Mounting instructions

Installation position
When mounting the device, keep a distance of at least 200 mm (7.874 in) from the
vessel wall. If the device is installed in the center of dished or round vessel tops,
multiple echoes can arise. However, these can be suppressed by an appropriate
adjustment (see chapter " Setup").
If you cannot maintain this distance, you should carry out a auto false echo
suppression during setup. This applies particularly if buildup on the vessel wall is
expected. In such cases, we recommend repeating the auto false echo suppression at
a later date with existing buildup.
