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 2 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 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. 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 2.
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 1.
• 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.
