HARDI New NAVIGATOR OPERATOR'S MANUAL
ECP & ECPC OPERATING UNIT

Controls adjustment

Before spraying, adjust the ECP or ECPC operating
unit using clean water (without chemicals).
1. Choose the correct nozzle (pp. 24-25). Make sure
that all nozzles are the same type and capacity.
2. Put the tractor in neutral and adjust the P.T.O.
r.p.m. until the number of revolutions of the pump
cor re sponds to the intended traveling speed.
Re mem ber the number of revolutions on the P.T.O.
must be kept between 300-600 r.p.m. (540 r.p.m.
pump) or 650-1100 (1000 r.p.m. pump) to ensure
correct operation of the HARDI-MATIC system.
3. On-off switch (A Fig 17 ) is "ON" against green
symbol (down position).
4. All distribution valve switches (B Fig 17 ) are also
"ON" against green symbol (down position).
5. Hold pressure regulating switch (C Fig 17 ) down
(-) until handle on pressue control valve (4 Fig 19 )
stops rotating. This will be the "minimum pressure"
setting.
6. Hold pressure regulating switch (C Fig 17 ) up
(+) until de sired pressure is shown on the boom
pressure gauge.

Adjustment of constant pressure

Note: Adjust the constant distribution boom pressure
one section at a time as follows: (Start with the
valve turned closed before adjusting).
1. Shut-off the fi rst boom distribution valve switch
(B Fig 17 ).
2. Turn the adjusting screw (1 Fig 18 ) until the pressure
gauge again shows the same pressure as in step
6 (above). (Turn the screw clockwise for higher
pressure, counterclockwise for lower pressure).
3. Turn the fi rst boom distribution valve switch
(B Fig 17 ) back on.
4. Repeat steps 1 through 3 for the remaining boom
section valves.
Note: Hereafter, adjustment of the constant boom
pressure will only be needed if you change to nozzles
with other capacities, but not required if only changing
pressure or application rate using the same nozzles.

Operating the control unit while spraying

In order to shut off the entire boom, fl ip on-off switch
(A Fig 17 ) to the "OFF" (red) symbol (up position). This
returns all the pump outputs to the main tank through
the return system. The diaphragm anti-drip valves
ensure in stan ta neous closing of all nozzles.
In order to shut off one or more sections of the boom,
switch one or more unneeded boom section valves
(B Fig 17 ) to off position. The constant pressure system
ensures that the pres sure does not increase in the
sections which are still open.
