These specifications for the electrical connection and the standards quoted apply for
connecting the machine in EU countries. It may be necessary to also observe additional
country-specific regulations. Outside the EU countries acceptance of the standards quoted is
to be checked by the legal entity or natural person who wishes to use the machine.
The local power supply must be constructed according to IEC 364. To improve safety, the coffee machine should be
fitted with an FI 30 mA earth leakage current circuit breaker complying with EN 61008. Near the device or about 30 cm
below the counter top there should be a shockproof socket as a single-phase connection installed locally on the rear
or side wall of the counter substructure or a country-specific single-phase socket. If the mains connection lead for
this device is damaged then it must be replaced by our customer service personnel or a similarly qualified person. If
the coffee machine is permanently connected to the mains then an all-pole disconnecting separator (mains switch)
according to EN 60947 with a minimum 3 mm contact gap must be installed. A separator switch is recommended
for a flexible connection. The mains cable must not come into contact with hot surfaces. The mains switch and plug
top are part of the customer's on-site installation. The machine may not be fitted with a fixed permanent mains
connection if installed on a transporting trolley (a mobile station).
In order to avoid possible faults from arising on our screened data lines due to potential equalization currents
between the devices, an additional potential equalization unit should be planned for devices connected to the
vending system. (See EN 60309)

230 V + 6 % - 10 %,
Mains voltage interruption < 50 ms: no interruption of function
3 / 8 inch hose connector with main valve, and filter with 0.2 to
0.25 mm mesh size, on site.
Min. 0.2 MPa flow pressure at 2 l / min., max. 0.6 MPa.
Water temperature max. 35 °C.
The set of hoses provided with the new coffee machine and / or the new
water filter must be used. Do not use old hoses.
For drinking water with a carbonate hardness above 5 °dKH a WMF
scale filter should be installed upstream.

The unit must be placed on a level, flat, and sturdy surface.
The unit is not intended to be located on a surface that is sprayed or
cleaned with a water hose, steam jets, steam cleaner, or similar devices.
For operating, service and safety reasons the machine should be
installed with a clearance of not less than 50 mm at the back and sides
from the building or non-WMF components. A clear height of 1,100 mm
from the top of the supporting surface should be ensured. The height
of the installation surface above the floor is at least 850 mm. If the
machine connections are to be run downwards through the counter,
please make space for the lines, which can reduce the usable space
below the machine.
See the user manual for the scale filter.
