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. 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.
Connect the dispenser to the power source. 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.
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 wir-
ing diagrams and check the 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.
If continuity is present as described, reconnect the
wires to the switch terminals.
If continuity is not present as described, replace the
switch.
Removal and Replacement:
1. Remove the wires from the switch terminals.
2. Compress the clips inside the autofill box and
gently push the switch through the opening in the
front of autofill box.
