PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
A. Cooking oil/shortening is too cold
for filtering.
A. To properly filter, the oil or
shortening should be at or near
350°F (177°C). At temperatures
lower than this, the oil or
shortening becomes too thick to
pass through the filter medium
easily, resulting in much slower
oil return and eventual
overheating of the filter pump
motor. Ensure that the cooking
oil or shortening is at or near
frying temperature before
draining into filter pan.
B. Improperly installed or prepared
filter pan components.
Test: Close the drain valve.
Move the filter handle to the OFF
position, pull the filter pan (and
Power Shower, if so equipped)
from the unit. Move the filter
handle to the ON position.
If a strong stream of air is being
pumped out of the oil return port
(or the Power Shower port), the
problem is with the filter pan
components.
B. Remove the oil from the filter pan
and replace the filter paper,
ensuring that the filter paper
support screen is in place under
the paper.
If this does not correct the
problem, the filter pan suction
tube is probably blocked. Remove
the blockage using a thin, flexible
wire. If unable to remove the
blockage, call FASC.
Pump starts, but no
transfer takes place
or the transfer is
very slow.
C. Improperly installed or prepared
filter pan components (cont.).
C. Verify that filter connection
O-rings are present and in good
condition.
Replace the filter paper, ensuring
that the filter paper support screen
is properly positioned under the
paper.
