1. 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;

Do not exceed the design limits given on the dataplate.

e 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.

e 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 instruc-
tion 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.

e 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.

e manufacturer declines any liability for damage due to altera-

tions and/or changes to the packing.

It is the responsibility of the user to ensure that the specifi cations
provided for the selection of the unit or components and/or op-
tions 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 identifi cation plate

mounted externally on the unit.

IMPORTANT:Th

e manufacturer reserves the right to modify

this manual at any time.

For the most comprehensive and updated information, the user
is advised to consult the manual supplied with the unit.

2. Introduction

Foreword

Read this manual carefully to ensure that you install and operate
this unit correctly.

Transport / Handling

• Do not leave the unit in the open air.

• Use lift ing equipment of suitable capacity to lift and move the

unit (fork lift etc.).

• Protect the unit from impact to prevent damage to internal

components.

• Th

e manufacturer assumes no liability for damages

• Which may be caused by decayed or modifi ed packaging.

Inspection

As soon as you receive the unit, check its condition;

if you notice

any damage inform the carrier immediately.

3. Preliminary operations

e Filter, or group of Filters,must be installed as specifi ed in the

project diagram. Th

e following should however be taken into ac-

count:

• Fig.4 lists the technical characteristics of the Filters, which

must be respected.

• Th

ere are 5 grades of fi ltration available (see Tab. 1); according

to the individual installation these can be fi tted singularly or
in groups of more elements (following the progression Q(D)-
P-S-C) . Th

e fi nal grade of removal will always depend upon

the highest grade of fi ltration, but the presence of lower grade
Filters upstream increase the operating life of the more effi

cient

Filters and thus reduce the running costs.

• It is recommended that pre-fi ltration and general fi ltration

take place downstream of the compressor, with fi nal specifi c fi l-
tration immediately before the individual points of application.

• If possible install Filters where the compressed air is at its

coolest and contains minimum condensate.

• Allow space around the Filter to open it for substitution of the

element.

• If a Filter by-pass must be provided, it is suggested that this

also includes its own Filter (to prevent contaminated air arriv-
ing at the user).

• It is recommended to fi t the optional diff erential pressure

indicator or gauge (except for Grade C) (see Tab. 2).

• Install Filters with the housing in the vertical position.

4. Installation

Install the fi lter(s) as follows:

a) If necessary, fi t the optional diff erential pressure gauge (see Tab.

2) onto the fi lter, as described in the respective manual. Fig. 3
shows the connections on the fi lter.

b) If necessary, mount the fi lters in series by attaching the respec-

tive fl anges together (inlet to outlet).

c) Fit the optional counterfl anges (if supplied) onto the fi lter inlet

and outlet connections (see Fig. 1).

d) Check the piping where fi lters will be connected can sustain

the weight.

e) Connect the fi lter(s) to the compressed air piping (for air con-

nection sizes see Fig. 3) by attaching the inlet and outlet piping
to the connections on the fi lter, respecting the inlet/outlet labels
on the fl anges.

f) Open the shut-off valve upstream of the fi lter. Allow compressed

air to blow through the piping for a fewminutes to remove any
solid impurities coming from the distribution network. Th

close the shut-off valve.

g) Fit the element(s) into the fi lter, as described in the instructions

which accompany them.

h) Grades D, Q, P and S:

Write the Filter installation date on the

“Remember to change your Filter Element” label and stick it
onto the Filter housing.

Grade C:

Stick the Filter performance graph, supplied in the

packing, onto the Filter housing.

i) Fit the separately supplied condensate drain to the bottom of
