CHAPTER 1: TROUBLESHOOTING/SERVICE PROCEDURES

1.1 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 and allow the heater to remain on for 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 the filter powder will cause a slow oil flow return rate. The first indication of paper
plugging 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.

1.2 General Troubleshooting

The following chart contains information to assist in diagnosing the most common malfunctions
with portable filtration systems. Possible solutions and/or corrective actions are given for each
scenario.

If the malfunction cannot be diagnosed using the information in this section, contact your Factory
Authorized Service Agent for repairs.

DANGER

Use extreme care when testing electrical circuits. Live circuits will be exposed.

DANGER

Inspection, testing and repair of gas or electrical equipment should be performed by

qualified personnel.
