1. Introduction
Thank you for purchasing a butterfly cone fan manufactured by
GIGOLA & RICCARDI S.p.A
(from here on simply referred to as “
G&R
”). In addition to expressing our gratitude to you for
having chosen our product, we are also pleased to inform you that the product you have
purchased has been designed in accordance with the provisions contained in the
Machinery
Directive 2006/42/EC
and respects all the regulatory and legislative requirements relating to
health and safety (
Legislative Decree 9 April 2008, no. 81 – CONSOLIDATED LAW ON HEALTH
AND SAFETY AT THE WORKPLACE coordinated with Leg.Decree 3 August 2009, no. 106
). The
components which make up the machinery have not only been exclusively produced using
high-quality materials, but have also been designed, shaped and manufactured in order to
guarantee a long service life.
By drawing up an appropriate schedule for periodical checks,
and carrying out all necessary ordinary and extraordinary maintenance operations at set
times and in set ways (or immediately, should any operational issues arise), it will be possible
to increase the effectiveness and efficiency of the machine, as well as extending its general
service life.
Considering that axial fans are MACHINES (though they may be simple constructions and their
operation easy to understand) they pose an intrinsic hazard and, therefore, we advise those
who are working and/or positioned in close proximity to the machine or its working range,
either when it has been shut down or (in particular) when it is in operation, to always proceed
with caution, take heed of the safety operating procedures and always use common sense
during operation. Finally, it is to be taken into consideration that the relative elementary
nature of the fans does not lessen the responsibility of those working on the machinery and
does not give non-qualified and/or non-authorised personnel the permission to perform
operations on it.
Prior to working on the machine or any of its components
, in order to prevent the occurrence
of dangerous or potentially harmful situations (for the user, the machinery, those positioned in
close proximity and the installation itself) we
categorically advise that this operation and
maintenance manual be read thoroughly
. Should you require further or more detailed
information about the machinery, installation operations, start-up, maintenance and/or
disposal, we advise you to refer to our post-sales technical assistance service [ Ref. Par. 1.O ],
consult “our sales catalogue” or visit our website: www.gigolariccardi.com.

-the information contained in this document is in line with the technical and safety
specifications of the machine which the manual refers to;
-the instructions, drawings, diagrams, tables, technical data and other details included
in this manual are of a specific technical nature and are therefore subject to
confidentiality;
-the drawings, diagrams, tables and technical data are up-to-date as of the publication
date of this document and exclusively apply to the machinery they refer to;
-the information contained in this operation and maintenance manual is not to be used
for purposes other than those for which the information has been prepared;
-this publication forms an integral and inseparable part of the documentation supplied

entire unburnt mixture.
EXPLOSION LIMITS If the concentration of the flammable substance dispersed in sufficient
quantities in the air exceeds a given minimum value (lower explosion limit), it
is possible for an explosion to occur. This does not happen if the
concentration of gas or vapour exceeds the maximum limit (upper explosion
limit).
The explosion limits vary in non-atmospheric conditions. The range of
concentrations between the explosion limits is normally broader, for
example, with rises of the pressure and temperature of the mixture.
An explosive atmosphere can form above a flammable liquid only if the
surface temperature of the liquid exceeds a precise minimum value.
LOWER EXPLOSION
LIMIT
The lower limit of the range of concentration of a flammable substance in the
air inside which an explosion may occur.
UPPER EXPLOSION
LIMIT
The upper limit of the range of concentration of a flammable substance in
the air inside which an explosion may occur.
EXPLOSION RISK
AREAS
The areas in which explosive atmospheres can form in such quantities as to
require the implementation of measures for protecting the health and safety
of the workers involved are defined as “explosion risk areas”.
DANGEROUS
EXPLOSIVE
ATMOSPHERE
Explosive atmosphere present in an environment in quantities that are
dangerous for the health and safety of persons.
SAFE PLACE Place where persons can consider themselves to be safe from the effects of

1.E. Intended users of the manual, safekeeping
This operation and maintenance manual and all the information enclosed with it is intended
for expert users.
The safekeeping of this document must be entrusted to a responsible person who has been
specially put in charge of it.
The manual must be kept in a suitable place that guarantees both its best possible
conservation and easy traceability in case of need.
If the manual gets lost, deteriorates to the point that it is no longer readable (in whole or in
part) or is split up or damaged (missing pages or tearing of some of them), replacement
documentation must be requested directly from the manufacturer, quoting the name of this
manual.
1.F. Qualification of maintenance personnel
The concept of maintenance operation intended as a single action on the machine is
obsolete. Because they involve numerous work and organisational processes, the
operations must be looked on as a real “system” and, in this light, the qualification of
personnel, intended as an attribute that comprises a multiplicity of coexisting values that
range from organisation and management skills, technological and technical knowledge of
the machinery on which to work, becomes a factor that is not only obligatory and of
fundamental importance.
In the light of the above, the following three qualified professional figures are defined (Rif.
UNI EN 15628):

-define materials, means, equipment and workforces for
the work assigned from time to time, and ensure their
availability for the execution of the work itself within the
established times;
-ensure compliance with the safety regulations by the
coordinated personnel;
-draw up the work report on paper or electronic form, in
accordance with company procedures;
-use the maintenance IT system, if available, for all the

1.G. Work clothing and personal protective equipment
Before taking any action, personnel changed with performing work on the machinery must
wear:
-suitable and accident prevention clothing, as indicated by the standard
89/686/EEC
as amended;
-P.P.E. in conformity with
Leg. Decree 475/92
et seq., as indicated by
Leg. Decree
81/08
and seq.
It is obvious that at the moment of their use the above must be integral and in good condition
and must be replaced immediately if there are clear signs of damage or deterioration.
When necessary, the use of P.P.E. is recalled in this operation and maintenance manual by
means of pictograms inside informative boxes.
Even when the legal P.P.E. are worn, working on or with a machine is never
totally risk-free and therefore it is always necessary to work with sufficient
visibility both in the work areas and in the surroundings (even when this is not
deemed to be immediately dangerous). It is also advisable never to work
when tired, ill, injured, or under the influence of alcohol, drugs or medicines
that are capable of altering a person’s mental and physical capacities.
1.H. Contents of the manual
This document consists of 84 pages and, for simplicity of consultation, has been subdivided
into chapters that make it easy at each stage of the machine’s life (transportation,
packaging, handling, storage and stowing, installation on site ...) to find the information
required by the users of the same.
The information contained herein refers to the envisaged use of the butterfly cone fan as
defined below
[Ref. Par. 2.A ] and is addressed to users so that:
-that they have a means for learning the potential of the machine, the problems that
can arise when running it and everything associated with the maintenance of the
product, as well as its acceptance, transportation, packaging, handling, storage and
stowing, installation in the site served, assembly of the parts supplied separately,
starting up, operation, sopping, putting out of service, demolition and disposal;
-they can set up specific information, training and instruction courses for those who -
directly or indirectly - come into contact with the machinery;
the person responsible for the machine installation site;
machine users;
maintenance specialists;
maintenance engineers;
maintenance heads;
persons charged with installation, disassembly and dismantling;
visitors;
personnel from third-party companies present in the machine installation site;
Given the above it is therefore necessary to read all the chapters of this manual carefully.
The configuration of some of the machine components as well as the position of the
safety devices installed in it - and described or depicted here - may be subject to
variations in virtue of the satisfaction of particular completions linked to specific
customer needs or safety regulations. In this case:
-descriptions, references and procedures may be incomplete or inexact and
should therefore be understood as being of a “general nature”.
-drawings and photographs may differ from the reality and therefore should be
taken for reference for easier understanding of the text.

otherwise) that is supplied at the moment of purchase of the machinery.
The following are included in the standard documentation supplied herewith butterfly cone
fan:
-The EC Declaration of conformity [
Ref. Par. 17.A ];
-This operation and maintenance manual.
All the standard documentation of the butterfly cone fan supplied constitutes an integral and
inseparable part of the same (on penalty of the cessation of the guarantee).
In the case of transfer to third parties, the primary custodian of the machinery is obliged to
hand over all the machine standard documentation supplied,
integral and in a good state of
conservation,
(on penalty of the immediate cessation of the guarantee and the immediate
exclusion of the manufacturer from all objective and subjective, civil and criminal
responsibility with regard to the machinery).
Finally, in the event of transfer to third parties, the primary custodian of the machinery is
required and strongly requested to report G&R the address of the new user so that the
manufacturer can send it and notices and/or updates that are seemed indispensable.
1.J. Updates of the manual
The machine documentation complies with all the laws, directives and binding rules in force
as at 01 January 2016. Its contents reflect the state of the art at the moment of marketing of
the butterfly cone fan, of which it constitutes an integral and inseparable part [
Ref. Par. 1.I. ].
Any improvements or changes that may be made by G&R
to the aforesaid fan in the future,
inspired by:
-
new experiences;
-
new know-how acquired in the area of “ventilation techniques and technology”;
-
strategic market decisions;
-
any other reasons;
do not oblige G&R to intervene on any previous supplies of axial fans with galvanised steel
cones, nor to consider the machinery and/or associated manual to be lacking or inadequate.
G&R reserves the right to make improvements, modifications and integrations both to the
machinery and to this operation and maintenance manual, without notifying those who are
already in possession of them, save the case in which the change and/or modification lead to
the elimination, or the notable reduction, of one or more immediate and/or grave dangers
regarding health and safety) and, above all, without this constituting a justification for claims
against G&R.
Any integrations of the manual which the manufacturer deems appropriate to send to the
users, must be kept along with the operation and maintenance manual already in their
possession and handled in the same way as them.
1.K. Important information
If it is necessary to replace deteriorated or worn parts and/or ones damaged by use, time, lack of
care or anything else,
it is obligatory to use original spare parts and accessories because, the use
of non-original spares can not only cause the termination of the guarantee on the machine,
but can
be dangerous
and/or shorten the life and reduce the performance of the machine.
If the pictograms, or other labels on the machinery in addition to the identification plate, affixed by
the manufacturer (and only by it during production) deteriorate or degrade over time and following
the continued and continuative action of atmospheric agents to the point of alteration of legibility,
even of only one of the informative elements on it, it is necessary to restore/replace them
immediately.
All the spare parts can be requested directly from the manufacturer, quoting the data indicated on
the label of the machinery or the fan information data in this operation and maintenance manual.
1.L. Meaning of the pictograms affixed on the machine
