CAUTION: THIS UNIT CONTAINS R290 FLAMMABLE REFRIGERANT. USE CAUTION
WHEN HANDLING MOVING AND USE OF THE REFRIGERATOR OR FREEZER.
AVOID DAMAGING THE REFRIGERANT TUBING OR INCREASE THE RISK OF A
LEAK.
WARNING: FAILURE TO FOLLOW INSTALLATION GUIDELINES AND
RECOMMENDATIONS MAY VOID THE WARRANTY ON YOUR UNIT.
WARNING: 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.
THE DANFOSS CONTROLLER HAS LOW VOLTAGE PROTECTION AND WILL
NOT OUTPUT VOLTAGE TO THE COMPRESSOR IF VOLTAGE IS LESS THAN
104V.

SELECTING A LOCATION FOR YOUR NEW UNIT
The following conditions should be considered when selecting a location for
your unit:
1. Floor 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. All casters must be in contact with the floor
to support the weight. Casters may require shims in order for the caster to be
in contact with the floor. NOTE: If there is a question pertaining to weight load
limits, consult the factory at 1-888-994-7636.
2. Clearances: Unit shall have a clearance of 0 inches at the top, 0 inches at
the rear and 0 inches at each side.
3. Ventilation: The air cooled self contained unit requires a sufficient amount
of cool clean air. Avoid surrounding your unit 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 70° F (21°C) or above
86°F (32°C). Do not place any object that can block the ventilation exhaust
from the machine compartment register.
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 or rubbing against any steel.
2. Check all visible components for any potential damage.
3. Check that the condenser fan rotates freely without striking any stationary
members.
4. Unit must be property leveled; Check all legs or casters ensure they all are
in contact with the floor while maintaining a level work surface. Adjusting
bullet feet height 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.
5. Plug unit into power source. Unit will come on. If unit does not turn on, refer
to controller operation section of this manual to manually turn on the unit.
6. Allow unit time to cool down to holding temperature. If temperature
adjustments are required, the control is located on the front panel. Confirm
that the units is holding the desired temperature.
7. If unit has drawers, check drawer to ensure the drawer slides freely and fully
extents along with seating in the cabinet properly when closed.
8. Refer to the front of this manual for serial number location. Please record
this information in your manual on page 1 now. It will be necessary when
ordering replacement parts or requesting warranty service.
9. Allow your unit to operate for approximately 45 minutes before putting in
food in the rail. Allow 2 hours for base of the unit to cool down to storage
temperature, prior to loading product. NOTE: All motors are oiled and sealed.
ELECTRICAL SUPPLY
The 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 on the rear interior wall.

3 OM-RCS-24 SERIES CHEESER STATION
INSTALLATION TO MAKELINE
1. The Cheeser Station is designed to be adjacent to the existing preparation table
or makeline and for operation efficiency, provides a refrigerated preparation
area for cheesing pizzas.
a. Model RCS-24-WS (shown above, image of Cheeser Station may vary
from actual equipment received) includes an integrated weigh scale
to measure proper cheese volumes. In addition to easier access to the
cheese, excess spillage returns back in the refrigerated supply bin.
b. Model RCS-24 does not include the integrated weigh scale but still allows
for easier access to cheese, and spillage returns back into the refrigerated
supply bin.
2. Determine the location of the Cheeser Station and move into position above
image shows the Cheeser Station on the left for left-to-right operation).
INSTALLATION OF RCS-24 RACK ASSEMBLY
1. Insert cheese bin inside the refrigerated cold-well. The bins slanted wall
should be placed towards the back.
2. Set the rack support assembly in the cold-well opening with the front support
channel over the front part of the opening.
3. Place wire rack into the support assembly.
INSTALLATION OF RCS-24-WS WEIGH SCALE PLATFORM

Cleanout Port Extension Cleanout Port Valve
MORNING STARTUP OF PREP RAIL
1. Unit cleaning may be performed at this time.
2. Turn on unit. See item #2 under the Refrigeration Control section above for
powering on the rail.
3. Allow a minimum 45 minutes for your unit to cool down before loading product.
A uniform frost pattern will appear on side walls and bottom of prep rail area.
4. Load the product and proceed with food preparation. NOTE: Product entering
unit must be at 35°F +/- 2°F.
NIGHTLY SHUT DOWN OF PREP RAIL
1. Remove product from unit at the end of the day’s preparation.
2. Turn off unit. See item #3 under the Refrigeration Control section above for
powering on the rail.
3. Unit cleaning may be performed at this time if the frost has melted off the surface.
4. Once defrosted, the rail drain may be opened to remove any water that has
resulted from the defrosting procedure.
WARNING: IT IS RECOMMENDED TO ONLY MAKE CHANGES OF 2 DEGREE INCREMENTS
AT A TIME. ALLOW FOR THE UNIT TO OPERATE 24 HOURS BETWEEN
ADJUSTMENTS. IF THE 2 DEGREE ADJUSTMENT IS NOT ENOUGH ANOTHER
ADJUSTMENT CAN BE MADE. IF THE SETTINGS NEED TO GO ABOVE OR
BELOW THIS POINT THERE MAY BE OTHER CONTRIBUTING FACTORS AS
TO THE CAUSE OF THE TEMPERATURE VARIANCES, PLEASE CONTACT THE
FACTORY AT 1-800-621-8560.
AMBIENT CONDITIONS
Unit is designed for normal operating temperatures between 70° F (21°C) - 86°F
(32°C). Operating outside of those temperatures may cause premature product
wear or failure.
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.
