CHAPTER 2: IMPORTANT INFORMATION
2-2
2.1 General (cont.)
Oil or shortening is gravity-drained from the fryer into the filter pan, and then filtered through filter
paper. Filter powder, which enhances the filtering process, is distributed over the paper prior to
filtering.
All units are shipped completely assembled with accessories packed inside the filter pan. All units
are adjusted, tested and inspected at the factory before shipment.
WARNING
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent dangers of operating a hot oil filter system, particularly the aspects of
oil filtration, and draining/cleaning procedures.
A Pump switch (right switch on illustration to
the right) activates/deactivates the filter pump
(O= OFF, I= ON). The filter also has a
Heater / Filter switch (left switch on
illustration to the right) for use when filtering
solid shortening.
A thermal-overload switch on the pump motor
provides protection against overheating.
NOTE: If the thermal overload is triggered,
wait 45 minutes, and then press the
reset button to activate the circuit after
the failure has been detected and
repaired.
2.2 Rating Plate
Information on the rating plate includes model and serial numbers, as well as electrical requirements.
The rating plate is located on the back housing, near the electrical receptacle. Have the rating plate
information handy when communicating with the factory about a unit or requesting special parts or
information. Without rating plate information, proper identification of the unit cannot be confirmed.

CHAPTER 4: OPERATING/FILTERING INSTRUCTIONS
4-1
4.1 Filter Operation
WARNING
Use care when draining and filtering oil to avoid the possibility of a serious burn.
1. Sprinkle 8 ounces (1 cup) of filter powder over the filter paper, distributing the powder as evenly
as possible. If filtering a second frypot immediately after the first, add only 4 ounces of filter
powder for the second filtering.
2. Ensure the power cord is securely plugged into the receptacle on the back of the portable filter.
Plug the power cord into an 230V outlet.
3. If solid shortening is filtered through the portable filter, turn the Heater/Filter switch to (see
illustration below). The white indicator light will illuminate. Leave the heater on for 20-30
minutes before operating the filter.
Note: The filter pump cannot be activated while the switch is in the "Heater" position.
4. Ensure the pump switch is OFF (O). Turn the Heater/Filter switch to for filter operation
(see illustration below). The red indicator light will illuminate.
Use the filter heater for 20-30 minutes prior to filtering if solid shortening is filtered.
The Heater/Filter switch must be in the FILTER position before the filter pump can
be operated. The red light will illuminate when the switch is properly positioned.

CHAPTER 4: OPERATING/FILTERING INSTRUCTIONS
4-2
4.1 Filter Operation (cont.)
5. Ensure the oil is at operating temperature, 350°F (177°C). Turn the fryer off.
WARNING
The filter pan maximum capacity is 50 lbs. DO NOT OVERFILL THE FILTER PAN.
6. Place filter pan directly under fryer drain valve and
drain the oil into the filter. Ensure the oil level is no
higher than the upper oil level line (see right). Place
the filter hose nozzle inside the frypot. Turn the pump
switch to the ON (I) position to start the filter pump
(see illustration below).
Allow the oil to circulate through the frypot and filter for approximately 5 minutes
(process known as "polishing"). Polishing the oil produces maximum filtration and
extends the life of the oil. Rinse any residual oil or sediment from the frypot during the
polishing process.
Close the drain valve and return the filtered oil to the frypot. Ensure all oil is returned to
the frypot before turning filter off.
Allow the portable filter to cool, then remove and discard the filter paper. Clean the
interior of the filter pan and all components. Do not use detergent or water in the filter
pan for cleaning.

CHAPTER 5: CLEANING AND MAINTENANCE
5-1
5.1 General
Cleaning operations fall into three general categories:
•Wiping unit clean after each filter session.
•Cleaning, changing filter paper and preparing the unit for the next day’s business.
•Weekly cleaning to remove oil deposits and other particles.
WARNING
Do not use water jets to clean this equipment. To do so will damage the unit and
void the warranty.
WARNING
Never operate the filter unit unless cooking oil is at operating temperature.
5.2 Each Filter Use
Each time the 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 within a filter session. 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.

CHAPTER 5: CLEANING AND MAINTENANCE
5-2
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 service procedures. Check plumbing for leaks.
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.

PF50 CE SERIES PORTABLE FILTRATION SYSTEMS
CHAPTER 6: TROUBLESHOOTING/SERVICE PROCEDURES
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 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.
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 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.
