CAUTION: Selecting the wrong set point for your materials can damage or destroy
them.
It is the end user’s responsibility to choose the control set point that matches the
temperature requirements of the payload. If in doubt, contact the manufacturer of the
materials to be stored for the temperature requirements so that the correct control set
point is selected.
The set point selected is indicated on the LCD readout -- COOL or
FREEZE -- by the letters “c” or “f”, respectively, at the right end of the upper line
of the display (
see
HemaCool™
Display and Alarm Functions, below).

up
for
4.0°C
(39°F) control
setting, and

(-7°F)
operation
(Fig. 8
, number

3.
Attach the external source
of power selected for the unit’s initial 24-hour cool-
down and stabilization period (connectors at
Fig. 8,
numbers
2
and
3)
. Plug the
power source into the control and power panel (
Fig. 8
) on the electronics end of
the unit (right side
Fig. 1
).
CAUTION:
Only AC power (and optional solar power) inputs charge the batteries.
Though engaged to the same connector as solar power, 12 VDC and 24 VDC
auxiliary power is applied through an isolated pin and does not
charge the batteries
.
It can, however, be used to assume the load of the 24-hour stabilizing period.
4.
Press the ON/OFF button
(
Fig. 8
number
4
). When operated from AC power,
the unit’s indicator lamps above and below the temperature selector (
Fig. 8
number
1)
will illuminate to show the unit is operating and at which temperature
setting. If you are operating on battery power, only the display panel lights will
come on. This is how you can be sure your AC power is connected and switched
on. Be sure the correct setting for your payload is indicated. The unit will now
run, and the bottom line of the display (
Fig. 9
) will read “STABILIZING 24hr”.
