Use Of Flush Tank And Rinsing Nozzles (Optional Equipment) - Hardi NAVIGATOR 3000 Instruction Book

Use of flush tank and rinsing nozzles (optional equipment)

The incorporated flush tank can be used for two different purposes.
A. In-field diluting of remaining spray liquid residue in the spraying circuit for spraying the liquid in the field, before cleaning
the sprayer. This cleaning procedure is divided in three main steps:
Cleaning of the liquid system:
1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all nozzles.
2. Turn suction valve towards "Flush tank" and pressure SmartValve towards "Spray" with control unit turned "Off".
3. Engage and set the pump at approximately 300 r.p.m.
4. When 1/3 of contents in flush tank are used, turn suction valve towards "Main tank" and operate all valves on the
pressure side of the system, so all hoses and components are rinsed. If equipped with HARDI® TurboFiller turn the
pressure SmartValve "Off" (towards unused function) and open TurboFiller suction valve. Open TurboDeflector valve
and close it again when clean water comes out of nozzles. Close TurboFiller lid and squeeze the Chemical Container
Cleaning lever to clean this device. Open TurboFiller lid again and assure that TurboFiller is empty. When empty, close
the TurboFiller suction valve.
5. Turn the suction valve towards "Main tank" and pressure SmartValve towards "Spray". Open the AgitationValve and
spray liquid in the field you have just sprayed.
Cleaning of Main tank:
6. Turn the suction valve towards "Flush tank" and pressure SmartValve towards "Internal Tank Cleaning". The filling
strainer should be removed, so there is no cleaning shadow behind the filling strainer.
7. When another 1/6 of content in flush tank are used, then turn suction valve towards "Suction from Main tank".
8. Turn pressure SmartValve towards "Spray" and spray liquid in the field you have just sprayed.
9. Repeat point 6 - 8 one more time. External cleaning:
10. Turn suction valve towards "Flush tank" and pressure SmartValve towards "Internal Tank Cleaning".
11. When another 1/3 of contents in flush tank are used, turn suction valve towards "Main tank".
12. Turn pressure SmartValve towards "External Cleaning Device" and wash the sprayer with the cleaning device located
on sprayer's right side.
13. Disengage pump again.

WARNING! When critical chemicals (like sulphonyl urea) have been used or a cleaning adjutant is recommended do
an extra cleaning:
1. Fill the flush tank again.
2. Fill main tank with 130 gal. (500 liters) clean water. See subject "Filling of water" for filling procedure.
3. Add the cleaning chemical to main tank by using the TurboFiller.
4. Clean the whole system again.
5. To get the best cleaning effect, the filter meshes for the EasyClean and the CycloneFilter should be washed with clean
water.
