Stabilization:
CAUTION: The HemaCool™ must be started and allowed to operate for a 24-hour

unit’s batteries are fully charged. Battery charge level is shown on the display (see
Display and Alarm Functions, below). Never begin a portable mission if the battery
voltage is below 14.2 volts.

The temperature within the
HemaCool™
will reach satisfactory levels for storing the
payload well before the twenty-four hour stabilizing period ends. However, the unit will
not achieve peak energy efficiency until 24 hours of continuous operation has been
completed.
During stabilization, the unit’s power demand will be above average. Therefore, it is
recommended that charging be done with an external power source during the first 24
hours, and any time batteries require charging.
Once this stabilization time is completed, the unit may be disconnected from the cabled
power source. It is then portable and under internal battery operation. If the unit is
