Installation
• Installation with the ROWT, see page 1, Figure 1.
• Installation with the ALV, see page 2, Figure 2.
Installation with the ROWT
1. The ROWT 1 commissioning box and the ROWT 2
connecting duct should be built into the wall. Cut the
opening in the wall structure for the ROW supply air
wall terminal according to the dimensions specified in
the dimension table and the dimension print.
2. Insert the mounting plate into the ROWT 1 commis-
sioning box.
3. Mark the positions for the bore holes.
4. Bore the screw holes.
5. Secure the mounting plate with screws to the wall.
N.B.! The screwheads should have a height of max. 4
mm above the plate surface.
6. Secure the wall terminal face using steel blind rivets.

Commissioning with the ALV
Commissioning should be carried out with the wall
terminal face mounted. Pull the measurement hose and
damper adjustment cords out of the wall terminal through
the perforation. Connect a manometer to the measuring
tube. The desired commissioning pressure can be calcu-
lated using the rated coefficient of performance (K-factor)
of the wall terminal. Set the damper to the correct blade
position, tie a commissioning knot in the damper cords to
indicate the damper position. Then lock the cords against
the locking screw in the air distribution baffle. See Figure
2.
If the ROWT connecting duct accessory is used, we rec-
ommend installing a type CRM commissioning damper
upstream of the wall terminal for adjusting the airflow
rate.
The K-factor (COP) is specified on the product’s identifica-
tion label. K-factors are also specified in the relevant com-
missioning instructions available for download at www.
swegon.com.
Maintenance
The wall terminal can be cleaned, if necessary, using
lukewarm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle. The duct system is
accessed for cleaning by boring out the steel blind rivets
and then withdrawing the wall terminal out of its spring
retainers. If an ALV commissioning box is used, withdraw
the acoustic baffle, move the distribution plate to the
side, turn and withdraw the damper from its holder from
the inlet. See Figure 2.
