Insert the new sensor into the holder.

Make sure that the black bar of the sensor is

guided into the small recess on the sensor
holder.
The sensor can only be positioned the right way
round. If you insert it the wrong way round, it can-
not be pressed down.
• Screw the protective cap back onto the sensor
holder.
ATTENTION!
To activate the newly installed sensor, switch the
device on for at least one hour before the leak de-
tection. To do this, deactivate the automatic
switch-off function (press and hold the power but-
ton and M button simultaneously).
