READ AND SAVE THESE INSTRUCTIONS
TO REDUCETHE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, disable the ventilator by covering the solar panel with cardboard or disconnecting the wires from the motor terminals (note wire locations when disconnecting).
3. Installation work must be done by a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
4. If removing an existing 120 VAC powered attic ventilator, use only a qualified person(s) to remove any electrical wiring in accordance with all applicable codes and standards.
5. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer's guidelines and safety standards such as those published by the National Fire Protection Association (NFPA), and the
American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
6. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power
3. This unit has an unguarded impeller. Do not use in locations readily accessible to people or animals.
4. This ventilator operates when the solar panel is exposed to sun light. To reduce risk of injury while installing, servicing or cleaning unit, cover the solar panel with cardboard or disconnect the wires from the motor terminals (note wire locations when disconnecting).
5. The recommended open air inlet for this ventilator is 4.25 square feet. The best location for these air intake vents are under the eaves with direct access to the attic. Failure to provide these intakes could cause natural-draft gas appliances to backdraft.
6. Your attic fan installation will create a screened opening into
your attic space. During a heavy rain storm there could be a light spray of rain into this attic space. This is a normal condition with all attic ventilators and will not cause any damage to the structure. We recommend that you do not store any valuable articles directly under the fan opening in the roof.
7. This ventilator is intended for roof installation. Broan Models
353 & 353SOBK Gable Mount Ventilators are available for side wall applications.
8. The plastic ventilator dome and base may be painted with high quality paint. Follow the paint manufacturer's recommendations for acrylic and ABS plastic as appropriate. Take care to avoid getting paint on the solar panel.
9. Please read specification label on product for further information and requirements.
10. The installation instructions contained in this document are only a recommendation and individual professionals may have their own methods of installation. If your roof has an existing warranty, installation of this product by anyone other than those who installed the roof may jeopardize any future warranty claim. Please check with the original installer of your roof if this is a concern.
