Insert main lead plug into plug socket

Reset the fuse

Allow the extraction to cool down for approx. 5 minutes; if the cleaner does not start again automatically, contact the Service Department

At the end of the motor's service life (approx. 800 hours) the motor will be cut off suddenly. The motor or the brushes respectively needs to replaced.

Check function of connected electric tool or push in plug firmly.

The Vortex motor will be activated only, if the power consumption of the connected unit is higher than 6 watt. Some handpiece reaches this value at higher speed only. An adjustment of this activation level is not possible.

If the connected unit's lighting system fails, the power consumption drops to a value which doesn't allow the vortex motor to start. Please troubleshoot the connected unit first.

The Vortex motor will be activated if the power consumption of the connected unit is higher than 6 watt. Some handpiece reaches this value also in stand by mode. An adjustment of this activation level is not possible. But sometimes the problem can be solved by using an external multiple-socket outlet with master-slave control.

Replace dust bag

Clean or replace filter element

Clean suction hose

Empty tank

The Vortex is provided with a universal motor. This type of motor works with so called carbon brushes which are limited in their service life. Especially in case of the usage with a frequent start and stop (e.g. as a workbench extractor unit) may result in a reduced service life of the carbon brushes. This will cause an exchange of the brushes or motor by the Renfert service. In order to reduce such signs of wear the EC (Electronic Commuting) technology was introduced. Instead of the carbon brushes a electronic controlled magnetic field will be used for power transfer. This allows a 8 to 10 times longer service life compared to a universal motor. Needless to say that this motor technology causes a certain price difference. Our recommendation: If the extraction unit runs more than 1 hour per day, you should use a Vortex EC unit.
