Boiling water should be placed in the indoor drying ventilation, do not install the boiling water machine in the humid environment, otherwise humid air and steam into the electrical box, easy to condensation on the surface of the insulating medium, will reduce its insulation performance, resulting in leakage of the accident. Do not place high pressure, flammable, explosive items near the boiling water, and avoid the interference of magnetic (electric) field. Installation and placement shall conform to the requirements of this note.

Please do not let the child use the water bolier alone, so as not to burn.

Avoid mounting with direct solar range. Because in the case of direct sunlight, the overall temperature of the machine will rise linearly, causing the internal electronic control system to not work properly resulting in damage.

Please use water which conforms to water quality standard, do not put into tea etc.
Do not use when water is not available. The water in the sink becomes muddy when it is used again, and the water in the sink should be replaced in time.

Water connection: Water selection to the best pure water, tap water recommended installation of Ro-Class pure water  filter. The water inlet used in this machine is a standard internal tooth interface, please check whether the waterproof rubber ring is missing in the joint when installing.Attach the water hose to the inlet and reinforce it to prevent leakage. After connecting the water source, open the water to check the interface for leakage.

Power connection: The power outlet must choose 16A Socket, the outlet needs to have the good grounding system. If necessary, please install leakage protection Switch to ensure safe use.

Working Principle

Step-type boiling water machine is starting from the bottom layer by step into the heating, gradually heating until the water is burned open energy-saving equipment. Step-type boiling machine can improve the separation of hot and cold water and ensure a boiling health of the boiling water machine, to ease the “half of the half water boiling” the degree of production. The power control ensures that only one boiling is avoided, thus avoiding repeated heating altogether. When it into a part of the water heating, and then from the bottom into another part of the water heating, until the water tank full, step type boiling water machine can be continuously out of boiling water, to avoid the traditional boiling machine after the whole box to boil the waiting time for water. The traditional boiling machine is by steam expansion from the heating box to the incubator water, the equivalent of countless times boiling. but stepping type of boiling water machine depends on the electrode temperature measurement, accurate temperature control, the effluent temperature can be set, electronic temperature control can prevent to boil water when this machine without water in it.
