Product Description

1；protection of electricity creepage: as long as the electricity creepage is more than 0.2 amp. , the high efficiency creepage(residual current ) protective device will automatically cut off the current in 0.1 second. 2；protection of automatical micro-computer temperature control:the constant temperature device will heat automatically or cut off current, and keep the temperature set before accurately. 3；protection of over temperature：when the temperature of the water increase un-normally, the temperature protection switch will automatically cut off null line and live wire, stop heating drastically to ensure the safety of the user. 4；protection of dry-burn: the heater is made of copper, so its life will be more longer.besides, a especial device in it will protect the it from burnout if there is no water and the current has not been cut of. 5；protection of over-pressure: when the inner pressure is over 8 kg/square centimetre, the safety valve will automatically discharge pressure. 6:protection of water flow back(refluent):use unidirectional valve so the water in the inner tank will not flow back even though the water supply was cut off. 7:protection of water swash: the design can ensure the safety and protection of water swash. 8; protection of ABS safety shell (outer body): the material is ABS, it can provide the protection against corrosion and rusting and it is insulated. 9; protection of faults self-check(intelligent):that the intelligent faults self-check function and display will provide safety to user furthest.
