Burn Risk Do not attempt this procedure while the fryer is in use or the vat is hot. Severe burns may result. Only perform this procedure when the fryer is cool and disconnected from the power source. |
Filter motors can be replaced independent of the filter pump or together as an assembly. When replacing just the filter motor, seal kit 17476 must be ordered. When reusing an old filter pump it is recommended to replace the filter pump rollers. Order filter pump roller kit 17446.
Filter Motor (Pump) Removal
This procedure has two main steps, remove the drain valve assembly from the vat's drain and then disassemble the drain valve.
-
Ensure the oil is drained from the vat and filter pan.
-
Remove the filter pan.
-
Remove power from the fryer.
-
Remove the left and right side panels to access the filter pump motor.
-
Use an adjustable wrench to disconnect plumbing from the inlet and outlet sides of the filter pump.
-
Use a cross-tip head screwdriver to remove the access cover on the rear of the old motor.
-
Note the location of the L1 and L2 power wires and disconnect.
-
Remove the jam nut holding the wire conduit to the side of the filter motor and remove the conduit and wires.
-
Remove the four nuts and washers that hold the filter pump and motor to the frame and then remove.
Check New Filter Motor Wiring
There is a wiring diagram on the pump motor's data plate. One side displays a low voltage wiring application and the other is for high voltage applications. Most pumps are pre-wired for high voltage applications; however to ensure the pump is wired correctly, do the following;
-
Use a cross-tip head screwdriver to remove the wiring access cover on the rear of the new pump motor.
-
Note the location of the wire connections, and then compare them to the wiring diagram on the pump motor's data plate.
-
Ensure the wires are connected according to the application requirement. If not, use the wiring diagram on the motor's data plate to change the wiring as applicable.
-
Leave the wiring cover plate off so power wires can be attached later in the installation.
Migrate an Old Filter Pump to a New Filter Motor
The filter pump attaches to the end of the filter motor.
-
If an old filter pump is being reused on a new filter motor, order and install seal kit 17476 on the new filter motor. Replace the old rollers and O-ring in the old filter pump with 17446.
-
If the entire filter pump and motor assembly is being replaced continue to Filter Pump / Motor Installation.
Remove the Filter Pump
With the old filter pump on a flat sturdy work surface do the following:
-
Remove the two screws connecting the filter pump to the face of the filter motor.
-
Separate the pump and motor assemblies.
Install the Filter Motor Seal Kit
The oil seals prevent oil from migrating into the motor assembly. With the new filter motor on a flat sturdy work surface use seal kit 17476. Install the pump seal components on the new filter pump motor.
Install New Rollers
The rollers inside the filter pump that create the oil pressure, wear and require replacement. Use kit 17446 to replace the rollers.
-
Remove the four screws attaching the cover to the filter pump, and then remove the cover.
-
Replace the five old rollers with the new rollers.
-
Replace the cover's old O-ring with the new O-ring.
-
Install the cover using four screws on to the filter pump.
Install the Filter Pump
Installing the filter pump to the filter motor is difficult because the internal pump propeller is offset slightly. To easily assemble the filter pump to the motor, do the following:
-
Place the new filter motor on a flat, sturdy flat surface.
-
Obtain the filter pump, and orient it so the double notches on the housing are facing down.
-
With one sharp motion or snap, give the filter pump a downward shake. The rollers and propeller snap in to alignment.
-
Without changing the orientation of the filter pump, slide it on to the filter motor's shaft. Ensure that the filter pump is fully engaged.
-
Install the four screws holding the filter pump to the filter motor.
Filter Pump / Motor Installation
-
To install the filter pump / motor, use the four nuts and washers that hold the pump to the frame, and leave loose.
-
Install the wire conduit and jam nut, which holds the wire conduit to the side of the filter motor.
-
Connect the L1 and L2 power wires from the conduit to the filter motor connections.
-
Use a cross-tip head screwdriver to install the access cover on the rear of the filter motor.
-
Use an adjustable wrench and Loctite where applicable. Connect the inlet and outlet plumbing.
-
Tighten the four nuts and washers holding the filter pump / motor to the frame.
-
Replace the filter pan.
-
Reconnect the power.
-
Add oil to the vat and run a filter cycle while checking for leaks.
-
If leaks are discovered, repair as necessary.
-
Install the left and right side panels.
