5.1 Installation general
Installation must take place under:
uality requirements ventilation systems dwellings.
uality requirements balanced ventilation in dwellings.
The regulations for ventilation of dwellings and residential
buildings.
The safety regulations for low-voltage installations.
The regulations for connection to interior sewers in dwell-
ings and residential buildings.
Any additional regulations of the local utilities.
The installation instructions for the Renovent Sky 150
In addition to the above design and installation requirements
and recommendations, the national building and ventilation
regulations must be complied with.

The Renovent Sky 150 can directly be mounted to the wall or
ceiling using the mounting brackets supplied for that purpose.
Because of the appliance’s weight, mounting the

The Renovent Sky can directly be mounted to the wall/ ceiling
using the suspension brackets supplied for that purpose. For a
vibration-free result the appliance must be mounted to a solid
wall with a minimum mass of 200 kg/m

. A gypsum block or
metal stud wall does not suce Additional measures such as
double panelling or extra studs are required in that case. In ad-
dition, the following aspects must be taken into account.
The appliance must be placed level.

The installation room must be such that a good condensate
discharge with air trap and pitch for condensate can be made
.
We recommend not to install the heat recovery unit in spa-
ces with an average high RH (for instance bathroom). That
will prevent condensation on the outside of the heat reco-
very unit.
Make sure that under no condition the condensate
discharge is installed at a pitch towards the appli-

The heat recovery unit must be installed in an insulated,
frost-free room to prevent, among other things, freezing of
the condensate discharge
When mounting exible ducts, bear in mind that it must be
possible to replace them in due course.
Make sure there is sucient free space at the appliance to
allow cleaning of the lters and maintaining the appliance. It
must be possible to swing the door open.
Avoid the use of petroleum-based adhesives in air plant sys-
tems.
Dwellings with construction moisture must be ventilated nat-
urally during a certain period
Ceiling mounting:
At least 70 cm at the underside of the appliance and a free
headroom of 1.8 m; if 70 cm free space is not available,
for instance when mounting on top of a suspended ceiling,
there must be sucient room to partly open and remove the
front panel.
The front panel can be detached after removing a lock
VFUHZDWWKHKLQJH(§ 3.4 / nr. 6)
Make sure the lters can always freely be removed, so there
is no frame or other obstacle at the level of the lters
Wall mounting :
Make sure there is a free space of at least 70 cm at the front
of the appliance and a free headroom of 1.8 m.
Make sure there is at least 20 cm free space at the appli-
ance side where the electric connections are located, so
connectors and sleeves remain accessible.
Air ducts:
The air ducts must be mounted air-tight
The air ducts to and from the dwelling must be tted with a
muer.
Mounting of air ducts to the roof deck must be avoided in
order to prevent sound transmission.
It is recommended to restrict the external duct pressure in
the design to 100 Pa at the design ow rate in order limit
the total sound level. In all events the practical external duct
pressure must be limited to 150 Pa.
The air velocity must be limited to 5 m/s in the main ducts
and 3,5 m/s in the branches.
To prevent condensation on the outside of the outdoor air
supply duct and the air exhaust duct downstream of the
Renovent Sky, these ducts must be provided with an exter-
nal vapour barrier as far as the appliance. If thermally insulat-
ed piping is used here, additional insulation is not necessary.
