1. Loosen the screw in the bottom of the grille and remove the front grille.
2. Carefully pull the inner cap from the centre of the fan away from the chassis.
3. Adjust the settings as outlined below.
Trickle speed selection (6l/s or 9l/s) – (Fig. 7)
In normal running mode the fan can extract at either 6l/s (22m
rate. The fan will boost to 15l/s (54m
• Factory set at 6l/s (22m
• Remove jumper connector (JP1) if 9l/s (32m
required.
Airflow detection system – enable/disable (Fig. 8)
The airflow detection system will detect the installation duct resistance and also react to
external wind conditions to ensure the fan maintains a constant extraction rate. This can
cause the fan to ramp up and down and in most applications will not be required. To turn
this feature on, complete the following:
• Push switch (SW1) into the on position to turn on constant flow mode.
• Push switch (SW1) into the off position to turn off constant flow mode.
(Factory set)
IMPORTANT – On first power up, the fan will run through its initialisation routine. This
will involve the fan running on maximum speed for 10-20 seconds. After which the fan
will run as normal and will not need to be initialised/calibrated again. The fan will
remember its settings if there is a power cut.
