This filter is equipped with a three-prong, grounded plug for your protection against shock hazards and should be plugged directly into a properly grounded, three-hole
receptacle. Do not cut off, remove, or otherwise bypass the grounding prong on this plug.
If it is necessary to use an extension cord, it MUST be a three-conductor, grounded in a cord of 16 gauge or greater.
** DANGER
Do not filter more than one fry tank at a time.
Hot fluid – Do not fill above a point 1-½ inches below the OIL CONTAINER RIM.
** WARNING
This filter unit is not suitable for outdoor use. When operating this unit, it MUST be placed on a horizontal surface.

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:

• Turn the Heater/Filter switch to HEATER and allow the heater to remain on for 20-30 minutes before attempting a filter cycle.

• 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.

• 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.

1.2 General Troubleshooting (cont.)

• Tripped thermal overload switch.
•  Incorrect or no line voltage.

---|---
The pump stops during the filtering process.|

• Allow the filter unit to cool for at least 45 minutes and then press (reset) the motor thermal overload switch.
• Turn filter pump “OFF”. Allow the oil to cool then emptpan. Verify filter paper is clean and properly installed. Refill pan and restart process.

Pump starts and abruptly
stops.|
