6.1 Operating Problems
Plugged lines and plugged filter paper account for over 90 percent of filtration system malfunctions.
A general troubleshooting chart included in this chapter provides systematic instructions to assist the
operator in diagnosing common malfunctions. Contact a factory-authorized service technician for
troubleshooting beyond the scope of the operator.
A. Plugged Lines
To guard against plugged lines when using solid shortening, let the faucet sputter for about 10-15
seconds at the end of each filter cycle. This will allow air to move through the lines and keep them
from becoming to be plugged.
B. Filter Powder and Plugged Paper
Improper use of the filter powder will cause filter paper to become plugged, sealed by a layer of
filter powder and debris. The first indication of paper plugging is a slow oil flow return rate and a
surging, jerking in the filter unit. To correct this, review the instructions for the correct use of filter
powder, and change the filter paper more frequently. When filtering several fryers prior to changing
paper, ensure that excess sediment is scraped off the filter paper after filtering each frypot. If
plugged paper remains a problem, review the chart in section 6.2 for proper diagnosis.
