Evc Control Unit (Std); Efc Control Unit (Df4) - Hardi NAVIGATOR 3000 Operator's Manual

Suction SmartValve (Blue symbols)
This valve selects suction from main tank or from the rinse tank.
The handle is turned so the label for required function is directed to the
indicator. If the handle is turned to a position without label (unused
function), the valve is closed.
Main tank
Main Tank Quick fill Valve (Blue symbol)
This valve opens and closes the main tank quick fill hose.
The open function is activated when the handle is turned up to point to
the indicator. If the handle is turned horizontal or down, the valve is
closed.
Main tank Quick fill
Agitation Valve (Green symbol)
With the adjustable agitation valve, it is possible to combine spraying
with a high volume rate at high pressure with agitation at the same time.
This is controlled continuously by the valve: The valve is marked with an
arrow on the disc that indicates the amount of liquid that passes
through the valve.
• If the handle is turned to a position near the tip of the arrow, then
only a small amount of liquid is allowed to pass the valve, resulting
in less agitation.
• If the handle is turned to a position in the wide end of the arrow, then a large amount of liquid will pass the valve,
resulting in more agitation.

EVC Control Unit (Std)

Sprayers equipped with the EVC control unit (Electrical Valve Control) are equipped with a pressure regulation valve at the
front of the sprayer and ON/OFF boom section valves at the rear of the sprayer. The unit has a built-in mechanical rate
controller (HARDI-MATIC) and each boom section valve has manual pressure equalization to maintain constant pressure
when one or more sections are turned ON/OFF.
HARDI-MATIC is a mechanical rate controller that ensures a constant volume of spray solution per acre even at varying
speeds within the same gear. Maximum performance is obtained with a P.T.O. shaft speed between 300-600 r.p.m. (540 r.p.m.
pump) or 650-1100 r.p.m. (1000 r.p.m. pump).

EFC Control Unit (DF4)

Sprayers equipped with the EFC control unit (Electric Fluid Control) are equipped with a DF4 (DynamicFluid4) pressure
regulation system. This includes a DF4 pressure regulation valve at the front of the sprayer, ON/OFF boom section valves at
the rear of the sprayer and multiple sensors (speed, flow, pressure, pump r.p.m. and DF4 valve angle).
