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 continuity is present as described, reconnect the wires to the switch terminals.

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