Operation: Ice and Water Vending
During ice making soft ice is compressed thru a die
and then broken off into irregular lengths. It will not be
clear and, because of melting, when dispensed it will
not be uniform in size or shape.
Dispensing takes place when the Touch Free sensor’s
infrared beam bounces back to the sensor from a
container placed directly in front of it.
If the container is in front of the Touch Free sensor
on the left side, the ice dispensing rotor will rotate
and sweep ice over the ice dispensing chute. Ice will
continue to discharge out this chute as long as the
rotor is turning. It stops when the rotor stops.
If the user does not remove the container, ice will be
dispensed for 24 seconds and then stop.
If the container is in front of the Touch Free sensor on
the right side, the inlet water valve will open and water
will flow into the container.
If the user does not remove the container water will be
dispensed for 20 seconds and then stop.
Note: Water may dispense cloudy and then clear up in
the glass. That is normal due to air in the water and is
not an indicator of any malfunction.
Other notes:
• An occasional drip may be seen from the ice
dispense chute. This is normal and is from ice melting
inside the chute. A continuous stream of water from
the ice chute indicates a restricted bin drain.
• Clear containers (glass or plastic) may not always
activate the dispense sensors. Retry with an opaque
container.
• The drip tray is not a sink and cannot tolerate
garbage. Coffee and soda should not be discarded
into it. Debris like stirring straws that are discarded
into the drip tray will likely cause a drain back up and
need to be removed as soon as they are found.
• Both dispensing and ice making are disabled
when the unit is switched off at the controller.
Splash panel wipe-off. Wiping the splash panel could
result in unintended dispensing. To avoid that, a
disable button has been provided. It is recessed into
the bottom of the chute panel. Push and release it to
disable dispensing for 60 seconds.
Noise
This is a commercial ice machine. It contains a
powerful compressor, heavy duty gear reducer and, if
air cooled, a fan that moves a lot of air. It will produce
some noise when it is making ice. Every effort was
made during its design to minimize the sound level
but some is unavoidable.
