minute after connection of the power supply, because there is an
automatic delay device in the circuit. Temperature and alarm settings,
however, can be adjusted immediately.
3.2.3 Alarm
Activation
The equipment is delivered with the battery deactivated. The Power Fail
alarm is activated by the battery rocker switch within the lockable panel. On
upright models, the panel is located at the bottom right-hand corner. On chest
models, the panel is located on front right of the unit, near the display. The
switch is labelled
I
(
ON
) and
O
(
OFF
).
(See Figures 1, 2 & 3.)
To activate the alarm, put the battery switch in the
I
position.
After activating the alarm, test its operation by pressing the
ALARM
TEST/MUTE
key on the display. The audible alarm should sound. The
ALARM TEST/MUTE
key also tests the LED lamps. All of the LEDs should
light up together when the button is pressed.
#
NOTE:
When the equipment is first switched on, it will take approximately six
hours to reach a temperature of -86°C. The alarm will sound every 30
minutes until the temperature setpoint is reached. Use the
ALARM
TEST/MUTE
key to mute the alarm during this initial pull-down period.
If the freezer is turned off during the initial pull-down period, the alarm
will activate 30 minutes after you switch it back on again.
The factory-set temperature is –80º C.
