Chromatography Refrigerators
The chromatography refrigerator is equipped with a safety circuit. When the safety circuit is tripped, the
safety sensor senses a ammable gas and the power to the internal outlet will be discontinued. The user will
need to manually reset the safety circuit assembly using the reset switch at the right side of header panel
before the power is restored. To do this, toggle the switch located on the top right side of the header panel
beside the remote alarm contacts. There will be a power delay to the outlet for approximately 4 minutes
where the red LED will be illuminated.
When there is power at the outlet, the red LED will turn o and the green LED illuminates.
If the circuit trips from RED to GREEN repeatedly or never turns GREEN, contact Customer Service.
Flammable materials should not be stored in the refrigerator.
Lights
The GFCI outlet assembly is located inside the unit on the rear wall at the center.
The outlet assembly has two LEDs:
• RED (on the top) - When the red LED is ON, it indicates there is no power to the AC outlet inside the unit.
• GREEN (on the bottom) - When the green LED is ON, it indicates there is power to the AC outlet inside the
unit.
14
Switches
The Chromatography refrigerator has a reset switch on the right side of the header panel above the remote
alarm contacts.
Chromatography Manual Reset: This is used to manually reset the safety circuit in the AC receptacle assembly
after the LED turns RED from GREEN due to a safety trip event which disengages power to outlet inside the
refrigerator. It is present at the top front corner on the right side next to the remote alarm contacts.
