8. Put the speed control in the box fitting
and fasten it with the screws.
To ensure normal operation as intended the
speed control must be regulated for minimal
rotation speed:
1. Turn the dial anticlockwise while the
control is in switched on mode (without
the dial clicking and switching off).
2. Connect the power.
3. Use a Phillips screwdriver with
an insulated handle to turn the
potentiometer (8) until a minimal
rotation speed is achieved.
4. Turn the dial anticlockwise to the off
position (so that a clicking noise is heard).
Wait for the rotation of the fan to stop.
5. Turn the dial to minimal fan speed and
it is now adjusted for a stable minimal
rotation speed.
6. Fit the frame and tighten the nut.
7. Fit the dial.
NOTE:
The speed control must not be used if the minimal rotation speed is not set correctly. The fan can
be damaged if the minimal rotation speed is not correct.
