Stopping a Run
At any time, you can stop a run prematurely by pressing the
STOP button on the front panel of the Controller.
If you subsequently press RUN, the chamber will heat or cool, as
necessary, to reach the start temperature of the program again.
The light flashes and the bleeping sounds when the freezer is at
the start temperature. Pressing STOP again at this point, will
terminate the profile with the chamber left at the normal start
temperature.
Shutting Down the System
It is important to ensure that a program is not running, by
pressing STOP if necessary, before switching off the Kryo1060.
This avoids unnecessary discharging of the backup battery. ( see
Power Failures below )
Remove all specimens from the chamber.
Turn off the liquid nitrogen tap and then press the manual
override cool button at the rear of the Controller to release the
nitrogen pressure.
Switch off the freezer.
Power Failures
An integral backup battery allows the profile to continue to run
for 1 minute following a loss of mains power, although the
solenoid valve and heaters do not operate. If mains power is
restored within this period, the system regains control of the
chamber temperature. If the power is not restored, the profile
terminates.
