PF-SERIES PORTABLE FILTRATION SYSTEMS
CHAPTER 6: TROUBLESHOOTING
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 instructions in diagnosing
common malfunctions. Contact a factory-authorized service technician for troubleshooting beyond
the scope of the operator.
A. Plugged Lines
1.
To guard against plugged lines when using solid shortening, follow these guidelines:
a.
Turn the Heater/Filter switch to HEATER 20-30 minutes before attempting a filter
cycle.
b.
At the end of the filtering cycle, let the filter bubble into the fryer through the flexible
hose for about 15-30 seconds. If it is blowing bubbles, air is moving through the lines
and the filter is less likely to be plugged.
c.
When filtering is complete, drain oil or shortening from the hose.
B. Plugged Paper
Improper use of filter powder will slow oil return. The first indication of plugged paper is a surging,
jerking movement of the hose. 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.
