This unit has been subjected to risk analysis under EC Directive 98/37/CEE (89/392/CEE): it is built to perform the
functions for which it was designed without risk as long as the installation, operation and maintenance of the
unit are all carried out according to the instructions in this manual and on the labels on the unit.
The risks which are particularly important for the safety of the user are marked with the danger symbol.
IMPORTANT WARNINGS
This unit contains refrigerant circuits under pressure, live electrical components, hot surfaces, sharp edges (e.g. the
coil) and rotating devices (e.g. fans). Before opening the unit, disconnect it from the electrical power supply.
All service and maintenance operations must be performed when the unit is off and must be done by
qualified and experienced personnel who are aware of the necessary precautions.
In any case, all safety legislation of the installation location must be followed.
In the event of fire, water and other conductive substances must not be used to put out the fire near live electrical
components. This warning must be displayed on notices in the unit installation location.
If the refrigerants used come into contact with fire they decompose, forming acids and other irritants. The smell of
these substances, even at concentrations below danger levels, gives enough warning to allow evacuation of the
area at risk.
Electronic components are sensitive to electrostatic discharges from the human body. Touch an earth contact
before handling any electronic component.
Make sure that the power supply voltage corresponds to the value shown on the data plate.
