Conditions for Installation and Operation
The necessary local building work must be ordered by the user of the machine and must be carried
out by authorised contractors in accordance with the general and local regulations. The WMF
customer service personnel are only permitted to connect the machine to the existing outlets. They
are not permitted to carry out any building work; they are also not responsible for ensuring that
this work is done.

Mains dropouts <50 ms do not interrupt machine operation
Drinking water
connection
TW 15 (DN 15, at least DN6 or ¼") with locally provided shutoff valve
and dirt filter, flow pressure at least 0,2 MPa, max. 0,6 MPa
Water quality
If the water has a hardness of more than 5° dKH (carbonate
hardness), a WMF water filter must be installed before the machine.
Water outlet line
Hose DN 19, minimum gradient 2 cm/m
Ambient
temperature
+5 °C to +35 °C (drain the water system if there is a danger of frost)
Maximum
humidity
80% relative humidity, no condensation, no splashwater.
Do not use the machine outdoors!
Installation space
For trouble-free operation and safety and to permit access for servicing,
there should be a free space of 50 mm between the rear and sides of the
machine and the walls or any non-WMF equipment. A free height of
1100 mm should be provided above the mounting surface. The height of
the mounting surface above floor level should be at least 700 mm and not
more than 900 mm. If the space below the mounting surface is to be used
for other equipment (such as a water filter or a grounds container), it
should be between 500 and 760 high, depending on the configuration and
the local connections. If the connections to the machine pass downwards
through the shelf, these will require space and the available space in the
lower compartment may be reduced.

* The on-site electrical system must comply with IEC 364. An e.l.c.b. switch with 30 mA rated fault current to
EN 61008 should be installed upstream of the unit for increased safety. An earthed socket outlet must be installed
near the unit for one-phase connection. A 5-pole CEE/CEKON socket outlet to EN 60309 must be installed for
three-phase connection. If the mains power cable of this unit is damaged, it must be replaced by our customer
service engineer or a similarly qualified person. If the machine is permanently connected on site, a disconnecting
device (master switch) to EN 60947 acting on all poles and with a contact gap of at least 3 mm must be installed
upstream. The disconnecting device is also recommended for flexible connection. The mains power cable must not
be allowed to come into contact with hot parts of the machine. Master switch and socket outlet are part of the on-
site installation. The machine must not be installed with permanent on-site connection when mounted on a trolley.
