8. Startup
8.1 Initial Startup
To start up the refrigerator, complete the following steps:
1. Verify that the sensor probe(s) have been installed in the bottle(s) as described in
Section 7.7
.
2. Connect the AC mains power cord to the mains power inlet connector.
3. Ensure the double pole circuit breaker switch located next to the power inlet is in “ON” position (i.e. “
I
” position).
4. Insert the key in the switch and turn to the
Power On
position. The display will show the actual
cabinet temperature and the compressor and evaporator should start within approximately 10 minutes.
5. 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.
6. If you desire to enable the alarms, turn the three position key switch one turn further clockwise to the
Alarm On
position. To avoid nuisance alarms, wait until the unit has pulled down to the desired operating temperature
(5°C
default).
7. If you have a remote alarm, hook it up at this point (refer to
Section 7.9
).
8. If desired, lock the cabinet door using the 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.
8.1.1 Additional Chromatography Refrigerator Startup
1. Connect the AC chromatography power cord to the chromatography power inlet connector.
2. Toggle the Chromatography power inlet and Chromatography manual reset switches to ON. If the internal outlet is
GFCI protected, it may need to be reset.
Note
The Chromatography refrigerator is shipped with the Manual reset switch at the back of the unit (refer
Section 7.3.4) as ON. The Manual reset switch should always be in ON position.
Upon startup, the red LED on the chromatography safety circuit turns ON. After a power delay of approximately 4
minutes, the red LED on the chromatography safety circuit turns OFF and the green LED on the chromo safety circuit
turns
ON.
Note
When the red LED is ON, the outlet will not be powered. The LEDs indicate the status of the safety
circuit
only.
Note
Operating equipment inside the refrigerator may shift the temperature profile in the unit. Monitor the
refrigerator as needed for any such shift.
