4. MAINTENANCE
Maintenance
This device does not require any maintenance by the user. Pro-
fessional maintenance may only be carried out by duly autho-
rised technical staff.
If faulty, never try to repair the hot water device yourself.
Please contact the nearest service specialist or the party
that supplied the appliance originally.
Descaling
A service inspection should be performed by authorized and qualified technical
staff every year. De-scaling of the device during this inspection is highly recom-
mended, especially when you live in an area with hard water exceeding 12°dH
(German standard of hardness).
Care
The enclosure can simply be cleaned with a damp cloth. Do not use aggressive
cleaners or cleaners with a scouring effect!
Prolonged shutdown
Do not use heated water as drinking water.
After prolonged shutdown of the device for example due holiday, 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.
Check the filter which is incorporated in the cold water inlet of the device (blue)
regularly and keep it free from debris and dirt. This can be obtained by separating
the device from the tap. Make sure you have switched off the main power supply
and the main water supply.
