General Information
& Specs
Tank:
All tanks are constructed from UV resistant
polyethylene. Polyethylene tanks have a very
high chemical resistance.
Due to the rotomoulding process, there can
be a variance in the overall dimensions of the
tank which in turn results in variations to the
tank capacity. For this reason, any calibration
markings should be used as a guide only.
Filtration:
Filtration is a critical part of the sprayer's
performance.
ATV75 is fitted with an inline suction strainer.
It is important that the strainer is cleaned out
regularly.
Pump:
The pump is critical to any sprayer
performance. Correct operation and
maintenance of the pump will ensure the
sprayer is able to perform to its capabilities.
Make sure the pump wires are connected up
to the correct terminals (red to positive, black
to negative).
Always flush pump with clean water after every
use. Prolonged chemical contact can severely
damage valves, diaphragms and seals.
Do not leave water in pump if sprayer is to
be left in a cold environment. The water may
freeze and cause damage to pump. Empty
pump of all water and cover the pump to
ensure this situation does not arise. If this has
not been done, and there is a possibility there
may be frozen water in the pump, wait until
any ice has thawed before using the pump.
The 12 volt pumps are positive displacement
diaphragm pumps which provide delivery upon
demand.
They are self-priming and some models are
fitted with a pressure switch which senses
the outlet pressure of the pump. The pressure
switch turns the electrical power off to the
pump at a pre-determined high pressure point.
As the outlet side of the pump is opened,
the pressure starts to drop and at a pre-
determined point (typically 40-75 psi) contacts
in the switch will lose causing the pump
to start automatically. The pump will then
pump until the pressure reaches the shut-off
pressure point.
CAUTION:
Do not adjust the pressure switch out so that
the pumping pressure exceeds the maximum
pressure for the pump.
If the flow demand is very low, the pump may
reach this high pressure point and cause
"cycling" (pump turns on and off rapidly).
This is not a problem unless the pump is
subject to continuous cycling within two
second intervals for long periods of time.
Altering the setting of the pressure switch, or
adjusting the agitation ball valve so that there
is some bypass back to the tank and altering
the adjustable conejet nozzle on the gunjet will
all remedy this situation, depending on what is
most suitable.
Chemical Induction:
Chemical should be put into the main tank
through the main tank lid. It is important to
ensure that chemical is thoroughly mixed prior
to spray application.
Nozzles:
As information regarding nozzles is specific
to those being used in your application,
no specific reference is made to nozzle
application rates or nozzle types in this
operator's manual. Goldacres suggest the
use of a current nozzle selection catalogue
for reference to nozzle sizes, outputs, spray
patterns and general spraying information.
Goldacres recommends Lechler nozzles.

Identification

When ordering parts or requesting service
information for your sprayer it is important to
quote the serial number of your machine, and
the purchase date, in order to receive accurate
information. The location of the serial number
is shown in the picture.This number is located
on the warning decal as indicated below.
