Location:

The safety overflow switch is located inside the rear of the dispenser inside the copper overflow cup.

For testing or removal of the safety overflow switch, access may also be needed by removing the two screws attaching the electronic control assembly to its mount- ing bracket.

Test Procedure:

1.Once voltage is verified at the power source, check for continuity across the safety overflow switch red wires only until the plastic float is raised and check that continuity returns when the plastic float is again lowered.

If continuity is present as described, reconnect each of the red wires to the black wires, the safety overflow switch is operating properly.

If continuity is not present as described, replace the safety overflow switch.

Removal and Replacement:

1.Disconnect the black wires from the safety overflow switch.

2.Remove the nut beneath the copper overflow cup.

3.Remove the entire switch assembly from the cup.

4.Place the new switch assembly into the cup, wires first. Make sure that a gasket is in place around the threaded switch stem.

NOTE - The magnets must be at the top of the float and there must be NO stainless steel washers installed for the safety overflow switch to operate properly.

5.Install the nut beneath the copper overflow cup. Be sure not to overtighten.

6.Reconnect the wires, FIG. 6.
