than 3 minutes.
If CO₂ deviation is more than ±1% from set point for about 3 minutes, alarm starts ringing. So, CO₂
alarm tolerance delay is about 3 minutes.
Door Open
The outer door is open for longer than one minute.
*When pressing the alarm mute button on the control panel will stop the alarm from activating. If
the alarm was stopped by mute button, the alarm will be re-activated after 3 minutes.
6.6. Water tray
An additional water tray at the bottom of the chamber enables a high, uniform relative humidity
while its special double-dish or dish tray design that creates cold point preventing condensation in
other parts of the chamber. Perforated shelves are provided as standard to facilitate recovery of RH
conditions in the chamber.
6.7. Hot Air Sterilization
（
Only for Sterilization model
）
When CO
2
incubators are used in contamination hazardous areas, hot air sterilization can be used as
an additional means of cleaning the inside of the chamber. Hot Air Decontamination uses 6 side direct
heating up to 125°C. This makes chamber decontaminated destroying bacteria and germ. High
Temperature (125°C) is maintained in chamber for more than 2 hours. After 8 hours sterilization
program (including 2-3hours of warm up time depending on), the temperature in chamber decreases
and recovers to 37°C or last programmed temperature. CO
2
gas is also re-set at 5% or last
programmed point automatically. Hence, immediate cell culture is available after approximately 10
hours sterilization cycle.
Caution for Hot Air Sterilization USE.
Before operating Hot Air Sterilization, ensure the following:
1.
Removing CO
2
Sensor are not required as both sensors are located outside the chamber.
