Filters; Cyclonefilter - Hardi NAVIGATOR 3000 Instruction Book

Filters

An EasyClean suction filter is fitted in the working zone. It has a built-in valve that closes when the filter is opened for
inspection or cleaning.
A Cyclone pressure filter is fitted to the sprayers right side just in front of the ChemLocker (optional equipment). It has a built-
in self-cleaning function.
In-line pressure filters can be fitted at each boom section as an option.
Nozzle filters are fitted at each nozzle.
All filters should always be in use and their function checked regularly. Pay attention to the correct combination of filter and
mesh size (see "Spray Technique" book).

CycloneFilter

With the CycloneFilter, the impurities that exist in the spray liquid will by-
pass the filter and be recirculated back to the tank via the return flow.

Valve (5) has three positions marked with small dots on the lever:
Position A (Marked with 1 dot): There is no return flow. Position is used
when flushing the boom if there is spray liquid in the main tank. Also
used when high spraying volume is required.
Position B (Marked with 2 dots): Normal spraying position. With return
flow to prevent clogging the filter when spraying. Position is used when
flushing the boom if the main tank is empty.
Position C (Marked with 3 dots): Flushing position, which is used if filter
is clogged. Lift and hold the lever to use this position which largely
increases return flow and cleans the filter.

DANGER! Never open the Cyclone filter unless the pressure SmartValve and suction valve are both closed (turned to
the unused position)! Otherwise spraying liquid could hit you when opening the filter and drain the main tank
contents!
ATTENTION! Use of position C is no guarantee for a clean filter. Always regularly do a visual inspection and cleaning
of the filter. If needed, see "10 hours service - Cyclone filter" in Maintenance section.
