Flushing the lines
Flushing the lines means to let a given
amount of oil ow through them so as
to ensure a proper "washing" of the
whole system, a correct cleaning and
the absence of dirt, contaminated
material or processed waste inside the
lines before installing the nozzle.
The ushing operation must be carried
out on all lines, upstream the nozzle. In
case the system is equipped with more
than one nozzle, ush the lines which
supply the nozzles farthest away from
the supply pump rst, then proceed
with the lines of the nozzles situated
nearer the pump.

Preliminary checks of the METER
• Make sure that the threaded end tted
on the exible hose is suitable for the
swivel of the METER provided with:

The ushing procedure depends on the
type and features of the system and
must be carried out by trained and
quali ed personnel in compliance with
the procedures set down by the
installer.
Warning
This operation is absolutely
necessary with NEW INSTALLATIONS
or if the lines used are contaminated.
You need not carry out this
procedure when replacing the nozzle
in use.
The lter of the METER, characterized by
a large ltering surface, has been
designed to guarantee a correct ltering
and a low pressure loss.
To remove and re-install the lter refer
to paragraph "H2".
Warning
The absence of the lter or its
improper installation may cause the
meter or the METER valve to block if
dirt is present in the tubes. This
situation may occur especially during
Filter
new installations.
To solve these problems consult a
quali ed Service Centre.
