De-scaling
A service inspection should be performed by authorized and qualified technical staff
every year. De-scaling of the device during this inspection is highly recommended, es-
pecially when you live in an area with hard water exceeding 12°dH (German standard
of hardness). Higher water temperature will intensify calcification. It is therefore recom-
mended to set the device at maximum 55°C (energy-saving setting) in areas with ex-
tremely hard water >16°dH.
Cleaning
The housing of the device can simply be cleaned with a damp cloth. Do not use aggres-
sive cleaners or cleaners with a scouring effect!
Legionella prevention
Do not use heated water as drinking water.
After prolonged shutdown of the device for example due to holidays, the device should
be fully heated up to the maximum temperature (tap at minimum flow) before re-using.
It is recommended to flush the pipes for one minute.

TROUBLE SHOOTING
Note: in case of problems, always consult the failure
guide!
If the water in the device is no longer heated, first check whether the plug is properly
connected to the wall socket and whether the fuse of the device group is still working.
For all other failures, please consult the failure guide.
If the device no longer works because it was connected
without being filled with water first, follow the troubleshoot-
ing guide. The device has overheated and needs to cool
down.
If the device has been reset several times, but still does
not work, please contact the party that supplied the device
originally.
