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
These instructions use the following terms as given in DS447-2013:
● 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
left.
Front page: Acces-
sories
The front page of the instruction manual contains a checklist, detailing the acces-
sories delivered with the VEX unit.
NB When retrofitting EXHAUSTO accessories, please update the checklist on
the front page.
Warnings:
Opening the unit Do not open the service doors before the supply voltage has been dis-
connected at the isolation switch and the fans have stopped. The isola-
tion 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.
1550
755
805
RD11665-01
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 to an existing surface - i.e. without using the mounting
base (accessory) - the surface must be:
● level
● horizontal (±3 mm per metre
● hard
● vibration-resistant
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.
3005007-2018-02-22 Product information
8/32

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 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.
2.2 Transport
Transport equip-
ment
Transport the VEX unit in one of the following ways:
Method Drawing
Manual transport:
Lifting brackets for
manual transport can
be fitted as shown on
the drawing:

Method Drawing
Using pallet truck or
fork-lift truck:
Lift the VEX unit on the
disposable pallet.
IMPORTANT: If the
disposable pallet can-
not be used, the forks
on the lifting equipment
must be long enough
to prevent damage to
the bottom of the unit.
RD12463-01
Crane:
Never lift the
VEX unit
with the lift-
ing brackets
by using a
crane.
Use straps and lifting
yokes to prevent dam-
age to the unit.

Step Action
1 Remove the fixing screws on the sliding rail (out towards the oper-
ating side)
2 Loosen the bindings on the motor cable and the measuring hose
3 Pull the fan unit out to the end-stop (a screw on each rail acts as a
stop)
4 Remove the supply cable and modbus cable in the motor control
box
5 Remove the measuring hose which is fixed to the intake
6 Remove the two end-stop screws (one on each rail). The fan unit

3. Mechanical assembly
3.1 Installing the unit
Description The VEX unit is installed so that it is horizontal.
3.1.1 Installed directly onto the floor
The requirements for the floor surface must be met, see the section entitled "Re-
quirements for underlying surface", chapter 1.
NB After installation, check the VEX unit is completely level.
3.1.2 Installing on mounting base
The EXHAUSTO mounting base enables the air handling unit to be installed correct-
ly. The base is equipped with adjustable levelling screws, so that the air handling unit
can be fitted horizontally on a surface that is not level ( +/- 20 mm per metre). See
diagram no. 3002646 for installing on the mounting base.
