1、 External cleaning and protection

1. Shell cleaning
   • Regularly use a clean and damp cloth to wipe the equipment casing, avoiding the use of cleaning agents containing acidic or alkaline components to prevent surface corrosion.
   • When stopping use, cover the equipment with a plastic cover and place moisture-proof silicone inside the cover to prevent the lamp chamber from getting damp or the reflective mirror from getting moldy.
2. Power and Circuit Inspection
   • Check the power cord, plug, and control panel indicator lights monthly to ensure that the connections are secure and not loose.
   • In environments with significant power fluctuations, use an AC regulated power supply of 500W or higher to avoid voltage instability and equipment damage.

2、 Internal component maintenance

1. Filter cleaning and replacement
   • Check the smoothness of the filter screen every month and clean any attached dirt; Replace the filter every six months to ensure compatibility and filtration efficiency.
   • Use mild cleaning agents and soft brushes during cleaning to avoid corrosive chemicals.
2. Pump and pipeline maintenance
   • Check the operation status of the water pump every month to ensure no abnormal noise or vibration; When lubricating bearings, use the manufacturer's recommended grease.
   • Regularly clean the pipeline to prevent the accumulation of scale and dirt; Check if the pipeline connections are securely fastened to prevent water leakage.
3. Maintenance of sensors and optical components
   • Regularly check the performance of the sensor and replace it promptly if any damage or malfunction is found.
   • When cleaning optical components such as light sources and probes, use a soft cloth to wipe and avoid direct rinsing or the use of chemical cleaning agents.

3、 Performance calibration and testing

1. periodic calibration
   • Regularly perform performance calibration based on device usage and manufacturer recommendations to ensure accuracy of measurement results.
   • Select appropriate calibration solution and curve before calibration, record calibration data, and promptly correct the curve.
2. functional testing
   • Perform monthly functional testing to check indicators such as rinsing effectiveness and flow stability.
   • If any abnormalities are found, adjust or repair immediately to avoid affecting the experimental data.

4、 Safety operation standards

1. Waterproof and moisture-proof
   • Ensure that the electrical part has good waterproof measures, such as using waterproof covers to protect electrical components.
   • Avoid short circuits caused by humid environments and regularly check whether the equipment is damp inside.
2. Follow the operating procedures
   • Strictly follow the instructions to operate the equipment and avoid overloading or unauthorized operation.
   • Regularly train operators to ensure familiarity with equipment processes and emergency response measures.

5、 Record management and long-term maintenance

1. Usage record
   • Detailed records of equipment usage, including cleaning frequency, maintenance items, replacement of parts, and other information.
   • Establish equipment files for subsequent management and analysis of fault causes.
2. Long term storage and transportation
   • When not in use for a long time, turn on the device 1-2 times a week for about half an hour each time to prevent aging.
   • Handle with care during transportation to avoid collisions and vibrations; Store in a dry and ventilated place, away from high temperatures and direct sunlight.
