or shuts off during normal
operation with no LED
showing Red or illuminated.

Possible Cause
1a. Disposable filter bag or debris bucket are completely full.
1b. 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.
1c. Obstruction in the tubing system inside the walls.
1d. Wall Inlet cover not properly sealed.
1e. Exhaust tubing or vent clogged.
2a. Defective inlet. Check other Wall Inlets.
