Installation, Operation and Maintenance Instructions
__________________________________________
INSPECTION
When the equipment is received, all items should be carefully checked against the Bill of
Lading to insure 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 responsible for freight loss
or damages.
INSTALLATION
The exterior of the cabinet and doors have been protected by a plastic covering. Peel
this protective covering before installation. After removing the covering, 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.
If the door(s) 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
correct, tighten the screws to securely hold the hinges and door(s) in place.
The shelves and self clips are packaged inside the unit. Install the shelf clips on the
pilasters inside the unit and set the shelves on the clips. The shelves are adjustable in
½” increments.
The refrigeration system located on the right side of the unit requires free air access for
proper operation. Allow a minimum of seven 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.
The temperature controller is located at the right side of the cabinet interior. The default
temperature is set at “Normal”. Adjust the temperature to fit your needs.

Install casters per the following diagram.
Note: Casters and bolts can be found packaged inside the cabinet. Install casters with
brakes to the front of the prep table. The cabinet bottom has pre-punched holes for
caster mounting. Install caster bolts tight to prevent future damage to cabinet base from
loose casters.
MAINTENANCE
General 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 cleaners on the stainless steel surfaces.
Note: do not use stainless steel cleaners or other solvent-based chemicals on the plastic
parts (door handle or trim strips) as they can cause failure. Use mild soap and warm
water on plastic parts.
The door gaskets should be cleaned in place with a mild soap solution to extend their
life.
The shelving can be cleaned in a sink with a mild soap solution and a soft bristled brush.
Condenser Coil Cleaning
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 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 grill and reconnect the unit to power.
Failure to clean the condenser coil can lead to performance loss and compressor failure.
Stocking
When loading the cabinet with contents, do not block the fan on the right side. Blocking
the air flow may decrease performance.

TROUBLESHOOTING
Problem Remedy
Compressor will
not start
·Check the power cord and make sure it is plugged in.
·Check the temperature controller. If it is in the “OFF”
position, turn it clockwise to set a desired temperature.
Poor performance
·Move the unit from direct sunlight.
·Move the unit away from heating devices.
·Install the unit in a well ventilated place, with at least 7
inches of clearance on all sides.
·Clean the condenser if heavy dust is collected.
·Clear contents from blocking the air duct.
·Check the temperature controller for incorrect setting.
·Check the refrigerant level, it may need to be charged.
·Check the door and be sure it is completely closed.
Unit noisy
·Check fan blades to see if they are contacting anything.
·Maintain 7 inches of clearance from the wall.
·Check for loose part or mounting.
·Keep the tubing free from any contact to avoid rattle.
Condensation on
cabinet exterior
and/or floor
·Reduce humidity where the unit is installed.
·Repair or replace the gasket on the door.
