EnglishAfter the water test inspection, the method and steps are as follows:
First check the top cover of the water dispenser. If there is no smart seat, it means that the water inlet system does not have the ability to prevent secondary pollution, and this type of water dispenser is not suitable for purchase. The smart seat should be installed firmly, and the disassembly should be smooth. The thread combination of the guide post and the smart seat must be firm; if it is loose, it cannot be tightened, indicating that the thread combination of the guide post and the smart seat is not good, and the root of the guide post is easy to come out or break when used in the future.
After the bottled water is injected into the water tank (generally 2-3 times), do not press the faucet, the faucet should not drip (the faucet is sealed normally); observe the water level of the bucket, if the water level drops sharply, it means that there is water leakage in the machine (the rubber joint head comes out If there is water leakage), it is not suitable to buy; press the faucet and press your hand (after 1.5-2 seconds for cooling, and about 2-2.5 seconds for heating), water should flow out of the faucet, and the water should flow smoothly, indicating that the drinking fountain is functioning normally. If there is no water or the water comes out slowly, it means that the water inlet is blocked or the machine is abnormal.
After inserting the bucket into the smart seat, the water in the bucket will automatically flow into the hot and cold tanks. Due to the pressure difference in the bucket, there should be bubbles rising in the bucket and intermittent noises; press the faucet and press your hand, and the bubbles and noises will disappear. Indicates that the water intake is normal. Check whether the rubber plugs of the drain pipes of the cold tank and the hot tank are firm, and whether there is a snap ring to secure the rubber plugs.
