4.10 FILLING THE TANK
The machines for defensive crop treatments, in consideration of the safety of
persons, animals and the protection of the environment, must only be filled
indirectly from open water courses and only by free-falling water from the
waterworks.
The pipe used for filling must never come into contact with the liquid inside the
tank and therefore the water must always fall over the upper edge of the filling
inlet and through the filter installed on it.
The tank is fitted with a transparent graduated band that shows the exact
quantity of liquid inside. This reading is precise if the tank is on flat ground; the
actual total capacity coincides with the highest number. All the filling systems
fitted by Unigreen on their production machines or on request are antipollution
and stop the liquid overflowing out of the tank.
a)
FILLING WITH THE SUCTION FILTER (Fig. 10 - Fig. 11).
If the 3-way deviator isn’t fitted you can fill the tank using the coupling on the
cover of the suction filter. Unscrew the rear wing nut of the filter and using a
G1"1/2 threaded union, connect pipe
T
with the floating filter to the coupling.
Also in this case the filling speed in litres/minute is equal to the delivery of the
pump.
b)
FILLING WITH THE ANTIPOLLUTION EJECTOR (Fig. 12)
If you are filling with an antipollution hydroejector (mounted as standard on
some models) then you should proceed as follows:
=
put roughly 20-30 L of water in the tank and start the pump.
=
remove the cap of ejector
E
and insert filling pipe
T
.
=
place the other end of the hose, on which you fitted filter
G
, in the watering
point.
=
open the tap that supplies the ejector (on pump
P
or pressure regulator
C
).
=
increase the pressure until it reaches a value which is sufficient to suck up
the liquid.
=
visually check the level of the liquid inside the tank and after filling
disconnect pipe
T
from the ejector, close the tap and replace the cap.
4.11 TEST WITH CLEAN WATER
It is good practice to do a test with clean water (without chemical product in the
tank) before the first treatment to make sure the atomiser is working properly
and to get to know the controls. For instructions on how to proceed with the
treatment see the chapter SPRAYING.
4.12 MIXING
The active principle can be mixed using the relevant stirrers before and during
the treatment. Correct mixing and stirring is the basis of the correct distribution
on the crops. We recommend some useful accessories such as the premixer
for powders and liquids (see the following paragraph).
To mix the product in the tank proceed as follows:

WARNING: using the taps on the
pump or in any case on the front of
the machine puts the operator near
the cardan shaft. Despite the
presence of protections at CE rule, it
is compulsory to switch off the engine
and to take the key off.
