1. Introduction
Thank you for purchasing a Moplen cone fan 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:

transporting the “energies” to supply in order to “serve” parts or
entire buildings.
PRODUCTION UNIT Factory or structure intended for the production of goods or
services, provided with financial and technical-functional autonomy.
SAFETY COMPONENT
A component, provided that it is not a piece of interchangeable
equipment, that the manufacturer, or its established representative
in the European Union, markets for the purposes of ensuring a
safety function by means of its use, and the poor operation of which
jeopardises the health or safety of exposed persons.
PERIODICAL CHECK The set of operations to perform at intervals of at least six months,
for checking the complete and correct operation of the equipment
and plants.
EXPLOSION A sudden oxidation or decomposition reaction which creates an
increase in temperature or pressure, or both simultaneously.
EXPLOSIVE
ATMOSPHERE
An explosive atmosphere is intended as a mixture of air, in
atmospheric conditions, with substances that are flammable at the
gas state, vapours, mists or powders in which, following ignition,
combustion propagates to the 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

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;

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 83 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 Moplen 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 Moplen cone fan:
-The EC Declaration of conformity [
Ref. Par. 17.A ];
-This operation and maintenance manual.
All the standard documentation of the Moplen 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 Moplen
cone fan.
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 Moplen cone, 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.

2. General features of the machinery
2.A. Envisaged conditions of use and features
The Moplen cone fan is specifically designed to function as:
-an extractor of air that has been “altered” or “contaminated” by highly
aggressive/corrosive agents (e.g. air from breeding farms, greenhouses and/or factory
buildings).
-extractor of “exhausted” air.
If combined with the cooling pad, the Moplen cone fan can be used for lowering the temperature of
the internal environments (cooling).
All uses other than the one indicated are not only unauthorised but also
dangerous.
G&R declines all and every responsibility, objective and subjective,
civil and criminal, deriving from the non-application and/or non-compliance with
the rules of behaviour recalled in this operation and maintenance manual.
2.B. Main aspects linked to operation
The processing of the exhausted air, highly contaminated by extremely aggressive/corrosive
agents, is done by the extraction unit in the following three stages:
-Suction of the air through a plastic duct (
Venturi nozzle );
-Transfer of energy to the extracted air by means of an axial impeller fitted with curved
lamellar blades inside an annular manifold;
-Ejection by means of a conical diffuser of the air processed by the impeller.
A shutter interacts with the impeller by means of a mechanical drive system (centrifugal opening)
moved by the impeller itself. The user cannot control the degree of opening and/or closure of the
shutter.
