The remaining run time of the decontamination routine designates the period between the start or
the current routine time state and the cooling down to the preset temperature nominal value
(± 2° C).
Heating phase: Remaining run time approx. 25 hours. A The work space is heated to a
temperature of 90° C while an elevated relative humidity is created. The current decontamination
temperature is shown at the temperature display.
Decontamination phase: Remaining run time approx. 23 hours. After the decontamination
atmosphere has been created, the decontamination phase with a run time of 9 hours is started.
If the door is opened during this time, the decontamination routine is restarted automatically as
soon as the door has been closed.
Cool-down phase: Remaining run time approx. 14 hours. The device cools down until the
originally set temperature nominal value is reached.
Postheating phase: Remaining run time approx. 3 hours. During the postheating phase,
condensate within the device is eliminated as far as possible; remaining condensate accumulates
at the bottom of the work space.
Activating the 90 °C decontamination routine
Before running the decontamination routine, fill the water tray with 300 ml of water.
1. Turn the device on:
Press power switch.
All indicators on the control panel illuminate. The software version is shown at the
temperature display and at the CO
2
display.
2. Ventilate work space:
Open both doors until the acoustic alarm sounds after 30 seconds.
The current actual values flash at the displays, the door LED illuminates, the acoustic
alarm sounds after 30 seconds.
3. Start the routine:
Keep the key depressed for 5 seconds.
The 90 °C LED flashes.
Close the device doors:
The actual value is shown at the temperature display. The remaining run time is shown at
