When the water dispenser is in use, press the heating switch, and the power supply will provide power to the "heat preservation" indicator for power-on indication. At the same time, the power supply is divided into two ways: one way constitutes a heating circuit, so that the electric heating tube is energized to heat up; the other way provides voltage for the "heating" indicator light for heating instructions. When the water in the heating tank is heated to the set temperature, the thermostat contact is disconnected, cutting off the heating and heating indicator circuit power supply.

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 heats up again, so that the water temperature is kept at 85-95°C over and over again.

Use and maintenance of drinking fountains:

1. The machine should be handled gently. When moving the compressor refrigerated water dispenser, keep it upright as much as possible. If it is tilted, the tilt should not be greater than 45 degrees, and it should be stationary for a period of time before working. .

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 tighten the drain valve after draining the remaining water in the dispenser. 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 service 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 hot water burns during draining).

4. It is best to disconnect the power when not in use at night to save energy and ensure safety when no one is using it.
