Installation
The air diffuser is normally suspended from the ceiling.
An M8 pop nut, i.e. a threaded grommet that facilitates
installation, is in the centre of the top of the air diffuser.
On the size 315 and 400 air diffusers, there are two M8
pop nuts for more stable mounting, see figure 1 and 3.
Commissioning
Commissioning should be carried out with the diffuser face
mounted. Pull the measuring tubes and the damper adjust-
ment cords out of the air diffuser through one disc in the
diffuser face. Then connect the manometer to the correct
measuring tube(s): two blue tubes for supply air and one
transparent tube for extract air. The rated coefficient of
performance of the air register can be used in a calculation
to determine the required commissioning pressure. Con-
clude commissioning by adjusting the damper to the cor-
rect blade position, tie a commissioning knot in the damper
cords to indicate the damper position. See Figure 1.
The K-factor is specified on the product’s identification
label and last in these instructions.
Maintenance
• Clean the air diffuser if needed with lukewarm water
and dishwashing detergent added.
• The duct system can be accessed and lightly pulling
the spring-loaded diffuser front downwards and then
tilting, see figure 2.
• Dismantle the perforated air distribution plate located
on the inlet as shown in figure 4.
• Loosen the damper in the inlet from its bayonet fastening
by rotating to the side.
