CHECK FOR SHIPPING DAMAGE

Prior to leaving the factory, each cabinet is thoroughly inspected and performance tested up to 12 hours
to assure proper operating temperatures.

Check the crate thoroughly for signs of shipping damage.

If signs of shipping damage are present:

If the damage is severe and obvious, refuse the shipment. The carrier will return the cabinet to the
factory. Call the factory immediately, noting that the shipment was refused and we’ll ship a replacement
cabinet and handle the freight claim.

If no obvious crate damage is present, within two hours of receiving the cabinet from the carrier, remove
the front and side panels to inspect for concealed damage.

1. If concealed damage is found, call the carrier immediately, save all crating materials, and file the
necessary freight claim with the carrier.

2. If no concealed damage is present, reassemble the crate to protect the cabinet for final location
delivery.

WHERE TO LOCATE THE CABINET

• Place the cabinet on a surface strong enough to support the combined weight of the cabinet and the

product load and solid enough to prevent vibration. Guideline: estimate 35 pounds per cubic foot of
storage space.

• Locate the cabinet on a level surface. Minor unevenness can be compensated for by the adjustable

legs or shimming the base or casters.

• Place the cabinet in areas where the ambient room temperatures are between 50

Excessive heat will affect performance and may cause condensation.

o

F and 90oF.

• Locate the cabinet in well-ventilated areas. The cabinet should be protected from heat sources and

direct sun’s rays. If the cabinet is in front of a window, provide an awning or shade to shield the cabinet
from direct sunlight.

• If the condensing unit is located in the bottom of the cabinet, leave an air space of at least 3” in back
of the cabinet for venting the hot air from the unit compartments.

• If the condensing unit is located on the top of the cabinet, it is not necessary to leave space behind
the cabinet. However, 12” of clearance is required from the top of the cabinet to the ceiling.

• Measure all doorways and passages before moving the cabinet to its final location. To pass through
low door openings, first remove the shelves shipped inside the cabinet and lay one- and two-section
upright cases on end.

CAUTION - Lay the cabinet on pads or thick blankets to avoid damage to the cabinet finish. After the
cabinet is set upright, check for oil leaks in the compressor compartment. If you find oil leaks, call a
qualified service person before operating the unit. If no oil leaks are found, wait 1/2 hour before operating
the unit.

REMOVE THE CRATE AND SKID

Remove the crate carefully to prevent damage to the exterior surfaces of the cabinet. The cabinet is
bolted to a wooden skid with four hex-head bolts. After the skid is removed, always use a dolly to move
the cabinet to prevent damage to the cabinet bottom or the floor.

REMOVE THE DOOR AND HINGES

On upright cases, if the doorway or passage way is too narrow, the doors and hinges can be removed.
Open the door 45 degrees and lift the door up and off the hinge pin. Use a phillips head screwdriver to
remove the hinges. When re-assembling the door and hinges, tighten the hinge screws slightly and
rehang the door. Check to be sure the door is properly aligned. Use a block of wood and a hammer to tap

WARNING - The condensate disposal system is designed to dispose of the water from the

evaporator only under normal operating conditions. When cases are used with ice or when
additional water is generated by the case through abnormal usage or ambient conditions, a floor
drain or similar arrangement might be required.

Top mounted units

Depending on the model ordered, an electric condensate evaporator pan is available to dispose of
condensate water. The electric evaporator pan plugs into a 115 V 15 AMP line which should be a
separate line from the cabinet power supply.
