Chromatography Refrigerators

The chromatography refrigerator is equipped with a safety circuit. In the event the safety circuit is tripped (the safety sensor senses a flammable gas), the power to the internal outlet will be discontinued and the user will need to manually reset the safety circuit assembly using the reset switch at the right side of header panel before 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 power is available at the outlet, the red LED will turn off and the green LED will illuminate.
If the circuit trips from RED back to GREEN repeatedly or never turns GREEN, please contact Customer Service.
Flammable materials should not be stored in the refrigerator.
Lights
The GFCI outlet assembly is located inside the unit back in the center.
Switches
The Chromatography refrigerators has a reset switch on the right side of the header panel, above 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 on the right side top front corner next to the remote alarm contacts.

Wiring

The wiring diagram for the units is shown in Figure 2.
CAUTION: Connect the equipment to the
correct power source. Incorrect voltage can result in severe damage to the equipment.
CAUTION: For personal safety and trouble-free operation, this unit must be properly grounded while in use. Failure to ground the equipment may cause personal injury or damage to the equipment.

Installation Instructions

WARNING: Do not to move this unit while loaded
The Sliding doors can be opened completely towards left or right. If the self-closing door does not work properly, make sure the unit is leveled properly
Door Seal
CAUTION: Door seal integrity is critical for unit performance. A loose fitting gasket allows moist air to be drawn into the cabinet, resulting in quicker frost buildup on the cabinet walls, longer running time, poor temperature maintenance and increased operation cost.

Remote Alarm

All units have factory-installed remote alarm contacts that can be used for remote alarm systems. The maximum distance between a unit and a remote alarm depends on the wire gauge used. Refer to Ta bl e 4 below:
The Remote alarm contacts are located on the right side of the header panel. The three terminals are: COMMON, OPEN ON FAIL (Normally Closed) and CLOSE ON FAIL (Normally Open).
