Remove the diusers and side brackets from the boxes. Inspect
each diuser for any cracks in the housing. Leave the covers
securely in the boxes (Image 1), as they will only be needed when
starting the painting.

Use screws to attach the side fasteners. They can be applied to 1
or 2 layers of plasterboard.
1 layer: the element is placed against the edge (Image 2);
2 layers: the fastening is aligned with the protruding brim in the
housing (Image 3).

Three installation methods are possible. You
will recognise which method is suitable for you
by looking at the images depicting dierent
situations. Choose the installation method
that best suits your situation and follow the
appropriate instructions.

Cut a hole for the diuser in the intended place (Image 1.1).
Tilt the diuser at an angle and insert it through the hole (Image
1.4). Then place it in the intended position (the side fastenings
must rest on the plasterboard).
Connection via a exible corrugated pipe
When planning the diuser installation points, make sure that
there are no ceiling frame proles in the diuser installation area.
Any proles present in the area of the cut-out hole and creating
an obstruction must be removed (Image 1.2). Be sure to consult
with the ceiling installers to ensure that you will not damage the
ceiling structure.
Check that the diuser installation is level. The diuser must
be ush with the ceiling surface or can protrude by up to 1 mm
(Image 1.5).
Attach the exible corrugated pipe to the diuser connector. A
clamp or plastic strap will suce (Image 1.3).
The diuser is fastened with self-tapping screws. Insert the
screws directly through the plasterboard into the side fasteners
(Image 1.6).

When connecting the diusers via a exible
corrugated pipe, the gypsum ceiling panels
must be already attached.
If the diuser is awry, the side brackets have
been attached at dierent levels. Remove the
diuser and readjust the fasteners.
The diuser is ready for nishing.
Go to the nishing instructions (page 11).

Connection via a plenum box (75 mm plastic duct system)
• If the plenum box is plastic, a successful installation will require
at least 7 cm of space from the duct to the bottom of the ceiling
prole (Image 2.5). If two layers of plasterboard will be used, the
distance required is 6 cm (Figure 2.6).

INSTALLATION METHOD NO. 2

Make sure that the gypsum ceiling structure does not interfere
with the installation of the diusers (Image 2.1).
Metal ceiling proles should be at least 7,5 cm away from the
connection pipe (Image 2.2).
Make sure there is enough space for a successful
diuser installation:
• If the plenum box is metal, a successful installation will require
at least 7 cm of space from the box housing to the bottom of
the ceiling prole (Image 2.3). If two layers of plasterboard will be
used, the distance required is 6 cm (Figure 2.4).
SHORTENING THE CONNECTION PIPES
The connecting pipes must be shortened by measuring Distance
A from the level of the lower prole surface (Images 2.7 and 2.8).

The diuser coupling is then inserted into the connection pipe
(Image 2.9). Continue moving the coupling inwards until it touches
the pipe (Figure 2.10).
Check that the diuser is level with respect to the visible
ceiling surface (Image 2.13). The visible edge of the diuser
must be ush with the ceiling or can protrude by up to 1 mm.
If the diuser is awry, the side brackets have been attached at
dierent levels. In this case, remove the diuser and readjust the
fasteners.
For 2 layers of plasterboard:
After attaching the rst layer of plaster, the diuser housing
should protrude by about 13 mm (Image 2.14). After attaching the
second layer, the housing must be ush with the plasterboard or
protruding by up to 1 mm.
After inserting the diuser, make sure that it is being held
securely and will not fall out while you prepare the ceiling panel. If
necessary, use mounting tape for a temporary fastening to prevent
the diuser from falling out (Image 2.11).
For 1 layer of plasterboard:
Cut out a hole in the required place and attach the board using
screws (Image 2.12).
The diuser is fastened with self-tapping screws (Image 2.15).
Insert the screws directly through the plasterboard into the side
fasteners.
The diuser is ready for nishing.
Go to the nishing instructions (page 11).

Rendering / reinforcement / painting
Fill the gap between the diuser and the plasterboard with putty.
We recommend using Knauf Fugenfuler or Uniott putty (Image
3.1).
Apply another coat of putty (Image 3.4). Once the putty has
hardened, rub it with a ne sandpaper.
When the putty has dried, cut out the breglass cloth in the central
part of the diuser. Use a sharp knife to cut it ush with the inner
edge of the diuser, while making sure not to damage the gypsum
housing (Image 3.3).
Cut out 35 x 35 cm sheets from a thin breglass cloth. Press the
breglass cloth into the putty, directly over the diuser area. When
pressing the cloth into the putty, smooth it out to ensure an even
covering with the layer of putty (Image 3.2).
The centre cover does not need to be plastered prior to painting,
as priming it will suce. Paint only the visible surfaces of the
centre cover (Image 3.6).
The entire inner surface of the diuser must be painted with the
ceiling paint (Image 3.5).
FINISHING INSTRUCTIONS
Prior to painting, impregnate the rendered
surfaces with a deep primer; use a moisture-
resistant primer for damp rooms.
In damp rooms, use moisture-resistant ceiling
paints that are specially designated for these
types of rooms.

We recommend using the Knauf nishing
technology for your nishing work.
Remove dust from surfaces and gaps. Use
Ceresit CT-17 or Knauf Tiefgrund primers.
To avoid cracks in the seam, we recommend
reinforcing the entire seam area with breglass
cloth.

When the paint is completely dry, the cover can be put in place.
The cover is attached to three magnetic holders (Image 3.7).
Adjust the magnetic holders so that each holder protrudes by 15
mm from the diuser housing (Image 3.8).
The diuser installation is now complete (Image 3.9).
Valve installation. Remove the diuser cover. Insert the exible
valve into the diuser connection branch. The air ow is regulated
by changing the number of valve segments (Image 3.10).
We recommend cleaning the diuser at least once a year. Use
a soft duster to clean the inside of the diuser, to prevent dirt
from accumulating and sticking to the device if it is left unclean for
prolonged periods of time. Accumulated dust can also be removed
with a vacuum cleaner. Avoid damaging the painted surface.
AIR FLOW REGULATION
DIFFUSER MAINTENANCE
The diuser cover must always be ush with
the ceiling.
If is it necessary to regulate the air ow, we
recommend the additional purchase and use
of an INNO valve. These come in standard
diameters of 100 mm, 125 mm or 160 mm.
To maintain a clean device, change the
actuator lters inside the air diuser regularly.
This will reduce the penetration of impurities
from outside and keep the diuser clean for
longer.
