On receipt of the product we recommend that you to check the following: 1- That it is the correct size. 2- That it is the correct model.
Electrical connection The SILENT is an extractor designed for a single phase supply, with voltage and frequency as indicated on the rating plate of the unit.

ATTENTION: When the humidity rate is above the selected value, the automatic option takes precedence over the manual and the unit cannot then be switched off using a switch. The desired humidity level is selected by means of a potentiometer “% Hr” positioned on the printed circuit board (fig.10) and accessible once the grille (1) has been removed.
GUARANTEE The SILENT-100 range products are covered by a five year guarantee, subject to the specified maintenance stated within this booklet. In the event of any failure of the fan within five years of supply- excluding only wilful or careless damage – we will exchange the fan free of charge.
