Disconnect all poles of the mains cable intended for connection to the ventilation unit from the power supply before
carrying out installation and maintenance work.

Optional accessories, such as sensor modules and wireless or wired operating modules, must be fitted into the unit

If necessary, the internal control unit on the bottom cover of the interior cover must also be moved before installation in
the dismantled state.
1. Adjust the installation length of the unit either to the wall thickness or to the measure of length of the wall mounting pipe
by shortening the EPP housing extension.
2. Remove the interior cover from the bottom cover, whilst considering the explanations given in 3.3.1.1, section 2.
3. Take off the cover for the electrical connection by undoing the yellow PVC nut.
4. Insert the unit, together with the bottom cover of the interior cover, as far as it will go into the wall mounting pipe, whilst
considering the position of the openings for the electrical connections.

If necessary, a suitable tool can be used to remove the centring spring raised 5 mm, and arranged 3 times on the
EPP housing, to the dimension  300 of the EPP basic body, in order to facilitate the insertion.
NOTE
The cut must be performed all around, perpendicular to the axis of the EPP
pipe extension.
