Tank Filling
When filling the sprayer it is necessary to connect to
an external water source.
The main tank should be filled through the 3" fill
point mounted to the side of the EZ control station
on the left hand side of the sprayer. This line fills
through the top of the tank and then through a hose
inside the tank so that the water is deposited in the
centre of the tank. Water can then be pumped into
the system from an external pump. Filling progress
can be monitored via an optional fill flow meter (see
Chapter 12 'Optional Accessories').
WARNING: Water weighs 1 kg per litre. Conversion
factors must be used when spraying liquids that are
heavier than water. The total weight of the liquid
being sprayed should not exceed the equivalent
weight of a full tank of water. Exceeding this weight,
can lead to sprayer damage.
For example: Liquid nitrogen has a density of 1.28 kg
per litre. If the tank size is 2000 L, then:
2000 L / 1.28 kg = 1563 L
This means that the total volume of liquid Nitrogen
allowed in a 2000 L tank is 1563 L.
This rule applies for all tanks sizes. If unsure about
the density/weight of the chemicals being applied,
contact your agronomist or chemical supplier.
MAIN TANK FILL PROCEDURE
1. Connect the fill hose (not supplied) to the 3" fill
cam lock coupling which is mounted to the EZ
control station on the left of the sprayer.
2. Make sure that the main tank fill handle on the
EZ control is in the OFF position (so that there
can be no flow coming out of the tank if it is not
already empty).
3. Turn the fresh water pumping system on (make
sure the pressure does not exceed 75 PSI).
4. Turn the EZ control main tank fill handle ON. The
main tank should now be filling.
5. When the required amount of water has been
transferred into the main tank, stop the flow by
turning the main tank fill to OFF.

EZ Control External Water
Delivery Station
The external water delivery station allows several
filling functions of the sprayer to be performed
simultaneously.
1. With fresh water coming into the system as per
"Main tank fill" instructions, ensure that all flip
valves, including the "main tank fill" ball valve, on
the external water delivery station are turned to
OFF.
2. Turn the desired function ON by selecting the
appropriate flip valve as labelled.
3. When filling the foam marker tank, ensure that
the foam marker tank is vented.
4. When the required amount of water has been
transferred, turn the appropriate flip valve to OFF.
5. When all functions have been performed, turn the
external water delivery system OFF.
Rinse Water Tank Fill
The rinse water tank holds approximately 45 litres.
Make sure this tank always has sufficient water in it
in case a chemical accident occurs and rinse water
is needed to wash chemical from any contaminated
persons, clothing or components.
RINSE TANK FILL PROCEDURE
1. Start by ensuring that all ball valves on the fill
station are turned off.
2. Lift the 'Rinse tank fill' red handle on the EZ
control 3-way ball valve to the vertical position.
This is the ON position.
3. Connect the fresh water fill hose to the to the 3"
fill cam lock coupling.
4. Operate the fresh water pumping system (make
sure pressure does not exceed 75 PSI). There
should now be flow transferring to the rinse
water tank.
5. When the required amount of water has been
transferred to the rinse water tank, stop the flow
by turning off the external water supply and shut
the rinse water tank fill valve by flipping it back
down.
