Mount the fan according to the fan clearance for your
fan model and diameter:
• Fans require open space above the blades for air
intake and maximum performance.
• Fan blades require safe clearance to operate.
Identify any potential obstructions the fan blades
could impact.


NOTE: The blades move upward during operation.
