Adherence to the paragraphs pertinent to the above mentioned harmonized norms has allowed for the elimination or reduction of
the risks in the best possible way, both during normal functioning, and during the regulation and maintenance operations, for the
entire life-cycle of the machine.
The components used have been accurately chosen among those available on the market and the materials of which the machine
is made of (and the accessory instruments of the machine) are void of risks to the health and integrity of the persons. All the parts
supplied by third parties are marked CE (where required) and compliant to the relative guidelines of reference. All the details have
been strictly controlled, in compliance to the quality standards established by the norms in force.
The warning and protection measures necessary with respect to the residual risks have been, furthermore, implemented on the
machine (please see, in this respect, Paragraph 3.3 - Warnings concerning the Residual Risks).
3.2 Protection Devices and Solutions
3.2.1 Passive Safety Devices
The devices and the constructional solutions described hereinafter have been applied to the machine.
Fixed guards, on both sides of the machine, which enclose the body of the condensing unit and of the evaporator.
Fixed guards in metallic or plastic mesh, in proximity of the mobile parts.
Safety signals in proximity of the fixed guards of the machine.
3.2.2 Active Safety Devices
The active safety devices described hereinafter have been applied to the machine.
Safety pressure switch on the compressor.
Safety thermostat on the finned resistances of the heat exchanger.
Secure valve (when provided)
3.3 Residual Risk Warnings
To avoid all dangerous conditions for people or damage to the machine caused by residual risks, i.e. those risks that persist
despite all the devices implemented, or potential risks that are not obvious, the manufacturer recommends the operators,
maintenance staff and all staff working on the machine scrupulously follow the warnings on the following pages.
WARNING
3.3.1 Lifting and Transportation
3.3.1.1 Residual Risks During Lifting and Transport Phases
During the lifting and transport phases, risks are present related to:
operations on the machine by staff that is unqualified, untrained, uninformed or not correctly equipped.
wrong choice or wrong use of transport and movement vehicles (for example, forklift or hoist) for the machine;
crushing of operators responsible for movement;
loss of load stability during the operations in question;
projection of mobile parts of the machine that cannot be adequately removed or fastened;
knocking of parts or machine components with people or property due to sudden movements of the machine or incorrect
behaviour of the employees conducting the operation;
knocking or falling of machine components, damaging the machine and the relative protections;
possible unhealthy or excessively forced movements by transport and movement operators of the machine components.
