TROUBLESHOOTING GUIDE

Read before calling Service Center.

PROBLEMS POSSIBLE CAUSES POSSIBLE REMEDY

1.Loss or decrease of

vacuum occurs.

• Debris pail 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.

• Exhaust tubing or vent clogged.

• Empty debris pail as described on page 12.

• Insert handle end of hose into utility valve at

power unit. Turn unit on. This will reverse normal

air flow through the hose and dislodge any clogs.

• 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.

• Inspect and remove any blockages.

2.Power unit does not

start, or shuts off during

normal operation with

no LED showing red or

illuminated.

• Defective inlet. Check other wall inlets.

• Thermoprotector has been activated OR there is

a tripped circuit breaker on the unit.

• Blown fuse or tripped circuit breaker on house

electrical panel.

• Defective hose.

• Microprocessor lockup.

and VX12000C.

• Low line voltage.

• Replace defective wall inlet.

• Turn unit off for 20 minutes then plug unit back in.

If unit does not start, look for the tripped circuit

breaker behind the unit, a white button has

popped up, push it back to reset it. If circuit

breaker trips again, unplug your unit and contact

your local Service Center.

• Replace fuse or reset circuit breaker on house

electrical panel.

• Replace hose as required.

• 1) Push Reset button while unit is engaged OR

2) Unplug unit completely for 60 seconds.

• Contact your local Service Center.

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 lead connections.

Contact your authorized Service Center.

during normal operation,

lights on unit, wall valve

and hose are all red.

• Debris pail full sensing has been activated. • Empty debris pail as described in page 12.
