Scope This instruction manual is for use with EXHAUSTO VEX-type air handling units. Please refer to the
product instructions regarding accessories and extra equipment.
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 liability 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 operat-
ing 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 accessories delivered with
the VEX unit.
NB When retrofitting EXHAUSTO accessories, please update the checklist on the front page.
Warnings
Opening the air
handling unit
Do not open the service doors until 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.
RD13497-01
ON OFF
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).

1.2 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.
1.3 Location requirements
Positioning The air handling unit is designed for indoor fitting. The air handling unit can be ordered for outdoor in-
stallation (accessory Outdoor, OD).

RD13499-01
NB For servicing purposes, a free height of at least 200 mm is required above the unit’s connection box.
1.3.2 Requirements for underlying surface
When floor-mounting the unit, the surface must be:
● level (+/- 10 mm per metre)
● hard
● resistant to vibration
The VEX unit leg height can be adjusted: 55–110 mm.
1.3.3 Outlet
A condensation outlet must be installed in the immediate vicinity of the unit. See also “Mechanical fitting”
section.
1.3.4 Requirements for duct system
Silencers The duct system must be fitted with silencers specified by the Project Manager, which meet the re-
quirements 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 humidity. 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.
