3. Mechanical installation
The installer is responsible for safely and securely fastening the unit to the wall.
Note: When lifting the unit, it is important to place a protective underlay, to avoid scratching the base plate. The underlay
can consist of, e.g. thick cardboard or a similar material.
The mechanical installation involves
•Marking, drilling of holes for connecting ducts and mounting of wall frame
•Mounting of unit in wall frame
•Installation of pipes and grates through walls or over roof, depending on model
•Mounting of panels
Important: Before drilling holes in wall or roof, check that there is at least 0.5 m between the wall and the unit’s exhaust
end. If the exhaust end is facing out towards glass panes, that distance must be greater. If these minimum distances are
not observed, there is a risk of increased noise from the unit.

3.2 Mounting unit in wall frame
1
Start by finding the centre of
the wall frame using a ruler.
The centre measurement for
the wall frame is 62 cm. Mark
the measurement.
2
Next mark the middle of the
wall or the location you wish
to place the centre of the unit.
3
Now line up the two marks.
If you like, you can place the
wall frame all the way up to
the ceiling. If you do this,
there will be a 6 mm gap
between the top of the unit
and the wall.
4
Now that the wall frame is
provisionally hung, you can
mark holes for screws and the
centre of supply and exhaust.
The duct size is Ø200mm.
The recommended hole
diameter is Ø210-215 mm, so
the pipes can be insulated
subsequently.
5
Horizontally measure and
mark distance down to centre
of supply/exhaust, and mark
centre in vertical direction.

CODUME Page 9
6
This clearly indicates the
marking of the centre of the
intake hole.
Note: The length of the two
pipes depend of the wall-
thickness.
7
All necessary markings show.
Note: The holes for the pipes
should have a downward start
of 1-2%, to prevent hard rain
from penetrating the unit.
8
Here, both holes have been
drilled, and the wall frame is
now securely fastened to the
wall.
Note: The screw type used
depends on the wall material.
9
Place the unit on a thick
underlay, such as cardboard
or the like, to prevent
scratches in the base plate. It
is important that the unit is
stable on the lift.
Note: Remember to remove
tape holding the discharge
damper in the transport
position.
10
The unit is on the underlay
and is safely and securely
placed on the lift.
In the picture on the right, the
unit is raised and can now be
adjusted to the two guide
hooks placed on the wall
frame.

CODUME Page 10
11
Make final adjustments to the
unit to unable it to be pushed
far enough over the hooks
that it cannot fall back out
again.
In the picture on the right, the
unit is hanging from the two
guide hooks.
At the bottom of the picture
one of the adjustment screws
shows.
12
Now, fasten the unit to the
wall frame, using the two
factory-supplied M8 bolts,
one on each side.
To get the unit to hang
properly relative to the wall,
adjust it by screwing the two
adjustment screws situated
just over the base plate.
Use a no. 13 screw wrench.
13
The unit must hang
horizontally; therefore, it is
important to check and
readjust.
