Ⅳ.Working principle

The technique of stepwise heating is used in this water boiler. The electrodes of
each water level and the accurate thermistor send their digital signal to the
microcomputer, then the computer control the heating element and the magnetic value
by calculating the signals, also coordinate the water temperature and the water inflow,
to make it only heat up one layer of water, boil it, then heat up another layer of water,
form in a stepwise heating cycle. Take advantage of this technique, the repeated heating
problem is eradicated, the productivity is highly increased but shorten the time to boil
the water.
--The LED display the current temperature, also the working condition of the machine
would be displayed on it.
--The PCB control the water temperature and water inflow, also it can keep the water
warm for a long time.
--Under fully automatic working, all the outlet water must have been boiled only once,
healthy to drink and safe to use.
--Safety alarm would be on if it has the danger of dry burning or if the temperature is
too high.
--Under PCB control, the failure condition would be displayed automatically.
--The top cap is of simple design, it is convenient for the user to clean the chamber
regularly.
--The back of the machine is easy to open, it need only 15 minutes to replace all the
parts, easy to maintain.
--The structure is all in stainless steel, make of beautiful and easy to clean.

is make of heat-resisting material and is according to the health standard of drinking
water. Also please have a check of the pipe to see if it has strange smell which may
influence the quality of the boiled water. The water pressure should be within 0.2-
0.4Mpa (Rate of flow≥4L/min), if it is more than 0.4Mpa, it need to add a reducing

value (please first clean up all the sundries in the new pipe before connecting to the
machine, in case that it would block the inflowing and influence the magnetic value
control.
5. The water boiler must have its dedicated power supply. Also the fuse and leakage
protector must be installed according to the product specification (the action current
of the leakage protector is 30mA).
