1. The maintenance of the rotary-type hot water meter is different from watches and other mechanical instruments. The water meter should not be dismantled at will, and no lubricant should be added, nor can it be repaired by itself; it should be protected against collision and cracking. Connected to the outdoor water pipe, when there is no water in the winter night, first close the water stop valve, then open the faucet to release the remaining water, so that the valve does not enter the water meter section, and the water meter is frozen. If the indoor water pipe is frozen, it should not be baked with open flame. Only 60-80 °C hot water can be used to flow down the pipe to make it gradually freeze, or to increase the indoor temperature to thaw.
2. The inner tank is cleaned once every six months. The cleaning method is to first cut off the power supply, close the inlet valve, and then open the outlet valve to rotate the drain switch on the safety valve counterclockwise by 90 degrees to naturally drain the water and sediment in the water heater. Then wash with tap water. After cleaning, return the drain switch to the original position, and pay attention to the power supply after the water is full.
3. Users who do not turn off the rotary-type hot water meter power supply should always check whether the rotary-type hot water meter is normal. If there is any abnormal situation, it should be sent to the maintenance point for maintenance. In the case where the rotor type hot water meter is used normally.
4. If the amount of water discharged from the shower is reduced, it is necessary to clean up the clogged debris in time to ensure that the outlet is unobstructed, which is helpful for extending the service life of the rotary-type hot water meter.
5. Never replace the parts on the rotor-type hot water meter by yourself. It should be replaced by the professional maintenance personnel of the water heater or the brand after-sales service personnel.
