Assembly Instructions
To assemble the CropPak sprayer:
1 Unpack the unit and check that nothing is missing
or has been damaged in transit.
2 Connect the lance to the hand grip and tighten
the flange.
3 Check all worm-drive clips for tightness (if
applicable).
4 Check and clean (if necessary) the suction filter:
• On UM70 models - Unscrew the filter, remove
and clean. Refit the filter & suction line and
tighten.
• All other models - Unscrew the suction filter
cap, remove and clean the filter screen. Refit
the screen & filter and re-tighten.
5 Check that the pressure line hose is connected.
6 Check the tank drain plug is fitted and sealed.
Unpack the sprayer.
Remove and clean suction filter (UM70 only).
Check & clean the suction filter.
Check the tank drain plug is sealed.
Whilst all precautions are taken in assembly
and testing, it is possible that some tank
filings remain in the lines. These will
accumulate in the suction filter when first
used. Therefore, clean the filter out after
initial use, and nozzles, if necessary.
NOTE
Refit the filter & suction line (UM70 only).

CropPak Assembly
Connect the power leads to a 12 Volt battery. Connect the power lead to the pump.
Battery Connection
The Flojet pump must be connected directly to the +ive
and -ive terminals of a 12 Volt battery.
To Connect the CropPak sprayer to a 12 Volt battery:
1 Unpack the wiring loom (UP-119B).
2 Connect the power leads to a 12 Volt battery:
• The red (+ive) power lead to the positive
(+ive) battery terminal, and
• The black (-ive) power lead to the negative
(-ive) battery terminal.
The leads must be connected to a 12 Volt battery.
Failure to connect leads to a battery of the correct
voltage will cause damage to the electric motor.
3 Connect the power lead to the pump.
Fitting the CropPak to a Carrier
The free-standing design of the CropPak units allows
them to be used on many types of vehicles.
When using a CropPak on a vehicle, always strictly
adhere to the vehicle manufacturer’s load carrying
specifications.
To fit the CropPak onto a vehicle:
1 Place the CropPak onto the vehicle. If a stand
alone battery is being used, fit this also.
The leads must be connected to a 12
Volt battery. Failure to connect leads to a
battery of the correct voltage will cause
damage to the electric motor.
CAUTION
When using a sprayer on a vehicle, always
adhere to the vehicle manufacturer’s load
carrying specifications. Failure to do
this could result in serious damage and
injury

2 Secure the CropPak (and battery, if applicable) so
that they are not able to slide around or tip over
when the vehicle is moving.
Optional straps are available. The UM70 comes
supplied with a 4 metre strap.
3 Connect the CropPak power leads to the battery
terminals (on vehicle or stand alone) [see battery
connection instructions on the previous page].
To remove the CropPak from a vehicle:
1 Disconnect the CropPak wires from the battery
terminals.
2 If fastened, unfasten the CropPak (and battery, if
applicable) from the vehicle.
CropPak Assembly
3 Remove the CropPak from the vehicle and store
them in a suitable location, preferably under-
cover - protected from the sun and the weather.
If the CropPack is fitted to any ATV, two or
four wheel motorcycle, the CropPak MUST
BE secured with suitable self-locking carry
straps.
WARNING
The leads must be connected to a 12
Volt battery. Failure to connect leads to a
battery of the correct voltage will cause
damage to the electric motor.
CAUTION
Whilst all precautions are taken in assembly
and testing, it is possible that some tank
filings remain in the lines. These will
accumulate in the suction filter when first
used. Therefore, clean the filter out after
initial use, and nozzles, if necessary.

Calibration Chapter 3
Calibration 18

18
Calibration
GP-OMCP12-B
Sprayer calibration is one of the single most important
factors in establishing the correct application rate of
the sprayer.
Without calibration it is not possible to know the actual
rate of spray application.
Calibration
Today, we must strive for the most efficient use of spray
chemicals for effective pest and disease control.
Increasing costs, as well as consumer and public
pressures to minimise residues, requires us to achieve
the target application rate (uniform spray coverage
without over or under spraying).
Applying the correct amount of chemical to a crop is
only possible if the:
• Sprayer is calibrated correctly (this chapter).
• Sprayer is operated correctly (see chapter 4).
• Sprayer is maintained correctly (see chapter 5).
Correct chemical application rate can only be achieved
if the variables of spray application are measured and
controlled:
• Distance, time & working width are measured.
• Liquid & chemical volume applied.
This is done through sprayer calibration.
Spot Sprayer Calibration
Do not operate a sprayer without
calibration or before calibration has been
completed.
Failure to calibrate a sprayer before
operating may result in ineffective or crop
damaging spray application.
CAUTION

19
Chapter 3
GP-OMCP12-B
Spot Sprayer Calibration
CropPack sprayers are most commonly used for spot
spraying using a hand gun with a single variable cone
or flat fan nozzle.
Precise application rates are not usually achieved with
hand guns because the application rate is entirely
dependent on the operator.
Two steps are recommended for calibrating a spot
sprayer:
1 Choose the appropriate nozzle.
2 Check the nozzle operates correctly.
Step 1
Choose the Appropriate Nozzle
The nozzle used should be appropriate for the chemical
being used. The standard adjustable ConeJet should
suffice for general Glyphosate-based formulations
& applications. Follow the chemical manufacturer’s
recommendation for any specific nozzle requirements
as per the manufacturers label.
The standard CropPak lance has a removable cap,
the adjustable ConeJet can be removed and most 80
and 110 degree flat fan nozzles can then be used with
the cap & seal.
Pump Specification
The nozzle chosen must be within the flow capability
of the pump on your CropPak.
CropPack sprayers are fitted with pumps that operate
within a pressure range.The pump model FL3501-506
is a Triplex diaphragm pump with an internal bypass
which allows the pump to work with a nozzle within a
range of flow from approximately 1 litre per minute to
2.5 litres per minute in the correct pressure range for
the pump.
The FL3501 Series pump is fitted with an inbuilt
automatic shut off pressure switch which will switch
the pump:
• ON, when low pressure is detected, and
• OFF, when the preset high pressure is
reached.
Spot Sprayer Calibration
Spot spraying application.

20
Calibration
GP-OMCP12-B
The larger pump models - FL3521-139 and occasionally
the FL4300-143 - which are fitted on CropPaks designed
for both spot spraying and small boom spraying have
a pressure & flow regulator fitted to allow the operator
to adjust the pressure & flow to match the nozzle
requirement for spot spraying. Generally this is within
the 1 litre per minute to 2.5 litres per minute range.
An oversized nozzle will result in insufficient pressure
and an ineffective spray pattern.
An undersized spray nozzle may cause the pump
pressure switch to cycle on and off too frequently and
create a pulsating flow from the pump.
All reputable nozzle manufacturers follow the ISO
colour-coded system for nozzle outputs. Nozzle
output charts for specific nozzles are available from
Croplands.
Step 2
Check the Nozzle Operates
Correctly
1 Fill the sprayer tank with clean water making sure
the lid filter is in place.
2 Connect the sprayer power leads to a 12 volt
battery (see battery connection instructions in
chapter 2).
3 Switch On the pump.
Check the current Croplands Optima
Buyers Guide for Nozzle information.
NOTE
Spot Sprayer Calibration
Always only use clean water when
calibrating or checking a sprayer. Never
calibrate with and toxic chemical present
in the tank. Failure to follow this instruction
can lead to poisoning and serious
illness.
CAUTION
Fill the spray tank with the lid filter in place.
Nozzle spray patterns and spray angles
should be visually checked for accuracy
and the nozzle replaced if not spraying
correctly.
NOTE
