First, unplug the quick heating type from the socket Intelligent thermostatic water heater And close the water inlet valve; Then unscrew the water outlet valve at the bottom of the water heater to drain the water and sediment inside the fast heating intelligent thermostatic water heater. Open the water inlet valve again, use tap water>intermediate water heater tank for 30 seconds, then close the water inlet valve, the water inside the constant speed intelligent thermostatic water heater is drained again, open the water inlet valve again, use tap water to flush the water heater tank for 30 seconds (twice in total), and do not block the water outlet of the instantaneous intelligent thermostatic water heater during the cleaning process.

After cleaning, return the drain switch of the fast heating intelligent thermostatic water heater to its original position. Open the water inlet valve, fill the quick heating intelligent constant temperature water heater with water, and then power on to heat it to the maximum temperature. Unplug the power plug of the fast heating intelligent constant temperature water heater from the socket again, close the water inlet valve, take a bucket and place it under the fast heating intelligent constant temperature water heater, carefully unscrew the water outlet valve at the bottom of the fast heating intelligent constant temperature water heater, and discharge the hot water inside the fast heating intelligent constant temperature water heater as much as possible; Then flush the tank of the water heater with tap water for 30 seconds according to the above method.

The main purpose of heating is to make use of the principle of thermal expansion and contraction of objects, so as to make it easier to remove the scale and dirt on the inner tank of the fast heating intelligent constant temperature water heater and the surface of the heating tube. So far, the whole cleaning is completed.

It is recommended that the DIY fast heating intelligent constant temperature water heater be cleaned by someone every three years, and a small cleaning can be done every six months. The cleaning steps are not complicated, and can be completed by DIY.

Step 1: Unplug the socket and close the two angle valves.

Step 2: unscrew the nut of the hot water outlet and block the hot water outlet to prevent water from flowing out of the water heater. At the same time, unscrew the nut of the cold water outlet, connect the hose (sprinkler pipe is enough) to drain water until no water flows out of the cold water outlet. For a 50L water heater, drain water for about one hour.

Step 3: Remove the hose connected to the cold water port, connect one end of the hose to the hot water port and the other end to the faucet, open the faucet to fill water for 1 minute, and plug the cold water port, let the cold water stay in the tank for a while, then open the cold water port to drain water, and repeat several times until the discharged water is clean.

Step 4: Screw on the nuts of the cold water port and the hot water port, open the triangle valve, and open the hot water at the water heater faucet. When the water flows out, close it.
