Operation
To turn the unit off:
1. Remove all samples from the chamber and store them properly.
2. Remove any accessories from the chamber, and clean and disinfect
them.
3. Clean and disinfect the chamber surfaces, work tray, and drain pan.
4. Turn the unit to standby mode by first closing the window. Then press
the “Fan” button to turn off the blowers.
Caution
For safety reasons, the blowers can be switched off only when the
front window is closed.
s
The safety cabinet should remain connected to the power supply system at
all times to ensure that settings for the individual unit configuration
remain active in the memory. If the power supply is interrupted and later
the power supply connection has been reestablished, the system switches to
the operating mode that had been active last. Additionally, a window with
the message „Mains voltage has been restored“ appears as soon as power
has been restored, prompting the user to confirm by tapping OK. This
message may, for example, be caused by a power outage.
