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.
