VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
— The distance between the side and bottom edges of the wall box and adjacent
surfaces should be at least 5 cm. The ventilation unit will be easier to operate if
this minimum distance is maintained. It also allows the air filter to be replaced
without obstruction.
— The lateral distance between two installation kits must not be less than 200 mm
to prevent an air short circuit between the ventilation units.

► If the room height is greater than 2.50 m, position the ventilation unit so that the
unit can be operated and filters can be maintained unaided (without steps, ladders,
etc.). Alternatively you can order a ventilation unit that can be operated externally.
NOTICE
Follow the notes in Table 2 on page 20 when planning the unit. This contains informa-
tion about the types of mains and control cable for each ventilation unit and the recom-
mended operating options.
3.3
Unrestricted access to the ventilation unit
The ventilation unit must always be freely accessible for operation and maintenance.
► Make sure that the ventilation unit is not covered or obstructed when the room is
subsequently decorated and furnished, otherwise it cannot be operated and it will not
be possible to replace the air filters. You should therefore maintain a clearance of at
least 15 cm in front of the ventilation unit cover.
► Make sure that the supply and extract air openings are not covered when the room is
subsequently decorated and furnished, otherwise the ventilation unit’s functions may
be impaired.
