Using The Drain Valve - Hardi NAVIGATOR 3000 Instruction Book

5 - Operation
B. Flushing the pump, operating unit, spray lines, etc. in case of interruption in spraying before main tank is empty (e.g.
beginning rain etc.).
Cleaning of the liquid system:
1. Turn suction valve towards "Flush tank". (Keep pressure SmartValve in "Spray" position).
2. Close AgitationValve (no agitation) and turn CycloneFilter return valve to position A (marked with 1 dot) to prevent
return flow from diluting main tank contents.
3. Engage the pump and spray water from flush tank in the field until all nozzle tubes/nozzles are flushed with clean
water.
4. Disengage pump again.
ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually with a
brush afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed afterwards!
ATTENTION! It is advisable to increase the forward speed (double if possible) and reduce the pressure to 20 psi (1.5
bar) when spraying diluted remaining liquid in the field 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.

Using the drain valve

The drain valve is located and operated from the platform just beside
the main tank lid. Pull the string to open the drain valve. The valve is
spring-loaded, but can be kept open by pulling the string upwards in
the V-shaped slit. To release, pull the string downward and the valve will
close automatically.
If draining residues, e.g. liquid fertilizer into a reservoir, a snap-coupler
with hose can rapidly be connected to the drain valve and the liquid
safely drained.
