Residual Risks
General
In this section the most common situations are indicat
-
ed,as these cannot be controlled by the manufacturer and
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 area is the area inside the unit that be
-
comes accessible only by deliberate removal of the clad
-
ding or parts of it.
Handling
The handling operations, if implemented without all of
the protection necesssary and without due caution, may
cause the drop or the tipping of the unit with the conse
-
quent 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 compli
-
ance with the local regulations in force.
In case of refrigerant leakage, see the “Safety data sheet”
for the refrigerant.
Installation
The incorrect installation of the unit could cause water
leaks, condensate accumulation, leaking of the refriger
-
ant, electric shock, poor operation or damage to the unit
itself.
Check that the installation has been implemented by
qualified technical personnel only and that the instruc
-
tions contained in the present manual and the local regu
-
lations in force have been adhered to.
The installation of the unit in a place where even infre
-
quent leaks of inflam-mable 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
result in 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 au
-
thorised person and/or provide protection against intru
-
sion into the danger zone.
General risks
Smell of burning, smoke or other signals of serious anom
-
alies 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 re
-
solve the problem at the source of the anomaly.
Accidental contact with heat exchangers, compressors,
water pipes or other components can result in injury and/
or burns. Always wear suitable clothing including protec
-
tive gloves when working in the danger area.
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 cor
-
rect 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 in-crease 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 vicinity of the safety valve and never
leave the refrigerating system taps closed.
Electric parts
Cables not connected to the mains and/or improperly
configured cables and/or cables with inadequate protec
-
tive devices can cause electric shocks, poisoning, dam
-
age to the equipment 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
lead to the entry of dust, water etc inside and may conse
-
quently 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 appropri
-
ate sign.
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 isola
-
tor on the attachment line of the unit itself, padlock it and
display the appropriate warning sign.
