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.

Pressure regulators without a volumetric valve (GCP3-way - RPN - RVA)

Adjusting the maximum pressure valve

=put main control A in the drain position (“OFF”).

=loosen the hand wheel of maximum pressure valve B completely (anticlockwise).

=start the pump by activating the power-takeoff of the tractor at 540rpm

=open main control A (position “ON”), the manometer will be activated

=open all of the section valves C (position “ON”)

=adjust maximum pressure valve B to the working value (in any case less than the safe maximum pressure the system can reach).

Pressure regulators with a volumetric valve (RPN-DPR-ERGO-REMO) Adjusting the maximum pressure valve

=put main control A in the drain position (“OFF”).

=loosen the hand wheel of maximum pressure valve B completely (anticlockwise).

=open volumetric valve E completely.

=start the pump by activating the power-takeoff of the tractor at 540rpm

=open main control A (position “ON”), the manometer will be activated

=open the drain tap on filter F slightly (only ERGO and REMO)..

=close volumetric valve E completely. If the pressure rises over the maximum limit of the system, make sure maximum pressure valve B is open (see previous indications)

=open all of the section valves C (position “ON”)

=adjust maximum pressure valve B to a value over that of the working pressure (generally 10-14 bar) and in any case lower than the safe maximum pressure that the system can reach.

Adjusting the volumetric pressure.

=with the volumetric pressure valve E adjust the pressure to the value the treatment will be done at (the pressure is indicated on the nozzles tables on the basis of the tractor speed and litres/hectare to spray)

Warning! The working pressure must be adjusted with the volumetric valve and not with the maximum pressure valve. In the case the working pressure is too near to the calibrated pressure of the maximum pressure valve, the proportional valve may not be able to compensate the speed variations correctly.

Adjusting the compensated returns

=close only one tap of section C (position “OFF”).

=adjust the corresponding compensator G until you return to the pressure set previously (displayed on the manometer).

=open and close the tap of section C and check that the pressure remains constant.

=repeat the above operations for all the section taps.

If the types of nozzles aren’t changed the regulations carried out will guarantee a constant spraying of the liquid also per treatments that are done at different working pressures.

NB: if the type of nozzle is changed then the calibrating will have to be done again.

4.9DELIVERY FILTERS (ONLY EQUIPPED MODELS) Particularly useful when using small (low volume) nozzles.

In a central position with a manometer after the filter that shows any blockages in the cartridge. On the RVA version there is also a manometer before the cartridge to make it easier to find the problem.

For cleaning the cartridge in the model RVA you should open the drain with the relevant lever (Fig. N° 4) for 2-3 minutes during the washing operations, as in the enclosed instructions.

You should clean the cartridge by hand periodically, on the basis of the product used. To clean, stop the pump. Wear rubber gloves and the other personal

protective equipment when cleaning.
