7.4 ADDITIONAL INSTRUCTIONS FOR FLAWLESS OPERATION
Make certain that the overflow does not produce a siphon effect.
This would produce unfavorable flows with too little solid matter entering the separator, lowering the
throughput while also interfering with the self-cleaning of the screen, which is activated by the solid mat-
ter.
NOTE
For this reason, ensure good ventilation of the overflow!
An excessively supply pump high delivery rate also causes unfavorable inflow conditions in the separator.
NOTE
The feed rate should be reduced far enough that the entire cross-section of the
overflow drainage pipe is not completely filled. As a guide value, strive for approx.
⅓ to ½ of the cross-section!
The outlet of the overflow pipe may not be submerged below the liquid level; otherwise, the inflow behav-
ior into the separator will also be negatively affected by a siphon effect.
The overflow pipe must be free of bottlenecks and dimensionally stable since clogging or a collapse would
cause the inflow pressure in the separator to become too high, forcing out the solid cake.
Make sure that the pumped medium (material to be separated)
is mixed well before separating
to avoid
“
shooting
”
or
“
clogging
”
due to irregularities.
But also ensure
that the slurry is not stirred up and
repumped too often (especially for small pre-pools) causing the slurry consistence to change (become
smooth) up to the point when no solid matter is separated at all. As a remedy, a buffer container should
be situated at the separator inflow that is filled by means of a level control.

WINTER OPERATION
If temperatures are below freezing and the separator is not operated continuously or will be stopped for
several days, take the following measures:
Ensure that all hoses and the separator are completely emptied upon switching off the device to
prevent freezing of the liquid.
Switch off the pump.
Remove the weights, the mouth piece, the auger and the screen and clean the components with a
high-pressure cleaner before storing them in a protected location.
If renewed separator operation is possible, reassemble it.
If the solid cake is not frozen completely through, it may be possible to start up the separator using the
partially frozen cake. Start the machine carefully and watch the amperemeter to prevent overloading of
the machine. It may be necessary to thaw the solid cake with hot water before the separator can be oper-
ated normally.
In order to ensure optimal operation in regions with prolonged cold periods, the separator should be in-
stalled in a shelter or room protected against freezing.
