Airflow Auto Adjust (first installation only)

When first setting the airflow on your new extraction unit
the iQ will detect if the desired airflow is achievable with the
installation that has been connected to the extraction unit.
If the installation is causing too much restriction for the
desired airflow to be reached, the Auto Adjust feature will
be activated. The procedure events are listed below.
1) The 3 buttons will begin flashing Red along with the
airflow setting on the LCD screen.
2) The airflow setting on the screen will drop to display the
highest airflow that can be achieve.
3) The airflow will stabilise and the buttons will turn green to
show the airflow has set.
