Professional installation is recommended for this smart toilet. Ensure all local plumbing and electrical codes are met.
5.1 Pre-installation Checks
- Verify the rough-in distance: The distance from the center of the sewer opening to the finished wall (with tile) must be 180 mm. Incorrect measurements may prevent installation.

- Water supply: Confirm a cold water supply line is accessible.
- Drainage type: This model uses wall drainage (P-trap) by default. If floor drainage is required, a specific model for floor drainage must be ordered. Please contact customer service for guidance if your bathroom requires floor drainage or has specific water outlet/switch configurations.

- **Positioning**: Carefully position the toilet unit, aligning the drainage outlet with the floor or wall drain.
- **Secure the Unit**: Use the provided installation hardware to securely fasten the toilet to the floor.
- **Connect Water Supply**: Connect the water supply line to the toilet's inlet. Ensure all connections are tight to prevent leaks.
- **Electrical Connection**: Connect the power cord to the dedicated AC220V 50HZ outlet.
- **Test**: Turn on the main water supply and check for leaks. Perform a test flush and verify all smart functions are operational.

6.4 Hygiene and Automatic Features
- **UV Sterilization**: The spray rod utilizes UV light for sterilization, helping to eliminate bacteria and prevent cross-contamination. UV radiation is used for photolysis of bacterial protein, and at the same time, UV light ionizes oxygen in the air to form ozone, which enhances the bactericidal effect.
- **Foam Shield**: A layer of insulating foam is applied to the toilet's sealing surface to effectively prevent splashing, odor evaporation, and keep the bowl clean.
- **Automatic Lid Flip (Radar Sensor)**: The toilet features a radar sensor that can automatically open and close the lid. After a user leaves the seat, it automatically flushes.
- **No Water Pressure Limit**: The toilet is designed to operate effectively without requiring high water pressure, making it suitable for various residential settings. It has a built-in water reservoir and an automatic booster pump for strong flushing impulse.
