Operating the ozonizer
As soon as the power supply is connected, the
ozonizer starts up automatically.
During startup, the display
(2)
briefly shows
the Sander logo, and then changes to the main
control interface:
The upper bar graph (»Air«) indicates the
amount of airflow through the ozonizer in litres
per hour.
While ozone production is off, the display
shows the label »OZON OFF«.
Use the center button (
I/O
) to turn ozone
production on or off.
The lower bar graph (»O3«) indicates the ozone
output as a percentage.
Use the
–
and
+
buttons to reduce or increase
ozone output stepwise from 0 percent (off) to
100 percent (full power).
Both bar graphs consist of two parts: a thick
center bar with two thin bars above and below.
The thin bars indicate the set value, while
the thick bar indicates the actual (current)
measured value.
Using a redox controller
When using a redox controller, ozone
production is turned off automatically once
the target redox potential set on the redox
controller has been reached. When the redox
potential drops below the set value, ozone
production is resumed.
Ozone output throttling with
insufficient airflow
If airflow drops below 250 litres per hour,
the ozonizer will reduce ozone production
proportionally to prevent overheating.
Example: If airflow is 125 litres per hour, and
ozone production is set to 100 %, the ozonizer
will operate with a throttled output of 50 %.
The minimum required airflow is 75 litres per
hour. In the event that airflow drops below
this limit, ozone production is shut down
completely to protect against overheating.
