1. What to do when the vacuum cleaner has experiences a loss of suction.
When the appliance has been used for some time and you notice that the suction power is weaker
than before or that there is no suction at all, take the following steps:
a) First check the dust container and empty it. After emptying the container, if suction remains
weak, clean the filter as well. The machine should work satisfactorily after carrying out these
steps.
b) If some inlet valves work and whilst others don't, this could be explained by blockages in
the ducting.
c) If there is no suction at any of the inlet valves unplug the air inlet connection from the
central vacuum unit.

obstruction close to the central vacuum unit. Check all the inlets to find the point of the
leak. If you cannot locate this contact your service engineer.

the motor. Contact your service engineer.

the obstruction towards the central vacuum unit.
c) Unplug the central vacuum unit and unfasten the dust container and remove it. Then
