Maintenance
Vasco advices to clean the electric preheating element every 4 years.
1)
Remove the plugs of the ventilation unit and the preheating element from the sockets.
2)
Wait 10 minutes for the preheating element to cool down
3)
Take the preheating element off the installation
4)
Clean the metal elements inside the preheating element*
5)
Reinstall the preheating element onto the installation
6)
Put the plugs of the ventilation unit and the preheating element back in the sockets.
*Cleaning can be done with pressurized air and/or a small brush.
Do not use any chemical/liquids cleaners.
Failure to perform the maintenance work on time will ultimately result in the appliance no longer
functioning optimally.

Technical information
The preheating elements essentially consist of an insulated PTC heat register that is built into a
housing consisting of metal and plastic. The preheating element will be controlled by the software on
the circuit board of the ventilation unit.
