12.1. SUPPLY UNITS / EXHAUST GRILLES
For good supply air distribution, it is important that the stream should be able to stick to the wall or
ceiling. This requires placing the units less than 20 cm from the ceiling and making sure that the
stream of air does not cause discomfort for the occupant (draught, etc.).
In order to ensure good air change in all parts of the room, it is generally necessary to
avoid placing the unit too close to doors of the main rooms.
12.2. FRESH AIR INLET AND EXHAUST AIR OUTLET
The fresh air intake and the used air discharge must be in direct contact with the outdoor,
and not in an attic, garage, or crawl space.
The fresh air intake of the installation must be:
·as far as possible from sources of pollution and air discharges (at least 3m from the ground);
·if possible, on a protected façade.
The exhaust air, for its part, must be far from air intakes (fresh air inlet, doors and windows); it
must not be a nuisance for the occupants. If possible, use a different façade from the air intake in
order to avoid mixing between the fresh air and the stale air.
We recommend taking the prevailing winds into account, in order to avoid an overpressure in the
supply or exhaust duct (discharge up, or horizontal, and favourably oriented with respect to the
prevailing winds).
Requirement for fresh air inlet / exhaust air outlet grilles:
·Ø 160 mm
·less than 20 Pa at 230 m

/h
The use of a double used air/fresh air duct is not recommended for this type
of installation (Make sure that it avoids the mixing between the intake of
fresh air and the discharge of used air).
