The refill switches are located on the upper right
front of the autofill box.
Test Procedures:
1. Disconnect the dispenser from the power source.
2. Disconnect the two white/red, brown/black or
red/black wires from the switch terminals.
3. Connect the dispenser to the power source. Check
for voltage across the white/red, brown/black or
red black wires from the test/operate switch and
the white wire on solenoid #2 or #3. The indication
must be:
a) 120 volts ac for two wire 120 volt models
b) 200 to 240 volts ac for two wire 200 or 240 volt
models.
c) 230 volts ac for two wire 230 volt models.
4. Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to the Wiring
Diagrams and check dispenser wiring harness.
5. Check for continuity across the switch terminals
with the switch in the “ON” position. Continuity
must not be present when the switch is in the “OFF”
position.
