Start-UP
Storage and Transportation:
The freezer should be stored and transported in an
upright position. It is not recommended to tilt the
freezer. If the freezer is tilted beyond 45 degrees 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
freezer 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 underside of
merchandiser with hex-headed screws and will
require the use of a 3/8" hex-socket for screw
removal.
Installation
Freezer Placement: When placing the freezer,
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 freezer will also help ensure that the
evaporator drain tube, which exits the back wall, is
not being restricted during the defrost cycle.
Freezer Leveling: The freezer installation
location should have a solid, level base. If the
freezer is exhibiting a slight forward lean, the front
of the cabinet should be blocked to bring the cabinet
to a level position. On auto-defrost models, a
forward lean may affect proper draining of the unit
cooler assembly during the defrost cycle.
•Leveling Kit (4 pc.) No. 5350029, which is
compatible for use on most cabinet models,
is available.
Contact the Merchandiser Sales Department at Leer,
Inc. for additional information.
Electrical:
Warning! Component parts shall only be
replaced with like components. Electrical and
servicing should be done by licensed
professionals. Disconnect power before
performing service. Certain models 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 freezer 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 freezer must be compliant with
national electric code and local codes that may
apply. DO NOT use extension cords. The 20 Amp
plug configuration, that some models come with,
should NOT be removed. Some models are
equipped with a main power switch. If so equipped,
make sure the switch is in the OFF position before
plugging the freezer into the outlet. Plug the freezer
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
light fixture should start immediately when power is
applied. The evaporator fans are set to operate only
if the evaporator coil temperature is <75℉. The
condensing unit will continue to run until the air
temperature in the cabinet reaches -12°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 voltage drops. As a
result, the power to the freezer 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% of the normal 115V.

4
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.
Condensate Evaporator: Indoor auto-defrost
models are supplied with a condensate evaporator
heater assembly which is packaged with instructions
and shipped inside the freezer. 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 freezer’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 freezer 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 freezer.

•To initiate a manual defrost cycle: press and
hold the “Manual Defrost Key”for more
than 2 seconds.
Note: Manual Defrost will not initiate unless the
unit is at standard operating temperatures.
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 freezer via the icon and
digital temperature display (located on the face of
the control). The controls have been programmed
by Leer to operate the freezer within the design
parameters of the refrigeration system. The set-
point (cut-out) has programmed parameters for -12°
F, with a differential of 6° 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 freezer 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.
Possible Displayed Alarm Codes:
“P1” – Air Probe failure: The control will override
the “P1” functions and cycle the compressor for 17
minutes, 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 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.

Loading Product: The freezer should be pre-
chilled prior to loading with product. Pre-chilling
will aid the freezer in reaching storage temperature
at a faster rate once loaded and reduce the risk of
melting product.
Do not over fill the freezer! Leave room for air
flow. Do not stack product 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.
If the unit has air ducts, avoid stacking product
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

6
cold air throughout the cabinet which may result in
warm spots.
Condenser Fan Pressure Switch:
Some freezer units, to maintain proper system
operation, may be equiped with a pressure switch
that operates the condensing unit fan.
Maintenance
Note: Component parts shall only be replaced with
like components. Maintenance and repair of the
electrical and refrigeration systems should only be
done by 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 Freezer: The freezer 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 freezer 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 freezer. If cleaning the interior of the
freezer, 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 freezer.
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.
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. Debris are 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 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 Freezer:
Auto-Defrost cabinet models are equipped to be
self-defrosting and are designed to automatically
enter defrost mode once every four hours. 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 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

7
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.
It is recommended to check the operation and
condition of the evaporator coil and for signs of
excessive ice buildup every 3 months
Auto-Defrost Electronic Control: The AD
freezer comes equipped with an electronic control
(as described in the OPERATION section of this
manual). The timer is factory set for a 24 minute
defrost cycle to occur at 4-hour intervals. Like a
mechanical timer, the electronic control will switch
power from run mode (condensing unit and
evaporator fans) to defrost mode (defrost heat
element). Whereas the 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° prior to the
24-minute timed cycle ending, the control will
override the timed cycle and immediately switch
power from the defrost mode to the 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 screen.
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,
it will automatically enter a defrost cycle.
Note: Certain models may contain a drain line
heater to prevent ice from forming inside the drain
tube.
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. For routine
cleaning of the door’s exterior surface, a mild
detergent diluted in warm water should be adequate.
Routine inspection of the door gasket seal is
recommended. If damage has occurred, replace the
gasket.
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

8
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 2
for instruction regarding spring-load installation and
adjustment.
SPRING CARTRIDGE INSTALLATION INSTRUCTIONS
Figure 1 Figure 2 Figure 3
1) Install No. 220 Hinge with Adjustment Plate.
2) Assemble Spring Cartridge. Grease bushing end of pin prior to insertion into Stationary Bushing. Apply a
small amount of grease to the hinge-pin hole on the end of the Adjustment Collar Assembly. (Fig. 1).
3) Place Thrust Washer and Stationary Bushing over square pin in the Hinge and insert the Adjustment Pin into
the Adjustment Collar. Using the Adjustment Pin, compress the Spring and place the Adjustment Collar over
the round pin (Fig. 2).

9
4) Using the Adjustment Pin, turn the Adjustment Collar until the Pin contacts the Hinge. Then insert the Stop
Pin in hole of Adjustment Collar (Fig. 3). CAUTION: The Stop Pin must fully seat on Adjustment Collar.
Failure to do so may cause the Stop Pin to become dislodged. Inserting the Adjustment Pin more than halfway
thru the Adjustment Collar can cause partial push out of the Stop Pin. Repeat adjustment until desired tension is
reached. The maximum tension is 6 holes or approximately 1-1/4 turns.
5) Install Cover on Hinge.
WARNING: Use safety glasses when installing and adjusting spring tension.

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.
