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
adjustment cords out of the air diffuser through one
nozzle in the diffuser face. Then connect the manome-
ter 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 commissi-
oning pressure. Conclude commissioning by adjusting the
damper to the correct 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.
