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. It may be necessary to also observe additional country-specific
regulations. Outside the EU 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 364 (DIN VDE 0100). An Schuko
socket or a country-specific single-phase socket for single-phase connection must be freely
accessable at all times near the machine (max. 800 mm from the machine) in case of a single-
connection. 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 it must be
replaced by our service personnel or a similarly qualified person, in order to prevent hazards.
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). In general we recommend the use of a water filter. If no
water filter is installed upstream the coffee machine may be damaged (e.g. by calcification).
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. DN 19 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. Alerternatively the machine can also be connected directly to the waste
water pipe but special care must be taken to comply with the daily cleaning of the drip tray. This is
the only way to ensure that possible contamination through direct connection is avoided.
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!
