HOW INSTANT-FLOW MICRO WORKS
The engineered plastic case houses a series of ingeniously designed coils that instantly heat water as it flows through the vessel. A
unique power switch automatically applies electrical current to the coils when hot water is requested. The electrical current is not applied
when the water is not in use. The microprocessor is internally preset at the factory to maintain a constant output temperature with
varying flow rates.
