8. TROUBLESHOOTING GUIDE
PROBLEMS POSSIBLE CAUSES POSSIBLE REMEDY
1. Loss or
decrease
of vacuum
occurs.
• The plastic cap is not installed on
the unused inlet.
• Debris pail or disposable bag is
completely full.
• 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.
• Wall inlet cover not properly
sealed.
• Place the included plastic cap on
the unused inlet opening.
• Change disposable bag or empty
debris pail as described on page 4.
NOTE: Clean secondary filter if
necessary.
• 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 with
power unit running, 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.
• Check all wall inlet covers to be sure
they are closed and sealed tightly.
2. Power unit
does not
start or
stops
suddenly.
• Defective inlet. Check other wall inlets.
• Power unit overcurrent protector
has been activated.
• Blown fuse or tripped circuit
breaker on house electrical panel.
• Thermoprotector has been
activated.
• Defective hose.
• Replace defective wall inlet.
• Turn the unit off by using the
power switch on the unit. Check
the overcurrent protector button
located on the left side of the
power unit (push to reset the
system). Turn unit back on.
• Replace fuse or reset circuit
breaker on house electrical panel.
• Turn the unit off by using the
power switch on the unit. Wait
30 minutes to let the unit cool
down. Turn unit back on.
• Replace hose as required.
3. Power unit
fails to stop
when the
hose is
removed.
• An electrical short has occurred
somewhere in the system.
• A complete check of all wall inlets
and power unit low voltage control
leads connections.
