Problem | Possible cause | Corrective action |
---|
Vacuum will not start | The electrical power is not connected properly | Ensure that the power cord is plugged into a dedicated grounded electrical outlet, according to specifications on pages 14 – 18 in the owner’s manual. |
Low voltage wire not connected properly | Verify the low voltage wires, make sure they are properly inserted into the low voltage inlet, as per instructions on page 17 in the owner’s manual. |
Faulty vacuum inlet | Start the vacuum unit from other inlets in your home, to identify the defective inlet. |
Vacuum will not start (cont.) | Unit circuit breaker is off | Press the reset button to reset the unit circuit breaker. If unit restarts and automatically shuts off shortly after, contact an authorized service center. |
In-house circuit breaker is off | Reset the circuit breaker in your electrical panel. Verify that your central vacuum unit is connected on a dedicated grounded circuit (see pages 12 – 14 in the owner’s manual). |
Defective on/off hose | Turn the hose 1/4 turn in the vacuum inlet. If unit starts, have the vacuum hose checked by a certified service center. |
Vacuum will not stop | Hose improperly inserted into vacuum inlet | Ensure that the hose end is properly placed in the vacuum inlet: the tab on the hose should fit into the slots on the inlet, to ensure adequate contacts for the hose switch to function (see page 18 in the owner’s manual). |
Defective on/off hose | If the hose is properly placed in the vacuum inlet, and the unit continues running despite the fact that the hose switch is in the “off” position, have the hose checked by a service center. |
Vacuum will not stop | Low voltage wire not connected properly | While vacuum is on, unplug low voltage wires from unit. If vacuum stops, there’s a faulty low voltage wire. Contact your installer or authorized service center. |
