Vacuum Transfer Kit for Granni Pot (If fitted)
This system is designed to transfer liquid chemicals
direct from a container (eg. Envirodrum, 25L drum, etc)
to the calibrated Granni Pot hopper, then to the tank.
Please see your Vacuum Granni Pot Operaters Manual
for detailed instructions for use.
To use Granni Pot Vacuum Transfer System:
1 Before transferring chemical concentrate ensure EC
operating unit is off and main tank contains about
25% of the required spraying water.
2 Follow instructions in Vacuum Granni Pot Op Manual.
3 Suction valve (D Fig 33) on your Explorer manifold
assembly is used when drawing chemicals from the
drum into the Granni Pot (FILL) and when transfer-
ring from hopper to Main Tank (EMPTY) .
4 See P14 for tips on using the drum rinse nozzle
safely for flushing chemical containers.
CAUTION! The drum rinse nozzle uses spray
liquid for rinsing containers. Always rinse chemical
containers with clean water before disposal.
5 The Vacuum Transfer hose must be flushed thor-
oughly after use to remove residual concentrate.
Store in a clean environment.
6 Always return valves to OFF / quadrant position after
filling is completed, to prevent backflow (and possible
contamination of tanks or spillage from overflow).
7 Remember to re-fit camlock cover/s after chemical
transfer is completed.
FILTERS
Filters should always be used, and their function checked
regularly.
Mesh size should always be smaller than the flow
average of the nozzles used. Therefore, pay attention to
the correct combination of filters and mesh size. Recom-
mended suction filter is 50 mesh - this allows good flow
to the pump with little restriction. Standard self cleaning
filter is 100 mesh. Refer to the following chart for correct
filter recommendations.
Suction filter screens do wear from dirt and chemical
particles. If nozzle filters continually block with chemical
particles, then use the next size coarse nozzle filter.

IMPORTANT! Note direction of restrictor (E Fig 34).
Correct restrictor choice
It is important to have a large flow through the filter. This
is achieved by choosing the restrictor size in relation to the
liquid consumption of the spray boom and pump output.
Four restrictors are supplied.To choose a restrictor refer
to
Flow in Specifications (P 32), or use the green one
(largest orifice) first.
Disconnect the hose (Fig 35) at the self cleaning filter,
place the restrictor in the hose and reconnect.
If the required working pressure cannot be obtained, the
restrictor is too large. Choose a smaller one (start with
black, then white and finally red.

Cleaning
When cleaning the filter, remove all hoses and check
there are no residues.
Standard filter size is 100
mesh. 50 and 80 mesh are
available and can be changed
by opening the filter top (re-
place the strainer). Check O-
rings before reassembling the
filter and replace them if
damaged.
Also refer to
Self cleaning filter
(P 22).
