INSTALLATION AND OPERATION INSTRUCTIONS

FOR

UNDERCOUNTER REFRIGERATORS/FREEZERS

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.
1 shelf can support up to 132 lbs(60kg).

The refrigeration system located in the rear 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 top, right corner inside the cabinet. Adjust the
temperature to fit your needs.

Install casters per the following diagram.

Note: The casters with brakes should be installed to the front of the cabinet.

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.

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 rear 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 fans in the back. Blocking the air flow
may decrease performance.
