ATTENTION
The unit contains greenhouse eff ect fl uoride gases covered by
the Kyoto Protocol. The law prohibits its dispersion in the envi-

When components are removed to be replaced or when the entire
unit reaches the end of its life and it must be removed from the
installation, in order to minimise the environmental impact, respect
the following disposal requirements:
• The refrigerant gas must be fully recovered in special containers
and brought to collection centres by specialised personnel
having the necessary qualification.
• The lubricating oil in the compressors and cooling circuit must
be recovered and brought to collection centres.
• The structure, electric and electronic equipment and
components must be separated according to their type and
construction material and brought to collection centres.
• If the water circuit contains mixtures with anti-freeze, the
content must be collected and brought to collection centres.
• Observe the current national laws.
