General precautions
•
If the refrigerant should leak, ventilate the room. The liquid refrigerant produces toxic gas
when exposed to a flame.
•
In the case of a malfunction or spill of liquid or gas refrigerant, set the main switch to "off" and
close the shut-off valves. Promptly call technical support or professional personnel. Do not
intervene personally on the unit.
•
Based on CE Standard no. 842/2006 on certain fluorinated greenhouse gases, it is mandatory
to indicate the total amount of refrigerant in the installed system. This information is present
in the technical plate found in the outdoor unit.
•
This unit contains fluorinated greenhouse gas covered by the Kyoto Protocol. Maintenance
and disposal must be carried out only by qualified personnel.
1.9
Basic safety rules
The guidelines for the prevention of accidents reported below, with reference to the relative areas
of residual risk, must be integrated with all the general instructions of this chapter and with the
accident prevention regulations in force in the destination country of the system.
Residual risk near the machine
•
Electrocution, if the electrical connection and earthing of the machine are not carried out
correctly.
•
Cuts or abrasions due to the presence of sharp edges.
•
Suction of substances in the installation site and subsequent dispersion in the environment.
•
Projection of any object that may fall on the fan blades.
•
Leakage of water (in case of a fault).
•
Formation of condensation water and ice in the area in front of the machine during the
heating operation of the heat pump machines.
•
Micro-climate alteration (during operation).
•
Noise emission (during operation).
•
Oil leaks (due to a fault).
•
Refrigerant gas leak (due to a fault).
Refrigerant gas is a greenhouse gas effect substance. Vapours are heavier than air and they
can cause suffocation by reducing oxygen available for breathing. Rapid evaporation of the
liquid can cause freezing.
Using products that require electricity and water require some basic safety rules to be complied
with, such as:
It is prohibited to operate the unit before having disconnecting it from the power supply by
setting the main switch to "off".
It is prohibited to modify the safety devices or the settings without authorisation and
instructions from the manufacturer of the unit.
It is prohibited to pull, detach or twist the electrical cables coming from the unit, even if it
is disconnected from the power supply.
It is strictly prohibited to touch any moving parts, stand between them or introduce
pointed objects through the grids.
It is prohibited to use gas and water pipes to earth the unit.
It is prohibited to touch the unit when barefoot or with wet or damp parts of the body.
It is prohibited to stand on the unit, sit down on it and/or lean any type of object against it.
It is prohibited to dispose of and leave the packaging material in the reach of children as it
can be a potential source of danger.
It is forbidden to release R134a into the atmosphere: R134a is a fluorinated greenhouse
gas, recalled in the Protocol of Kyoto, with a Global Warming Potential (GWP)= 1430.

Residual risk
Description
The description of the residual risk considers the following elements:
•
the type of dangers those working around the machine are subject to;
•
a description of main risks;
•
who could be exposed to such risks;
•
what are the main safety measures adopted to reduce the risk of injury.
