How to Install an HVLS Ceiling Fan: Industrial Fan Installation Guide

Do not mount the fan beneath a light source, which can cause a strobing effect when the fan is operating.
Be mindful of blade clearances. Don’t install an HVLS fan too close to things like the chains or wires supporting light fixtures – this can create a safety hazard. Blade clearance should be at least 2 feet ’in every direction.
When routing the fan’s control cable, run it in a conduit or in a way that avoids lighting fixtures to avoid the possibility of signal noise and operational problems.

Use a strut channel to span three points of the building structure and create a stable attachment point for your fan. Don’t install a rigid fan mounting from a single structure such as a purlin, truss, I-beam, or bar joist.
Bolt the fan mounting plate to the attachment point using the provided hardware. The rigid mount downrod allows up to 33 degrees of adjustment for roof pitch and 5 degrees of adjustment to accommodate an unlevel beam.
While using the magnetic post level on the downrod to ensure it’s plumb, tighten all 8 locking nuts to 65 foot-pounds.
Wrap the retention safety cable from the downrod around the beam or building structure.
Ensure the retention cable length is shorter than the power cable at the motor connection. Coil the excess cable and secure it with the provided clamps.

Line up the holes from the retention cable into the fork.
Insert the clevis pin into the retention rod and secure it with the provided clip.
Connect the plug from the motor and the downrod. Twist the connector to lock.
Lift the motor assembly while feeding the studs through the downrod flange.
Gently feed the excess wire and cable through the top of the downrod.
Be sure not to pinch the cable between the motor and the downrod flange.
Secure each stud with the nylon lock nuts.

With the numbers on the blade holder facing up, insert the press studs through the holes in the blade holder.
Hand screw the nylon lock nuts onto the press studs to hold it in place.
Tighten the nylon lock nuts on the press studs using the 19mm wrench or socket.
Repeat the process for the remaining plates.

Prep the VFD for mounting to the structure.
Mount the VFD 5 feet outside the blade sweep area.
Position the VFD with the plug connector panel facing down.
Connect the motor cable from the fan to the VFD, being careful to align the pins within the connector before performing a clockwise twist to lock it in place.
Ensure the designated power over ethernet VFD is the lead drive.
Connect the ethernet communication cable to port Com 1.
Run the other side of the communication cable to the HMI.
Plug the VFD power whip into the appropriate power receptacle and twist clockwise to lock.

Secure the HVLS fan controller in a convenient location that is easy to access using the provided mounting bracket.
Ensure that the ethernet cable from the lead drive is connected to the controller.
Test the controller to ensure that everything is working properly.
