Optionally the boom ca has the side adjustment hydraulically, done

IRIS system setup
The IRIS application system is standard equipped with ceramic hollow
cone nozzles. Each drop leg holds 8 nozzles per drop leg. If a curtain
area of the canopy is not meant to be sprayed, a small valve is fitted as
per two nozzles that allow turning of the spray mist. If only one nozzle
is needed in that area it is as well possible to fit a blind cap.
In the valve A that allows the spray mist to pass on the nozzle, there
is a small no drip valve, that secures when the main switch turns of
the spray mist, that all nozzles stops instantly, and do not spill on the
ground.
The nozzles B are fitted in an adjustable support, in order to angle
them forward accordingly to forward speed, and there by not loosing
spray mist behind the sprayer.
The air outlet has an indicator C that shows the angling of the air
wanes E which are adjusted by pressing bottom D in, and then move
up or down the vanes E.
The air outlet in the lower part shall be orientated upwards to get the
spray mist penetrating from down and upwards. The upper spout shall
point downward in order to avoid drift. Those setting are accordingly
to grot hog the canopy, and adjustment is necessary during the
season, as the size of the canopy change.
In order to get the optimal cross flow effect and penetrate the canopy
the IRIS drop leg shall be set 10º , 15º , 20º or 30º forward, as indicated
in the adjustable part in the top of the drop leg. The forward angling is
set accordingly to forward speed while spraying.
