4.12.3 PREMIXER ON HOPPER WITH TIN WASHER (OPTIONAL)
Campo 22-32 machines come equipped with the TOP-MIX S-41 premixer
(FIG. No. 10); this version of the premixer allows independent adjustment of
pressure knob, avoiding having to change the work settings of the machine
every time you have to do the premixing.
To mix the product in the tank proceed as follows:
= turn the lever of the delivery deviator to the TOP-MIX position as shown in
the pictogram on the machine.
= adjust Top-Mix pressure to approximately 10-12 bar by turning control M
(the manometer allows you to check the actual pressure)
= press lever 4 for a few seconds introducing 3-4 litres of water into the
hopper.
= open the premix, overturning the cover as shown in the photo and introdu-
ce the product to mix into the hopper 1, close the cover again.
= press lever 4 to mix the product in the hopper, watching the level of the
liquid which could overflow. To prevent overflowing and to help powder
products dissolve, open tap 6) to drain into the tank.
= after emptying, close tap 6.
To wash the tin, proceed as follows:
= open the premix, overturning the cover as shown in the photo
= supply the premix using the control to regulate a pressure to under 3-4
bar
= introduce the tin into the hopper, insert washing pipe 2 into the tin, press
the tin onto the pipe until it has been completely washed.
= open tap 6 to drain into the tank at the same time.
= after emptying, close tap 6.
NB: If the tin washer isn’t supplied with clean water and isn’t fitted with the
optional electrical pump, you must rinse again by hand with clean water.
THE LIQUIDS USED FOR RINSING SHOULD BE
INTRODUCED INTO THE TANK AND BE SPRAYED ON
THE FIELD.
At the end of the operations, wash the hopper:
= check that the cover and all the taps of the premix are
closed and open the supply tap on the sprayer, delivering
liquid at a pressure of roughly 10-12 bar (never exceed 15
bar).
= open safety tap 10.
= press lever 4 to activate jets 3 and 9, watching the
level of the liquid which could overflow. To prevent
overflowing, open tap 6) to drain into the tank.
= after washing, release lever 4 and close taps 6 and 10.
NB: At the end of all of the operations put the lever of
the deviator back into the work position.
