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.
For operating, service and safety reasons the machine
should be installed with a clearance of not less than
2 inch (50 mm) at the back and sides from the building
or non-WMF components. A clear height of 44 inch
(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 34 inch (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.
See the user manual for the scale filter.
