GENERAL
This section lists some of the more common situations which, being beyond the control of the manufacturer, could be a
source of risk to persons or property.
DEFINITION OF DANGER AREA
The figure below highlights the area in which only authorised personnel may operate.
- External danger zone, identified by a precise area around the unit and its vertical projection on the ground in the case of
hanging unit.
- Internal danger zone, identified by the area that can be entered only after having intentionally removed the protecting
panels or parts of these.
HANDLING
- If handling operations are undertaken without adopting all the necessary safety procedures and exercising due care,
the unit can fall or topple, causing damage — possibly extremely serious — to persons and/or property, and to the unit
itself. Ensure the unit is handled and manoeuvred as directed on the packing and in the present manual, and in
accordance with local regulations. In the event of refrigerant gas escaping, refer to the “Safety datasheet” for the
particular refrigerant.
INSTALLATION
- Incorrect installation of the unit can result in water leaks, accumulation of condensate, escape of refrigerant, electric
shocks, fire, as well as irregular operation or damage to the unit itself. Make certain that the installation is carried out only
by a qualified technician, also that the directions contained in this manual are followed and local statutory regulations
observed.
- In the event of the unit being installed in a site where there is even the slightest risk of inflammable gas escapes and
consequently the possibility of such gases accumulating in area around the unit, the risk of explosion and fire cannot be
discounted. Take every care and precaution when selecting the installation site.
- Installation on a structure not able to bear the weight and/or afford a secure anchorage of the equipment may cause the
unit to fall and/or topple, resulting in damage to persons or property, or to the unit itself. Make certain that every care and
precaution is taken when positioning and securing the unit.
- If the unit is easily accessible to children, unauthorized persons or animals, this is a situation that can give rise
accidents and injuries, perhaps serious. Install the unit in a place where access is allowed only to authorized persons, or
install barriers or guards preventing unauthorized entry.
GENERAL RISKS
- A smell of burning, smoke or other indications of serious irregularity could signal the onset of situations liable to cause
damage to persons or property or to the unit itself. Isolate the unit from the electrical power supply (red-and-yellow
switch), and contact an authorized service centre so that the source of the problem can be identified and remedied.
- Accidental contact with heat exchange coils, compressors, pressure pipelines or other components can result in
wounding or burns, or both. Always wear suitable clothing, including protective gloves, when working in the danger area.
- Maintenance or repairs carried out by unskilled operatives can result in harm or damage to persons and property, or to
the unit itself. Always contact an authorized service centre.
- Failure to close the panels of the unit, or to check that all the fixing screws of the panels are properly tightened, can
result in harm or damage to persons or property, or to the unit itself. Verify periodically that all panels are closed and
made properly secure.
- In the event of fire, the temperature of the refrigerant can rise to the point that pressure will exceed safety levels and
perhaps cause fluid to be projected. It may also happen that parts of the circuit isolated by closed valves will explode. Do
not stand near safety valves, and never leave the valves of the refrigerant circuit closed.
