Cooling system

For adequate cooling of the firewall, follow these guidelines:
•
Install the firewall at the installation site with its airflow direction meeting the ventilation
requirements.
•
Reserve a minimum clearance of 100 mm (3.94 in) around the inlet and outlet air vents.
•
Make sure the installation site has a good cooling system.
The F1000-AI-10 firewall provides front side-intake and rear side-exhaust airflow for heat dissipation.
The F1000-AI-20, F1000-AI-30, F1000-AI-50, F1000-AI-60, F1000-AI-70, F1000-AI-80, and
F1000-AI-90 firewalls provide left side-intake and right side-exhaust airflow for heat dissipation.
