Decrease in
suction strength
Obstruction in the
piping system
Loosen the clamp collars
around the air intake connec-
tor, to free the central vacuum
unit from the piping system
(see figure 3 on page 5). 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 suc-
tion 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.
