5.5.4 Installing a combination exterior wall diffuser
To install the optionally available combination exterior wall diffuser, proceed as follows:
Step
Action
1
In the outer window element provided for this purpose, implement the openings for outside air (8) and outgoing ex-
haust air (9) with a diameter of 260 to 270 mm as follows:
1a
If you want to install the combination exterior wall diffuser (3) in an outer window element, replace the relevant window
with a window sandwich element (10) in which you implement the openings prior to installation (see chapter "5.5.3
Creating and inserting a sandwich window element" on page 30).
1b
If you want to install the combination exterior wall diffuser (3) in an outer wall, clarify the outer wall opening with AL-
KO THERM GmbH.
2
Remove the combination exterior wall diffuser (3) from its packaging; remove the packaging from your working area.
3
Remove the inside cover (5) from the combination exterior wall diffuser (3).
4
Apply sealing compound (12) to the housing of the combination exterior wall diffuser (3) to seal with the sandwich
element (10).
5
Insert the combination exterior wall diffuser (3) from the outside into the sandwich element (10) as far as it will go.
Apply light pressure to ensure sealing.
6
From the interior, slide the inside cover (5) over the exhaust air fitting (2) and the outdoor air fitting (7) as far as it will
go.
7
Drill the six fixing holes of 6.5 mm through the holes of the inside cover (5) into the sandwich window element (10).
Drill completely through the support material of the window sandwich element, but not through the sheet metal of
the rear wall (13) of the combination exterior wall diffuser (3) to ensure that the sheet metal screws can be securely
fastened.
8
Screw the six 5.5 x 45 mm self-tapping screws for the screw connections (6) through the inside cover (5) into the
sandwich window element (10) and tighten them by hand using a suitable screwdriver.
9
Seal the inside cover (5) with sealing compound (12) to the exhaust air fitting (2) and to the outdoor air fitting (7).
10
Do not carry out further work on the combination exterior wall diffuser (3) until the seals have hardened. Observe the
manufacturer's data for the sealing material.
11
Check that the mounted combination exterior wall diffuser (3) is secure and that it is horizontal with the sandwich
element (10).
12
Ensure that the exhaust air outlet (1) and the outdoor air intake (4) are not misaligned.

Installing the piping
5.6.1 Safety
WARNING
Risk of damage to property due to the action of uncontrolled forces
There is a risk of property damage or total damage if uncontrolled forces act on the piping or
pipe sockets.
No forces may be dissipated or loads deposited on the pipe sockets of the compact air
handling unit and the combination exterior wall diffuser.
Always adequately intercept the piping and do not allow it to sag.
Observe the manufacturer's data for the proper installation of the piping.
Damage caused by improper installation shall be at the expense of the initiator.
ATTENTION
The piping of the compact air handling unit via pipes or hoses must be implemented on site.
