Risk of electrical shock. If the cord or
plug becomes damaged, replace with a cord and
plug of the same type and rating.

8 | Operation 5.5 cu.ft. Undercounter Refrigerator
Operation
LED Indicator
When you turn on your refrigerator, verify that the LED
indicator is working. The LED indicator appears on the front
control panel above the battery. The LED indicator illuminates
green when the unit is ON and running (Under normal
operation). It illuminates red if there is a concern such as a low
battery or other alarms.
Preprogrammed Settings
Settings can be customized via the Settings and Alerts
menus.
Temperature Display & Alarm – Temperatures are detected
and displayed in Celsius units to one tenth of a degree. For
example, 5.0°C. Upper and lower thresholds are driven by
internal air sensor.
• Set Point Temperature – The unit preset/default is set at
5.0°C (41°F)
• Upper Threshold Alarm – The unit preset/default is set at
10.0°C
(50.0°F)
• Lower Threshold Alarm – The unit preset/default is set at
2.0°C
(35.6°F)
Preset Alarms/Alerts
The following alarms/alerts are factory preset:
Set Point Temperature
When you first turn on the unit, the fan will run and the
refrigerator will work to reach the default set point
temperature. Once set point is reached, the fan speed will
reduce to conserve energy. The unit will reach air temperature
setting rapidly.
When the unit is first plugged in and powered, the
temperature range alarms are not enabled until the unit
reaches its preset temperature range + an offset of 3°C. If the
set point temperature is 5°C, then the alarms are enabled
when the unit reaches 8°C.
Loading Products for the
First Time
After you power on your refrigerator, monitor the temperature
display on the control panel and do not load until the default
set point is reached. When you load the refrigerator, do not
block air flow around the air sensor.
When loading products previously stored at room
temperature, monitor the temperature display to prevent a
compromise. We suggest you to load room temperature
samples in small increments to help and maintain a stable
temperature.
Tips for Managing Door
Openings
When a refrigerator door is opened, warmer ambient air
enters and causes the interior temperature to fluctuate. To
A power outage/backup battery would result in a
flashing light and audible beep every 5 seconds
until battery is exhausted.

5.5 cu.ft. Undercounter Refrigerator Operation | 9
limit this effect, there are a few simple steps you can follow to
reduce the number of times the door is opened as well as the
duration it is left opened:
• List a detailed inventory of the refrigerator’s contents on a
chart posted outside the unit to reduce the time spent
searching for items when the door is opened.
• Use clearly labeled bins to organize and quickly identify
contents.
• Avoid storing beverages or any non-sample items (like
food) in any unit used for sensitive inventory. Not only is
this a health hazard, it also leads to more frequent
opening of the door.
Note: Isotemp undercounter refrigerators have a visible and
an audible open door alarm that sounds when a door has
been open for more than 1 minute.
Automatic Defrost Cycles
The Isotemp refrigerator will run an automatic defrost cycle to
maintain its performance. The period between defrost cycles
will vary depending on the refrigerator use conditions (ranges
from 6 hrs to 96 hrs). During the defrost cycle you may hear
the fan turning off and on.
