Obstruction in the piping
system
Troubleshooting
CORRECTIVE ACTION
Remove the screw from
the air intake connector,
to free the central vacuum
unit from the piping
system. 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.
