Cleaning The Tank And Liquid System; Use Of Rinsing Tank And Rinsing Nozzles (Optional) - Hardi NEPTUN Series Instruction Book

Cleaning the tank and liquid system

1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the crop/orchard
just sprayed.
2. Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivating
agents if necessary.
3. Rinse and clean mistblower and tractor externally. Use detergent if necessary.
4. Remove tank and suction fi lters and clean. Be careful not to damage the mesh. Replace suction fi lter top. Replace
fi lters when the sprayer is completely clean.
5. With the pump running, rinse the inside of the tank. Don't forget the tank roof. Rinse and operate all components
and any equipment that have been in contact with the chemical. Before opening the distribution valves and
spraying the liquid out, decide whether this should be done in the fi eld again or on the soakaway.
6. After spraying the liquid out, stop the pump and fi ll at least 1/5 of the tank with clean water. Note that some
chemicals require the tank to be completely fi lled. Add appropriate detergent and/or deactivating agent, e.g.
washing soda or Triple ammonia.
7. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Leave
the distribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short
period. Check the label.
8. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry.
9. Stop the pump. If the pesticides used have a tendency to block nozzles and fi lters, remove and clean them
immediately.
10. Replace all the fi lters and nozzles and store the mistblower. If, from previous experiences, it is noted that the solvents
in the pesticide are particularly aggressive, store the sprayer with the tank lid open.
ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the pressure to 1.5 bar (20
psi) when spraying diluted remaining liquid in the fi eld just sprayed.
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended.

Use of rinsing tank and rinsing nozzles (optional)

The incorporated rinsing tank can be used for two diff erent purposes.
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.

nozzles.
2. Turn suction valve towards "Rinsing tank" and pressure valve towards "Spraying".
3. Engage and set the pump at approximately 300 r.p.m.
