If faulty, never try to repair the device yourself.
Please contact the nearest service specialist or the party
that supplied the device originally.
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, especially
when you live in an area with hard water exceeding 12°dH (German standard of hard-
ness). Higher water temperature will intensify calcification. It is therefore recommended
to set the device at maximum 55°C (energy-saving setting) in areas with extremely hard
water >16°dH.
Cleaning
The housing of the device can simply be cleaned with a damp cloth. Do not use aggressive
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 con-
nected 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 with-
out being filled with water first, follow the troubleshooting
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 origi-
nally.
