SHALLOW BACK BAR REFRIGERATION
Installation, Operation and Maintenance Instructions
INSPECTION
When the equipment is received, all items should be carefully checked against the Bill
of Lading to ensure all crates and cartons have been received. Do not sign the freight
bill clear until the freight has been properly inspected for damage. All units should be
inspected for damage including concealed damage by uncrating immediately. If any
damage is found, it should be reported to the carrier at once, noted on the Bill of Lading
and a claim should be filed with the carrier. This equipment has been inspected and
tested in the manufacturing facility and has been crated in accordance with
transportation rules and guidelines. The manufacturer is not res ponsible for freight loss
or damages.
INSTALLATION
After removing the unit from the packaging, clean the interior and exterior surfaces of
the unit with soap and water and a rinse with clean water. Do not use chlorinated
cleaners on the surfaces as they can cause corrosion.
This unit is designed for indoor use only. Be sure to locate the unit where the floor can
support the weight of the unit and product installed inside of it. The refrigeration system
located at the bott om left of the unit requires free air access for proper operation. Allow
a minimum of seven (7) inches between the back of the cabinet and the wall. Do not
locate the unit next to heat generating equipment or in direct sunlight.
Confirm that the proposed electrical outlet has the correct voltage, frequency and
current carrying capacity for the requirements of the unit. This information is noted on
the data plate on the inside left wall of the unit. The unit should be isolated on a circuit.
Do not use an extension cord to get power to the unit. Improper electrical installations
will void the compressor warranty. To prevent shock and fire, be sure the unit is properly
grounded.
Local health codes may require that the unit be sealed to the floor with an NSF
approved silicone sealant if it is not on legs or casters. After the unit is set in its desired
location, simply apply a bead of sealant around the base of the unit and smooth it out.
The shelves and shelf support clips are shipped inside the cabinet. Install the shelf
support clips on the pilasters mounted on the inside walls of the cabinet and set the
shelves on the supports. The shelves are adjustable in ½” increments to suit your
needs.

If the doors have come out of alignment during shipping, they will need to be adjusted.
This can be accomplished by opening the door(s) and loosening the screws that hold
both the top and bottom hinges to the cabinet. After adjusting the door so it is aligned
correctly, tighten the screws to securely hold the hinges and door(s) in place.
OPERATION AND MAINTENANCE
This cooler is designed to maintain your product temperature within the most desirable
range of +34°F to +38°F. You can expect this temperature with the proper temperature
control setting and in a normal environment. It is important to remember that when the
product is delivered, it must be placed inside the cooler as soon as possible to avoid
excessive warm up. If this happens, it may take many hours for the temperature to be
reduced to the desirable range.
The temperature controller is located on the left end of the unit cooler. Turn the control
clockwise for cooler temperatures and counterclockwise for warmer temperatures.
Allow the unit several hours to respond to temperature control adjustments.
There are interior lights located above the door. The light has an on/off switch on the
unit cooler.
When loading the cabinet with product, do not block the air flow path. Blocking the air
flow may decrease performance. Maintain clearance between the contents and air duct
for best performance.
This equipment is intended for the storage and display of pre-packaged food product
only.
Cleaning
Beginning with the initial installation, the interior surfaces of the cabinet should be
periodically cleaned with a solution of warm water and baking soda. This solution will
remove any odors from spillage that has occurred. The exterior of the cabinet should
also be cleaned frequently with a commercial stainless steel cleaner, glass cleaner or
mild soap solution. Do not use chlorinated cleaner s on any surfaces.
The shelving can be cleaned in a sink with a mild soap solution and a soft bristled
brush.
Condenser Coil
Prior to cleaning the condenser coil disconnect the unit from power. Periodic cleaning
of the condenser coil will aid the heat transfer of the refrigeration system and increase
its efficiency. To accomplish this, remove the lower front grill from the cabinet. The
condenser coil is located behind the grill. Use a soft bristled brush to remove any dirt
particles that are on the fins of the condenser coil. Use a vacuum cleaner or
compressed air to remove the loosened particles. Replace the front grill and reconnect
the unit to power. Failure to clean the condenser coil can lead to performance loss and
compressor failure.
