Installation
See Figure 1.
1. Cut an opening in the wall according to the wall ope-
ning dimensions specified.
2. Place the commissioning box in the opening.
3. Insert the mounting frame into the commissioning box
and secure it with screws in the short sides to the com-
missioning box and to the wall structure.
4. The assembly and dismantling of the component parts
are shown in Figure 1.
5. Press the diffuser face to engage it in the mounting
frame.
Commissioning
Commissioning should be carried out with the diffuser
face mounted. Pull the measurement hose and damper
adjustment cords out of the air diffuser through the per-
foration. Connect a manometer to the measuring tube.
The desired commissioning pressure can be calculated

5. Mounting frame + air diffuser
using the rated coefficient of performance of the air dif-
fuser. Set the damper to the correct blade position, tie a
commissioning knot in the damper cords to indicate the
damper position. Then lock the cords against the locking
screw in the air distribution baffle.
The rated coefficient of performance (K-factor) is specified
on the identification label of the product and in the rele-
vant commissioning instructions at www.swegon.com.
See Figure 1.
Maintenance
The air diffuser can be cleaned, if necessary, using luke-
warm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle. The duct system
can be accessed after the air diffuser section has been
removed, the acoustic baffle has been withdrawn, the air
distribution discs have been moved to the side and the
damper has been turned and withdrawn from its holder
from the inlet. See Figure 1.
