5 - Operation5.6Filling of clean water tankA clean water tank is integrated into the front left corner of the main tank(behind the MANIFOLD system). It is accessed for filling at the sprayer’sleft side when entering the platform. Remove tank lid, fill with cleanwater and replace tank lid.For use of water, turn the ball valve lever to open tap. The ball valve islocated at the bottom of the clean water tank on sprayer’s left side. Thewater from this tank is for hand washing, cleaning of clogged nozzles,etc. Only fill the clean water tank with clean water.Capacity: 4.8 gal. (18 liters).± WARNING! Although the clean water tank is only filled with clean water, this water must never be used for drinking.Adjustment of EVC operating unitBefore spraying, adjust the EVC operating unit using clean water(without chemicals).1. Choose the correct nozzle for the spray job by turning the TRIPLETnozzle bodies. Make sure that all nozzles are the same type andcapacity. See the “Spray Technique” book.2. Make sure all distribution valves (A) are turned on.3. Set pressure regulation valve to minimum pressure (activatepressure regulation switch “down” until emergency handle stopsrotating).4. Put the tractor in neutral and adjust the P.T.O. revolutions to thenumber of revolutions that will typically be used while spraying. Remember the number of revolutions on the P.T.O.must be kept between 300-600 r.p.m. (540 r.p.m. pump) or 650-1100 rpm (1000 r.p.m. pump).5. Activate pressure regulation switch “up” until the required spraying pressure is shown on the pressure gauge.Adjustment of pressure equalization:1. Disconnect power to the control box to allow for manual operation of the boom distribution valves. Adjustments willbe made one section at a time until all valves have been adjusted.2. Note the pressure on the pressure gauge. This reading will be used throughout the adjustment.3. Manually close one of the distribution valves by turning the green handle (A).4. Turn the adjusting screw (B), under the valve just closed, until the pressure gauge again shows the same pressure asbefore (clockwise for higher pressure, counterclockwise for lower pressure).5. Turn the distribution valve (A) back on.6. Adjust the other sections of the distribution valve in the same way. ATTENTION! HEREAFTER ADJUSTMENT OF PRESSURE EQUALIZATION WILL ONLY BE NEEDED WHEN:1. YOU CHANGE TO NOZZLES WITH OTHER CAPACITIES2. THE NOZZLE OUTPUT INCREASES AS THE NOZZLES WEAR
