purchaser.

No Other Warranties: This Limited Warranty contains the Company’s sole obligation and your sole
remedy for defective products. The foregoing warranties are exclusive and in lieu of any other war­ranties, express or implied. THE COMPANY DISCLAIMS AND EXCLUDES ALL OTHER EXPRESS

WARRANTIES, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES IMPLIED BY LAW, INCLUDING
WITHOUT LIMITATION THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PUR­POSE. To the extent that applicable law prohibits the exclusion of implied warranties, the duration

of any applicable implied warranty is limited to the period specified for the express warranty above.
Some states do not allow limitations on how long an implied warranty lasts, so the above limita­tion may not apply to you. Any oral or written description of the Product is for the sole purpose of
identifying it and shall not be construed as an express warranty.

Whenever possible, each provision of this Limited Warranty shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision is held to be prohibited or invalid,
such provision shall be ineffective only to the extent of such prohibition or invalidity, without invali­dating the remainder of such provision or the other remaining provisions of the Limited Warranty.

Remedy: During the applicable limited warranty period, the Company will, at its option, provide
replacement parts for, or repair or replace, without charge, any Product or part thereof, to the extent
the Company finds it to be covered by and in breach of this limited warranty under normal use and
service. The Company will ship the repaired or replaced Product or replacement parts to you at no
charge. You are responsible for all costs for removal, reinstallation and shipping, insurance or other
freight charges incurred in the shipment of the Product or part to the Company. If you must send the
Product or part to the Company, as instructed by the Company, you must properly pack the Product
or part—the Company is not responsible for damage in transit. The Company reserves the right to
utilize reconditioned, refurbished, repaired or remanufactured Products or parts in the warranty repair
or replacement process. Such Products and parts will be comparable in function and performance

The ducting from this fan to the outside of the building has a strong effect on the
air flow, noise and energy use of the fan. Use the shortest, straightest duct routing
possible for best performance, and avoid installing the fan with smaller ducts than
recommended. Insulation around the ducts can reduce energy loss and inhibit
mold growth. Fans installed with existing ducts may not achieve their rated airflow.
