7. Startup
Initial Startup
To start up the unit, complete the following steps:
1. Connect the AC main power cord. The evaporator fans start when the power cord is plugged in.
2. Insert the silver colored key in the switch and turn to the Power On position.
3. Allow the unit to reach operating temperature before loading it with any product. To stabilize the
temperature profile, a 24-hour waiting period is recommended.
4. If you desire to enable the power failure alarm, turn the three position key switch one turn further
clockwise to the All Alarm On position.
5. If you have a remote alarm, connect it at this point (refer to section Remote Alarm).
6. If desired, lock the cabinet door using the silver colored key. Place duplicate key copies in a safe place.
All controls should now be fully operational, the alarm active (if enabled), and all visual indicators active.
Chromatography Refrigerators
1. Connect the AC main power cord.
2. Connect the GFCI AC power cord.
3. Make sure the reset switch is in ON position.
4. Insert the silver colored key in the switch and turn to the Power On position. The display will show the
actual cabinet temperature.
Note:
The Chromatography refrigerator is shipped with the manual reset switch on the right side of the
header panel above the remote alarm contacts (refer to section Switches) as ON. The Manual reset switch
should always be in ON position.
5. The red LED on the chromatography safety circuit turns ON.
6. After a power delay of 4 minutes the red LED on the chromatography safety circuit turns Off and the green
LED on the chromatography safety circuit turns ON.
Note:
During initial power-up, the GFCI outlet will not be powered until after an approximate 4 minute
delay. Operating equipment inside the refrigerator may shift the temperature profile in the unit. Monitor the
refrigerator as needed for any such shift.
Product Loading and Unloading Guidelines
When loading your unit, take care to observe the following guidelines:
• Distribute the load as evenly as possible. Temperature uniformity depends on air circulation, which could
be impeded if the internal storage components are overfilled, particularly at the top of the cabinet.
• For critical applications, be sure that the alarm systems are working and active before you load any
product.
• Ensure clearance between the top of the cargo and the bottom of the internal storage components. Lack
of clearance may affect unit performance or impede operation of the storage component.
