In order to ensure that normal operation works as intended, it is essential that the speed regulator
is set to minimal rotation speed:
– Turn the control knob anticlockwise whilst the regulator is switched on (the control knob
does not click and shut off)�
– Connect the power�
– Use a Philips screwdriver with an insulated handle to turn the potentiometer (8) until
minimal rotational speed is achieved�
– Turn the control knob anticlockwise to the off position (a click is heard)� Wait until
the fan stops rotating�
– Turn the control knob to minimum fan speed - it is now adjusted to deliver a stable
minimum rotation speed�
– Fit the frame and cover and tighten the nut�
– Fit the control knob�
NoTE:
The speed regulator must not be used if minimum rotation speed is not correctly set as this may cause
damage to the fan�
