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, aWMFwater filter must be fitted.
Failing to use the water filter recommended by
WMFService may damage the coffee machine
(e.g. due to scale deposits).
• 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 connection, the main water supply
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
- installation of smoke detectors
• After abreak in service (lasting several days/weeks)
before another commissioning, perform “Brewing
group cleaning” at least twice.
