When the water dispenser is in use, press the heating switch, and the power supply will provide power for the "keep warm" indicator light as a power-on indication. At the same time, the power supply is divided into two circuits: one circuit constitutes a heating circuit, which makes the electric heating tube energized to heat up; When the water in the hot tank is heated to the set temperature, the contact of the thermostat is disconnected, cutting off the power supply of the heating and heating indicating circuit.
The "heating" indicator light goes out, and the electric heating tube stops heating. When the water temperature drops to the set temperature, the thermostat contacts are connected to the power circuit, and the electric heating tube reheats, so that the water temperature is kept between 85-95 °C over and over again.
Use and maintenance of the water dispenser:
1. The handling machine should be handled with care. When moving the water dispenser cooled by the compressor, it should be kept upright as much as possible. If it is to be tilted, the tilt should not be greater than 45 degrees, and it must be stationary for a period of time after handling before it can work. .
2. When using the water dispenser for the first time, clean the containers and pipelines of the water dispenser with clean water, then unscrew the drain valve, and then tighten the drain valve after draining the remaining water in the machine. After adding a large bottle of water, turn on the hot water faucet, plug in the power supply and turn on the heating switch after the water flows out, to avoid dry burning and prolong the life of the machine.
3. If the water dispenser is out of use for a long time, please turn off the machine switch and unplug the power plug, then unscrew the drain valve, drain the remaining water in the machine, and then tighten the drain valve (please pay attention to the hot water scald during the draining process).
4. It is best to disconnect the power supply when not in use at night, which can save energy and ensure safety when no one is using it.
