Installation
Secure the air diffuser with screws to the wall using angle
brackets supplied with the diffuser. Screw the base into
place on the bottom of the unit. Secure the telescopic
duct cover with screws to the wall using the wall mount-
ing rails. Conceal the screws with aluminium lateral strips.
Press the regulator unit, which has a circular connection
spigot with a rubber seal, into the inlet socket of the air
diffuser. See Figure 1.
Commissioning
The measurement tapping is positioned on the one
side of the air diffuser behind the aluminium strip. The
K-factor (COP) is given on the product identification label
on the diffuser to the side of the measurement tapping.
K-factors can also be found in the relevant commissioning
instructions at www.swegon.com. We recommend that
you use the REG regulator unit for adjusting the airflow.
See Figure 2.
To regulate how the air is supplied to the room, turn the
air diffuser’s Varizon®discs to make the air to flow in the
desired direction. A straight air discharge can be achieved
by taking the disc out of the diffuser, turning it 180° and
reinserting it back into place. See Figure 4.
Maintenance
The air diffuser can be cleaned, if necessary, using luke-
warm water with dishwashing detergent added or by
vacuum cleaning using a brush nozzle. The duct system is
accessed by removing the front panel and the inspection
cover of the air distribution panel. See Figure 2.
