5 SAFETY REGULATIONS
5.4
Precautions against residual risks
Prevention of residual mechanical risks
• Regularly carry out all the maintenance operations foreseen in this manual.
• Wear protective equipment suited to the work in hand (→ see table 4).
• Fans, motors and belt drives might be running. Before accessing them, switch off the machine, wait for them to stop and disconnect the power to the
machine.
• When opening a door or removing a panel, make sure to have a grip suitable for its weight and capable of sustaining the presence of any wind.
• The fins on heat exchangers and the edges of metal components and panels can cause cuts.
• Do not remove the guards from mobile components while the unit is operating. Make sure that mobile component guards are fitted correctly before
restarting the unit.
• The surfaces of the machine and pipes can get very hot or cold and cause the risk of scalding.
• Never exceed the maximum pressure limit (PS) of the water circuit of the unit, which is indicated on the rating plate of the same.
• Before removing parts on the pressurised water circuits, close the section of the piping concerned and drain the fluid gradually to stabilise the
pressure at the atmospheric level.
• Always wear the appropriate personal protective equipment when in the vicinity of a refrigerant circuit or when checking for leaks, for example:
- safety goggles;
- gloves;
- overalls;
- respirator (if necessary).
Prevention of residual electrical risks
• The unit contains live parts that could cause serious injury or death. Only individuals trained in electrical hazards must work on electric and electronic
components such as, for example, electrical panel, motors and wiring. During such activities, the use of appropriate personal protective equipment is
also mandatory, including, for example:
- dielectric gloves;
- dielectric shoes;
- dielectric visor;
- dielectric tools.
Before opening the electrical panel, or accessing any other electric and electronic components, disconnect the unit from the mains using the protection
device (not included in the supply).
As some components inside the electrical panel remain live even after being isolated from the mains, make sure to wait:
- three minutes in the case of electric capacitors.
- fifteen minutes in the case of frequency converters (inverters).
- If it is not known if capacitors or converters are installed, wait fifteen minutes as a precaution.
In the electrical panel, indicated in orange, there are cables that remain powered even when the protective device (not included in the supply) is open
(circuits excluded).
• Check that the unit has been grounded correctly before starting it.
• Only use power cables sized for the maximum F.L.A. current (field 19).
Installation, use and maintenance manual - Original instructions
The products are designed paying particular attention to ensuring safety during installation, use and maintenance.
However, some residual risks remain, which require precautions to be taken, as indicated below. Any activities other
than those specified in this manual (such as repairs) require a specific risk assessment and must be carried out by
trained personnel capable of recognising and preventing hazards.
For more information refer to the data book.
