Important Safety Instructions
Attention!

The electric instantaneous water heaters are incorporated with China national patent heating
technology with multi-safety devices. Besides, the unit has the following features.
1. The appliance provides instant hot water. No pre-heating. No stand-by heating loss.
Energy-saving.
2. Micro-computer control, Adopting patent heating technology. Water is completely separated
from electricity by multi-layers of composite nano insulation material.
3. Over-heating function. When the outlet water temp. reaches over 67°C, the appliance will
enter into pause mode. Automatically to avoid getting scalded and the screen beeps and
displays E1. The appliance will start to work automatically while temp. drops to 58ºC
4. Creepage protection. If the unit detects electricity leakage, the electricity will be cut o by
the creepage protector and the screen displays E2.
5. Malfunction sensor, when there is malfunction with the temperature sensor, the heater stops
working and displays E3
6. Direct temperature setting, automatically thermostat, the hot water temperature sensor, the
heater stops working and displays E3.
7. Dry-heating thermal cut-o. When the heating chamber temperature is over 90°C, the
electricity will be cut o.
8. Micro-computer automatic electricity and water consumption calculating function.
