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.

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.
