OPERATION
MUTING THE AUDIBLE TEMPERATURE ALARM
Audible and visual deviation alarms activate if the incubation chamber
temperature deviates by 1°C above or below the temperature setpoint. The
low deviation alarm has a delay of 15 minutes to prevent the low alarm
from sounding each time the doors are opened, causing a short-lived drop
in temperature.
To mute an audible high or low deviation alarm:
Press and hold either the Up or Down arrow button on the
Temperature Control until the amber Mute LED illuminates and the
audible alarm shuts off.
• The audible alarm will remain muted for the duration of the
current temperature deviation.
• The visual alarm indicator will remain illuminated.
• Any new deviation of ±1°C or greater will reactivate the
audible alarm.
AUTOMATIC DOOR CUTOFFS
Gas, heating, and air circulation pause.
Whenever the outer incubation chamber door is opened, the incubator automatically stops the flow
of CO
2
into the chamber, depowers the heater element, and ceases operation of the internal blower
fan. This limits the amount of CO
2
released into the workspace around the incubator. It also prevents
the heater from attempting to counteract the continuous inflow of cooler air, which would cause a
significant heat spike once the door is closed. Normal CO
2
injections, heating, and fan operation all
resume automatically when the outer door is closed.
