Operating the Control Unit While Spraying - Spray Box III

EVC operating unit only
The switches of the spray control unit (Spray Box) control the following
functions:
1. Power ON/OFF. Turns the Spray Box power on or off.
2. Spray pressure regulation. Regulates the main spray pressure.
3. Main spray ON/OFF. Turns all sections on or off. Lever up is OFF and
down is ON.
4. Optional function (A/OFF/B). If extra equipment is added, it can be
controlled from here. Middle position is OFF.
5. End nozzle (Left/OFF/Right). If end nozzles are fitted, they can be turned on for each side. Middle position is OFF.
6. Foam marker blob interval. Foam marker equipment is not included from HARDI.
7. Foam marker (Left/OFF/Right). Foam marker equipment is not included from HARDI.
8. Distribution valves ON/OFF. Turns individual spray sections on or off. Lever up is OFF, and lever down is ON.
• In order to shut all nozzles, set the main spray 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 (8) to off position (upwards).
The pressure equalization (DF4, if installed) ensures that the pressure does not rise in the sections, which remain open.
• On the sprayer, the suction valve should be turned towards "suction from main tank" and the pressure valve should be
turned towards "spraying". Turn the agitation valve to "agitation" if needed.

Before Returning to Refill the Sprayer

If the sprayer is to be refilled at the farm, or at a fixed filling place without a filling space with hard surface and drain to a
closed reservoir, the sprayer should be rinsed before returning to refill.
Dilute the residues of the spraying circuit, and spray it on the crop. Depending on the weather conditions, it could also be
necessary to clean the sprayer on the outside now while in the field, before returning to the farm.
±
WARNING! Always follow local legislation in force at any time.

Parking the Sprayer

To avoid spot contamination, the sprayer should always be parked at either the washing/filling location or under roof.
This prevents rainfall from washing down chemical residues from the sprayer's surfaces.
• Parking at the washing/filling location will retain residues.
• Always park the machine out of reach of children, animals and unauthorized persons.
• Always follow local regulations when parking your sprayer.
