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 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 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.
