Operation
Turning extraction unit on
The ON / OFF switch must be switched to the “On” position
(Refer to section 1 for switch location) by depressing the ‘I’
side of the switch.
Setting the desired airflow
The unit features manual flow control. This enables the user
to set the required airflow rate. Over time as the filters
begin to block the user should manually increase the motor
speed to ensure the correct flow is maintained to
compensate for any loss in performance caused by the
added restriction of the partially blocked filters.
The extractor and all pipe work must be fully
installed and connected before the airflow is set.
To set the airflow
Press the Up arrow button to increase airflow and press the
down arrow button to decrease airflow. The level of airflow
is indicated by the vertical row of six blue LEDs to the right
of the mains isolation switch. As the airflow increases, more
blue LEDs light up and the opposite for decreasing the
airflow.
