Important Safety Instructions
When using electrical appliances, basic precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:
- Read all instructions before using this fan.
- This fan has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
- Do not leave the fan running unattended.
- Always unplug the fan from the power outlet before moving, cleaning, or servicing.
- Do not operate any fan with a damaged cord or plug, or after the fan malfunctions or has been dropped or damaged in any manner. Return fan to an authorized service facility for examination, repair, or electrical or mechanical adjustment.
- Do not use the fan near windows, in bathrooms, or in wet locations.
- Do not immerse the fan in water or other liquids.
- Do not allow children to operate the fan without supervision.
- Keep the power cord away from heated surfaces.
- Do not insert fingers or foreign objects into any openings of the fan.
- Ensure the fan is placed on a stable, level surface to prevent tipping.
