Maintenance
Maintenance
This device does not require any maintenance by the user. Profes-
sional maintenance should always be carried out by an expert.
If faulty, never try to repair the device yourself. Please contact
the nearest service specialist or the party that supplied the de-
vice 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.
