8.1 Initial Startup

Thermo Scientific
To start up the freezer, complete the following steps:
1. Ensure the double pole circuit breaker switch located next to the power
inlet is in "ON" position (i.e. "I" position).
2. Insert the silver colored key in the switch and turn to the Power On
position. The display will show the actual cabinet temperature and the
compressor should start within approximately 10 minutes.
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 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 cooled down to the desired operating
temperature (-20°C default).
5. If you have a remote alarm, hook it up at this point
(refer to Section 7.8).
6. If desired, lock the cabinet door using the gold 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.
CAUTION: Use gloves when handling samples to avoid potential frost
bite.
