Conditions for usage and installation
Any necessary on-site preparatory work for electricity, water and drainage connections at the customer‘s premises
is to be arranged by the machine owner / operator. The work must be carried out
by authorised installation technicians in compliance with general, country-specific and local regulations.

exceeds 0.6MPa (6 bar) a pressure reducer must be connected upstream
which must be set to a maximum of 0.6 Mpa. For fixed water operation
the connection items included in the accessories must be used. Do not
use old hose sets.

Installation
Clearance
For operating, service, and safety reasons the machine should be installed with a clearance from
the building or non-WMF components of not less than 50 mm at the sides and 60 mm at the
back. A minimum working space of 800 mm in front of the coffee machine is recommended.
Clearance of at least 200 mm above the product hopper is recommended. The height of the
installation surface above the floor is at least 850 mm. If the coffee 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.
If the coffee machine is operated with a water filter the additional space under the machine
depending on the filter size has to be considered. For further information see filter instructions.
Caution: Auxiliary units can only be installed on the right side of the machine (seen from the
operating side)
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.

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. 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-
phase
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!
