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.
Measures to be adopted if refrigerant gas leaks

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.

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.
