TIP: If you use our very convenient stretch hose, but require more suction power or don't like the pullback of the stretch hose, we recommend you try our traditional central vacuum hose. Part # A007
IF MOTOR SUDDENLY STOPS:
The most common cause is a clogged hose. Disconnect vacuum hose from power unit, hold one end high up in the air and drop a quarter or similar object into the hose. If the quarter gets stuck the hose is clogged. Try to unclog the hose with a long stick or see below "Cleaning the hose"
The bag is overfilled or fine dust like dry-wall dust or flour has clogged the bag.
The vacuum cleaning tools are clogged.
Vacuuming large amounts of dust other than household dirt, such as dry-wall or fine wood dust can block the bags pores fast, even if the bag is fairly new.
The motor filter is dirty and should be cleaned or replaced.
If vacuum unit is installed in an air tight compartment the exhausting air cannot escape, the motor can overheat and shut off until it cooled down and is restarted. You would have to cut a hole in the compartment and cover it with a louver to allow proper ventilation.
CLEANING THE HOSE:
Lift the hose up on both ends and dispense some liquid detergent into both ends.
With a garden hose, holding both ends still up, fill 3/4 with water.
Shake hose up and down, let detergent loosen the dirt.
Stretch the hose as far as you can and wash the dirt out with the full pressure of the garden hose. Repeat if necessary.
Hang hose up, let hose drain and dry completely, it might take 24 hours.
