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 to be reached.
1. Determine the diameter (
D
) of the floor surface 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;
Nozzle angle
4. Snip off the adjustment aid
1
(supplied) along the dotted
line which corresponds to the correct angle (
α
);
5. Hold the snipped-off adjustment aid
1
against the unit and
turn the nozzle
2
against the underside of the adjustment
aid;
Caution:
c
Do not aim the nozzles at walls or other obstacles
(such as scaffolding).
6. Repeat step 5 for all nozzles.
