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

the MODE key in the ‘RUN’ position and the

DOORS key in the ‘LOCK’ position.

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.

http://www.leerinc.com/ice-

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
