2 Warnings
Complete machine safety is an integral WMF product characteristic to which we pay particular
attention.
In spite of all our safety precautions, however, every machine is potentially hazardous if not
operated properly.
This is why – for your own safety – we have summarised the warnings below and highlighted
them with a background.
Please observe the “Safety instructions” on page 45.
For your own safety,
please observe the
following instructions
Connection of the machine and starting up for the first
time must only be carried out by WMF customer service
technicians
at all times : All maintenance and repair work must only be carried
out by WMF customer service technicians or
authorised persons.
Only original parts should be used.
In no circumstances should any alteration be made to
the built-in safety devices.
Caution!
There is a danger of scalding in the vicinity of the
swivelling coffee dispenser head 14, in the vicinity of the
hot water outlet 13 and in the vicinity of the combination
spout 7. Use care when dispensing hot liquids and steam
using the swivelling coffee dispenser head 14, the hot
water outlet 13 or the combination spout 7. The liquid and
steam are extremely hot and may scald.
Caution! Risk of crushing!
Never reach into the coffee hopper 1when the machine is
switched on.
Caution! Health hazard!
When handling the cleaner, always follow the safety
instructions on the pack. The cleaner is caustic and can
hurt. Because cleaning fluid flows out of the swivelling
coffee dispenser head 14 or the combination spout 7
during cleaning, place a collection tank (capacity at least
1.4 litres) below the machine to collect the cleaning fluid
safely (for machines without drain connections only).

3 Safety instructions
General notes
1. At the end of the working day always ensure that the shut-off device on the water pipe
supplying the machine is closed and the main power switch to which the machine is
connected is switched off and/or the plug is removed from the socket.
2. The component-tested safety devices fitted prevent inadmissible pressure and temperature rise
in the boiler. If the safety valve is activated, the machine should be switched off immediately
at the customer’s main switch. Switch off the machine if a boiler malfunction occurs. Contact
the WMF customer service department and do not switch the machine on again until the fault
has been remedied.
3. This machine is not for use out of doors. In case of freezing the machine should be drained
beforehand to prevent frost damage.
4. Never spray the machine with a hose. Steam cleaners, steam-jet cleaners and similar
equipment must not be used to clean the machine. Clean the surface by wiping with a damp
cloth, or use products from our WMF care range.
5. The unit must stand safe at a ground level, on a horizontal and stable base.
Machine shutdown – holidays
1. If the machine is to be shut down for an extended period, a general clean should be carried out
beforehand and the grouts container must be emptied. If there is any risk of freezing, the
machine should be drained beforehand to prevent frost damage. In such cases, call in the
WMF customer service personnel in good time.
2. After several weeks of shutdown for holidays, we recommend that the fully automatic cleaning
program be run at least twice before the machine is started up again.
Hot water boiler data – see rating plate
The hot water boiler complies with the Pressure Equipment Directive 97/23/EC - Category 1,
Module A.
The hot water boiler is subject to neither notification nor licensing. Each hot water boiler is
subjected to hydrostatic tests before delivery to the customer.
The operator of such equipment is responsible for due maintenance and verification of the safety
mechanism.
The machine complies with all the relevant regulations.
The operator is obliged to ensure that electrical plant and equipment is tested to establish that it is
in safe working order (e.g. german law BGV A3).

46
This device is subject of the directive on waste electrical and electronic equipment
(WEEE/EU directive) and may not be disposed of as domestic waste.
Preventive measures to avoid 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 takes 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 5° (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.
