locate specific electrical
components. Illustrations
in the User Guide are
intended to be represen-
tative only.

Unscrew the locking screws on the wiring harness and
remove the wires.

Shut off the cooling water in feed.

Drain the Thermolator using the drain plugs

located at the rear of the unit.

Remove the four bolts that hold the heater

element in place. Use a 15/16-inch socket with 1/2-inch
drive.

Lift the heating element out of the heater tube.

Lift the element straight up.
