6) Stand clear of all moving equipment and “bump” the motor to confirm fan direction of rotation. 7) Also confirm the Drive Sentry has correct direction of free rotation and correct direction of restraint. 8) AFTER CONFIRMING THE DIRECTION OF ROTATION IS CORRECT thread one end of the restraining cable through the shackle and secure it using one of the two supplied cable clamps. Install the cable clamp using Loctite 262 on the clamp threads. 9) Apply Loctite 262 to the threads on the second cable clamp and secure the opposite end of the restraining cable to a sturdy support.

Pull the cable taut to remove available slack and complete the attachment with the cable no more than 10 ° above or below level. 10) Ensure the restraining cable is not attached to or exposed to a sharp edge that would cause wear and failure. 11) By hand, attempt to rotate the fan backward to confirm the Drive Sentry restrains backward rotation. 12) Install all required guards and confirm the Drive Sentry has appropriate clearances for free operation and travel. 12) After all guards are installed run the fan at a full speed test to make final confirmation of the following:

 Direction of rotation in operation  Proper clearances for Drive Sentry  Restraining cable is taut, free of slack and properly positioned 1550 S. 81 st W. Avenue  Tulsa, OK 74127 Office: 918‐241‐0264  www.airtechproducts.com
