Start-UP
Storage and Transportation:
The merchandiser should be stored and
transported in an upright position. It is not
recommended to tilt the merchandiser. If the
merchandiser is tilted beyond 45° of vertical, oil
may drain from the compressor causing premature
failure.
Do Not stack merchandisers on top of one another
due to risk of falling. Falling merchandisers could
result in damaged units or serious injuries. It is
recommended to use warehouse racking design to
accommodate the weight of the merchandisers
and prevent falling.
Packaging:
Prior to installation, the outer packaging on the
merchandiser will need to be removed. The
majority of the packaging materials can be
recycled and disposed of in an environmentally
friendly manner. Glass door models are shipped
with door support brackets installed between the
merchandiser's door opening(s) and the bottom
rail of the door. These support brackets must be
removed prior to operation of the merchandiser.
Failure to remove the brackets will affect the seal
of the door gasket to the cabinet face.
Installation
Note: Leer Ice Merchandisers are commercial in
design and not intended for residential use
Placing Merchandiser:
When placing the merchandiser, allow a minimum
of 3 inches of air space from all surfaces 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. On outdoor auto-defrost
models, the 3-inch space behind the merchandiser
will also help ensure that the evaporator drain
tube, which exits the back wall, is not being
restricted during the defrost cycle. For Pallet
Load Front Units see the special instructions at
the end of this manual.
Merchandiser Leveling:
The merchandiser installation location should
have a solid, level base. If the merchandiser is
exhibiting a slight forward lean, the front of the
cabinet should be blocked to bring the cabinet to a
level position. A forward lean may affect proper
draining of the unit cooler assembly during the
defrost cycle.
Electrical:
Warning! Component parts shall only be
replaced with like components. Electrical work
and servicing should be done by licensed
professionals. Disconnect power before
performing service, certain models may
contain multiple voltages. Leer does not
assume responsibility for any damage to people
or things deriving from violation, improper use
or in any case not in compliance with Leer’s
instructions.
The Merchandiser must be plugged into a
dedicated and properly grounded 115V/60hz/1Ph
circuit with a circuit fuse or breaker rated at a 15
or 20 Amps depending on model. The electrical
service connections to the merchandiser must be
compliant with the National Electric Code and
any local codes that may apply. DO NOT use
extension cords. Models that come with the 20
Amp plug configuration should not be removed.
Models covered in this manual come with a main
power switch. 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 into the ON position. The light fixture
should start immediately when power is applied.
After a 2-minute delay, the compressor and the
condenser fans should start if a defrost is not
required. The evaporator fans will start once if the
evaporator temperature is under 75 degrees. The
condensing unit will continue to run until the air
temperature in the cabinet reaches +16° 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
cause the circuit breaker to trip and/or may cause

5
voltage drops. As a result, the power to the
merchandiser may be interrupted and freezing
performance can be adversely affected which may
cause equipment damage and /or product loss.
Voltage supply to the merchandiser must not vary
more than ±10 percent of the normal 115V.
Information regarding the electrical voltage and
frequency being supplied to the merchandiser can
be found on the merchandiser’s serial data plate
typically located at the upper left corner of the
merchandiser’s interior. Information regarding the
maximum fuse/circuit breaker size required for
the specific model is available from the
condensing unit data plate.
Plug Units:
Units that have a plug style condensing unit and
evaporator will need to be unpackaged and
installed on top of the unit. The completed plug
weighs approximately 150 pounds. An
appropriately rated, mechanical lifting device
should be used to prevent injury. If one is not
available and due to the weight of the plug unit, it
is recommended to use a two person lift to
manually install. Use caution to prevent damage
to the drain pan nipple upon installation. Do not
lay the evaporator housing directly on any surface
as the weight of the compressor could damage the
fans or drain nipple. Once installed, lighting, door
switch connections (if applicable) and grounding
will need to be made on top of the unit.
Condensate Evaporator:
Indoor auto-defrost models are supplied with a
condensate evaporator heater assembly which is
packaged and shipped inside the merchandiser. It
will require simple installation by the consumer
(see Figure 1). A separate copy of this instruction
sheet is supplied with the condensate evaporator
assembly.
The condensate evaporator assembly contains a
drip pan to collect water generated by the
merchandiser’s defrost cycle and a heat element to
evaporate the water. Once energized, the heat
element in the condensate evaporator assembly is
continuously generating heat. The merchandiser is
to 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 which allows for heat dissipation away
from the surface of the wall. The main power cord
should also be routed to avoid pinching.
Note: Do not operate an indoor auto-defrost
merchandiser without having a condensate
evaporator assembly installed under the
evaporator drain tube exiting the back wall of the
cabinet. Failure to install this assembly will result
in water draining directly onto the floor during the
defrost cycle. This may result in water damage to
the floor and create a hazardous slip condition in
the area surrounding the merchandiser.

•Fan “ON” - Certain models that utilize the
XRO6 controller have the capability to
operate the evaporator fans on and off
independently from the defrost circuit.
•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 3 seconds.
Note: Manual Defrost will not initiate unless the
unit is at standard operating temperatures and the
evaporator probe is under the defrost termination
setting.
Electronic Control Operation:
The electronic control combines the functions of
both the mechanical thermostat and defrost timer
into a single control. The control also offers the
consumer the capability of monitoring the
operational status of the merchandiser via the icon
and digital temperature display (located on the
face of the control). The controller has been
programmed by Leer to operate the merchandiser
within the design parameters of the refrigeration
system. The set-point (cut-out) for these controls
has programmed parameters for 14-16°F, with a
differential of 6-8°F Should the user desire to alter
the Set-Point, the new set-points should not
exceed +/- 4° of the original factory setting. Do
not alter any of the programming parameters in
the controls without first consulting with Leer.
Auto-Defrost Control:
The AD control is located under the condensing
unit cover and contains two thermal-couple probe
wires. 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 Red 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 merchandiser at that location.
During the normal operation of the control, the
digital display will show the cabinet temperature
at the probe “P1” location. The Black 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.
Electronic Control Startup:
Turn the switch if equipped into the ON position.
After a 2-minute delay, the compressor and the
condenser fan should start. The light fixture
should start immediately when power is applied.
After a 2-minute delay, the compressor and the
condenser fans should start. The evaporator fans
will start once if the evaporator temperature is
under 75°F. The condensing unit will continue to
run until the air temperature in the cabinet reaches
+14-16°F.
Note: If a defrost is required upon startup the
controller will enter defrost mode after the 2-
minute delay. Normal operation will resume upon
defrost termination and a short drip time.
Possible Displayed Alarm Codes:
“P1” – Air Probe failure: The control will
override the “P1” functions and cycle the
compressor at preset time 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
temperature for a period exceeding a preset time.
The alarm will continue to display until the
cabinet temperature drops below maximum levels.

7
“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/
Loading Ice:
The merchandiser should be pre-chilled prior to
loading with ice. Pre-chilling will aid the
merchandiser in reaching storage temperature at a
faster rate once loaded and reduce the risk of
melting product. Do not over fill the merchandiser
with ice!
Auto-Defrost: 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. This 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.
Maintenance and Service
Danger! This unit is charged with R290
(propane refrigerant). Propane is a flammable
and explosive gas. Component parts shall only
be replaced with like components.
Maintenance and repair of the electrical and
refrigeration systems should only be done by
licensed, trained and qualified personnel.
Disconnect power before performing service.
Certain models may contain multiple voltages.
Leer does not assume responsibility for any
damage to people or things deriving from
violation, improper use or in any case not in
compliance with Leer’s instructions.
Cleaning the Merchandiser:
The merchandiser should be cleaned annually. In
corrosive environments such as coastal regions
and areas where deicing chemicals and road salts
are used, more frequent cleaning is recommended.
The exterior of the merchandiser 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 merchandiser. If
cleaning the interior of the merchandiser, 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 merchandiser.
Cleaning Door Gaskets:
Door gaskets may mildew and stiffen over time.
The gasket is made of a soft, flexible rubber-like
material that 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.

8
Cleaning Condenser Coils:
It is recommended to inspect and clean the
condenser coil and fan blades every 3 months.
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.
WARNING: When using compressed air, there
may be a cloud of dust released into the air
surrounding the machine.
It is recommended that the service person wear
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 Merchandiser:
Auto-Defrost models are equipped to be self-
defrosting and enter defrost mode once every four
hours automatically. During the defrost cycle, the
power to the refrigeration system will be
automatically re-directed to the defrost circuit.
This will shut down power to the condensing unit
and evaporator fan motors and also send power to
a heat element that is attached to the surface of the
evaporator coil. The heat generated by the
element will melt the ice build-up on the
evaporator coil and the resulting melt water will
drain through a tube out of the back wall of the
merchandiser.
On outdoor cabinet models, the melt water will
exit the drain tube directly to the ground.
On indoor cabinet models, the consumer needs to
install the condensate evaporator heater assembly
(described in the Installation section of this
manual) onto the exterior back wall of the cabinet.
The melt water from the defrost cycle will drain
into a catch pan where it will then be heated to the
point of evaporation. The function of the
condensate evaporator’s heat element should be
checked routinely. Failure of the element could
result in an over-flow condition for the assembly’s
drain pan. A simple check of the heater would be
a touch test of the surface temperature of the
assembly’s housing. The condensate evaporator’s
heat element is energized continuously so the
surface of the housing should always be hot to the
touch. If testing the heat element with a meter, the
element can be unplugged from its’ power source
and a resistance reading can be taken through the
plug’s bladed terminals. The condensate heater is
rated to generate 125 watts of power, which
translates to approximately 106 ohms of
resistance.
Auto-Defrost Electronic Control:
The control is factory set for a 24 minute defrost
cycle to occur at 4-hour intervals. Like a
mechanical defrost timer, the electronic control
will switch power from run mode (condensing
unit and evaporator fans) to defrost mode (defrost
heat element). Whereas a mechanical timer
operates strictly on a timed cycle, the duration of
the electronic control’s defrost cycle is controlled
by the temperature at the sensor probe “P2.” If the
temperature at this probe reaches 60-65°F prior to
the 24-minute timed cycle ending, the control will
override the timed cycle and immediately switch
power from the defrost mode to a drip time then
standard run mode. If temperature is not reached
at probe “P2,”the defrost cycle will continue for
the entire 24- minute programmed cycle prior to
returning to run mode. Energizing the defrost
circuit in the electronic control can be verified
with the illumination of the “melting snowflake”
and the letters “dE” appearing on the control’s
display.

9
The electronic defrost circuit is equipped with a
defrost termination safety switch and is attached
to one of the evaporator coil tubes (located inside
the Unit Cooler Assembly). This switch senses
temperature and will cut power to the defrost heat
element should the temperature at the surface of
the switch reach 100° F. This switch only
terminates power to the heat element and will not
end the timed / temperature defrost cycle. Once
the merchandiser has returned to run mode, the
termination safety switch will re-set when the
temperature at its’ surface reaches 70° F.
Warning! The defrost termination safety switch
functions as a possible fire protection device. Do
not remove or by-pass the switch from the defrost
circuit.
Note: If an electronic control AD unit loses power
and the temperature at “P2” is less than 60°F, it
will automatically enter a defrost cycle after a
two-minute delay.
Glass Door Models and Maintenance:
The glass door is designed for use on indoor units
or in a controlled environment. It is constructed
with a non-heated, triple-pane glass-pack, with
both inner and outer panes being tempered. To
avoid possible condensation on the outer surface
of the door, case temperature in the merchandiser
should be maintained near its’ designed set-point
of 16°F +/- 4° and ambient dew-points around the
cabinet location should be kept below 60°F. Any
household glass cleaner can be used to clean the
surface of the door. The glass door’s gasket is a
rubber bellows-style magnetic gasket. The
replacement gasket has an insert dart that installs
into a retaining slot in the door frame. The gasket
can be started in-place with light hand pressure,
followed with mild impact pressure applied with a
dead-blow hammer to ensure that the legs of the
dart penetrate fully into the slot. During
replacement, set the gasket at the 4-corners of the
door first to reduce stretching. If the door gasket
appears to be in good condition but is failing to
seal to the surface of the cabinet, both the spring-
load tension and adjustment of the hinges should
be checked.
Solid Door Models and Maintenance:
Cabinets designed for outdoor use will have a
metal clad door that has been insulated with the
same urethane foam insulation as the cabinet.
The exterior metal is stucco embossed to hide
minor impacts and is coated with a fluorocarbon
paint system. This paint system was designed to
withstand years of outdoor exposure. For routine
cleaning of the door’s exterior surface, a mild
detergent diluted in warm water should be
adequate.
Hinge Spring Tension:
A simple test of the spring-load tension is to open
the door just enough to insert two fingers between
the surface of the cabinet and the handle side of
the door. When the fingers are withdrawn, there
should be enough tension set on the hinge spring-
loads to slowly move the door to a closed
position. If the door does not move from this two-
finger location, it’s likely that either the spring-
load requires re-tensioning or lubrication. If the
door moves part way from the two-finger location
but stops short of the cabinet, the compression of
the gasket along the hinge side of the door should
be checked. If there is too much compression, the
door will bind when closed and should have its
hinge-mount location checked and possibly
adjusted. Removing the hinge covers will expose
the spring-loads for tension adjustment or
removal. Removal of the spring-load will expose
the hinge-adjustment plate and mounting screws
should hinge adjustment be required. See Figure
2for instruction regarding spring-load installation
and adjustment.
Decaling Recommendations Solid Door:
a) Use a decal with a 2-mil cast vinyl
substrate. Cast vinyl contains less
memory than a calendared vinyl or a
polyester substrate and will conform to the
embossed surface with the least amount of
stress on the decal’s adhesive.
b) The decal’s adhesive should have a
minimum peel-strength rating of 80 oz.
/inch.

10
c) Clean the surface of the door with
isopropyl alcohol and either air dry or dry
with a clean cloth.
d) Heating the surface of the door
immediately before applying the decal will
aid the adhesive bond of the decal. Never
apply a decal to a surface that is colder
than 50° F.
e) Use a soft roller or plastic squeegee to
apply the decal and press it into the
embossed surface of the metal. Applying a
small amount of heat to the surface of the
decal will aid in this process.
Door Gaskets and Hardware:Routine
inspection of the door gasket seal and the action
of the door’s hinges are recommended. If damage
has occurred to the gasket, it may allow outside
air to penetrate the cabinet and the gasket should
be replaced. The upright solid door utilizes the
same hinge as the glass door. Leer solid doors
have a barbed dart that inserts into a slot opening
in the surface of the door frame. See Figure 3 for
instructions on solid door gasket replacement.
R290 Refrigeration Service:
Danger: Do not attempt to open the
refrigeration system! Propane is a flammable
and explosive gas.
Like other refrigeration systems, a unit charged
with R290 is not serviceable on a consumer level.
Experienced technicians can contact Leer for an
in-depth service and guideline manual. The use of
special tools and proper procedures performed by
licensed, trained and qualified professionals is
required.
R290 General Information:
R290 refrigerant is flammable, but the amount of
refrigerant used is relatively small and the chance
of ignition in the event of refrigerant leak is
extremely low. Millions of commercial and
residential refrigeration products are already using
similar, if not exact, refrigerants worldwide.
R290 refrigeration grade propane has a much
higher purity than standard propane. The higher
moisture content of standard propane will damage
a refrigeration system. Standard propane also has
a scent added (another impurity) that refrigeration
grade materials do not.
R290 is a high-performance refrigerant. The
superior thermodynamic properties of R290
compared to R404a and R134a allow for a
reduced charge per system and lower system
energy use.
Most important, It’s eco-friendly! R290 is
classified as a hydrocarbon (HC) refrigerant,
which is a natural, non-toxic, refrigerant and the
top alternative to hydrofluorocarbon (HFC)
refrigerants. R290 has an Ozone Depletion
Potential (ODP) of 0 and an ultra-low Global
Warming Potential (GWP) of 3.

Solid Door Magnetic Gasket Replacement Instructions:
1. Position solid door on a flat non-abrasive surface, exterior side down.
2. Remove old gasket by grasping firmly at the corner and pulling away from the door frame extrusion.
3. Inspect the extruded slot to insure there are no particles to interfere with the new gasket installation.
4. Align new gasket with door corners and use thumb to press into frame.
5. Start at one corner of the frame and begin pressing the new gasket into the slot. Using a non abrasive
tool such as a hammer head works well for this application. Apply downward pressure while moving
along the permeter of the frame. Excessive pressure may strech the gasket and cause bulging at the
corners.

Merchandiser, Tall and Deep or Pallet Load.
It is recommended to place the PLF on a solid -
level surface.
It is recommended to use the supplied aluminum
back stop, and have it securely fastened to the
floor at least 4” away from any obstruction.
Having the unit set against the backstop will help
prevent movement during the loading process.
Attach the condensate pan to the back of the unit
at this time.
To move the unit, Insert an empty base pallet into
the lift channels. Lift the unit with a pallet jack by
the base pallet.
Move the box into place firmly against the
aluminum back stop. Lower the pallet jack and
remove the base pallet.
The unit has a rubber gasket that will seal the unit
from the outside.
Do not move the unit without the aid of a pallet
jack. Doing so will cause damage to the gasket.
Remove the lift channels before putting the unit
into operation. The lift channels are secured using
8, ½” drive bolts. Reinstall bolts to hold
aluminum trim pieces.
Retain the lift channels for use later.
Loading:
Place the pallets of ice directly on the base pallets.
Align the base pallet and ice with the aluminum
trim. Push the ice into the unit using a pallet jack.
Lower the pallet and remove the jack.
Close the doors and latch the right side.
