Thermo Scientific TSX 5.5 cu.ft Undercounter Refrigerator Installation and Operation 11
6 Operation
6.1 LED Indicator When you turn on your refrigerator, verify that the LED indicator is working.
The LED indicator appears on the front control panel next to the upper corner
of the display. The LED indicator illuminates green when the unit is on and
running. It illuminates red if there is a data log concern such as:
•LowBattery
• Full Memory
• Data Logging Error
A power outage would result in a flashing red or green light every 15 seconds.
Flashing green indicates continuous data logging. Flashing red indicates a data
logging error. See the troubleshooting guide for ways to resolve the issue.
6.2 Checking the Glycol
Sample Bottle
The glycol sample bottle is pre-installed inside your unit. The sample bottle
allows you to monitor the internal temperature of items being stored in the
refrigerator.
Verify the following:
1. The cord for the sample bottle is fully plugged into the back wall of the
interior of your unit.
2. The sample bottle is securely mounted in the clip provided.
3. The level of the propylene glycol in the bottle is full.
In the event that the bottle has broken during shipping, contact our service
department for a replacement bottle.

Operation
12 Installation and Operation Thermo Scientific TSX 5.5 cu.ft Undercounter Refrigerator
6.3 Preprogrammed
Settings
Settings can be customized via the Settings and Alerts menus.
Temperature Display & Alarm – The display is preset to read the glycol sensor
but can be changed to read the air sensor. Temperatures are detected and
displayed in Celsius units to one tenth of a degree. For example, 4.0°C. Upper
and lower alarm thresholds are driven by door the sensor selected for the display.
• Set Point Temperature – The unit preset/default is set at 5.0°C (39.2°F)
• Upper Threshold Alarm – The unit preset/default is set at 8.0°C (46.4°F)
• Lower Threshold Alarm – The unit preset/default is set at 2.0°C (35.6°F)
6.4 Preset alarms/alerts The following alarms/alerts are factory preset:
6.5 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. Reaching Glycol set point temperature will take longer.
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

Operation
Thermo Scientific TSX 5.5 cu.ft Undercounter Refrigerator Installation and Operation 13
3°C. If the set point temperature is 4°C, then the alarms are enabled when the
unit reaches 7°C.
6.6 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. There are
three temperature monitors inside the refrigerator, the glycol sensor and two air
sensors. When you load the refrigerator, always remember to provide some
clearance around the air and glycol sensors and make sure the glycol sensor
remains properly connected.
When loading products previously stored at room temperature, monitor the
temperature display to prevent a compromise. We suggest you load room
temperature samples in small increments to help maintain a stable temperature.
Don’t load product until the preprogrammed set point is reached.
Always provide adequate clearance around both the air and glycol sensors.
6.7 Tips for Managing
Door Openings
When a refrigerator door is opened, warmer ambient air enters and causes the
interior temperature to fluctuate. To 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 TSX compact refrigerators have a visible and an audible open door alarm
that sounds when a door has been open for more than 1 minute.
6.8 Automatic Defrost
Cycles
The TSX refrigerator will run a pre-programmed automatic defrost cycle every
24 hours. During the defrost cycle you will likely hear the fan turning off and on.
In addition to the automatic defrost cycles, you can initiate a manual defrost
cycle through the Settings menu.
