1. The maintenance of rotary hot water meter is different from watches and other mechanical instruments. The water meter cannot be disassembled at will, nor can lubricating agents be added, nor can it be repaired by itself; Anti collision and anti cracking are required. If it is connected to the outdoor water pipe, when there is no water at night in winter, first close the water stop valve, and then open the tap to drain the remaining water, so that there is no water in the section from the valve to the water meter, so that the water meter will freeze and crack. If the indoor water pipe is frozen, do not bake it with open fire. Only 60-80 ℃ hot water can flow down the pipe to gradually thaw it, or increase the indoor temperature to thaw it.

2. The inner tank is cleaned every six months. The cleaning method is to first cut off the power supply, close the water inlet valve, then open the water outlet valve, turn the drainage switch on the safety valve 90 degrees counterclockwise, and naturally drain the water and sediment in the water heater. Then wash it with tap water. After cleaning, restore the drain switch to its original position, and pay attention to power on only after it is full of water.

3. Users who do not turn off the power supply of the rotary wing hot water meter all year round should often check whether the rotary wing hot water meter is normal, and if there is any abnormal condition, they should send it to the maintenance point for maintenance in time. When the rotor type hot water meter is used normally.

4. If the water output of shower is reduced, it is necessary to clean up the blocked sundries in time to ensure that the outlet is unobstructed, which is helpful to prolong the service life of rotor type hot water meter.

5. Never replace the parts on the rotor type water heater by yourself. It should be replaced by professional maintenance personnel or brand after-sales service personnel of the water heater.
