Safety instructions
Important:
Keep this manual with the unit throughout its entire service life;
Carefully read this manual before carrying out any operation on
the unit;
Y
Do not exceed the design limits given on the dataplate.
!
The safety devices on the compressed air circuit must be pro-
vided for by the user.
Before starting any maintenance operations, make sure that the
circuits are not under pressure.
Only use the unit for professional work and for its intended pur-
pose.
The user is responsible for analysing the application aspects for
product installation, and following all the applicable industrial
and safety standards and regulations contained in the product
instruction manual or other documentation supplied with the unit.
Tampering or replacement of any parts by unauthorised personnel
and/or improper machine use exonerate the manufacturer from
all responsibility and invalidate the warranty.
The manufacturer declines and present or future liability for dam-
age to persons, things and the machine, due to negligence of the
operators, non--- compliance with all the instructions given in this
manual, and non--- application of current regulations regarding
safety of the system.
The manufacturer declines any liability for damage due to alter-
ations and/or changes to the packing.
It is the responsibility of the user to ensure that the specifications
provided for the selection of the unit or components and/or
options are fully comprehensive for the correct or foreseeable use
of the machine itself or its components.
When requesting technical assistance or ordering spare parts, al-
ways quote the model and serial number on the identification pla-
te mounted externally on the unit.
IMPORTANT: The manufacturer reserves the right to modify this
manual at any time.
For the most comprehensive and updated information, the user is

2 --- Preliminary operations

The Filter, or group of Filters, must be installed as speci-
fied in the project diagram. The following should how-
ever be taken into account:
S Fig. 3 lists the technical characteristics of the Filters,
which must be respected.
S There are 5 grades of filtration available (see Tab. 1);
according to the individual installation these can be
fitted singularly or in groups of more elements (follow-
ing the progression Q(D)---P---S---C).
The final grade of removal will always depend upon
the highest grade of filtration, but the presence of
lower grade Filters upstream increase the operating
life of the more efficient Filters and thus reduce the
running costs.
S It is recommended that pre---filtration and general
filtration take place downstream of the compressor,
with final specific filtration immediately before the
individual points of application.
S If possible install Filters where the compressed air is at
its coolest and contains minimum condensate.
S Install the filter at a proper height in order allow filter
element replacement.
S If a Filter by---pass must be provided, it is suggested
that this also includes its own Filter (to prevent con-
taminated air arriving at the user).
S It is recommended to fit the optional differential pres-
sure gauge (except for Grade C) (see Tab. 2).
S Install Filters with the housing in the vertical position.
