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.
