Ventilation If ventilation possibility is limited sufficient ventilation need to be provided e.g machine on feet
extension, active ventilation, additional ventilation slots/ openings in counter area. Ventilation
slots must not be covered. Under certain circumstances a forced ventilation on site is necessary
to ensure heat dissipation.
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 local power supply must be constructed according to the currently valid IEC 364 (DIN VDE
0100). An isolated ground socket or a country-specific single-phase socket for single-phase
connection, or a 5-pole CEE / CEKON socket per EN 60309 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 on 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 EN 60309)
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!
