Inbuilt clearances For operating, service and safety reasons the
machine should be installed with clearance of not
less than 50 mm at the back and sides from the
building or non-WMF components.
A clear height of 100 mm from the top of the sup-
porting surface should be ensured. Recommen-
ded height of the working surface is a minimum of
850 mm from floor level.
If the machine connections are to be routed down
through the counter, remember also to allow
space for the connections. These may restrict the
available space below the machine.

* The existing electricity supply must conform to the currently valid national rules (for Germany, VDE 0100).
To improve safety the coffee machine should be fitted with an FI 30 mA earth leakage current circuit breaker
to EN 61008 standards. A plug top wall socket should be fitted near the machine. If the mains connection
lead of this coffee machine is damaged it must be replaced by WMF Customer Services or a similarly qualified
person.
If the coffee machine is permanently connected to the mains then an all-pole disconnecting separator (mains
switch) to EN 60947 standards with a minimum 3 mm contact gap must be included. For flexible connection a
separator switch is recommended.
Mains cable must not come into contact with hot surfaces.
Mains switch and plug top are part of the customer‘s on-site installation.
The machine may not have a fixed permanent mains connection if installed on any mobile furniture item.
