1 IMPORTANT! Turn the EC operating unit off.
2 Partially fill Main Tank, then fill FlushTank (P 12-13).
3 Turn the pressure valve (B Fig 32) to align with the
icon indicating the CHEM FILL.
4 Align Suction valve (A Fig 32) with FLUSH TANK.
This means that, as the Flush Tank is being topped
up from your water supply, its contents will be used
to mix with chemical concentrate in the Granni Pot,
the mixture then transferring to the Main Tank.
5 Follow GRANNI POT Operators Manual directions.
NOTE! Watch level of fluid in Flush Tank. Keep fluid
level consistent by adjusting theFILL handle (E Fig
32) between FLUSH TANK and OFF.
6 After adding chemicals, with the Suction valve (A
Fig 32) remaining at FLUSH TANK, flush the
GRANNI POT with clean water.
7 Turn Pressure valve (B Fig 32) to DISTRIBUTION
(spray), and return Suction valve (A) to MAIN TANK.
Open primary filling valve to MAIN TANK to complete
filling.
Re-fit camlock plug to fill filter when all filling is completed.
C) Adding Chemicals at the Same Time as
Filling the Main Tank via the Flush Tank:
WARNING! This method requires you to be
constantly alert!
You need to carefully watch and control fluid
levels in the Flush tank while operating the
GRANNI POT as there is increased risk of
contamination, overfilling and accidental
spillage.
B) Adding Chemicals After Filling Tanks:
1 IMPORTANT! Turn the EC operating unit off.
2 Fill all tanks as described, allowing space in the main
tank for the addition of chemical / water mixture
(Filling P 12-13).
Turn FILL handle (E Fig 32) OFF.
3 Align Pressure valve (B Fig 32) with the icon indicat-
ing the CHEM FILL.
WARNING! This method may result in over-
filling, leading to spillage and contamination;
or over-diluting spray solution in the Main
Tank, reducing its efficacy.
4 Turn the Suction valve (A Fig 32) to MAIN TANK.
This means liquid from the MainTank will be used to
mix with chemical concentrate in the Granni Pot.
Follow GRANNI POT Operators Manual directions.
5 After adding chemicals, flush the hopper with clean
water (Suction valve (A Fig 32) to FLUSH TANK.
6 Return Suction valve (A) to MAIN TANK, and
Pressure valve (B) to DISTRIBUTION (Spray).
Re-fit camlock plug to fill filter when all filling is completed.
Adding Chemicals with HARDI Granni
Pot
TM
and Manifold Valves.
There are three methods described below for adding
crop protection chemicals to the main tank of your
sprayer using these new Hardi features.
NOTE: It is recommended to use the first of
the following three methods to add chemicals
to your sprayer main tank. It is the simplest and
safest method.
By using this method, your full attention can be directed
at the potentially hazardous chemicals you are handling
during operation of the Granni Pot chemical filler.
Note: This method minimises the risk of overfilling the
tanks or overdiluting the spray solution.
A) Adding Chemicals to a Partially-Filled Main Tank:
1 IMPORTANT! Ensure the EC operating unit is off.
2 Fill the Flush Tank, then fill the Main Tank to around
25% of required spray volume (unless otherwise
stated on chemical container label).( Filling, P12-13).
3 With FILL handle (E Fig 32) OFF, align the Pressure
handle (B Fig 32) with the icon indicating CHEM FILL.
4 Align Suction valve (A Fig 32) with MAIN TANK. This
means liquid from the Main Tank will be used to mix
with chemical concentrate in the GRANNI POT, and
the spray solution will be used to flush the concen-
trate from the GRANNI POT hopper.
5 Follow GRANNI POT Operators Manual directions.
6 After adding the required chemicals, you can flush
the GRANNI POT hopper with clean water. Align the
Suction handle (A Fig 32) to FLUSH TANK.
7 IMPORTANT! Return the Suction handle (A) to MAIN
TANK, and Pressure (B) to DISTRIBUTION (Spray).
Continue filling the Main Tank with tractor running.
Re-fit camlock plug to fill filter when all filling is completed.
CAUTION! To prevent backflow and contamination ALWAYS return valves to OFF / quadrant position after use.
