Agitation before re-starting spraying
If a spraying job has been interrupted for a while, severe sedimentation
can occur depending on chemicals being used. When re-starting 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 minutes.
5. Once the chemicals are mixed, spraying can resume.
Operating the control unit while spraying
The switches on the spray control box control the following functions:
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 position.
This returns the pump output to the tank through the return system. The
diaphragm Non-drip valves ensure instantaneous closing of all nozzles.
In order to close one or more sections of the boom, switch the relevant
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.
