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 manufacture is not
responsible for freight loss or damages.
INSTALLATION
The unit has been secured to the shipping base with four bolts. Remove these bolts and separate
the unit from the shipping base. Locate the casters or legs found inside the unit. Attach the
casters or legs to the unit base by screwing them into the threaded fittings that were used to
secure the shipping base. Use the wrench provided to tighten the casters to the unit. The casters
with the brakes should be installed on the front of the unit. For proper drainage of condensate,
the unit should be level when placed in its permanent location. Leveling shims are in cluded in
the accessories package in the cabinet. Loosen the casters and insert shims between caster and
bottom of the unit. Retighten the caster.
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 at the bottom 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.

OPERATION
Once the unit is connected to the proper power supply, the display panel will be lit for two (2)
seconds followed by a beep, and then the cabinet temperature will be displayed and the
compressor will start to run. The compressor is running whenever ‘comp’ is lit on the display. If
the cabinet temperature is higher than 68˚F (refrigerator) or 14˚F (freezers) the display will read
<Hi> and lower than14˚F (refrigerator) or -50˚F (freezer) the display will read <Lo>. If the unit
does not start immediately, check the power switch located on the bottom of the top grill. If the
cabinet temperature is below 14˚F (freezer) or 50˚F (refrigerator) when the unit is plugged in
there will be a three minute delay before the compressor will start.
The interior light will come on when a door is opened.
Whenever a door is opened the door open light on the display will be lit and the evaporator fans
will stop. The fans will start three seconds after the door is closed. If a door is open for more
than 30 seconds, the door open alarm will beep two times. If a door is open more than 60
seconds, the alarm beeps five times and if open more than five minutes the alarm will beep
continuously.
The electronic control has an alarm function to remind the operator to periodically clean the
condenser coil. The condenser coil will collect dust and debris during normal operation. If left
unclean, this will lead to poor performance, high energy consumption and possible compressor
failure. Warranties do not cover failures related to condenser cleaning. At 6 month intervals the
display will blink “CL” and the buzzer will sound to remind the operator to clean the condenser
coil. After one hour the buzzer will stop but the display will continue to blink “CL”. Refer to
the ‘MAINTENANCE’ section of this manual to learn how to clean the condenser coil. The
electronic control can be reset to normal operation by pressing the ‘Mode’ and ‘Verify’ buttons
at the same time for five seconds. Depending on conditions, the condenser coil may require
more frequent cleaning.
MAINTENANCE
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 and 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.
