Removing the Drain Valve Extension
-
Disconnect the drain valve harness connector.
-
Remove the drain valve extension from valve by gripping it with hands or channel lock pliers, and then turning the tube 1/8 turn (45°) clockwise, when viewed from top down.
-
Pull the drain valve extension down and out of the drain valve.
-
Remove the drain valve extension, and then set aside.
Removing the Actuator and Drain Valve
-
Use a long 3/32 inch hex key (T-handle or socket and extensions) to loosen the set screws on the drain valve actuator until nearly all the way out, without removing.
-
Use a flat blade screwdriver and with a back and forth action, pry and remove the actuator from the drain valve.
Note the valve stem is pointed straight towards the back of fryer and the actuator label is pointing to left side of fryer.
-
Using a 2-1/2 inch socket and ratchet with extensions (large open-ended wrenches, pipe wrench) remove the drain valve by turning clockwise, when viewed from top down.
Installing the Drain Valve and Actuator
-
Install the new o-ring in to the groove at the bottom-inside of the new drain valve. Lubricate with cooking oil.
-
Apply food grade pipe thread sealant to pot drain nipple and threaded top of valve.
-
Install the new drain valve by turning counter-clockwise, when viewed from top down.
-
Turn until fully tightened and stem is pointing straight towards rear of fryer.
-
Ensure valve is in closed position.
New drain valves are shipped in the close position.
Installing the Drain Valve Extension
-
Align the two protrusions on the top of the drain valve extension with the two slots (extensions) on the drain valve.
-
Push the drain valve extension up in to the drain valve slots.
-
Using two hands or channel lock pliers, turn the tube 1/8 turn (45°) counterclockwise, when viewed from top down.
-
Ensure the bottom of the drain valve extension is square with the frame.
Installing the Drain Valve Actuator
-
With the cylindrical part of the actuator towards the right side of the fryer, and the red label pointing to the left side, align the square key of the actuator with the valve stem.
-
Push the actuator towards the valve, aligning the base of the actuator to the slot in the valve.
-
Align the actuator and valve by rotating the actuator, push actuator further towards drain valve until fully set.
Ensure the drain valve remains closed during this procedure.
-
Tighten the set screws until the actuator is tightly affixed to the drain valve.
-
Reconnect the actuator harness connector back into the fryer wiring harness.
-
Reinstall the left-side panel, and then the filter pan.
-
Return power to the fryer.
Testing the Drain Valve and Actuator
-
Access the Filter Menu.
-
Test both the drain valve and actuator by opening and closing them. Use the Fill and Drain option from the Filter Menu.
-
If the control panel displays the drain valve as open but it is closed (or viceversa), the actuator will need to be separated from the drain valve again, and the valve position rotated ¼ turn (90°) in either direction to be properly aligned.
