2.5.6 Mounting the unit to the roof cowl
Caution:
c
The unit cannot be suspended from the roof cowl.
One must always make use of a suspension
construction, such as a suspension frame, for
example.
1. Determine the height at which the unit must hang, and if
necessary, attach a channel section of the correct length to
the roof cowl.
2. Bring the unit to the correct height, so that the flange
1
comes within the rim of the roof cowl
2
.
3. Attach the roof cowl to the flange, using 12 screws.

Regulating the discharge direction
Set the nozzles to the angle which produces the most optimal
effect of the unit for the situation. For this purpose, the noz-
zles are equipped with a ball-and-socket joint.
The optimal angle of the nozzles depends on the mounting
height of the unit and on the floor surface area to be reached.
Note:
n
Measure all the values in metres.
1. Determine the diameter (
D
) of the floor surface area that
must be reached;
2. Measure the mounting height (
H
) of the unit. This is the
distance between the floor and the underside of the unit;
3. From the table, read out the angle (
α
) at which the noz-
zles must be set;
