5.2 Each Filter Use
Each time the PF-series portable filter is used:
•Wash down the insides of the filter pan with hot oil during the filtering process. DO NOT
allow excessive residue buildup to occur inside the filter pan.
•Change filter paper after each filter session or at the end of the day. Scrape excess sediment
from filter paper after each frypot is filtered. If oil is not returned to the frypot within 7
minutes, the filter paper may be clogged. Change filter paper if this occurs.
•Wipe up any oil which may have splashed or spilled.
•Wipe all exterior surfaces of the filter unit.
WARNING
Do not run water or boil-out solution through the portable filter. Doing so will cause
irreparable damage to the pump, and void the warranty.

5.3 Daily— Close Of Business
At the close of a working day, filter the oil in all fryers. When the last fryer is filtered, follow these
steps:
1. Ensure the flexible hose and pump lines are clear by running the filter pump for an
additional 15–30 seconds after air bubbles start coming from the oil return line. Drain the
flexible hose as much as possible, especially if solid shortening is used.
2. Remove the filter pan cover and hold-down ring, and then remove the filter paper and filter
paper support screen.
3. Discard filter paper.
4. Wash all filter components with hot soapy water and rinse. DO NOT use soap and/or water
inside the filter pan. Wipe residual oil and sediment from inside the filter pan with a clean
cloth or paper towel.
5. Rinse all parts with clean water (except filter pan interior), and then dry all filter parts
thoroughly before reassembling.
6. Check the hose fitting on the pump and ensure that it is tight. Check plumbing for leaks.
See Chapter 6 for troubleshooting procedures. Check plumbing for leaks.
DANGER
The crumb tray (if applicable) in portable filter systems must be emptied into a
fireproof container at the end of frying operations each day. Some food particles
can spontaneously combust if left soaking in certain shortening material.
5.4 Weekly
Follow the same procedure as for "Daily", with these additional steps:
•Clean built-up residue and debris from filter pan by wiping with a clean cloth or paper
towel. DO NOT use soap and/or water inside the filter pan. Ensure all components fit
properly and function correctly.
•Clean thoroughly under, around, and behind the fryers and filtering area with hot soapy
water and rinse.
•Check the hose connection and tighten if hose becomes loose and starts to leak oil.

PF-SERIES PORTABLE FILTRATION SYSTEMS
CHAPTER 6: TROUBLESHOOTING
6-1
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.
6.2 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 Servicer 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.
