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.
General Purpose and Chromatography Refrigerators
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.
