2 SAFETY
2.1 SYMBOLS USED
During normal air conditioning system design work or unit
installation, greater attention must be paid in certain situations
requiring particular care in order to avoid injuries and damage to
the unit, the installation or the building or property.
Situations that jeopardise the safety of those in the surrounding
area or that put the unit itself at risk will be clearly indicated in
this manual.
To indicate these situations, a series of special symbols will be
used to clearly identify these situations.
Pay close attention to these symbols and to the messages
following them, as your safety and that of others depends on it.
DANGER
• The text following this symbol contains information and
instructions relating directly to your safety and physical
wellbeing.
• Not taking these instructions into account could lead to serious,
very serious or even fatal injuries to you and others in the
proximities of the unit.
