installation and/or maintenance operations
may be carried out before deenergising the
electrical panel of the unit.
Failure to respect the safety measures mentioned above may result
in electrocution hazard and fire in the presence of any short-circuits.
DANGER
Inside the heat exchangers and the
refrigeration lines, this unit contains liquid
and gaseous refrigerant under pressure. The
release of this refrigerant may be dangerous
and cause injuries.

natural refrigerants, such as hydrocarbons.
Manufacturer may not be held liable for any
problems deriving from the replacement of
original refrigerant or the introduction of
hydrocarbons.

n The maximum working pressure values are mentioned on the
unit’s data plate.
n Suitable safety devices (pressure switches and safety valves)
must be installed on the refrigerant line when installing the unit.
n Dedicated guards (removable panels with tools) and danger signs
indicate the presence of hot pipes or components (high surface
temperature).
DANGER
It is the User’s responsibility to ensure that
