Commissioning box:
SWAN T: Made of galvanised sheet steel. The commis-
sioning box contains a commissioning damper and fixed
measurement tapping. The box is supplied with a connec-
tion in the long side (L).
Sound-absorbing material
Accessory for the commissioning box: Sound absorbing
material with reinforced surface layer. Fire resistance rated
to B-s1,d0 in accordance with EN ISO 11925-2.
Installation
The commissioning box should be suspended by means
of hangers from the ceiling. The box is equipped with
mounting fastening points, see Figure 2. Secure the dif-
fuser face to the commissioning box with screws through
the crosspieces in the commissioning box as shown in
Figure 3.
Commissioning
Commissioning should be carried out with the diffuser
face mounted. Pull the measuring tubes and damper-
adjustment cords out of the air diffuser through the slots,
blue measuring tube for supply air and transparent tube for
extract air, see Figure 1. When you have finished measur-
ing the air pressure and have determined the appropriate
damper position, stretch both damper-adjustment cords
and tie them together in a so-called commissioning knot.
K-factors are specified in the relevant commissioning
instructions at www.swegon.com.
Maintenance
Clean the air diffuser if needed with lukewarm water and
dishwashing detergent added. Or use a vacuum cleaner
with a brush nozzle for cleaning. The duct system can be
accessed after removing the diffuser face and the damper
assembly, see Figures 1 and 3.
