Commissioning box:
ALV. Made of galvanized sheet steel. Contains removable
commissioning damper, fixed measurement tapping and
air distribution baffle. The commissioning box is available
with two different connection options: rear and side con-
nection respectively.
Cover plate:
ALVT 1. For the aesthetic installation of the ALV commis-
sioning box.
Installation
Cut an opening in the wall according to the wall opening
dimensions specified.
Place the commissioning box in the opening.
Insert the mounting frame into the commissioning box
and secure it by means of screws in the short sides to the
commissioning box and to the wall structure.
The assembly and dismantling of the component parts are
shown in Figure 3.
Press the diffuser face to engage it in the mounting frame.

Commissioning
Commissioning must be carried out with the diffuser face
in place. Pull the measuring hose and damper adjustment
cords out of the air diffuser through a nozzle. Connect a
manometer to the measurement hose. The desired com-
missioning pressure be computed by applying the rated
coefficient of performance of the air diffuser. 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.
The rated coefficient of performance (K-factor) is speci-
fied on the identification label of the product and in the
relevant commissioning instructions at our website.
Maintenance
Clean the air diffuser when necessary using lukewarm
water with added detergent. The duct system can be
accessed after opening the diffuser face by pulling it down
from the upper edge, withdrawing the air distribution
baffle and lowering the fully open damper. See Figure 3.
