Safety Overfl ow Switch
Location:
The safety overfl ow switch is located inside the rear of
the dispenser inside the copper overfl ow cup.
For testing or removal of the safety overfl ow 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 verifi ed at the power source, check
for continuity across the safety overfl ow switch
red wires only until the plastic fl oat is raised and
check that continuity returns when the plastic fl oat
is again lowered.
If continuity is present as described, reconnect each
of the red wires to the black wires, the safety overfl ow
switch is operating properly.
If continuity is not present as described, replace the
safety overfl ow switch.
