2. Disconnect the black wire from the switch and
white/black from contactor located on the outside
bottom of the component bracket .
3. With a voltmeter, check the voltage across the
black and the white/black. Connect the dispenser
to the power source. The indication must be:
a) 120 volts ac for 120 volt models.
b) 230 volts ac for 230 volt models.
If voltage is present as described, reconnect the white/
black wire to the contactor and proceed to #5.
