Prohibited The VEX unit is not to be used to transport solid particles or in
areas where there is a risk of explosive gases.
No duct connection If one or more of the spigots is not connected to a duct: Fit a
protective net to the spigots with a maximum mesh width of 20
mm (in accordance with EN294).
Lock the air handling unit during operation
The VEX unit must always be locked
during operation:
● Use the cylinder lock in the handle. Remember to remove the
key from the lock.
● Or use a padlock. Use the handle’s built-in padlock fixture
Information plate The VEX unit information plate
shows:

1.3 Application
Comfort ventilation EXHAUSTO VEX is used for comfort ventilation tasks. Operating temperature range
for the unit – see section "Technical data".
Prohibited uses The VEX unit is not to be used to transport solid particles or in areas where there
is a risk of explosive gases.
1.4 Location requirements
Positioning The air handling unit is designed for indoor fitting. The air handling unit can be
ordered for outdoor installation (accessory Outdoor, OD).
1.4.1 Spatial requirements

Product information

1.4.2 Requirements for underlying surface
When fitting the unit directly, the surface must be:
● flat
● level
● hard
● resistant to vibration
1.4.3 Requirements for duct system
Silencers The duct system must be fitted with silencers specified by the Project Manager,
which meet the requirements of the operating area.
Bends A duct bend may be fitted immediately after the unit, because the airflow in the
spigot has a uniformly moderate speed profile, which results in negligible system
pressure loss.
Insulation The duct system must be insulated against:
● condensation
● sound leakage
● heating/cooling losses
Condensation Condensation in the ducts may occur when the exhaust/outdoor air has high hu-
midity. EXHAUSTO recommends a condensation outlet is also fitted at the lowest
point in the ducts.
No duct connection If one or more of the spigots is not connected to a duct: Fit a
protective net to the spigots with a maximum mesh width of 20
mm.
