Storage and Unpacking
Storage:
The Vending Machine should be stored and
transported in an upright position. If the Vending
Machine is tilted beyond 45 degrees of vertical, oil
may drain from the compressor casing. Should this
occur, it’s recommended that the Vending Machine
be returned to a vertical position for at least 1 hour
before energizing the unit. This will allow oil that
may have migrated out of the casing an opportunity
to drain back to the compressor.
Unpacking:
Prior to installation, the outer packaging on the
Vending Machine will need to be removed. The
majority of the packaging materials can be recycled
and disposed of in an environmentally friendly
manner. The wooden skid is secured to the
Vending Machine with hex-headed screws and will
require the use of a 3/8" hex-socket for screw
removal.
Vending Machine Pallet Removal:
1. First remove two screws from each side
perimeter board using a long 3/8” hex-
socket.
2. Remove the six Philips screws from the
front perimeter board and remove board.
3. Remove two Philips screws from the left or
right side. This will remove the skid footing
to aid in use of pallet jack.
4. Insert pallet jack from the front side.
CAUTION: Stay clear of the load cells.
5. Use lifting device to lift the unit high
enough to remove pallet and the orange
pallet cushions from the back.
6. Slide unit off of the pallet jack into position
on a sturdy level surface. Use stackers
included if needed.

End of Vending Setup Instructions
Installation Location:
The Vending Machine should be located on a solid
level base and must be level to operate properly. If
the Vending Machine is exhibiting a slight forward
lean, the front of the cabinet should be blocked to
bring the cabinet to a level position. A unit that is
not level could result in ice buildup due to improper
water drainage during the defrost cycle.
In vending units, improper leveling may cause
inaccurate weight measurements. Contact on any
part of the Vending Machine other than the skid
plates and/or leveling kits will result in inaccurate
weight measurement.
Leveling Kits No. 1050019, are included
and must be installed by customer to qualify
for NSF approval.
The installation location must also provide good air
flow for the designed refrigeration system to
operate efficiently. WARNING: DO NOT block
the refrigeration grill openings. Grill blockage may
result in compressor failure.
When placing the Vending Machine, there should
be a minimum of 3 inches of air space between all
sides of the cabinet and any surrounding structures.
This air space allows for air flow over the surface of
the cabinet, thus reducing condensation and aid in
the drying of these surfaces. The 3 inch space
behind the Vending Machine will also help ensure
that the evaporator drain tube, which exits the back
wall, is not being restricted or blocked during the
defrost cycle.
Locate the Vending Machine so that the main power
cord is within reach of an electrical outlet.
WARNING: DO NOT use extension cords as they
decrease the voltage to the unit and ultimately cause
compressor failure.
Outdoor Vending locations shaded from sunlight
are recommended for more economical operation.
Electrical Supply:
NOTE: Electrical and refrigeration repair work
should be done by licensed professionals.
The Vending Machine must be plugged into a 115
volt, 60 Hz grounded electrical outlet with a circuit
fuse or breaker rated at a minimum of 15 Amps.
The electrical service connections to the Vending
Machine must be a dedicated line and compliant
with national electric code and local codes that may
apply. DO NOT use extension cords. Some models
are equipped with a main power switch. If so
equipped, make sure the switch is in the OFF
position before plugging the merchandiser into the
outlet. Plug the merchandiser power cord into the
lower receptacle of the electrical outlet. Turn the
switch if equipped into the ON position. After a few
seconds delay, the compressor and the condenser
fans should start. The evaporator fan motors and the
light fixture should start immediately when power is
applied. The condensing unit will continue to run
until the air temperature in the cabinet reaches +16
degrees F.
WARNING: Operating more than one appliance on
the same circuit may result in voltage fluctuations
when both appliances are operating simultaneously.
This voltage fluctuation may lead to premature
compressor failure.
Information regarding the electrical voltage and
frequency being supplied to the Vending Machine
can be found on the Vending Machine’s serial data
plate typically located at the upper left hand corner

[6]
of the Vending Machine’s interior. Information
regarding the maximum fuse/circuit breaker size
required for the specific Vending Machine model is
available from the condensing unit data plate.
Condensate Evaporator Pan
If the Vending Machine has a condensate
evaporator, remove from inside merchandiser and
install evaporator on back of unit per instruction
sheet inside carton then plug the cord into the upper
receptacle of the electrical outlet and the heater rod
will begin to heat. The unit must be placed so that
there is at least 1 inch of air space between the back
surface of the condensate evaporator housing and
any wall surface behind the cabinet. Failure to
install this assembly on an indoor unit would result
in water being generated during the defrost cycle
which will drain directly onto the floor of the unit.
This may result in water damage to the floor and
create a hazardous slip condition in the area
surrounding the merchandiser.
Start-up the Vending Machine at Retail
Location:
1. Prior to energizing the Vending Machine, place

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 exceed +/- 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.

Probe “P2” is inserted into the finned section of the
evaporator coil, near the top of the unit cooler
assembly. This probe monitors the temperature of
the evaporator coil during the defrost cycle. The
control is factory programmed to engage the defrost
cycle in 4 hour intervals. The defrost cycle is set to
run for 16 minutes, unless the temperature at “P2”
reaches 50 degrees F prior to the end of the cycle.
Should that occur, the temperature at “P2” will
override and end the defrost cycle. During the
defrost cycle, the control will display the letters
“DE” along with the melting snowflake icon.
Possible Displayed Alarm Codes:
“P1” –Air probe failure: The control will override the
“P1” functions and cycle the compressor at 5 minute
intervals, until the probe fault can be corrected.
“P2” –Evaporator probe failure: The control will
override the “P2” function and operate with a timed
defrost cycle, until the probe fault can be corrected.
“HA” –Maximum temperature alarm: The cabinet air
temperature has exceeded programmed maximums for a
period exceeding 15 minutes. The alarm will continue to
display until the cabinet temperature drops below
maximum levels.
“LA” –Minimum temperature alarm: The cabinet air
temperature has dropped below the programmed
minimum. This alarm will continue to display until the
cabinet temperature rises above the minimum level.
Note: Should a “P1” or “P2” alarm occur, check the
probe wire connections to the control prior to replacing
the probe wire.

merchandisers/merchandiser-sales-distributors/
The defrost circuit is equipped with a defrost
termination switch. This switch is attached to one of
the evaporator coil tubes (located inside the unit
cooler assembly). This switch senses temperature
and will cycle power off to the defrost heat element
should the temperature at the surface of the switch
reach 70 degrees F. This switch only terminates
power to the heat element and will not end the
timed defrost cycle. Once the Vending Machine has
returned to run mode, the termination switch will
re-set when the temperature at its’ surface reaches
35 degrees F.
Maintenance
General:
The recommended preventive maintenance intervals
will often vary depending upon the environment in
which the Vending Machine operates. A preventive
maintenance plan should be developed to aid in
determining realistic cleaning intervals.
Cleaning Condenser Coils:
It is recommended to inspect and clean the
condenser coil and fan blades every 3 month.
There are a variety of methods available for
cleaning the condenser coils. Keep in mind that the
debris is being drawn into the coil by the condenser
fan and the debris should be removed in the
opposite direction.
The simplest and preferred method would
involve the use of a vacuum cleaner to suck the
debris out of the coil from the outside surface.
Another method is using compressed air to blow
dust from the coil. The debris should be blown
out from the inside surface of the coil.
Note: Maintenance and repair of the electrical and
refrigeration systems should only be performed by
trained and qualified personnel.
The defrost termination switch functions as a
possible fire protection device. Do not remove or
by-pass the termination switch from the defrost
circuit.
WARNING!

[9]
WARNING: When using the compressed air, there
may be a cloud of dust released into the air
surrounding the machine.
It is recommended that the service person wear the
proper protective equipment (i.e. safety glasses and
a dust mask) when performing coil cleanings.
Note: DO NOT use any type of filter media in front
of the condenser coil to trap dust. Filter testing has
proven to create enough restriction of air flow to
reduce the efficiency of the coil’s heat exchange.
Defrosting:
The Vending Machine is designed to be self-
defrosting. They are equipped with an electronic
control that is factory set to run a maximum of 16
minute defrost cycle every 4 hours.
The heat generated by the defrost heater element
will melt the ice build-up on the evaporator coil and
the resulting water will drain through a tube out of
the back wall of the machine.
It is recommended to check the operation and
condition of the evaporator coil and for signs of
excessive ice buildup every 3 months.
Cleaning the Vending Machine:
The exterior of the Vending Machine including the
doors, can typically be cleaned with the use of
detergents dilluted in warm water followed with a
tap water rinse.
The exterior paint is capable of withstanding the use
of polishing compounds and most solvents. If using
stronger cleaning agents, they should be tested on a
small, inconspicuous areas prior to application onto
visible surfaces of the Vending Machine.
When cleaning the interior of the Vending Machine,
the use of detergents with strong odors (i.e. citrus
based cleaners), abrasive cleaners containing
chlorine bleach, and any form of solvent based
cleaners are not reccommended. They may leave
objectionable odors inside the cabinet which may be
absorbed by the ice being stored in the Vending
Machine.
Vending Machine Door Maintenance:
Routine inspection of the door gasket seal and the
action of the door’s hinges are recommended.
Door gaskets may mildew and stiffen over time.
The gasket is made of a soft, flexible PVC and can
be cleaned using most kitchen and bath cleaners
designed for mildew removal. Review manufacturer
information and instructions on any cleaning agent
prior to use to determine the cleaner’s compatability
with the surface being cleaned.
Vending Calibration:
Routine calibration is recommended every time the
unit is empty or near empty. This should be done
appromixatly once a month to insure proper
inventory. Follow steps from page 6. - Calibrate
Scale Before Loading Ice
