The AQUAH electric tankless water heaters are incorporated with China national patent technology (Patent
No. ZL 2008 2 0081568.0 with multiple safety devices. Besides, the unit has the following features.
1. Tankless, instantaneous heating for on demand hot water, no pre-heating, no stand-by heating loss, and
energy-saving.
2. Micro-computer controlled and using patent heating technology. Water is completely separated from
electricity by multi-layers of composite nano insulation material.
3. Over-temperature protection. When the output water temperature reaches 140 /60℉℃, electricity will be
cut off to avoid scalding and the screen will display E1. The appliance will start to work again
automatically when temperature drops to the set temperature.
4. Leakage protection. There is a leakage induced magnet ring. If the magnet ring detects electricity
leakage, electricity will be cut off within mil seconds and the screen will display E2.
5. Malfunction of sensor. When the temperature sensor malfunctions, the heater will stop working and the
screen will display E3
6. Conversion between Fahrenheit and Celsius.
