FAN PLACEMENT
BEFORE YOU BEGIN
!
ALWAYS MOUNT FAN SO THE BOTTOM EDGE OF BLADE TO THE FLOOR IS AT LEAST 10 FEET
FROM THE FLOOR AND AT LEAST 25% OF FAN DIAMETER FROM THE CEILING.
A large fan, 20 to 24 foot in diameter, performs best at 20 to 30 feet above the floor, but acceptable performance has been demonstrated
as low as 10 feet and as high as 50 ft.
Always mount fans away from the following:
Sprinkler Systems
Prior to installing fans, review all codes applicable to sprinkler systems and fans to ensure code compliance and refer to NFPA 13: Fire
Sprinkler System Installation. In any installation where fire sprinklers are present, the fan should not interfere with their operation.
•
Fans should be located at least 3 feet below a sprinkler deflector.
•
Fans should be centered between 4 adjacent sprinklers.
•
The Industrial Control Panel should be connected to a fire relay system, which can stop the fans in the event a fire occurs.
It is your responsibility that the installation complies with the applicable codes. For assistance, please call our Technical Department at
1-844-593-FANS (3267).
Walkways and Mezzanines
If the building has elevated walkways or mezzanines, mount the fans so that a person cannot reach the rotating blades in any way.
Position fans so that the tips of the blades are at least 5 feet away from any area where a person may be able to extend outward to reach
them.
Lights and Skylights
If possible, avoid mounting fans directly below lights or skylights to avoid any strobe effect caused by moving blades.
There should be a minimum of 2 feet between the blades and any light fixture.
Air Discharge Locations
Fans should not be located directly beneath any vertical air discharge. This includes air conditioning units and evaporative coolers. Such
equipment can be used effectively in conjunction with high-volume, low-speed (HVLS) fans; however the discharge of the unit must be
located outside the swept area and at a distance of at least two times the diameter of the fan. For horizontal air discharge, the fan cannot
be placed in direct path at any distance.
Windy Locations
Do not operate or install fans in outdoors or in areas exposed to wind. Failure to follow this instruction can result in death, serious injury,
or equipment damage.
Wet Locations
DO NOT locate fans where they may come into direct contact with water. These fans are only suitable for mounting in damp locations.
Other HVLS Fans
See the chart on the next page to determine proper spacing between adjacent fans.
