Maintenance
Cleaning the Unit
(Chromatography
Refrigerators)
Use a solution of water and a mild detergent for cleaning.
Lightly spray the interior storage components and wipe them
dry with a soft cloth or spray the cloth first and then wipe
interior surfaces.
Do not spray or pour directly into holes and gaps in the
chromatography safety circuit assembly for cleaning. Use a
wet wipe to clean around sensor box and outlet.
If the sensor led turns red after cleaning, manually reset the
safety circuit assembly using the manual reset switch on the
right side of header panel.
Replacing Sensor
(Chromatography
Refrigerators)
The sensor needs replacement if the temperature goes below
freezing in the cabinet. Use system alarms to ensure the
temperature inside the unit is always above 0°C. If exposed to
freezing conditions the sensor should be replaced.
If the display shows an error and sounds an alarm (in case of
a control, defrost, bottle or ambient probe failure), the sensor
needs to be replaced.
Sensor Maintenance
(Chromatography
Refrigerators)
The sensor should be replaced every five years by a trained
service provider.
