3. Product Features
The Philips ADD4963GY/56 water dispenser incorporates several features designed for convenience and water purity:
- UV-LED Disinfection: The advanced UV-LED light technology installed in the cold water tank kills up to 99.9% of bacteria*. The UV-LED light activates for 1 hour once the dispenser is connected to power, and operates for 1 hour every 2 hours to maintain water cleanliness.
- Efficient Compressor Cooling: The compressor cooling system provides cool water more efficiently and rapidly compared to conventional thermoelectric cooling methods.
- Wide Dispensing Area: The spacious dispensing area accommodates various sizes of cups, glasses, bowls, and even pots.
- Z-Shape 304 Stainless Steel Water Pipe: The anti-rust 304 stainless steel water pipe features a Z-shape design, ensuring it reaches the bottom of the water bottle to minimize residual water.
- Child Lock for Hot Water: A safety child lock is integrated into the hot water tap to prevent accidental hot water burns.
*Tested by SGS under laboratory conditions.
4. Setup Instructions

- Placement: Position the dispenser on a firm, level surface. Ensure there is at least 10 cm of clear space around the back and sides for proper ventilation. Avoid direct sunlight or heat sources.
- Water Bottle Installation:
- Open the bottom compartment door.
- Remove the cap from a standard 5-gallon (or compatible size) water bottle.

- Initial Priming: Before plugging in, dispense water from both the cold and hot taps until water flows continuously. This removes air from the system.
- Power Connection: Plug the power cord into a grounded electrical outlet. The dispenser will begin cooling and heating water. The UV-LED disinfection cycle will also activate.
