Operation
Loading Ice
:
Allow the Vending Machine to reach operating
temperatures before loading with packaged ice.
The Vending Machine requires good air flow for
effective circulation and cooling. Avoid stacking
ice above the top edge of the air ducts that are
installed on the walls of the cabinet interior.
Blocking off these air ducts may restrict the even
distribution of cold air throughout the cabinet which
may result in warm spots developing within the
cabinet. Also, do not stack ice high enough to block
off the evaporator fans in the unit cooler assembly.
The evaporator fans are intended to pull warm air
entering the cabinet into the unit cooler and then
push that warm air across the surface of the
evaporator coil. This process removes the heat prior
to distributing the air into the cabinet.
Stocking Instructions:
1. To unlock the doors turn the Doors key to the
Unlock position - Horizontal
2. Fill the Vending Machine
3. Close the doors and turn the Doors key to the
Lock position
4. Check the doors to verify they are locking
Temperature and Defrost
Control:
The Vending Machine comes equipped with the
standard electronic control.
Operating Mode Display:

Snowflake “ON” – compressor enabled in
run cycle; control displays current cabinet
temperature.

Snowflake “Flashing” – anti short cycle
delay enabled to protect the compressor
from trying to start too frequently.

Melting Snowflake “ON” – defrost in
progress, control displays the letters “DE”

To view the control’s programmed “Set
Point” (cut-out temperature): press and
release the “Set Key.”

To initiate a manual defrost cycle: press and
hold the “Manual Defrost Key” for more
than 2 seconds.
Note:
Manual defrost will not initiate if the cabinet
temperature is above 40 degrees F.
The electronic control combines the functions of
both a mechanical thermostat and a defrost timer
into a single control. The control also offers the
consumer the capability of monitoring the
operational status of the Vending Machine via the
icon and digital temperature display (located on the
face of the control). The controls have been
programmed by the manufacturer to operate the
Vending Machine within the design parameters of
the refrigeration system. The set-point (cut-out) for
these controls has been factory programmed for 16
degrees F, with a differential of 8 degrees F. Should
the user desire to alter the Set-Point, the new set-
points should not /- 4 degrees of the
original factory setting. It is not recommended to
alter any of the parameter programming in the
controls without first consulting the manufacturer.
The control is located on top of the merchandise
and contains two thermal-couple probes. Both probe
wires are routed through the cabinet’s suction line
hole and into the unit cooler assembly, which is
mounted to the interior ceiling of the cabinet.
The air sensing probe (“P1”) routes through the unit
cooler and has its’ sensing bulb secured to the outer,
left-hand wall of the unit cooler. Probe “P1”
monitors the air temperature in the Ice Breaker at
that location. During the normal operation of the
control, the digital display will show the cabinet
temperature at the probe “P1” location.
