O pe r a tin g t he contro l unit wh i le s p r ay in g
The switches on the spray control box control the following func-
tions:
1. Power switch
2. Manual pressure regulation
3. Main ON/OFF
4. End nozzle (Left/OFF/Right)*
5. Foam marker regulation*
6. Foam marker (Left/OFF/Right)*
7. Boom section valves
8. Valve function A-B*
*optional equipment
In order to close the entire boom, switch ON/OFF (3) to OFF posi-
tion. This returns the pump output to the tank through the return
system. The diaphragm Non-drip valves ensure instantaneous clos-
ing of all nozzles.
In order to close one or more sections of the boom, switch the rele-
vant distribution valve (7) to off position. The pressure equalization
ensures that the pressure does not rise in the sections which are to
remain open.
On the sprayer, the bottom Suction Manifold valve should be turned
toward “Suction from Main tank”. The top Pressure Manifold valve
should be turned toward “Spraying” and the bottom Pressure
Manifold valve to “Agitation” if necessary.
If a spraying job has been interrupted for a while, severe sedimenta-
tion can occur depending on chemicals being used. When re-start-
ing spray job, it might be necessary to agitate sedimented material
first.
1. Make sure the control unit is switched off.
2. Turn the bottom Suction Manifold valve handle towards “Suction
from main tank”. Turn the top Pressure Manifold valve handle
towards “Spray” and the bottom Pressure Maniflold valve towards
“Agitation”.
3. Engage pump and set to operating r.p.m. (540/1000).
4. Agitation will start and should be continued for at least 10 min-
utes.
5. Once the chemicals are mixed, spraying can resume.
