7.2 Cylinder maintenance
The life of the cylinder depends on a number of factors, including: the amount and type of mineral in the water, the correct use and sizing of the humidifier, and the
output, as well as careful and regular maintenance.
IMPORTANT WARNINGS
The humidifier and its cylinder contain live electrical components and hot surfaces, and therefore all service and/or maintenance operations must be performed by
expert and qualified personnel, who are aware of the necessary precautions. Before performing any operations on the cylinder, check that the humidifier is
disconnected from the power supply. Remove the cylinder from the humidifier only after having drained it completely using the manual “ drain ” button or procedure.
Check that the model and the power supply voltage of the new cylinder correspond to the data on the rating label.
