Operating Instructions
The Quooker Fusion Square Combi tap is designed for intuitive and safe operation, providing instant access to boiling, hot, and cold water.
Accessing Boiling Water (100°C):
- Activate Child Safety: Push the textured ring on the tap handle down twice.
- Rotate and Hold: While holding the ring down, turn it clockwise. The light ring on the tap will illuminate red, indicating boiling water is being dispensed.
- Dispense: Hold your container under the tap. The boiling water will flow as a fine spray, not a solid jet, which helps prevent scalding.
- Stop Flow: Release the ring to stop the flow of boiling water.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your Quooker Fusion Square Combi system.
Cleaning the Tap:
- Clean the exterior of the tap with a soft, damp cloth and mild detergent.
- Avoid abrasive cleaners, scouring pads, or strong chemicals, as these can damage the finish.
- For stubborn water marks, a solution of water and white vinegar can be used, followed by rinsing and drying.
Descaling the Boiler:
Depending on the hardness of your local water, the Combi boiler may require periodic descaling. Signs of limescale buildup include reduced water flow or unusual noises from the boiler. It is recommended to consult a qualified technician for descaling procedures or refer to the specific descaling instructions in the full product manual.
Filter Replacement:
While not explicitly detailed in the product description, many boiling water systems utilize filters to maintain water quality and prevent limescale. If your Quooker system includes a filter, follow the manufacturer's guidelines for replacement intervals, typically every 6-12 months, or as indicated by a service light.
