Installation
Suspend the air diffuser with hangers from the ceiling. An
M8 pop nut, i.e. a threaded grommet that facilitates instal-
lation, is provided at the top and in the centre of the air dif-
fuser. On the size 315 and 400 air diffusers, there are three
M8 pop nuts for more stable mounting. Figure 1.
Commissioning
Commissioning should be carried out with the diffuser face
mounted. Pull the measuring tubes and the damper adjust-
ment 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 per-
formance 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
The air diffuser can be cleaned, if necessary, using lukewarm
water with dishwashing detergent added or by vacuum
cleaning using a brush nozzle.
The duct system can be reached for cleaning by removing
the diffuser face plate. The perforated air distribution plate
and damper in the commissioning box can be removed by
turning the wing nuts, positioned on each side of the inlet,
¾ of a turn. See Figure 1.
