WARNING! When critical chemicals (like sulphonyl urea) have been used or a cleaning adjutant is recommended
do an extra cleaning:
1. Fill the rinse tank again.
2. Fill main tank with 500 l clean water. See subject “External Filling device” for filling procedure.
3. Ad the cleaning chemical to main tank by using the ChemFiller.
4. Clean the whole system again.
5. To get the best cleaning effect the EasyClean and the CycloneFilter sieves should be washed with clean water.
The incorporated rinsing 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 cle-
aning 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 nozz-
les.
2. Turn suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Main tank”.
3. Engage and set the pump at approximately 300 r.p.m.
4. When 1/3 (150 l) of content in rinsing tank are used, turn suction SmartValve towards “Main tank” and operate all valves
on the pressure side of the system in the following order, so all hoses and components are rinsed: Turn the pressure
SmartValve towards “Filling of main tank” to activate ejector and open ChemFiller suction valve, open ChemFiller Vortex
nozzle and close it again when clean water comes out of nozzles. Close ChemFiller lid and squeeze the Chemical
Container Cleaning grip to clean this device. Open ChemFiller lid again and assure that ChemFiller is empty. When empty
then close the ChemFiller suction valve again. Open pressure draining (make sure cap is fitted), Activate agitation and
close it again.
Activate the FlexCapacity System (if fitted).
Take care that the External fast filling connection and the line is not contaminated with chemicals.
5. Turn the suction SmartValve towards “Main tank” and pressure SmartValve towards “Spraying” and spray liquid in the
field you have just sprayed.
Cleaning of Main tank:
6. Turn the suction SmartValve towards “Rinsing tank” and pressure SmartValve towards “Internal Tank Cleaning”. The filling
strainer should be away, so there is no cleaning shadow behind the filling strainer.
7. When another 1/6 of content in rinsing tank are used, then turn suction SmartValve towards “suction from Main tank”.
8. Turn pressure SmartValve towards “Spraying” and spray liquid in the field you have just sprayed.
9. Repeat point 6 - 8 one more time.
