Appendix: Technical data
Mains voltage tolerance range
230 V +6 % and -10 %,
Mains voltage interruption < 50 ms: no interruption of function
Water supply
(Constant water supply
optional)
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.
Water quality
For drinking water with carbonate hardness above 5 °dkH a WMF
water filter should be installed upstream.
Water drain pipe
Hose a min. DN 19, minimum downward slope of 2 cm/m
Ambient temperature
+5 °C to max. +35 °C (empty the water line in case of frost).
Maximum humidity
80 % relative humidity without condensation.
Do not use unit outdoors.
Degree of protection
IP X0
Installing surface
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.
Installation clearances
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.
Installation dimensions of the
water filter
See the User Manual for the water filter.
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 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.
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 shielded 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)
