INSTALLATION OPERATIONS AND MAINTENANCE MANUAL - RXH/HiSERIES
1. INTRODUCTION
Units must be installed and operated according to the instrucons in this manual. Strict adherence to these simple instrucons
is a prerequisite to:
• eliminate or reduce shutdown me due to unexpected failures;
• improve the performance of components, resulng in energy savings;
• increase the life of components and the enre unit;
• decrease maintenance costs.
1.1 General informaon
This manual has been prepared to allow correct installaon, set-up and maintenance of the unit. Any contractual or extra-con-
tractual responsibility of the Company for damage caused to persons, animals or things, due to installaon, adjustment and
maintenance errors or improper use, is excluded. Any use other than that specied does not imply for the manufacturer any
commitment or obligaon of any kind.
This documentaon is an informave support and cannot be considered as a contract towards third pares.
The Company implements a policy of constant improvement and development of its products. It therefore reserves the right
to make changes to specicaons, ngs and documentaon at any me, without prior noce and without any obligaon to
update what has already been delivered.
1.2 Purpose and Content of the Instrucons
These instrucons provide essenal informaon for the installaon, operaon, tesng and maintenance of the machine. They
have been drawn up in accordance with the legal provisions issued by the European Union and the technical standards in force
at the me the instrucons were issued.
The local safety regulaons in force at the me of installaon must be observed.
The instrucons contain instrucons for avoiding reasonably foreseeable misuse.
1.3 Storage of instrucons
This manual and the eventual wiring diagram of the unit must be carefully stored in a suitable place, protected from dust and
humidity and easily accessible to users and operators for any further consultaon.
The instrucons must always follow the unit throughout its enre life cycle and must therefore be passed on to any subse-
quent user.
1.4 Instrucons update
It is recommended to check that the instrucons are up to date with the latest revision available.
Any updates sent to the customer should be retained as an aachment to this manual.
The Company is available to provide any informaon regarding the use of its products.
1.5 How to use these instrucons
The instrucons are an integral part of the unit.
It is compulsory for users or operators to consult the instrucons before any operaon on the unit and on any
occasion of uncertainty regarding the transport, handling, installaon, maintenance, use and dismantling of the
unit.
In these instrucons, in order to draw the aenon of operators and users to the operaons to be carried out in
safety, graphic symbols have been included that are shown in the following paragraphs.

INSTALLATION OPERATIONS AND MAINTENANCE MANUAL - RXH/HiSERIES
1.6 Residual Risks
A residual risk is any hazard that cannot be fully reduced by design and protecve techniques, or a potenal hazard that is not
obvious.
ATTENTION
This manual indicates any operaon that may generate a hazardous situaon as well as the precauonary
measures to be observed in each case.
• All units have pictograms with hazard warnings.
• The units are safe machines, provided the safety guards are not tampered with or removed.
• Technical preparaon, observance of the procedures outlined in this manual, and markings at crical points on the unit
will sll allow safe operaon.
• The following safety rules must be observed during installaon, start-up, use and maintenance of the units:
• Do not operate the unit unless it and its electrical components have been connected to the earthing system;
• Do not operate unit unless fan is connected to a duct or protected with safety mesh;
• Do not use the unit as a stand for other machinery;
• Do not use unit as a walkway;
• Do not use unit as equipment storage;
• Do not open inspecon panels while fan is running, especially in over pressure secons;
• Do not leave inspecon panels parally closed; Make sure all handles or knobs are securely closed;
• Wear personal protecve equipment before working on the unit;
• Before accessing the unit, make sure that all electrical ulies have been turned o, especially before
opening the inspecon panels, make sure that the fan is o and cannot be turned on again without the
knowledge of the person working on the unit;
• Before starng the fan, always ret the protecon cover or the closing panel of the fan secon;
• Be careful when liing the unit as its center of gravity may be severely unbalanced;
• Be careful when locking the liing ropes/hooks;
• Be careful of sheet metal edges inside the unit;
• Be careful of sheet metal edges outside the unit;
• Be aware of possible burns from heang coils;
• Be aware of dampers that may close unexpectedly.
