OSSIBLE CAUSES
can be determined by inserting the hose into
any wall inlet and, while power unit is running,
check each additional inlet for normal suction
by holding the palm of your hand over the
open inlet. If normal suction is felt at all other
inlets, insert the hose into a second inlet. If the
blockage still exists it is located in the hose.
However, if the blockage does not occur when
the hose is changed, the blockage is probably
located in the tubing system leading to the

OSSIBLE REMEDY
• Empty debris pail or change the disposable bag
as described in user guide on page 4.
• Replace the debris pail gasket.
• Disconnect the hose from the wall inlet and
insert a blunt instrument into the hose —
slightly smaller in diameter — such as a flexible
garden hose. Push the garden hose through the
cleaning system hose until the obstruction has
been cleared.
• Insert hose end into any inlet to make power unit
running, then place the palm of your hand over
the opposite end of the hose. When you can feel
the suction increase, hold your hand over the
hose end for a few seconds and then quickly
remove your hand. This procedure repeated
several times should clear the obstruction. If the
blockage is not cleared, contact your nearest
Service Center.
• Clean the interior or the unit and install a new
sealed HEPA permanent filter (or disposable
bag); see user guide on pages 4 and 5.
• Check all wall inlet covers to be sure they are
closed and sealed tightly.
• Inspect and remove any blockages.
• Replace defective wall inlet.
• Push on
