10.0 WASHING THE TANKS AND THE
SYSTEM
ATTENTION
After each treatment, wash the outside of the whole
machine, the inside of the tank and the whole circuit,
in order to limit chemical aggressiveness. Persistence
of products on the surfaces of materials may cause
damage.
Moreover, complete elimination of crop protection
product residues correctly prepares the machine for
the next utilisation even with a different formulation.
ATTENTION
In case of using liquid fertilisers or particularly ag-
gressive products, protect the machine with suitable
products and wash with care after each use.
10.1 TECHNICAL RESIDUE AND NEED TO
WASH THE MACHINE
it is unavoidable for some liquid to remain in the tank and
in the suction and delivery circuit.
The technical residue corresponds to the amount of liquid
remaining in the circuit when pressure instability occurs,
due to air suction from the emptying tank.
The technical residue consists of two parts:
a)
Dilutable residue
: amount of mixture contained in the ma-
chine's circuit before the main valve (including main tank.)
b)
Non-dilutable residue
: Amount of mixture contained
in the machine circuit after the general valve and in the
supply valves.
Both must be disposed of on a portion of ground conveni-
ently not previously treated or in any case suitable to
disposing of a diluted mixture.
10.2 CIRCUIT WASHER AND TANK
WASHER
The machines for treatment are fitted with circuit washer
tank. This tank must be filled with clean water and has the
purpose of rinsing the main tank, the whole suction, deliv-
ery circuit, pump, pressure regulator, nozzles and holders
and also the whole inner surface of the tank thanks to the
convenient rotating nozzle.
ATTENTION
To completely clean the tank and the ducting from the
residues of the various active principles, it is recom-
mended to add 2kg of soda every 100 l of washing
water.
After finishing the treatment, wash the circuit and the drum.
• Stop the membrane pump by disengaging the PTO.
• Check that the circuit washing tank is full.
• Make sure the main control of the pressure regulator is
in the OFF position and that all bar sectors are closed.
• Rotate the suction diverter (2) in H2O circuit washer
position.
• Activate the membrane pump by engaging the PTO.
• Increase the rpm speed until draining all liquid inside
the circuit washing tank.
• Turn off the membrane pump and rotate the diverter
in work position (TANK).
• Place the main control in ON position, to pressurise
the circuit.
• Reactivate the membrane pump and operate the
drum washing circuit on the regulator (or on the
pump) which powers the nozzle.
• After a few minutes, he drum washing cock can be
closed.
•
Distribute the washing residue in a portion of the field
where it does not cause damage.
•
After washing is finished, stop the membrane pump.
NB: upon completing washing, if the period is at risk of
freezing, insert in the tank about 500 grams of normal car
anti-freeze.
ATTENTION
Using cocks on the pump or at the front of the ma-
chine places the operator near the PTO shaft. Despite
the presence of CE compliant guards, it is required to
turn off the tractor’s engine and remove the key from
ignition.
