Operating the control unit while spraying (Z-version) HC 5500

μ
ATTENTION! The following information is intended as a general guide only. For detailed information please refer to
the Controller HC 5500 / Spray Box III manual, supplied with your sprayer.
The switches of the spray control unit 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 valve ON/OFF. Turns all sections on or off. Lever up is OFF and
down is ON.
4. End nozzle (Left/OFF/Right). If end nozzles are fitted, they can be
turned on for each side. Middle position is OFF.
5. Foam marker blob interval. Regulates the blob interval for the
optional foam marker.
6. Foam marker (Left/OFF/Right). Turns the optional foam marker on for each side. Middle position is OFF.
7. Section valves. Turns single sections on or off. Lever up is OFF and down is ON.
8. Optional function (A/OFF/B). If extra equipment is added, it can be controlled from here. Middle position is OFF.
• In order to close the entire boom, switch main 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 (upwards). The
pressure equalisation ensures that the pressure does not rise in the
sections that remain open.
On the sprayer the suction valve should be turned toward "Suction from
Main tank" and the pressure SmartValve should be turned toward
"Spraying". Turn the agitation valve to "Agitation" if necessary.
