4.7 Disengaging the pre-separator using the bypass
valve
The pre-separator (pos 8 Figure 3-1, page 8 ) is equipped with a bypass valve (pos 7
Figure 3-1, page 8 ). This valve makes it possible to use the dust extractor even
during replacement of the Longopac on the pre-separator.
To close the bypass valve, pull the valve closed according to Figure 4-9, page 22 . A
closed bypass valve blocks the connection between the pre-separator's cyclone and the
volume that stores the dust before it ends up in the Longopac. It will not then be
possible to separate the dust with the pre-separator; instead it continues directly into the
dust extractor.
When the valve is closed, there is normal pressure in the volume for the pre-separator's
dust collection and the dust that has collected falls down into the Longopac. Should the
Longopac be full of dust, it can now be replaced. If it is not full, the valve can be slid
back according to Figure 4-10, page
22 .
To continuing work, the bypass valve must be in its original position.
