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.
