If in doubt about the substances that can damage the
evaporator, contact the La Nuovagel S.r.l. support service
5) RESIDUES AND ENVIRONMENTAL CONTAMINA-
TION
The user is required to comply with the rules and direc-
tives in force in the country where the BLAST CHILLER
is used with regard the treatment of lubricants and fluids
possibly used in the BLAST CHILLER.
3.6
Safety devices
The blast chiller is equipped with active and passive
safety devices. Everybody entrusted with using the blast
chiller, or in any case likely to come into contact with it,
must carefully read this operation and maintenance
manual in which the hazardous areas and the relative
safety measures adopted will be described, in addition to
the so-called "residual risk" areas, i.e. those areas which,
despite the measures adopted, still present a certain
degree of danger.
WARNING!
The safety devices must not be removed or deacti-
vated for any reason; any operation carried out on
the BLAST CHILLER by deliberately excluding the
safety devices or any type of tampering with the
devices themselves is at the person's own risk.
3.6.2 Active safety devices
The following active safety devices have been adopted for
the blast chiller:
Safety pressure switch, where applicable.
Safety valve, where applicable.
3.7
Risk assessments and residual
risks
The information contained in this paragraph relates
solely and exclusively to the BLAST CHILLER, therefore
the user must integrate it with the factory risk assess-
ment where the BLAST CHILLER is installed.
The assessment of the risk deriving from the use of the
BLAST CHILLER has been carried out following the
standards and directives in force and indicated in the
paragraph "Reference Standards". In order to avoid any
hazards to persons or damage caused by residual risks,
i.e. those risks that remain despite the provisions adopt-
ed, La Nuovagel S.r.l. recommends that all personnel
working with the blast chiller follow and understand the
instructions given in the following paragraphs.
It should, however, be kept in mind that the best
safeguard for operator safety is that operator must
always exercise caution and common sense and that
greater experience acquired over time using the
machine can also contribute to improving the safety
margins in one's own work.
3.7.1 LIFTING AND TRANSPORT
3.7.1.1 Residual risks during lifting and
transport
Possible crushing and shearing of the limbs of the oper-
ators assigned to handling due to loss of load stability,
or kinetic or potential energy during handling, lifting
and/or transport operations.
3.6.1 Passive safety devices
The following devices and build solutions have been used
for the blast chiller:
Painted steel grilles (outside the cabinet) and
non-painted steel grilles (inside the cabinet) to protect
the rotating parts or technical compartments.
Hazard warning signs have been placed on the unit to
highlight the areas where particular attention must be
paid and the areas with residual risk for the safety of the
operator and exposed persons.

WARNING!
The removal of the signs or their non-replacement in
the event of deterioration means the user takes on
full liability for all the consequences that may arise or
derive from the use of the BLASTER CHILLER due to
non-compliance with the safety conditions foreseen
by the manufacturer.
