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.
