Installation
The air diffuser is normally suspended from the ceiling. An M8
pop nut, i.e. a threaded grommet that facilitates installation,
is provided at the top and in the centre of the air diffuser. On
sizes 315 and 400, there are two M8 pop nuts for more stable
mounting, see figure 3 and 4.
Commissioning
Commissioning should be carried out with the wall dif-
fuser face mounted. Pull the measuring tubes and damper
adjustment cords out of the air diffuser through the hole
in the front. Then connect the manometer to the cor-
rect measuring tube(s); A transparent measuring tube for
extract air. The rated coefficient of performance of the
air diffuser can be used in a calculation to determine the
required commissioning pressure. Conclude commission-
ing by adjusting the damper to the correct blade position,
tie a commissioning knot in the damper cords to indicate
the damper position. See Figure 3.
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 face downwards and then
tilting, see figure 2.
• Dismantle the perforated air distribution plate located
on the inlet as shown in figure 5.
• Loosen the damper in the inlet from its bayonet fasten-
ing by rotating to the side.
