Symbols, terms and warnings
Prohibition symbol Failure to observe instructions marked with a prohibition symbol
may result in serious or fatal injury.
Danger symbol Failure to observe instructions marked with a danger symbol
may result in personal injury and/or damage to the unit.
Scope This instruction manual is for use with EXHAUSTO VEX-type air handling units.
Please refer to the product instructions regarding accessories and extra equip-
ment.
The instructions must be fully observed to ensure personal safety and to protect
the equipment and ensure its correct operation. EXHAUSTO A/S accepts no liabil-
ity for accidents caused by equipment not used in accordance with the manual’s
instructions and recommendations.
Supply air/extract
air

● Supply air (air blown in)
● Extract air (air removed)
● Outdoor air
● Exhaust air
Left/Right The term R for Right, indicates the supply air is to the right of the cooling unit, as
seen from the operating side. The term L for Left, indicates the supply air is to the

Opening the unit Do not open the service doors before the supply voltage has
been disconnected at the isolation switch and the fans have
stopped. The isolation switch is positioned on the left side of the
connection box on top of the unit.
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 han-
dling unit during
operation
The VEX unit must always be locked
during operation:
● Use the cylinder lock in the han-
dle. Remember to remove the key
from the lock.
● Or use a padlock. Use the han-
dle’s built-in padlock fixture.

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).
1.4.1 Spatial requirements
The drawing below indicates how much space is needed for servicing, replacing fil-
ters, cleaning, etc.
2300
704
1470
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
3005031-2018-02-22 Product information
8/32

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.

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 from dirt and
dust.
When fitting without separating the
sections:
When fitting where the sections have
been separated:
● 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
● After it has been in operation for a
short period, the VEX unit must be
vacuum-cleaned inside to remove
debris that may have accumulated
from the duct connections
● Once the unit is fitted, it must be
checked and thoroughly cleaned.
All dust, debris and metal shavings
must be vacuumed up
