1.2 Application
Comfort ventilation EXHAUSTOVEX isused forcomfort ventilationtasks. Operatingtemperature 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 or-
dered for outdoor installation (accessory Outdoor, OD).

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 requirements of the operating area.
Bends Aductbendmaybefitted immediately after the unit,becausetheairflowinthe spigot
has a uniformly moderate speed profile, which results in negligible system pressure
loss.
3004708-2016-10-03 Product information

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 pro-
tective net to the spigots with a maximum mesh width of 20 mm.

Cabinet The inside and outside of the cabinet is made of Aluzinc® The cabinet is insulated
with 50 mm mineral wool.
Fans The unit contains two centrifugal fans for exhaust air and supply air.
Counter flow heat
exchangers The unit's counterflow heat exchangers are made of aluminium and are highly effi- cient. The counterflow heat exchangers can be taken out and cleaned. See section
"Servicing".
Filters There are integral panel filters on both the extract air and outdoor air sides.
Bypass design The unit has a built-in double modulating bypass. In the case of summer operation
without heat/cold recovery, both outdoor air and extract air are directed around the
heat exchanger to reduce energy consumption.

2. Handling
2.1 Unpacking
Supplied compo-
nents The following components are supplied: ●VEX unit with associated base.
●Supplied accessories (as indicated in the checklist on the front page of the in-
structions)
Packaging The unit is delivered in three sections on separate disposable pallets; packed in
cardboard and clear plastic. The base is packed in a wooden box.
Unpacking Depending on the installation site's spatial limitations, unpacking can be done in the
following manner:
●Unpack and assemble the base and sections and subsequently transport the
VEX unit to the site or
●set up the base at the installation side and mount the sections on the base
afterwards.
Base assembly is described in section 3.1.
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 con-
nected 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 Move the VEX unit using a lifting or fork-lift truck or crane, as described in the in- structions "Transport of VEX350-360-370".
2.2.1 Passage through openings
The sections' princi-
pal dimensions Measurements are based on the exact dimensions of the VEX unit.

Width The list below shows the unit’s dimensions, and is intended to indicate how large an
opening has to be for the unit to pass through:
If the opening width is Then
Less than 900 mm The unit will not pass through
Between 900 - xxxx mm Remove doors and the support bars which the central
doors are fixed to – as described in section "Internal
transport with reduced weight".
Greater than xxxx mm The unit can pass through
2.2.2 Internal transport with reduced weight
Weight reduction The weight can bereduced during transport by removing the service doors, fan units
and counter flow heat exchanger. The table below shows the how much weight is
reduced when the subcomponents are removed.
Section Subcomponents Weight
Fan section, 2 x 156 kg Fan section, empty cabinet 101 kg
Door 19 kg
Fan unit 32 kg
Compact or bag filters, 2 items of 2 kg
