TROUBLESHOOTING GUIDE
PROBLEMS POSSIBLE CAUSES POSSIBLE REMEDY
1. Loss or
decrease
of suction
occurs.
• Debris pail or disposable
bag is completely full.
• Debris pail gasket
damaged or missing.
• Obstruction in the hose.
A blockage in the hose
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
original inlet.
• Obstruction in the tubing
system inside the walls.
• Sealed HEPA permanent
filter or disposable bag torn.
• Wall inlet cover not
properly sealed.
• Exhaust tubing or vent
clogged.
• Change the disposable bag or empty
debris pail as described on page 5.
• 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 permanent filter (or disposable bag).
• Check all wall inlet covers to be sure they
are closed and sealed tightly.
• Inspect and remove any blockages.
