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
find examples of this in section 9.2 from page 21.
► Maintain the following minimum distances (see Fig. 4 and Fig. 5):
—
If there is no flat ductwork or flexible pipe system
connected using the
ductwork connection adapter:
the distance between the top edge of the wall box and the ceiling must be at least
150 mm to prevent an air short circuit.
—
If there is a flat ductwork or flexible pipe system
connected using the ductwork
connection adapter:
the distance between the top edge of the wall box and the ceiling must be at least
300 mm, otherwise there will not be enough space for connecting flat ductwork or
flexible pipes.
— The distance between the side and bottom edges of the wall box and adjacent
surfaces should be at least 50 mm (exception: if a condensate connection is used,
see (*) in Fig. 4 on page 10). 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 wall boxes 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 26 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.
