Precautions for operating the water washing sieve residue determination device

Precautions for operation:
1. When this device is put into use, it must be operated according to the operation steps, and the flushing water flow should be kept free of impurities to avoid errors in the measurement of sieve residue. Therefore, the status of the water filter cartridge in the water filter should be checked regularly (every 3 months). If there is damage, severe corrosion by water rust, or other factors that affect the water filtration effect, the water filter cartridge should be replaced in a timely manner.
2. After the device is put into use, the power should be cut off, and the flushing valve, drain valve, and water pressure regulating valve handle should be closed in sequence to release the clean water inside the device. At the same time, the device should be kept clean.
3. If this device is not used temporarily, the clean water booster pump must be operated once a week and discharged for 2 minutes to prevent impurities or rust in the water pipe from jamming the impeller of the water pump, which may burn out the motor when the water pump is restarted.
