Setup and Installation
Before installation, ensure you have the necessary tools, including a drill, appropriate screws for your exterior wall material (not included), and caulk for sealing. The dryer vent cover must be installed in a vertical position.
- Prepare the Opening: Carefully remove your existing dryer vent hood. Ensure the 4-inch vent pipe outlet is flush with the exterior wall. Clean any lint buildup from the vent pipe opening.
- Install the Elbow Section: Detach the elbow section from the upper section of the RAEFLOW vent cover. Center the elbow's base over the vent pipe opening, ensuring the elbow's outlet is pointing upwards.
- Secure the Elbow: Mark and drill holes for mounting the elbow section to the wall. Use appropriate screws (not included) to securely fasten the elbow.
- Seal the Base: Apply caulk around the edges of the elbow's base where it meets the wall to create a weather-tight seal.
- Attach the Upper Section: Place the upper section of the vent cover onto the installed elbow. Secure it to the wall using screws through the pre-drilled holes in the upper mounting bracket.

Operation
The RAEFLOW Dryer Vent Cover operates automatically with your dryer. Its innovative design ensures efficient exhaust while maintaining a sealed exterior when not in use.
- During Dryer Operation: When your dryer is running, the hot air pressure pushes the internal floating cup upwards. This opens the vent, allowing air and lint to be expelled efficiently.
- When Dryer is Off: Once the dryer stops, the airflow ceases, and the floating cup returns to its resting position. This action seals the vent, preventing cold or hot air from entering your home and blocking unwanted pests.

Maintenance
Regular maintenance is crucial to ensure the efficient and safe operation of your dryer vent cover. Lint buildup can restrict airflow and pose a fire hazard.
- Accessing the Interior: The top lid of the dryer vent cover can be opened to access the internal floating cup.
- Cleaning the Floating Cup: Periodically remove the floating cup and clean any accumulated lint or debris from both the cup and the interior of the vent housing.
- Reassembly: Once cleaned, place the floating cup back into its position and close the top lid securely.

Troubleshooting
- Reduced Airflow: If you notice reduced airflow from your dryer, check the vent cover for lint buildup. Clean the floating cup and the interior of the vent as described in the Maintenance section. Also, inspect the entire dryer duct for blockages.
- Cold Air Entering Home: Ensure the floating cup is properly seated when the dryer is off. Check for any debris preventing it from closing completely. Verify that the caulk seal around the base is intact.
- Pests Entering Vent: Confirm that the floating cup closes fully when the dryer is not in use. Inspect the vent cover for any damage or gaps that could allow pests entry.
- Lid Not Closing Properly: Check the hinges and ensure no debris is obstructing the lid's movement.
