1.9 Built-in Filtration System Service Procedures

1.9.1 Filtration System Problem Resolution

One of the most common causes of filtration problems is placing the filter paper on the bottom of the
filter pan rather than over the filter screen.

CAUTION
Ensure that filter screen is in place prior to filter paper placement and filter pump
operation. Improper screen placement is the primary cause of filtration system
malfunction.

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of
the filter paper, and ensure that the correct size is being used. While you are checking the filter paper,
verify that the O-rings on the pick-up tube of the filter pan are in good condition. A missing or worn
O-ring allows the pump to take in air and decrease its efficiency.

If the pump motor overheats, the thermal overload will trip and the motor will not start until it is reset.
If the pump motor does not start, press the red reset switch (button) located on the rear of the motor.

If the pump starts after resetting the thermal overload switch, then something is causing the motor to
overheat. A major cause of overheating is when several frypots are filtered sequentially, overheating
the pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation.
Pump overheating can be caused by:

1-9

 Solidified shortening in the pan or filter

Sediment Particle

lines, or

 Attempting to filter unheated oil or

shortening (cold oil and shortening are

Oil Flow

more viscous, overloading the pump
motor and causing it to overheat).

If the motor runs but the pump does not return
oil, there is a blockage in the pump. Incorrectly
sized or installed paper will allow food particles
and sediment to pass through the filter pan and

Sediment Particle

Up for reverse

into the pump. When sediment enters the pump,
the gears bind, causing the motor to overload,
again tripping the thermal overload. Shortening
that has solidified in the pump will also cause it
to seize, with the same result.

Down for forward

A pump seized by debris or hard shortening can
usually be freed by manually moving the gears
with a screwdriver or other instrument.

Disconnect power to the filter system, remove the input plumbing from the pump, and use a
screwdriver to manually turn the gears.

● Turning the pump gears in reverse will release a hard particle.

● Turning the pump gears forward will push softer objects and solid shortening through the pump

and allow free movement of the gears.

Incorrectly sized or installed paper/pads will also allow food particles and sediment to pass through
and clog the suction tube on the bottom of the filter pan. Particles large enough to block the suction
tube may indicate that the crumb tray is not being used. Pan blockage can also occur if shortening is
left in the pan and allowed to solidify. Blockage removal can be accomplished by forcing the item out
with an auger or drain snake. Compressed air or other pressurized gases should not be used to force
out the blockage.

1.9.2 Replacing the Filter Motor, Filter Pump, and Related Components

1. Remove the filter pan and lid from the unit. Drain the frypots into a Shortening Disposal Unit

(SDU) or other appropriate metal container.

DANGER

DO NOT drain more than one full frypot into the SDU at one time.

2. Disconnect the fryer from the electrical power supply and reposition it to gain access to both the

front and rear.

3. Disconnect the flexline running to the oil-return manifold at the rear of the fryer as well as the

pump suction flexline at the end of the filter pan connection (see photo below). On some models a
third flexline may need to be disconnected.

Disconnect flexlines indicated by the arrows.

4. Loosen the nut and bolt that secures the bridge to the oil-return manifold.

5. Remove the cover plate from the front of the motor and disconnect the motor wires.

6. Unplug the pump motor assembly 6-pin connector C-2.

7. Remove the two nuts and bolts which secure the front of the bridge to the cross brace and carefully

slide the bridge rearward off the cross brace until its front end can be lowered to the floor. Undo
the single nut holding it in place in back. Be careful not to let the rear of the bridge slip off the
manifold at this point.

8. Get a good grip on the bridge, carefully pull it forward off the oil-return manifold, and lower the

entire assembly to the floor. Once on the floor, pull the assembly out the front of the fryer.

9. When required service has been completed, reverse steps 3-8 to reinstall the bridge. NOTE: The

black motor wires go on the top terminal, the white on the bottom. The red/black heater tape wires
go into position 3 and the violet/white wires go into position 6 (see illustration below).

10. Reconnect the unit to the electrical power supply, and verify that the pump is functioning correctly

(i.e., when a filter handle is placed in the ON position, the motor should start and there should be
strong suction at the intake fitting and outflow at the rear flush port.)

11. When proper operation has been verified, reinstall the back panels and the filter pan and lid.

12. Reposition the fryer under the exhaust hood and reconnect it to the electrical power supply, if

necessary to return the fryer to service.

1.9.3 Replacing the Transformer or Filter Relay

Disconnect the fryer from the electrical power supply. Remove the left controller from the fryer to
expose the interior of the left component box. The transformer and relay on the left are located as

shown in the illustration below. NOTE: The right component box is identical to the left except that

the transformer and relay on the left side are not present. Once replaced, reconnect the power.

When replacing a filter relay in the left component box, ensure the 24VAC relay (8070670) is used on
208-240V units and 8070012 is used on 120V units. This relay is the same relay used in the RE
fryers.

1.10 Control Power Reset Switch

The control power reset switch is a
momentary rocker switch located behind
the control box, (see Figures 6 and 7)
beneath the far right controller, which
resets all power to all the controllers and
boards in the fryer. It is necessary to reset
all power after replacing any controller or
board. Press and hold the switch for at
least ten seconds when resetting the control
power to ensure power has sufficiently
drained from boards.

turned on.

D. Ensure fuse holder is screwed in

properly.

E. Swap the controller with a

controller known to be good. If
controller functions, replace the
controller.

F. Swap with a harness known to be

good. If controller functions,
replace the harness.

G. If any component in the power

supply system (including the
transformer and interface board)
fail, power will not be supplied to
the controller and it will not
function.

A. Wait until the previous filtration

cycle ends to start another filtration
cycle. This may take up to one
minute. If filter busy is still
displayed with no activity, remove

and restore ALL power to the fryer.
