This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
DANGER – Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow
stripes is the equipment grounding conductor. If repair or replacement of the cord or plug is necessary , do not connect the equipment-grounding conductor to a live terminal. Check with a qualified
electrician or serviceman if the grounding instructions are not completely understood, or if in doubt
as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
WARNING – When using electric appliances, basic precautions should always be followed, including the following:
a)Read all the instructions before using the appliance.
b)T o reduce he risk of injury , close supervision is necessary when an appliance is used near
children.

to 30 minutes before placing the ice in the dispenser.
ICE STORAGE AND DISPENSING
o
F.
Ice is stored in the dispenser’s bin. Ice is transported from the bottom of the bin to the ice dispense point by the paddle
wheel. The injection molded paddle wheel has paddles which lift the ice to the dispense point.
PUSH LEVER ICE DISPENSING
The customer’s cup presses against the push plate. The
push plate then raises a microswitch actuator arm on the
right side of the dispensing chute. The microswitch actuator arm hits the lever of the microswitch.
The energized microswitch activates the solenoid, which
pulls down the solenoid plunger. The plunger is connected
to a cable, which is then connected to a pulley . This raises
the door of the ice chute.
The energized microswitch also activates the gear motor.
The gear motor turns the agitator and paddle wheel, lifting
the ice from the bottom of the bin to the ice dispenser point.
Ice falls forward through the open door, through the bin
spout, through the ice chute and into the customer’s cup.
