Appendix: Technical data

Mains voltage tolerance range 230V +6 % and -10 % / 400V +6 % and -10 %.

Mains voltage interruption < 50ms: no interruption of function

Water supply 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 machine 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 and, in the case of a3-phase

connection, a5-pin CEE / CEKON-socket according to EN 60309 or acountry-speciﬁc multi-pin socket. The mains switch

and plug top 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. If the coffee machine is permanently connected to the mains then an

all-pole disconnecting separator (mains switch) according to EN 60947 with aminimum 3mm contact gap must be

installed. A separator switch is recommended for aﬂexible connection. 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)
