2 SAFETY
2.1 General safety precautions
The equipment operator is responsible for complying with regulatory obligations.
The equipment operator is the person who has actual control over the technical operation and free access, which means
the possibility of monitoring its components and their operation and the possibility of granting access to third parties.
The equipment operator has the power (including nancial power) to decide on technical modications, checks and repairs.
The equipment operator may give instructions to employees or to external companies for carrying out maintenance and
repair operations.
Only an authorised operator should be able to access the unit.
Installation and maintenance or repair of the unit must be carried out by personnel and companies holding a certicate
issued by a certication body designated by a member state that certies the requirements contained in Commission Re-
gulation (EC) No. 517/2014.
The internal danger zone can be accessed by removing the protective devices and entering the unit.
On no account must unqualied personnel be allowed to enter the unit and no one should be allowed to enter before the
power to it has been turned off.
The user can interact with the unit only through the control and external OK signals.
Only authorised knowledgeable personnel may access the unit in compliance with safety in the workplace regulations.
Council Directive 89/391/EEC, of 12 June 1989, on the introduction of measures to encourage improvements in the health
and safety of workers at work.
Also, knowledge and understanding of the manual are indispensable for reducing risks and for improving the health and
safety of workers.
The operator who enters the unit must have sufcient knowledge to perform the various activities throughout the technical
life of the machine.
The operator must know what to do when faced with possible anomalies, malfunctions or conditions of danger to himself or
others, and in any case, he must comply with the following instructions:
Do not do anything that goes beyond your duties and technical knowledge.
Inform the manager immediately and do not take personal initiatives.
Before carrying out any work on the unit, make sure you have turned off the power supply to it. Refer to the
section on maintenance work.

In units with capacitors and/or inverters, certain components can remain live for several minutes even after
having turned off the main switch.
Wait 10 minutes before working on the electrical parts of the unit.
Circuits supplied from external sources (made with orange cable) can remain live even after the power sup-
ply to the unit has been turned off.
Work on the unit only if there is sufcient lighting for the type of work to be carried out.
Failure to comply with the instructions in this manual and any modications made to the unit without prior written consent,
will immediately void the warranty.
The law regulating the use of stratospheric ozone depleting substances prohibits the release of refrigerant
gases into the environment and obliges owners to recover and return them to the dealer or take them to
special collection centres at the end of their operational life.
The refrigerant contained in the refrigerant circuit is included among the substances subject to special con-
trol regulations provided for by law and must therefore be disposed of as indicated above.
Particular care should be taken during maintenance operations in order to reduce refrigerant leaks as much
as possible.
2.1.1 Discharge of the safety valves
If present on the refrigerant circuit, installation requirements and/or national regulations lay down that the discharge of the
safety valves must be routed to the outside.
The conveying must be done with a pipe whose diameter must be at least that of the valve outlet, and the weight of the pipe
must not be borne by the valve.
Always direct the discharge to areas where the jet cannot cause harm to anyone.
Risk of burns following contact with hot and cold parts.

2.2 Basic rules
All the units are designed and built in compliance with Directive 2014/68/EU of the European Parliament and of the Council
of 15 May 2014 on the approximation of the laws of the Member States relating to pressure equipment.
To ensure maximum safety, in order to prevent possible risks, follow the instructions below:
- this product contains pressurised vessels, live components, moving mechanical parts and very hot and cold surfaces
that, in certain situations, can pose a risk: all maintenance work must be carried out by skilled personnel equipped with
the necessary qualications in accordance with current regulations. Before carrying out any operation, make sure that
the personnel in charge has full knowledge of the documentation supplied with the unit.
- always have a copy of the documentation near the unit.
- The operations indicated in this manual must be integrated with the procedures indicated in the user instruction manuals
of the other systems and devices incorporated in the unit. The manuals contain all the necessary information for safely
managing the devices and the possible operating modes.
- use suitable protection (gloves, hard hat, protective glasses, safety shoes, etc.) for all maintenance or control opera-
tions carried out on the unit.
- Do not wear loose clothing, ties, chains, watches, etc., which can get caught in the moving parts of the unit.
- always use tools and protective equipment in excellent condition.
- The compressors and delivery gas pipes are at high temperature. Therefore, when working in the immediate vicinity, be
careful to avoid touching any components of the unit without suitable protection.
- do not work in the discharge trajectory of the safety valves.
- if the units are positioned in unprotected places which can easily be reached by unqualied persons, suitable protection
devices must be installed.
- the user must consult the installation and use system manuals, incorporated and attached to this manual.
- there may be potential risks that are not obvious. Warnings and signals are therefore displayed on the unit.
- Do not remove the warnings.
It is expressly forbidden to:
- remove or disable the safety guards;
- tamper with and/or modify, even partially, the safety devices installed on the unit.
If there are alarm warnings and consequent tripping of the safety devices, the user must call in skilled maintenance techni-
cians to x the problem immediately.
An accident can lead to serious injury or death.
The safety devices must be tested according to the guidelines in this manual.
The manufacturer does not assume any liability for damage/injury to persons, pets or objects arising from the re-use of
individual parts of the unit for functions or assembly situations different from the original ones. Tampering with/unauthorised
replacement of one or more parts of the unit is prohibited.
The use of accessories, tools or consumables other than those recommended by the Manufacturer relieves the latter from
civil and criminal liability.
Deactivation and scrapping of the unit must be carried out only by suitably trained and equipped personnel.
The units do not fall within the scope of Directive 94/9/EC of the European Parliament and of the Council, of
23 March 1994, on the approximation of the laws of the Member States relating to equipment and protective
systems intended for use in potentially explosive atmospheres.
