Dirt recipient / Bag is
full
Empty dirt recipient /
change bag (see page 22
to 24).
Dirt recipient is not
properly attached
Check clamps holding
dirt recipient, to make
sure they are tight, and
dirt recipient is aligned.
Open vacuum inlet
Close all vacuum inlets
not in use.
Exhaust line is clogged
Verify that no object is
blocking the exhaust.
Blocked hose
Plug the handle end
of the hose into the
suction inlet, thus
reversing the suction in
the hose. Cover the gap
around the handle, to
ensure suitable suction
strength, and ensure
contact with inlet
contacts to start the
unit. This should clear
the hose.

Obstruction in the
piping system
Remove the screw from
the air intake connector,
to free the central
vacuum unit from the
piping system (see figure
3 on page 8). Start the
unit by plugging the
hose into a vacuum
inlet. By placing your
extended hand over
the air intake opening
on the unit, check the
suction strength on the
unit itself. If suction
strength is normal, the
obstruction is in the
piping system. If suction
strength is diminished
or completely absent,
have the unit checked
by an authorized service
center.
If none of these suggestions restore suction strength,
contact your authorized service center.
