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 or-
dered for outdoor installation (accessory Outdoor, OD).

The drawing below indicates how much space is needed for servicing, replacing fil-
ters, cleaning, etc.

RD11621-02
NB: A free height of at least 200 mm is required above the unit’s connection box.
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
3005063-2018-01-09 Product information
8/32

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.

2. Handling
2.1 Unpacking
Supplied compo-
nents
The following components are supplied:
● VEX unit
● Supplied with accessories (as indicated in the checklist on the front page of
the instructions)
Packaging The unit is delivered attached to a disposable pallet and packed in clear plastic.
NB Once the plastic has been removed, the unit must be protected against dirt
and dust:
●The covers on the spigots must not be removed until the spigots are
connected to the ventilation ducts.
●Whenever possible, keep the unit closed during fitting.
The unit should be
cleaned before it is
used.
Once the VEX unit is fitted, it must be checked and thoroughly cleaned. All dust,
debris and metal shavings must be vacuumed up.

tions
● Lift the fan sections and rotor section off the base. We recommend you place
these sections on pallets for further transport.
