Installation
FAILURE TO FOLLOW INSTALLATION
GUIDELINES AND RECOMMENDATIONS MAY
VOID THE WARRANTY ON YOUR UNIT.
SELECTING A LOCATION FOR YOUR NEW UNIT
The following conditions should be considered when selecting a location for your unit:
1. Floor and Countertop Load: The area on which the unit will rest must be level,
free of vibration, and suitably strong enough to support the combined weights of
the unit plus the maximum product load weight.
2. Clearance: Clearance must be a combined total of at least 3” on all sides and
back of unit. Do not place any object that can block the ventilation exhaust from
the machine compartment register.
3. Ventilation: The air cooled self-contained unit requires a sufficient amount of cool
clean air. Avoid surrounding your equipment stand around other heat generating
equipment and out of direct sunlight. Also, avoid locating in an unheated room or
where the room temperature may drop below 55°F or above 86°F.
INSTALLATION CHECKLIST
After the final location has been determined, refer to the following checklist prior to
start-up:
1. Check all exposed refrigeration lines to ensure that they are not kinked, dented, or
rubbing together.
2. Check that the condenser and evaporator fans rotate freely without striking any
stationary members.
3. Unit must be properly leveled; check all legs or casters to ensure they all are in
contact with the floor while maintaining a level work surface. Adjusting bullet
feet heights or shimming casters may be necessary if the floor is not level. NOTE:
Damage to equipment may result if not followed. Unified Brands is not responsible
for damage to equipment if improperly installed.
4. Plug in unit and turn on main on/off power switch. The main power switch is
located in the compressor mechanical housing.
5. Allow unit time to cool down to temperature. If temperature adjustments are
required, the temperature control is located on the evaporator coil within the
refrigerated base (refer to page 10). Confirm that the unit is holding the desired
temperature.
6. Refer to the front of this manual for serial number location. Please record this
information in your manual on page 2 now. It will be necessary when ordering
replacement parts or requesting warranty service.
7. Before putting in food, allow your unit to operate for approximately two (2) hours so
that interior of the unit is cooled down to storage temperature.
8. Check doors to ensure there is proper sealing and alignment.
9. For units with self-closing doors: Check doors to ensure they open and shut freely.
Note: All motors are oiled and sealed
Note: All self-contained models are shipped from the factory with the service
valves open and ready for operation.

OM-51000 & 53000 SERIES
Installation
IT IS IMPORTANT THAT A VOLTAGE READING
BE MADE AT THE COMPRESSOR MOTOR
ELECTRICAL CONNECTIONS, WHILE THE UNIT
IS IN OPERATION TO VERIFY THE CORRECT
VOLTAGE REQUIRED BY THE COMPRESSOR
IS BEING SUPPLIED. LOW OR HIGH VOLTAGE
CAN DETRIMENTALLY AFFECT OPERATION
AND THEREBY VOID ITS WARRANTY.
IT IS IMPORTANT THAT YOUR UNIT HAS
ITS OWN DEDICATED LINE. CONDENSING
UNITS ARE DESIGNED TO OPERATE WITH
A VOLTAGE FLUCTUATION OF PLUS OR
MINUS 10% OF THE VOLTAGE INDICATED
ON THE UNIT DATA TAG. BURN OUT OF A
CONDENSING UNIT DUE TO EXCEEDING
VOLTAGE LIMITS WILL VOID THE WARRANTY.
ELECTRICAL SUPPLY
Any wiring should be done by a qualified electrician in accordance with local electrical
codes. A properly wired and grounded outlet will assure proper operation. Please
consult the data tag attached to the compressor to ascertain the correct electrical
requirements. Supply voltage and amperage requirements are located on the serial
number tag located inside the mechanical housing.
BULLET-FEET ADJUSTMENT
The legs are equipped with bullet-type leveling bolts. Turn bolts clockwise or
counterclockwise until the unit is level (both right to left and front to back). This can be
done by hand or with an open end wrench.
OM-51000 & 53000 SERIES
9
Operation
Allow unit to operate for approximately two (2) hours before placing in food.
AMBIENT CONDITIONS
This unit is designed for indoor operation in a room with maximum ambient 86°F and
55% relative humidity or less. It should never be used outside or located in direct sunlight.
Unified Brands has attempted to preset the temperature control to ensure that your
unit runs at an optimum temperature, but due to varying ambient conditions, including
elevation, food type and your type of operation, you may need to alter this temperature
using control adjustment until desired temperature is reached.
BEFORE MAKING TEMPERATURE ADJUSTMENTS
1. Make sure that you are allowing adequate time for the cabinet temperature to equalize.
When initially started or when first loaded, it can take a long time for temperatures in
the display area to stabilize.
2. Make sure that unit operation is not being effected by room ambient conditions.
(See Ambient Conditions section above). If there are any significant ambient issues,
adjusting the temperature setting may not help.
TO RAISE TEMPERATURE
1. Turn knob counterclockwise, keeping the arrow on the knob pointed within the arc.
2. Turning counterclockwise beyond the arc can result in shutting off of the compressor.
TO LOWER TEMPERATURE
1. Turn knob clockwise, keeping the arrow on the knob pointed within the arc.
2. Turning clockwise beyond the arc can result in freeze-up.
DOOR ADJUSTMENT
The doors are mounted to the cabinet with two screws on the upper hinge, and a hinge pin
on the bottom. To adjust the door, first open it to 90º and loosen the two screws enough
to reposition the door. Once repositioned, retighten all screws.

Maintenance
DO NOT USE SHARP UTENSILS AND/OR
OBJECTS.
BRUSH COIL IN DIRECTION OF FINS,
NORMALLY VERTICALLY AS TO NOT DAMAGE
OR RESTRICT AIR FROM PASSING THROUGH
CONDENSER.
DO NOT USE STEEL PADS, WIRE BRUSHES,
SCRAPERS, OR CHLORIDE CLEANERS TO
CLEAN YOUR STAINLESS STEEL.
CAUTION
DO NOT USE ABRASIVE CLEANING
SOLVENTS, AND NEVER USE HYDROCHLORIC
ACID (MURIATIC ACID) ON STAINLESS STEEL.
DO NOT PRESSURE WASH EQUIPMENT AS
DAMAGE TO ELECTRICAL COMPONENTS
MAY RESULT.
Unified Brands strongly suggests a preventive maintenance program which would include
the following Monthly procedures:
1. Cleaning of all condenser coils. Condenser coils are a critical component in the life
of the compressor and must remain clean to assure proper air flow and heat transfer.
Failure to maintain this heat transfer will affect unit performance and eventually destroy
the compressor. Clean the condenser coils with coil cleaner and/or a vacuum, cleaner
and brush. Use of any filter over the condenser coil may result in poor performance
of the equipment. The factory does not recommend any auxiliary filter be used on
the condenser coil. Any failures of the unit as a result of an auxiliary filter will not be
covered under warranty.
2. Clean fan blade on the condensing unit and evaporator assembly.
3. Clean and disinfect drain, drain lines and evaporator pan with a solution of warm water
and mild detergent.
4. Clean all gaskets on a weekly if not daily basis with a solution of warm water and a mild
detergent to extend gasket life.
5. Lubricate door hinges with lithium grease.
6. Clean drawer tracks of any debris.
7. The drawer module may be removed from the cabinet for cleaning by loosening the two
¾” round screws on rear anchor bracket. Once loosened the drawer cartridge may be
removed from the cabinet to clean the interior of the cabinet. Clean with mild soap and
warm water mixture. Re-install the drawer cartridge by properly aligning the cartridge
to the bracket and tightening the ¾” round screws.
8. Inspect all silicone seams at interior of the base cabinet on a monthly basis. Re-apply
food grade silicone sealant as needed to any seams where silicone has peeled away
or cracked. Apply silicone to a clean dry surface. Allow sufficient drying time to assure
best adhesion of sealant.

Troubleshooting
CLEANING CONDENSOR COIL
An accumulation of dirt and dust prevents the condenser coil from removing, making
your unit cool poorly, run constantly, or even stop completely if the compressor overheats.
Clean coil using a vacuum cleaner with wand attachment. If the coil is greasy, wash it with
a solution of warm water the mild detergent using a bristle brush. Take care not to drip
water onto other parts of the condensing unit.
CLEANING DRAIN AND DRAIN PAN
Clean the drain using an oven baster to force a solution of hot water and baking soda
or bleach into the drain opening. To clear a stubborn clog, insert a length of 1/4” round
plastic tubing into the drain and push it gently through to the drain pan; pull back out.
Wash the drain pan regularly with a solution of warm water and baking soda.
CHECKING THE DOOR SEAL
Open the door and examine all four sides of the door gasket for any tears. Feel the gasket
for brittleness and/or cracks. If the gasket shows damage, then it must be replaced. If
no damage is observed, close the door and check the seal between the gasket and the
cabinet for obvious gaps. Next open the door and close it on a dollar bill. Slowly pull the
dollar bill out from the door. If the gasket seals properly, you will feel tension as it grips
the bill. Repeat this test all around the door. If the gasket does not seal tightly, replace the
gasket after first checking the door for any sagging or warping.
SERVICING THE CONDENSER FAN
Inspect the condenser fan motor by removing the mechanical housing cover to gain access.
Unplug the unit. Clean the fan blade, and turn it to see if the blade rotates freely. If the
motor binds, replace it. If any damage to the blade is observed, unscrew the retaining
nut that holds the blade to the motor shaft and pull the blade off the shaft. Install a new
fan blade, replacing any washers, and tighten the retaining nut. To test the condenser fan
motor, disconnect the wires to the fan motor. Using a multimeter set at RX10, touch one
probe to each terminal. The multimeter needle should show approximately 45 to 50 ohms
resistance. A lower reading indicates the motor is faulty and needs to be replaced.
Next, set the multimeter at RX1000 and touch one probe to the motor terminals and the
other probe to any unpainted metal part of the unit. If the multimeter needle moves, the
motor is grounded and needs to be replaced. To remove the motor, unscrew the bracket
that holds the fan motor to its housing. Slide the motor out of the housing. Remove the
fan blade from the old motor and attach to the new motor, replacing any washers. Install
the new motor in its housing by screwing the bracket into place. Reattach the wires to the
motor terminals and reconnect the ground wire.

Troubleshooting
SERVICING THE COMPRESSOR
The compressor is part of the sealed refrigeration system and should be replaced by
a professional service technician. You can, however, test the compressor and certain
components. Prior to testing, unplug the unit and remove the access cover to the
mechanical housing. A small box mounted on the side of the compressor protects the
relay, overload protector, and capacitor. Release the wire retaining clip that holds the
cover in place and slip off the cover and the clip.
To test the compressor relay, pull the relay straight off the compressor without twisting
or damaging it. If the relay has an external wire coil, hold the relay so that the word
TOP is up. Using a multimeter set at RX1, place the probes on terminals S and M. The
multimeter needle should not move. Remove the probe from terminal M and place it on
the side terminal marked L. The multimeter needle should not move. Remove the probe
from terminal S and place it on terminal M. The multimeter needle should sweep across
the scale, indicating full continuity.
Turn the relay upside down. Using a multimeter set at RX1, place the probes on terminals
S and M. The multimeter needle should sweep across the scale, indicating full continuity.
Remove the probe from terminal M and place it on the side terminal marked L. The
multimeter needle should sweep across the scale, indicating fully continuity. Remove the
probe from terminal S and place it on terminal M. The multimeter needle should not move.
If the relay fails any of the tests listed above, the relay is faulty and needs to be replaced.
Push a new relay onto the compressor terminals and replace the terminal cover. If the
relay passes all the tests listed above, proceed to testing of the overload protector.
To remove the overload protector, use a screwdriver to gently pry open the circular spring
clip that secures the overload protector to the compressor and snap out the overload
protector. Pull the two wire connectors off the terminals. Using a multimeter set at RX1,
touch a probe to each overload protector terminal. The multimeter needle should sweep
across the scale, indicating full continuity. If the overload protector passes this test,
proceed to testing of the compressor. If the overload protector fails this test, the overload
protector is faulty and needs to be replaced. Reattach the push-on connectors to the new
overload protector, clip it in place on the compressor, and replace the terminal cover.
For testing the compressor, use a multimeter set at RX1 to test each of the three terminal
pins against each of the other two terminal pins. Each pair should show continuity. Then,
with the multimeter set at RX1000, place one probe against the metal housing of the
compressor (if necessary, scrape off a small amount of paint to ensure contact with
bare metal). Place the other probe on each of the three terminals in turn. If any of the
three terminals shows continuity with the housing, the compressor is grounded. If the
compressor fails either test, call for service at 888-994-7636. If the compressor passes
the tests, reinstall the overload protector, relay, terminal cover, and mechanical housing
cover.
