Installation
surface /
water spray
The device must be placed and leveled on a horizontal, sturdy, water-resistant, and heatproof
base. The device must not be cleaned using a water jet. The device must be installed where it
is protected against water spray. The device must not be located on a surface that is sprayed
or cleaned with a water hose, steam jets, steam cleaner, or similar devices.
Electrical
connection
These specifications for the electrical connection and the standards quoted apply for
connecting the coffee 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 coffee machine.
The customer's on-site electrical system must be designed to meet countryspecific regulations
per IEC 60364 and must match the information on the rating plate.
An isolated ground socket or a country-specific single-phase socket for single-phase
connection, or a 5-pole CEE / CEKON socket per DIN EN 50310 VDE 0800–2-310 or a country-
specific multi-pole socket for a three-phase connection, must be available near the machine.
The sockets are part of the customer‘s on-site installation. The mains cable must not come
into contact with hot surfaces. If the mains cable for this device is damaged then it must be
replaced by our service personnel or a similarly qualified person, in order to prevent
hazards.
In order to avoid possible faults from arising in our shielded data lines due to
potential equalisation currents between the devices, an additional potential equalisation unit
should be planned for devices connected to the vending system (see DIN EN 50310 VDE 0800–
2-310). If the machine is intended to be installed in a large kitchen, it is recommended
that it be equipped with a ground potential bonding conductor. The potential equalisation
terminal is installed by WMF Service if needed.
Water supply
and drainage
The water supply must be located close to the machine (max. distance 800 mm). An anytime
easily accessible and sufficiently dimensioned water tap (preferably ball tap) as well as a dirt
filter with mesh size 0,080 mm must be installed below the counter in the water supply.
For connection from below through the counter a cut-out must be made in the hatched area
on-site according to drawing (see top view).
For drinking water with carbonate hardness above 5°dKH (carbonate hardness), a WMF water
filter should be fitted upstream.
If the coffee machine is connected to a drain connection, a funnel siphon must be installed in
the drain pipe.
Please observe that the free drain (funnel siphon with sheet metal angle) is fitted vertically.
This means that it must always be vertical to the water back pressure level that is reached. It
must be fitted in a way that the given gradient of the drain hoses (2%) is observed.
Additionally, the free drain must always be below the drains of the coffee machine and above
the actual drain pipe connections (HT40, HT50 or similar) with respect to its height.
To a funnel siphon with sheet metal angle max. two coffee machines with DN19 hose and
black silicone fabric hose should be connected. Other devices (dishwasher, sink etc.) should be
installed elsewhere.
The free drain incl. hoses must not be exposed to heavy tensile, pressure or torsional load.
Hereby, damage might be caused at the mechanical components of the free drain.
Consequently, its usability may get lost.
The on-site preliminary works for the drainage connection must be commissioned by the
operator of the machine. They must be carried out by concession plumbers in compliance
with the prevailing, national as well as local regulations.
The following drawings serve to illustrate the drains and do not include any other
connections, such as power or water infeed!
