1.3.2 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:
● flat
● level (+/- 3 mm per metre)
● hard
● resistant to vibration
See section "Principal dimensions" for positions of VEX unit feet.
1.3.3 Condensation outlet
The condensation outlets from the condensation tray under the heat exchanger and
any cooling coil exit the VEX unit from the front. An outlet for condensation water
must be installed in the immediate vicinity of the VEX unit. See section "Mechanical
installation"
NB:
To ensure space for the water trap, the VEX unit may be mounted an a base (ac-
cessory) or otherwise raised by min. 135 mm above floor height.
1.3.4 Requirements for duct system
Duct connection
To achieve maximum performance and minimal energy consumption, the VEX unit
should be connected to the duct system with a straight duct at least 500 mm long,
before and after the unit.
Silencers
The duct system must be fitted with silencers specified by the Project Manager, in
accordance with the requirements of the operating area.
Insulation
The duct system must be insulated against:
● Condensation
● Sound emission
● Thermal loss
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.
