Preventive measures against consequential machine damage
Any technical devices, particularly large fully automatic machines, are a potential source of
danger when operated without supervision.
We therefore recommend that the operator take appropriate action to prevent damage, for
instance installing a suitable water detector in the site water supply line.
If the local water has a carbonate hardness of more than 9° (German hardness), a WMF water
filter must be installed in the supply line to the machine.
Maintenance intervals depend on how heavily the machine is used and on local water
conditions, and should be fixed by agreement with your service engineer. Even in the case of
light use, maintenance should be carried out at least once a year and the water filter, if fitted,
should be replaced.
