GENERAL INFORMATION
Introduction
The information contained in this manual
pertains to the self-contained open display
merchandisers: OMC-LB, OMC-36, OMC-48,
OMC-72, and OMCSL48. These merchandisers
are ideal for showcasing prepackaged food
products in a safe manner. These display
coolers were designed to operate in an airconditioned store where the temperature is
maintained at 75°F or lower and the relative
humidity is 55% or lower.
Inspection
These display coolers were carefully factorytested, inspected and properly packed to
ensure delivery in the best possible condition.
The equipment should be uncrated and
checked for damage immediately upon
delivery. ALL CLAIMS FOR DAMAGES MUST BE
FILED WITH THE TRANSPORTATION COMPANY NOT WITH ZERO ZONE. The carrier will supply
necessary report and claim forms.
Location
Position the OMC-LB and OMC units at a
minimum of 3-1/2” from walls and other objects
that may impede the circulation of air around
the exterior of the case. The wall bumper stops
supplied for the rear of the OMC-LB and OMC
coolers must always remain attached. The
OMCSL48 is designed for placement within a
lineup of gondola shelving and does not require
wall bumper stops.
Do not locate this equipment where it will be
exposed to the direct rays of the sun or near a
source of radiant heat.
Do not install the display case near doors or
areas exposed to air currents.
Do not stack cartons or packaging around the
unit that might restrict air circulation to and from
the air-cooled condensing unit.
FAILURE TO OBSERVE THIS MAINTENANCE
PROCEDURE COULD CAUSE A SIGNIFICANT
DECREASE IN REFRIGERATION PERFORMANCE
AND INCREASED RUNNING COSTS.
Installation
OMC-LB, OMC-36, OMC-48 and OMC-72
merchandisers must be taken off of the shipping
skid and plugged into the proper electrical
receptacle. Additionally, because of its shallow
profile, the OMCSL48 must be anchored to the
shelving uprights or similar support using the
brackets shipped with the unit.
OPERATION
Operation
Table 1 on page 4 lists the case model with
power and electrical receptacle requirements.
The power switch on the OMC and OMC-LB is
located behind the lower front air grill. On the
OMCSL48 the power switch is located behind
the light box, accessible over the top of the
cabinet. The power switch should be off before
plugging or unplugging the case. Initially, the
evaporator and condenser fans (one on the
OMC-LB & OMC-72) will run without the
refrigeration compressor(s). After a delay of two
minutes, the compressor(s) will start and the
case will begin to cool.
All stock must enter the cabinet pre-chilled.
Do not operate with lower rear vent panel
removed. This panel has been specifically
designed to disperse moisture from the drain
tank.

Drains
It is important that the condensate drainage
system be kept clear of any obstructions.
Obstructions can be in the form of foreign
objects such as loose stock items, dislodged
price tags, product labels, etc. Because this
cabinet circulates refrigerated air, the entrance
of environmental borne dust particles is
inevitable. These particles can accumulate in
the drainage system and eventually form
sludge.
Condensate water drains into a tank, which is
designed to evaporate the water. To remove
the tank, switch off the power supply, remove
the lower front air grill, unplug the electrical
socket and slide the tank out the front of the
cabinet.
WHEN CLEANING, THE TANK SHOULD NOT BE
IMMERSED IN WATER, AS ELECTRICAL
COMPONENTS COULD BE DAMAGED
It is recommended that the condensate
drainage system be thoroughly cleaned on a 6month basis. The need for this may be more
frequent, depending on environmental
conditions.
Refrigeration
All OMC cases are supplied with a selfcontained refrigeration system. The units are
factory charged with POE oil and R404a
refrigerant.
Refrigerant charges are as follows:
OMC-36 3.86 lbs
OMC-48 4.40 lbs
OMC-72 (2) 3.86 lbs ea.
OMC-LB 3.86 lbs.
OMCSL48 5.00 lbs.
All valves and adjustments to the refrigeration
system have been preset for operation by the
factory. No additional adjustments are
necessary once the case is installed.
To protect the compressor from damage, the
condensing unit is supplied with a low-pressure
safety cut out and a high-pressure safety cut
out. The low-pressure cut out is self-resetting and
has a non-adjustable setting of 5 PSIG. The highpressure cut out is manually reset (see service
section), and has a non-adjustable setting of
410 PSIG.
High Pressure Cut-Out
On the OMC and OMC-LB, the high pressure
cut-out is located adjacent to the condenser
coil, behind the lower front air grill. To access
the control, remove the lower front air grill by
lifting up and away from the cabinet. To reset,
press the red button on the control. The highpressure control is set at 410 PSIG located in the
discharge line. On the OMCSL48, the control is
located on the side of the electrical box on top
of the cabinet behind the light box. This is
accessible from the top of the cabinet.
Temperature Control
A microprocessor controller is mounted behind
the lower front air grill and is accessed by
removing the air grill on the OMC-LB, 36, 48 and
72. The controller for the OMCSL48 is located on
the electrical box behind the light box,
accessible over the top of the cabinet.
This controller has many functions including a
temperature control and a defrost control. It
has been factory set for your application and
has different factory settings for various product
applications.
If you want to change the case operating
temperature, a qualified refrigeration technician
will be able to change the set points. There are
different operating temperatures depending on
which product is to be displayed in the case.
There are three general product operating
temperature options offered in
descriptions include; Meat, General Purpose
(Factory Setting), and Fresh Cuts.

other parameters in the case. Figure 3 lists
descriptions of the main alarm signals.
Thermometer
The thermometer is mounted at the left-hand
lower front of the case. This allows the customer
and operator to read refrigerated air
temperature. Allow a minimum run time of 1
hour to achieve accurate temperature
readings.
Electrical
Figures 4-8 show typical wiring diagrams. The
light switch for the sign of the OMC and
OMCSL48 cases is on top of the unit. The light
switch for the OMC-LB case is located on the
bottom of the light box.
Defrost
The OMC case has an automatic defrost
control, which has been factory set. The defrost
cycle is every 4 hours and terminates on
temperature. The case uses off cycle air defrost.
The compressor is turned off and the evaporator
fans continue to run to melt frost from the coil.
The condenser fans (1 fan on OMC-LB and 72)
run during defrost except the OMCSL48
condenser fan, which does not run during
defrost.
USER INFORMATION
Cleaning
The condenser fins on the OMC, OMC-LB and
OMCSL48 cases must be cleaned a minimum of
every 3 months.
Remove the lower front air grill by lifting up and
away from the cabinet. Remove dust and lint
using a brush or vacuum cleaner. Replace grill.
On the OMCSL48, the face of the condenser is
behind the light box, accessible over the top of
the cabinet, which makes it always available for
routine cleaning. No disassembly is required for
this unit.
FAILURE TO OBSERVE THIS MAINTENANCE
PROCEDURE COULD CAUSE A SIGNIFICANT
DECREASE IN REFRIGERATION PERFORMANCE,
COMPRESSOR DAMAGE AND INCREASED
RUNNING COSTS.
To allow the refrigeration system to operate
efficiently, the OMC and OMC-LB cabinets
should be positioned with a minimum of 3-1/2”
clearance from the rear wall. The wall bumper
stops supplied for the rear of these units must
always be attached to maintain this spacing.
The OMCSL48 does not require a wall bumper
for proper performance.
The cooler should be thoroughly cleaned before
start-up and routinely thereafter to maintain a
clean appearance. Use mild detergent (NEVER
AN ABRASIVE CLEANER) and warm water to
wipe out the inside of the cooler. Clean all glass
with glass cleaner. The cooler will remain bright
and sparkling with just a few minutes of cleaning
each week. The case drain should be regularly
cleared of debris and price tags.
NOTE: Do not use high-pressure water or steam
to clean the interior.
Shelving
All OMC units have adjustable height shelves,
which can be mounted horizontally or angled
downward at front. When replacing shelves,
ensure that the rear of the shelf is locked into the
recess in the shelf bracket.
Loading
When loading the display case, the following
points must be taken into consideration:
Do not exceed the load limit as marked on
•
the case.
When restarting the display case after a
•
prolonged shut down, the case should be
left to operate empty for at least one hour
before loading with pre-cooled product.
3
OMC-LB, OMC-36, OMC-48, OMC-72, OMCSL48
03035
Leave space between the stock to allow the
•
refrigerated air to circulate.
The air inlet at the lower front of the case
•
and back wall or front grill discharge should
never be obstructed.
Product with a temperature higher than the
•
display case should not be introduced.
SERVICE
Expansion Valve
All OMC cases have an evaporator coil located
below the bottom coil cover. The OMC and
OMCSL cases also have an evaporator coil
located behind the perforated rear wall. Each
coil has its own expansion valve set for 15-20°F
superheat. Bottom TXV superheat should be
lower than top superheat.
Lamps
The lamps are located behind the sign. Before
servicing the lamps, turn off the lamp switch.
The lamps in the OMC-LB and OMC cases are
accessed by removing the screws on the top of
the case and rotating the sign forward. Rotate
the sign slowly to expose the lights. The lamps
on the OMCSL48 can be serviced by removing
the retaining bracket at the top front of the light
box and sliding the sign up and out of the box
channel.
