Installation Instruction for Isolation Base Fastener Kit

Align the holes in the Fan Mounting Angle of the assembled fan with the holes in the Isolation Base. Utilize the largest bolt possible along with the appropriate washers and nuts. Place the correct flat washer on the provided SAE Grade 5 bolt followed by the matching sized bevel washer. Insert the bolt/washer assembly through the bottom of the hole in the Isolation Base and Fan Mounting Angle. Be sure the bevel washer is aligned properly so the bolt protrudes from the hole perpendicular to the Fan Mounting Angle. Next, place the other flat washer of the same size on the bolt followed by the lock-washer of the same size. Fasten the assembly with the matching size hex nut. Install and hand-tighten all hardware assemblies to ensure proper alignment, then torque each to their specified value as follows:
