This switch removes power to the element when the element is
raised. If a constant "E-31" "HEATING ELEMENTS ARE UP",
is shown on display when elements are lowered into vat, check
element safety switch.
To avoid electrical shock or property damage, move
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.

screw at control panel top, slide panel down slightly to
