Pre-Installation
Mechanical installation
•A 16-ft (4.9-m) Powersky®X6 fan weighs, at maximum, 275 lbs (125 kg). A suitable means for lifting the
weight of the fan, such as a scissor lift, and at least two (2) installation personnel will be required.
•Aero Power Fan can only be mounted to an I-beam or angle irons. If mounting to an I-beam, the I-beam
must be part of the existing building structure. Do not mount the fan to a single purlin, truss, or bar joist.
Consult a structural engineer for installation methods not covered in the guide.
•The mounting structure must be able to withstand the torque forces generated by the fan.
•Fans mounted on fabricated I-beams, which are common in steel buildings, could cause the beam to flex
and the fan to move significantly during operation. If this flexing causes a clearance problem, we suggest
installing the I-Beam Stabilizer kit.
•If the fan’s extension tube is 4 ft (1.2 m) or longer or if the mounting structure requires it, the fan’s lateral
movement must be secured using guy wires. If the fan is close to any building fixtures it is recommended
to secure the fan with guy wires as a safety measure.
•Adhere to the safety requirements in the table below when selecting where to mount the fan.
≥2 ft from all fan parts. The fan installation area must be free of obstructions such as lights, cables,
sprinklers, or other building structure. See the tables on pp. 2–3 for recommended minimum ceiling
clearances.
≥1x fan diameter if above diffuser. ≥2x fan diameter if below diffuser. Refer to the illustration below.
2.5x fan diameter, center-to-center
See the manufacturer’s requirements for the minimum clearance to combustibles.
