Don’t use the sprayer without having consulted the enclosed handbook.

Before removing the cover of the filter, make sure that the same is isolated from the tubing by unscrewing the relevant rear valve (FIG. N°8) or on the 3- way deviator (FIG. N° 10, page 14).

After washing the cartridge, reassemble the cover making sure you connect the same to the circuit again, using the valves described above in the opposite order.

WARNING!: Don’t disperse the washing residues in the environment!!

4.8PRESSURE REGULATOR

To use the pressure regulator, follow the instructions in the enclosed handbook scrupulously. The pressure regulator controls all of the most important spraying functions, the thorough knowledge of its functions makes work easier and more precise.

The working pressure and the maximum pressure of the sprayer are determined by the pressure regulator which also protects the circuit from overpressure in any work conditions. (In serious but very rare cases, if the connecting pipes get blocked the pressure relief valve lets the pressure off)

In some setups there may be a pump that can reach a pressure of 50 bar controlled by a regulator designed for 20 bar. In this case the maximum pressure that can be reached is 20 bar.

The regulators can be manual, mounted on the sprayer or at a distance to make the controls easier to use; or electrical with a control panel in the cabin. There are also regulator versions with mechanical remote controls with a cable. If the tractor has a waterproof cabin the use of electrical controls is obligatory.

4.8.1 COMPONENTS OF THE PRESSURE REGULATOR

Below you will find the indications for the main models fitted on Unigreen products.

A main ON-OFF command: “open” lets the fluid flow into the circuit in use; “closed” empties the tank.

B maximum pressure valve: adjusted by hand with the relevant knob (drains the excess liquid when the set pressure is reached).

C jets section tap: opens the corresponding jet boom or drains to the compensation regulator (G).

D auxiliary tap: can be used for various accessories (it is always manual). E volumetric pressure valve (proportional):

(when present) it regulates the spraying pressure. The valve automatically compensates variations in speed (within the scope of the same gear ratio), keeping the quantity of liquid supplied per surface unit (litres/hectare) unchanged.

Fself-cleaning filter: filters the delivery liquid.

G compensation regulators: suitably regulated, these make it possible to keep the pressure constant when one or more sections of jets is closed, they don’t influence treatments with the boom fully open.

H manometer: indicates the working pressure.

Connections:

R1 supply union

R2 drain union

R3 volumetric drain union

R4 jets section delivery union

R5 auxiliary delivery union

Control box for GCP ELETTRICO electrical regulators

I1 main control valve switch

I2 volumetric pressure valve switch (proportional)

I3 jets section valves switches

4.8.2 GENERAL INSTRUCTIONS

When using the pressure regulator, scrupulously observe the instructions in the enclosed handbook, below you will find generic indications for the major models fitted by Unigreen.

All the regulation and adjustment tests must be carried out with clean water.
