The refrigeration system located at the bottom of the unit requires free air access for
proper operation. Allow a minimum of 180mm (7 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.
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, 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
℉
(
+15
℃
)
(refrigerator) or +14
℉
(-5
℃
)
(freezer), the display will read <Hi>. If the cabinet temperature is lower than +14
℉
(
-2
℃
)
(refrigerator) or -50
℉
(
-40
℃
)
(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
℉
(
-10
℃
)
(freezer) or +50
℉
(
+10
℃
)
(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. The top doors activate the light on
half-door cabinets only. Note: the light is always on in the Glass Door models. If you want
to turn off the light, use the light switch on the top grill.
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 three 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. On half-door cabinets only, the top doors
activate this feature.
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/Set’ and ‘Verify’ buttons at the same time for five
seconds. Depending on conditions, the condenser coil may require more frequent
cleaning.
When a door is closed on a cabinet that is running, an internal vacuum is created as the
internal air is cooled and the door can be difficult to open for a while. These units
incorporate a pressure relief valve that equalizes the vacuum to allow the door to be
opened sooner.
