-
Remove each of the nuts connecting the heating elements to the vat.
-
Remove the O-ring that seals the element to the vat.
-
Lift up the rear of the heating element assembly and remove from the vat.
-
Place the heating element assembly on a flat sturdy work surface and disassemble.
Bench Build the New Heating Element Assembly
-

-
Draw a mark on the left front side of the upper heating element five inches rear of the connector flange.
-
Draw a mark on the left and right side of the upper heating element 3 1/8 inches forward of the rear of the heating element.
-
Draw a mark on the right front side of the upper heating element 4 1/2 inches rear of the connector flange.
-
Draw a mark on the right front side of the upper heating element 4 inches rear of the connector flange.
-
-
Position one high limit clip on the top front right side of both heating elements.
-
Place upper heating element on top of the lower heating element.
-
Position angled spreader and straight spreader over the high limit clips on the front right side of the heating elements.
-
Position angled spreader and straight spreader over the high limit clips on the rear right side mark on the heating element.
-
Insert four Allen screws into the right side spreader bars and to keep them together.
-
Position one angled spreader and one straight spreader on each mark on the left side of the heating element assembly. Ensure not to over tighten the Allen screws. The screws are permanently tightened when the heating element assembly is placed in the vat.
-
Insert four Allen screws into the left side spreader bars and to keep them together.
-
Place four O-rings over the wires onto the four connectors.
-
Label the wires on the upper heating element B and label the wires on the lower heating element A.
Install the Element
-
Position heating element in the vat at an angle with the front end first.
-
Route wiring through holes in the front of the vat.
-
