Universities have been in school for some time now, and the topic of campus drinking water safety has regained public attention. After a semester of work, campus water heaters will once again shoulder the heavy responsibility of providing safe and healthy drinking water for everyone. To prevent bacteria from breeding and causing secondary pollution when the water dispenser is left unused for a long time, please make sure to give it a SPA to clean before resuming work!

1. Pipeline emptying

Firstly, close the inlet valve and power supply, and open the drain pipe behind the water dispenser to drain the remaining water; Then, adjust the temperature regulating valve of the exchanger to a higher temperature, open the outlet tap, and drain water for about 3 minutes to drain the trapped water in the pipeline and sterilize the pipeline at high temperature.

2. Cleaning filter element

First, use a special wrench to loosen the outer shell of the filter element, take out the filter element, rinse it under the faucet, rinse it clean, and then install it back into the filter barrel; Then, make sure that the toggle switch is in the water inlet state, open the inlet valve, turn on the power and outlet faucet, until there is water flowing out of the faucet, and drain for 1 minute.

Kind reminder: The filter element of the water heater usually needs to be replaced within 6-12 months. Each school can determine whether to replace the new filter element based on its own water environment.

3. Machine disinfection

In addition to cleaning the inside of the campus water dispenser, cleaning the outside of the machine is also important because these parts come into direct contact with the air, which can easily accumulate bacteria and cause secondary pollution of drinking water. So we need to use neutral cleaning solution or alcohol to clean the surface of the drinking water dispenser, and be careful not to use acidic and alkaline cleaning solutions to avoid corroding the outer wall of the water dispenser and affecting its appearance.
