FIG. 14 REFILL SWITCHES

Location:

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.

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.

3. Push the new switch into the opening and spread

the clips to hold switch in the autofill box.

4. Refer to Fig. 15 when reconnecting the wires.
