User Manual WMF 9000 F GV
Safety and warranty
Please observe the following instructions so as to
prevent problems with and damage to the coffee
machine:
•
A WMF water filter must be fitted for drinking
water with carbonate hardness from 9 °dKH or
higher; otherwise, the coffee machine can be
damaged due to build-up of scale.
•
For insurance reasons always ensure that, at the
end of operation the mains switch is switched off
or the mains plug is unplugged. For machines with
a constant water supply, the water mains tap for the
inlet pipe must be closed.
•
We recommend damage prevention measures,
such as:
- installation of a suitable water monitor in the
mains water supply line
- installation of smoke alarms
•
After a company holiday (several days or weeks)
we recommend running the cleaning mode at least
twice before reusing the machine.
