Residual safety risks
This section identifies residual hazards that cannot be eliminated during the design phase by the
manufacturer.
These risks are due to:
Precautions / Corrections
Handling
There are always risks of dropping the appliance or it falling when
moving it. Follow the instructions in the “Handling” section and all of the
required precautions in the local regulations.
Installation
Incorrect installation can cause a water leak, a gas leak, an electric
shock, a fire risk, incorrect operation or damage to the appliance. The
installation should only be carried out by qualified technical personnel.
Place the appliance in a suitable place where there is no risk of leakage
of flammable gas. Make the installation area inaccessible to third
parties.
Presence of dust/water inside the
electrical housing
Secure the electrical panel properly. Infiltrations may possibly cause
shocks and short circuits, resulting in injury to persons, damage to
property and to the equipment itself.
Ensure the appliance is earthed correctly.
Maintenance
During maintenance operations, which must always be carried out by
authorised personnel, ensure that the isolator switch is in the off position
and lock it down.
Fan
Contact with the fan may cause injury and/or death. Do not access the
appliance or remove the guards while the fan is running.
Refrigerant gas leak
Wear appropriate PPE because a gas leak can cause injury and
poisoning. Read carefully the "Refrigerant Safety Data Sheet" in the
manual. Do not use heat sources near the system until it is completely
drained.
Water leaks
They can cause damage to property and personal injury and can lead to
short circuits. We recommend connecting isolation valves.
■ All persons working on the refrigeration circuit must be able to present a certificate issued by
an industry-approved refrigerant handling capability organisation.
■ These operations facilitate the recovery and recycling of substances, thus reducing the
environmental impact in accordance with the provisions of on waste electrical and electronic
equipment (WEEE).
