3. Installation Instructions

- Power Off: Ensure the range hood is completely powered off and unplugged from the electrical outlet before beginning any installation or maintenance.
- Locate Filters: Identify the existing filters within your range hood. These are typically located on the underside of the hood, above the cooking surface.
- Remove Old Filters: Depending on your specific range hood model, the old filters may be held in place by clips, latches, or a simple push-and-release mechanism. Carefully disengage these fasteners and remove the used charcoal filters.
- Insert New Filters: Align the new Tieasy USCF-702 charcoal filters with the designated slots or areas in the range hood. Ensure they fit snugly and are oriented correctly according to your range hood's design.
- Secure Filters: Re-engage any clips, latches, or mechanisms to firmly secure the new filters in place. Confirm that the filters are stable and will not fall during operation.
- Restore Power: Once the new filters are securely installed, plug the range hood back into the electrical outlet and restore power.

4. Maintenance and Replacement
Charcoal filters are crucial for removing odors and grease from your kitchen air. Unlike baffle or mesh filters, charcoal filters are not typically cleaned but rather replaced.
- Replacement Frequency: The lifespan of a charcoal filter depends on your cooking habits and kitchen conditions. It is generally recommended to replace the Tieasy USCF-702 charcoal filter every 3 to 6 months for optimal performance. Heavy cooking or frequent frying may necessitate more frequent replacement.
- Signs of Replacement: If you notice a decrease in odor absorption, increased cooking odors lingering in the kitchen, or visible signs of saturation on the filter, it is time for a replacement.
5. Important Notes
- Always ensure the range hood is disconnected from power before handling filters.
- Use only genuine Tieasy USCF-702 replacement filters to ensure proper fit and performance.
- Dispose of used filters responsibly according to local regulations.
