A conductivity value of the medium of ≥ 150 μS/cm is necessary for proper functioning of the external current
anode.
d) 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.
e) The tank can be used exclusively in accordance with the conditions specified on the rating plate. Aside from
the legally approved national regulations and standards, the connecting requirements of the local power com-
pany and waterworks, as well as the Assembly and Operating Instructions must be complied with.
f ) The room in which the device is operated must be free of frost. The assembly must be performed at a locati-
on that is reasonably to be expected, i.e. it must be possible to access the unit without any difficulty for the
purpose of necessary maintenance, repairs and possible replacement. In the case of heavily calciferous water,
we recommend the upstream integration of a customary antiliming device, as the natural formation of boiler
scale substantiates no claim for any warranty issued on the side of the manufacturer. An appropriate quality of
drinking water is required for operation of the hot water tank, as set out in the national regulations and laws
[e.g. ordinance by the Federal Minister on the quality of water intended for human consumption, TWV; Federal
Law Gazette II no. 304/2001].
MALFUNCTIONS
If the tank water is not heated up, please check whether the heat generator (oil, gas or solid fuel boiler) is fully
operative.
Please get in touch with either a licensed plumber or our customer service in the case that you are not able to rec-
tify the fault yourself. In many cases, experts only need to do a few little things and the storage tank or the system
is working again. In case of contact, please quote your model designation and manufacturing number, which you
can find on the rating plate of your storage tank.
Should a device, at the point of delivery, clearly display a malfunction, damage or other defect, this must not be
fitted, installed or used in the system. Subsequent complaints regarding devices with an obvious defect which
have been connected and installed are expressly excluded under the warranty and guarantee.
