heater and boiler scale dissolver must be avoided – do not work with the deliming
pump. Scrape off deposited scale with wood and remove with a hoover or wipe with a cloth.
Finally, flush the device thoroughly (according to ÖNORM H5195) and observe the heating procedure
as if the device was first-time commissioned.
c) To make a justified claim under the warranty granted, the fitted protective anode must be checked by
a professional at max. 2-year intervals. Do not damage or remove the protective current discharge re-
sistor underneath the heater fastening screw during maintenance work.
d) Do not use abrasive cleaning agent and no paint thinners (such as nitro, trichlor compounds etc.) to
clean the device. It is best to clean the device with a moist cloth, adding a few drops of a household
cleaning liquid. In hospitals and other public buildings, the prevailing regulations for cleaning and disin-
fection must be observed.
MALFUNCTIONS
If the water in the storage tank is not heated, please check whether the circuit breaker in the distributor
(MCB) has tripped or whether the fuse has blown. Also check the setting of the temperature controller.
In all other cases, do not attempt to repair the malfunction yourself. Please contact either a licensed instal-
lation professional or our customer service. Often, a professional will be able to fix the storage tank in the
blink of an eye. When making your call, please always state the type designation and the serial number.
You will find it on the rating plate of your electric storage tank.
