Step 2

, Attach Power Unit To Mounting Hardware 

A) 

We recommend using a scissor lift to install our fans.  The best method is to place the 

power unit hub-down on the lift and raise the lift until the power unit frame touches the 

bottom of the universal mount or extension (if used). 

B)  

Once the motor frame is in contact with the mount/extension, maneuver the power unit 

as necessary to line up the mounting holes. 

C) 

Securely attach the power unit to the mount/extension using the ½” x 1½” bolts, washers, 

and nylon lock nuts included in the mounting hardware kit.  Be sure to thoroughly tighten 

all four bolts and nylon lock nuts to prevent vibration-related loosening.  Correct 

tightening is extremely important. Again, do not re-use nylon lock nuts. 

Step 3

, Attach Safety Cable

Refer to 

figure 4 

as necessary.  This step is required, omitting it will void manufacturer’s warranty! 

A) 

Slide two of the supplied large cable clamps over each end of the safety cable.   

B) 

Make a loop in one end of the cable, sliding the end back through the safety clamps. 

C) 

Feed the other end of the safety cable through the loop, making sure that the cable 

goes through the motor frame. 

D) 

Repeat step B for this end of the cable. 

E) 

Tighten the clamps securely, making sure that the u-bolts are over the free end of the 

cable, see Figure 4. 

Step 4

, Mount The Motor Control Panel 

Select a location for the MCP (Motor Control Panel) and mount securely. 

A) 

The MCP should be mounted in the upright position, vertically, with the door opening to 

the left.  Do not mount so that the door opens downward.  The mounting surface must be 

non-flammable, away from sources of heat, dust, moisture, and vibration.
