Troubleshooting - Decrease in suction strength

Mvac

Situations

1. Motor guard screen is blocked.
→ Remove filters, and check the guard screen (which separates the motor from the filtration compartment) for blockage. Make sure filters are always properly installed, to prevent this problem from happening again.

2. Open vacuum inlet.
→ Close all vacuum inlets not in use. 

3. Exhaust line is clogged. 
→ Verify that no object is blocking the exhaust. 

4. Blocked hose.
→ Plug the handle end of the hose into the suction inlet, thus reversing the suction in the hose. Cover the gap around the handle, to ensure suitable suction strength, and ensure contact with inlet contacts to start the unit. This should clear the hose. 

5. Obstruction in the piping system. 
→ Loosen the clamp collars around the air intake to free the central vacuum unit from the piping system. Start the unit by plugging the hose into a vacuum inlet. By placing your extended hand over the air intake opening on the unit, check the suction strength on the unit itself. If suction 
strength is normal, the obstruction is in the piping system. If suction strength is diminished or completely absent, have the unit checked by an authorized service center. 

6. When I use my Hybrid central vacuum cleaner without a bag, will it decrease the suction power?
→ No, whether or not using a bag in a Hybrid vacuum cleaner does not affect the suction power in any way.
