WMF 5000S User Manual page 81

Please observe the following instructions so as to
prevent problems with and damage to the coffee
machine:
• For water with a carbonate hardness in excess of
5°dKH, a WMF water filter must be fitted; 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 main water supply tap is turned
off and the mains switch is switched off or the
mains plug is unplugged.
• We recommend damage prevention measures, such
as:
- installation of a suitable water monitor in the
mains water supply
- installation of smoke alarms
• After shut off for several days we recommend
running the cleaning program at least twice before
reusing the machine.
