Safety and warranty
Please observe the following instructions so as to
prevent problems with and damage to the coffee
machine:
• For drinking water with carbonate hardness from
5°dKH or higher, aWMFwater 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 mains switch is switched off
or the mains plug is unplugged. For machines with
aconstant water supply, the water mains tap for the
inlet pipe must be closed.
• We recommend damage prevention measures,
suchas:
- installation of asuitable water monitor in the
mains water supply line
- installation of smoke alarms
• After shut off for several days we recommend
running the cleaning program at least twice before
reusing the machine.
