12.1 - RESIDUAL RISKS
General
In this section the most common situations are signalled. As
these cannot be controlled by the manufacturer these could
be a source of risk situations for people or things.
Danger zone
This is an area in which only an authorised operator may
work. The danger zone is the area inside the unit which is
accessible only with the deliberate removal of protections or
parts thereof.
Handling
The handling operations, if implemented without all of the
protection necesssary and without due caution, may cause
the fall or the tipping of the unit with the consequent damage,
even serious, to persons, things or the unit itself. Handle the
unit following the instructions provided in the present manual
regarding the packaging and in compliance with the local
regulations in force.
Should the gas refrigerant leak please refer to the refrigerant
"Safety sheet".
Installation
An incorrect installation of the unit could cause water leaks,
condensate accumulation, leaking of the refrigerant, electric
shock, bad functioning or damage to the unit itself.
Check that the installation has been implemented by qualified
technical personnel only and that the instructions contained in
the present manual and the local regulations in force have
been adhered to. The installation of the unit in a place where
even infrequent leaks of inflammable gas and the
accumulation of this gas in the area surrounding the area
occur could cause explosions or fires. Carefully check the
positioning of the unit. The installation of the unit in a place
unsuited to support its weight and/or guarantee adequate
anchorage may cause the fall or the tipping of the unit with the
consequent damage to things, people or the unit itself.
Carefully check the positioning and the anchoring of the unit.
Easy access to the unit by children, unauthorised persons or
animals may be the source of accidents, some serious.
Install the unit in areas which are only accessible to
authorised person and/or provide protection against intrusion
into the danger zone .
General risks
Smell of burning, smoke or other signals of serious anomalies
may indicate a situation which could cause damage to people,
things or the unit itself. Electrically isolate the unit (yellow-red
isolator).
Contact the authorised service centre to identify and resolve
the problem at the source of the anomaly.
Accidental contact with exchange batteries, compressors, air
delivery pipes or other components may cause injuries and/or
burns. Always wear suitable clothing including protective
gloves to work inside the danger zone.
Maintenance and repair operations carried out by non-
qualified personnel may cause damage to persons, things or
the unit itself.
Always contact the qualified assistance centre.
Failing to close the unit panels or failure to check the correct
tightening of all of the panelling fixing screws may cause
damage to persons, things or the unit itself. Periodically check
that all of the panels are correctly closed and fixed. If there is
a fire the temperature of the refrigerant could reach values that
increase the pressure to beyond the safety valve with the
consequent possible projection of the refrigerant itself or
explosion of the circuit parts that remain isolated by the
closure of the tap. Do not remain in the proximity of the safety
valve and never leave the refrigerating system taps closed.
Electric parts
An incomplete attachment line to the electric network or with
incorrectly sized cables and/or unsuitable protective devices
can cause electric shocks, intoxication, damage to the unit or
fires. Carry out all of the work on the electric system referring
to the electric layout and the present manual ensuring the use
of a system thereto dedicated. An incorrect fixing of the electric
components cover may favour the entry of dust, water etc
inside and may consequently can electric shocks, damage to
the unit or fires.
Always fix the unit cover properly. When the metallic mass of
the unit is under voltage and is not correctly connected to the
earthing system it may be as source of electric shock and
electrocution.
Always pay particular attention to the implementation of the
earthing system connections. Contact with parts under voltage
accessible inside the unit after the removal of the guards can
cause electric shocks, burns and electrocution.
Open and padlock the general isolator prior to removing the
guards and signal work in progress with the appropriate shield.
Contact with parts that could be under voltage due to the start
up of the unit may cause electric shocks, burns and
electrocution.
When voltage is necessary for the circuit open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning shield.
Moving parts
Contact with the transmissions or with the fan aspiration can
cause injuries. Prior to entering the inside of the unit open the
isolater situated on the connection line of the unit itself,
padlock and display the suitable sign.
Contact with the fans can cause incurie.
to removing the protective grill or the fans, open the isolator on
the attachment line of the unit itself, padlock it and display the
appropriate warning sign.
Refrigerant
The intervention of the safety valve and the consequent
expulsion of the gas refrigerant may cause injuries and
intoxication. Always wear suitable clothing including protective
gloves and eyeglasses for operations inside the danger zone.
Should the gas refrigerant leak please refer to the refrigerant
"Safety sheet".
Contact between open flames or heat sources with the
refrigerant or the heating of the gas circuit under pressure (e.g.
during welding operations) may cause explosions or fires.
Do not place any heat source inside the danger zone.
The maintenance or repair interventions which include welding
must be carried out with the system off.
Hydraulic parts
Defects in ducting , the attachments or the cut-off parts may
cause a leak or water projection with the consequent damages
to people, things or shortcircuit the unit.
