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.
