NOTE
The liquid level monitoring device (Fig. 1,
page 6) is equipped with a shut-off valve which
opens after the unit is switched off and closes
again before starting up after the filling level has
been regulated.
If a connection between the device and the
ambient atmosphere is not possible, or
undesirable, due to the type of media used, the
line should be routed back into the equipment
behind the shut-off valve on the suction side in a
suitable way (Fig. 1. page 6).
