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�
ATV200, 300 & UV400 are 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�
