1.8 Basic safety rules
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 prohibited for children or unassisted disabled persons to use the unit.
It is prohibited to introduce R410A in the atmosphere: R410A is a fluorinated greenhouse
gas referred to in the Kyoto Protocol with a Global Warming Potential (GWP) of 1975.
1.9 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.
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). The sound pressure levels of the individual units are listed
in the technical booklet.
• 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.
6
Measures to be adopted if refrigerant gas leaks
• Product type:
- R410A
First aid measures
• General information:
- do not administer anything to an unconscious person.
• Inhalation:
- transfer outdoors.
- use oxygen or artificial respiration if needed.
- do not administer adrenaline or similar drugs.
• Contact with eyes:
- rinse thoroughly with plenty of water for at least 15 minutes and consult a doctor.
• Contact with skin:
- wash immediately with plenty of water
- immediately remove all contaminated clothing
Measures in the event of accidental spillage
• Personal precautions:
- Move all personnel to safe areas.
- Provide adequate ventilation.
- Use personal protective equipment.
• Environmental precautions:
- Intercept the emission.
• Cleaning methods:
- Use absorbent products.
Operations with removed panels
Some of the operations and/or tests described below require the removal of the panels to access
inside the unit.
There may be hot surfaces (piping, compressor, etc.) or cold (compressor, intake separator, etc.),
sharp edges (coil fins) or moving parts (fans) even with the machine stationary.
The power supply must be disconnected before removing any panel.
Operations that require the panels to be opened must only be carried out by qualified
personnel wearing personal protective equipment.
1.10 User guidelines
• Keep this manual together with the wiring diagram in a place that is accessible by the
operator.
• Take note of the unit identification data so as to provide them to the service centre when
required (see the "Machine identification" paragraph).
• It is recommended to keep track of the operations carried out on the unit, so as to facilitate any
troubleshooting.
• In case of a fault or malfunction:
- verify the type of alarm to notify the service centre;
- immediately disable the unit without resetting the alarm;
- contact an authorised service centre;
- request original spare parts.
• Request the installer to be trained on:
- switching on/shut-down;
- shutting down for long periods;
- maintenance;
- what to do/not to do in case of a fault.
