Residual risks
Despite having implemented and adopted all the safety measures indicated by applicable regulations,
some residual risks remain. In particular, in some operations of replacement, adjustment and tooling
maximum attention is always required in order to work in the best possible conditions.
LIST OF OPERATIONS WITH RESIDUAL RISKS
Risks for qualified personnel (electricians and mechanics):
• handling - during unloading and handling it is necessary to pay attention to all the steps listed in this
manual regarding the points of reference;
• installation - during installation it is necessary to pay attention to all the steps listed in this manual re-
garding the points of reference the installer must ensure the static and dynamic stability of the unit's
site of installation;
• maintenance - during maintenance it is necessary to pay attention to all the steps listed in this manual,
and in particular to high temperatures that may be present in the heat transfer fluid lines to/from the unit;
• cleaning - the unit must be cleaned only when it is switched off, by turning off the switch installed by
the electrician and the switch located on the unit itself. The key for interrupting the power supply must
be kept by the operator until the end of the cleaning operations. Internal cleaning of the unit must be
carried out using the protections required by current regulations. While the inside of the unit does not
contain particular hazards, it is necessary to pay the utmost attention so that accidents do not occur
during cleaning. The coils that have a potentially sharp finned pack must be cleaned using suitable
protective goggles and gloves.
During adjustment, maintenance and cleaning there are residual risks
of variable entity. Being operations that must be performed with guards disabled, it is necessary to pay
particular attention in order to avoid damage to persons and things.
Always pay close attention when performing the operations specified above. Remember that
these operations must always be performed by authorised personnel.
All work must be completed in accordance with the legal provisions relating to work safety. Re-
member that the unit in question is an integral part of a larger system that includes other compo-
nents, depending on the final characteristics of realisation and the mode of use. Therefore in the
end it is the responsibility of the user and assembler to assess the residual risks and their respec-
tive preventive measures.
SAFETY DEVICES
The unit is equipped with safety devices to prevent risks of damage to persons and for proper
operation. Always pay attention to the symbols and safety devices on the unit. It should
only
operate with the safety devices engaged and with fixed or movable guards installed correctly
and in the proper position.
If during installation, use or maintenance the safety devices have been temporarily removed
or disabled, the unit can be operated
exclusively
by the qualified technician who made this
change. It is
mandatory
to prevent other people's access to the unit. When finished, restore
the devices to their proper status as soon as possible.
