1.水泵严格禁止无水空转。第一次运行时，需要把箱内装入200mm水位。

1. The water pump is strictly prohibited from idling without water. When running for the first time, the tank needs to be filled with a water level of 200mm. <br>2. Regularly check the working condition of the nozzle. If there is no water spray, it should be removed and checked for blockage in time, and the residue in the hole should be cleaned or replaced with a new nozzle in time. <br>3. During the operation of the system, prevent water from overflowing or splashing of electrical equipment. In this case, the power supply must be cut off and the device can be restarted only after the fault has been corrected. <br>4. Check whether the liquid level element is working normally every day. If it does not work under high water conditions, the level control element can be removed and the float can be lifted manually. When the float rises to the top, the drum should rotate and the backwash pump should start working.

Check the working condition of the nozzle regularly. If there is no water spray, clear it in time and check whether it is blocked. Clean up the residue in the hole in time or replace it with a new nozzle. 3. In the process of system operation, prevent water overflow or splashing of electrical equipment. In this case, the power supply must be cut off, and the equipment can only be restarted after troubleshooting. 4. Check whether the liquid level component works normally irregularly every day. If it doesn't work at high water level, you can take off the liquid level control element and lift the float manually. When the float rises to the top, the drum should rotate and the backwash pump should start working.
