Safety precautions
WARNING !
• Take care when the cooker hood is operating simultaneously with an open fireplace or burner that
depend on the air in the environment and are supplied by other than electrical energy, as the cooker
hood removes the air from the environment which a burner or fireplace need for combustion. The
negative pressure in the environment must not exceed 4Pa (0.016 WC.). Provide adequate ventilation
in the environment for a safe operation of the cooker hood. Follow the local laws applicable for external
air evacuation.
