2. Installation

2.1 Ventilation unit installation site

The temperature in the space where the unit will be
installed must be more than +10 °C. The ventilation unit
can be installed in a machine room, store room, etc. The
ventilation unit can be installed in a machine room, stor-
age space, etc.
The ventilation unit should not be secured to a wall that bor-
ders to a living room or a bedroom due to the risk of noise.
During installation, arrange electric and control cables to
make them easily accessible.
The ventilation unit can be mounted either on the wall
in a wall mounting bracket or on the ceiling with a
mounting frame. The mounting frame required can be
purchased separately as an accessory.
The unit should be mounted as near as possible to a wall
or ceiling. The space between the ventilation unit and the
wall should be insulated so that the sound from the unit
will not be transmitted out through the rear wall.
Connect the extract air from a CASA cooker hood, if
installed, via a duct to the extra duct connection spigot
on the top side of the ventilation unit, which on delivery
is plugged.

2.1.1 Wall mounting

Mount the ventilation unit on a wall by means of a wall
mounting bracket which is available as an accessory.
If the wall is composed of vertical studs and wall boards,
the wall must be reinforced with horizontal studs that
will support the weight of the unit. Swegon also recom-
mends that the wall be insulated with mineral wool or
similar insulation for preventing sound from propagat-
ing to other rooms.

Screw the wall mounting firmly in horizontal position
onto the wall where a wall stud will support the weight
of the unit.
Screw the adjustment feet in position on the lower edge
of the rear wall of the ventilation unit before lifting the

Lift up the ventilation unit onto the wall mounting
bracket so that the ears on the bracket engage in the
corresponding notches at the top on the backside of
the unit. The ventilation unit's heat exchanger can
be removed to make it easier to lift the unit. See the
"Servicing" Section.
Set the final position of the ventilation unit with the
help of the adjustable feet so that the ventilation unit
tilts backwards slightly.

2.1.2 Ceiling mounting

The ventilation unit can also be mounted in a ceiling
mounting frame (available as an accessory) on the ceiling.
Fasten the ceiling mounting frame in ceiling anchor
sleeves with four M8 threaded rods. The length of rods
must be adjusted so that they will be positioned approx.
15 mm under the inner surface of the ceiling mounting
frame. Install at least three threaded rods in the corners
of the ceiling mounting frame. To avoid a possible col-
lision with the ducts, one of the threaded rods can be
located in the hole next to the corner.
Screw in the M8 nuts onto the threaded rods to such
a height that the ceiling mounting frame will be
