User Manual WMFpresto!
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 mains tap, and filter with 0.2to
0.25mm mesh size, on site.
Min. 0.2MPa flow pressure at 2litres/minute, 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 fitted upstream.
Water drain tube Tube aminimum of DN 19, minimum downward slope of 2cm/m
Ambient temperature +5°C to max. +35°C (empty the water system in case of frost).
Maximum humidity 80 % relative humidity without condensation.
Do not use device outdoors.
Degree of protection IP X0
Installation surface The device must be placed on alevel, flat, and sturdy surface.
The device 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minimum working space of 800mm in front of the coffee
machine is recommended. 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
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.
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 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 IEC 364 (DIN VDE 0100). To improve safety, the device should
be fitted with an FI 30mA earth leakage current circuit breaker complying with EN 61008. (Type Bresidual current
circuit breakers provide reliable tripping even if the fault current is smooth. This ensures ahigh level of safety.) 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. The mains cable must not come into contact with hot surfaces. The mains switch and plug
top are part of the on-site installation. The coffee 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 equalisation currents
between the devices, an additional potential equalisation unit should be planned for devices connected to the
vending system. (See EN 60309)
