2.) Interrupt the suction sequence by briefly switching off the
suction turbine if the level is the same. By doing this, the
pumping sequence is not interrupted. Switch the suction tur-
bine on again as soon as the level of liquid in the container has
correspondingly sunk.
4.4 Aspiration of strongly contaminated liquids
The Permanent Aspirator is equipped with a collection filter cage
in order to protect the feed pump. To empty the filter cage, turn
it counter clockwise and take it out of the holder. Empty the filter
cage and re-insert. Remember that with strongly contaminated li-
quids it should be regularly emptied because if it is full it will grea-
tly reduce the suction power.
4.5 Care and maintenance
Any special maintenance measures are not required owing to the
sturdy construction of the Vetter aspirator. The suction hoses are
not, under any circumstances, to be cleaned with a hot water high
pressure cleaner, as for example can be done with the containers.
The motor head with the suction turbine is maintenance-free and
does not therefore require any special maintenance.
