  • Page 26: Hydro-Pneumatic System

    The hydro-pneumatic system is medium to high pressure. This system takes advantage of the great amount of turbu- lence in the cone-shaped, low-volume nozzle and distributes the sprayed mist correctly. The air enters the spout at high speed and spreads the mist in the shape of a fan. The ZENIT sprayer uses spouts with three nozzles. 3.12...

  • Page 27: Sprayer Setup

    4 - Sprayer setup General info Unloading the sprayer from the truck When unloading with an overhead lifting device, please observe the lifting points as shown in the picture, and make sure that the straps or belts used for lifting are strong enough. If using a forklift, be careful not to damage the fittings at the bottom of the tank.

  • Page 28: Mechanical Connections

    4 - Sprayer setup Mechanical connections Transmission shaft - Installation First installation of the transmission shaft is done in the following way: 1. Attach sprayer to tractor and set sprayer height in the position with shortest distance between the tractor and sprayer pump P.T.O. shafts.

  • Page 29: Hydraulic Systems

    4 - Sprayer setup Hydraulic systems General info Ensure that snap couplers are clean before connection! After having operated the hydraulics and the system has been filled with oil, check tractor’s hydraulic oil level and top up if necessary. DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which can cause violent movements of the CANNON spout (optional).

  • Page 30: Air Systems

    4 - Sprayer setup Air systems Adjusting the fan (axial system only) The angle of the fan blades can be adjusted to 4 positions. They are normally factory set to position 3. Decreasing the angle of the blades (minimum angle, position 1) lessens the flow and decreases power consumption.

  • Page 31: Booms

    Technical information The ZENIT sprayer equipped with a pneumatic blower unit can be attached to the B-11 fixed boom. This boom can be adapted to several different spout combinations, depending on whether it is a pneumatic or hydro-pneumatic air system.

  • Page 37: Diaphragm Pump

    Pressure damper adjustment The air pressure in the damper on the HARDI® diaphragm pump is factory preset at 30 psi (2 bar). This is suitable for nozzle spray pres- sures between 45 and 220 psi (3 and 15 bar). If different nozzle pres- sures are required, set pressure damper at pressures indicated.

  • Page 38: Nozzles

    5 - Operation Nozzles The standard nozzle holders included in axial air kits are made of brass (A). They can be closed individually by turning them 90°. When open, they have a range of +/- 15° to vary their inclination. They are fitted with a non-drip valve (B) to avoid the loss of chemical product that remains in the lines when the different sections are shut off.

  • Page 39: Hc1/ Or Hc/2 Control

    5 - Operation HC/1 or HC/2 Control After filling the tank with clean water, locate your sprayer in a suit- able location to spray water from the nozzles. Before starting the pump, make sure the pressure regulator valve (B) is turned all the way out (counter clockwise).

  • Page 40: Bk/2 Manual Control

    Before starting the pump, turn the main On/Off valve (A) to the “On” position (“Up” as shown) and turn the HARDI-MATIC valve (C) count- er clockwise all the way out. Open or close levers (F) depending on whether pressure agitation and/or the powder mixer is required.
