Design and Comfort Features
The DL-1109CWS is designed for user comfort and hygiene. The heated seat features a silver-ion antibacterial surface that inhibits bacterial growth, ensuring a clean user experience. The seat temperature can be adjusted to three levels (off/low/medium/high) via the control panel, allowing users to select the most comfortable setting. The seamless stainless steel nozzle is more hygienic and durable than plastic nozzles. It self-cleans before and after each use, and its position can be adjusted for optimal cleansing.
Washing Technology
The unit uses pulse water flow technology, which creates a gentle yet effective cleansing stream by mixing air with water. This not only provides a more comfortable washing experience but also conserves water. The tank-type water heater stores 0.85 L of water, ensuring a consistent supply of warm water during use. The water temperature is adjustable, so users can select their preferred temperature. Washing modes include rear cleansing, feminine wash, and soft wash, providing options for different user needs.
Installation and Maintenance
The DL-1109CWS is designed for straightforward installation on standard toilets. It comes with a fixing plate, adjustment plates, a flexible water supply hose, and a T-connector. The installation dimensions require the distance from the water tank to the front of the toilet to be ≥495 mm. The product includes an automatic power-saving system that manages seat heating and water temperature based on usage patterns. The nozzle self-cleaning function minimizes manual maintenance. The product was discontinued in October 2022 but remains in use in many households.
