Operating Manual for
FAN Press Screw Separator PSS 1.1-300
S
The plastic profile rails serve to dampen the impact shocks of the separator on the screen guide rails
and reduce friction.
The screen

] in the guide rails, depending on how hard the solid cake is. The slight up
and down movement of the output regulator lever arms are an indication of the
“
floating
”
of the screen in
the separator housing.
Inspect both the screen and the plastic profile rails inserted into the guide rails for any wear. If uneven
wear is discernible on the plastic profile rails, these must be replaced with new ones. When inserting a
new screen, the plastic profile rails must naturally also be replaced.
Solid matter in the area of the guide rails must be washed out.
ATTENTION!
Never loosen the fastening bolts of the screen guide rails on the housing as these
are precision components that must be handled with care.
The screen guide rails are aligned during assembly of the sepa-
rator using a special template then fixed in place with the fas-
tening bolts and should not be loosened again. However, if the
setting is changed due to an error, they must be realigned. You
can obtain the required alignment template along with instruc-
tions from your nearest FAN dealer.
Follow the instruction in sections 6 and 7 to restart the machine.
Also clean the area in which the wear ring sits. This is located at
the rear of the housing at the transition to the inflow area and is
affixed to the housing with 4 bolts. This ring protects the housing
from wear as the screen
“

during operation. The wear
ring should be replaced no later than after radial wear of approx.
1 mm (when the inner diameter of the wear ring is approx. 153
mm) in order to prevent screen damage.
For
this, remove the 4 bolts located inside on the wear ring. Pull
the wear ring out of the screen housing and replace it with a new
one.
