Cleaning and maintenance of filters
Clean filters ensure:
•
Sprayer components such as valves, diaphragms and operating unit are not hindered or damaged during operation.
•
Nozzle blockades do not occur whilst spraying.
•
Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer
components is the suction filter. Check it regularly.
Use of rinsing tank and rinsing nozzles (optional)
The incorporated rinsing tank can be used for two different purposes.
μ
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
In-field diluting before cleaning
In-field diluting of remaining spray liquid residue in the spraying circuit, before cleaning the sprayer.
Rinsing the main tank and 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 and pressure valve towards .
3.
Engage and set the pump at approximately 300 r.p.m.
4.
When 1/3 of the contents in the rinsing tank is used, turn suction valve towards and operate all valves on the
pressure side of the system in the following order so that all hoses and components are rinsed:
•
Turn the pressure valve towards ”Filling of main tank” to activate ejector 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 grip to clean this device.
•
Open TurboFiller lid again and make sure that TurboFiller is empty.
•
When empty, close the TurboFiller suction valve again. Take care that the External fast filling connection and the line
are not contaminated with chemicals.
5.
Turn the suction valve towards and the pressure valve towards and spray the liquid in the field just sprayed.
Cleaning of Main tank:
6.
Turn the suction valve towards and the pressure valve towards . Remove the filling strainer to avoid any
cleaning shadows behind it.
7.
When another 1/6 of the contents in the rinsing tank is used, turn the suction valve towards .
8.
Turn pressure valve towards and spray the liquid in the field just sprayed.
9.
Repeat point 6 - 8 one more times.
±
WARNING! When critical chemicals (like sulphonyl urea) have been used or a cleaning detergent is recommended, do
an extra cleaning:
10.
Fill the rinse tank again.
11.
Fill the main tank with 500 l clean water. See subject “External Filling device” for filling procedure.
12.
Add the cleaning detergent to the main tank by using the TurboFiller. Follow instructions on the label of the cleaning
agent.
13.
Clean the whole system again.
14.
To get the best cleaning effect the Self-Cleaning Filter and the Suction Filter sieves should be washed with clean water.
15.
Rinse the sprayer with clean water afterwards.
μ
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 to be sprayed afterwards!
