Operation steps
1. Equipment inspection and preparation
- Before starting, the equipment should be fully inspected to ensure that all parts are intact and the power wiring is correct.
- Make sure to place it in a well-ventilated environment away from flammable items to avoid potential safety hazards.
- Operators should wear appropriate protective equipment to reduce potential risks of injury.
2. Addition and selection of liquid medium
- Liquid medium must be added to the intelligent thermostatic bath before use, otherwise the heater will be damaged when powered on, and the medium liquid level should be about 30mm lower than the workbench.
- The selection of liquid medium should comply with the following principles:
- When the working temperature is between 5 and 85℃, water is generally used as the liquid medium.
- When the working temperature is between 85 and 95℃, a 15% glycerol aqueous solution can be used as the liquid medium.
- When the working temperature is below 5℃, alcohol or refrigerant is generally used as the liquid medium.
3. Startup and operation
- When starting, it should be carried out in accordance with the prescribed procedures to avoid sudden start or stop to avoid impact on the equipment.
- When setting the temperature parameters of the thermostatic bath, you should strictly follow the experimental or production requirements to avoid setting unreasonable parameters that are too high or too low, so as not to affect the experimental results or damage the equipment.
- During operation, the temperature and other key parameters of the equipment should be monitored in real time, and detailed records should be kept.
4. Stop and shut down
- When stopping, the correct shutdown sequence should also be followed.
- After use, turn off the "circulation", "refrigeration" and "power" switches in sequence.
Safety precautions
1. Power supply and grounding
- The power supply power should be greater than the total power of the instrument, and the power supply must have a good "grounding" device.
- Never plug or unplug the power plug with wet hands, and never operate the instrument with wet hands.
2. Temperature control and monitoring
- If abnormal overheating occurs, the machine should be shut down immediately and cooling measures should be taken. If necessary, contact the manufacturer or professional maintenance personnel for processing.
- If liquid leakage is found, the machine should be shut down immediately and measures should be taken to prevent the leakage from spreading, and relevant personnel should be notified for processing.
3. Personal protection
- When the thermostatic bath is heated, do not touch the liquid medium and high-temperature parts with bare hands to prevent burns.
- When the thermostatic bath is operating at a low temperature, do not touch the liquid medium and low-temperature parts with bare hands to prevent frostbite.
4. Emergency handling
- In case of power failure, cut off the power immediately and notify professionals for repair.
Maintenance
1. Cleaning and maintenance
- Regularly clean and maintain to remove internal dust and dirt to ensure the normal operation of the equipment.
- When cleaning the sink, make sure the equipment is powered off to avoid accidents.
2. Water quality management
- Use deionized or distilled water, and avoid using hard water, as mineral precipitation in hard water may clog pipes and heaters.
- Regularly change the water in the sink to prevent scale accumulation and microbial growth.
3. Parts inspection and replacement
- Regularly check the power cord, plug and heating element of the sink to ensure that they are not damaged or aged.
- Check whether the temperature control system of the water tank is accurate. If there is any deviation, calibrate it in time or contact professionals for repair
4. Anti-corrosion measures
- Avoid putting corrosive chemicals directly into the water tank to avoid damaging the inner wall of the water tank.
- After use, clean the water tank in time and make sure there is no chemical residue.
5. Storage conditions
- When not in use, drain the water in the water tank and wipe it dry with a soft cloth to prevent water accumulation and corrosion.
- Store in a dry and ventilated environment, avoid direct sunlight and moisture.
6. Professional maintenance
- Regularly (such as annually) by professional technicians to carry out comprehensive inspections and maintenance, including replacement of worn parts, calibration of control systems, etc.
The above detailed usage steps, safety precautions and maintenance guidelines can ensure the normal operation of the intelligent precision thermostatic bath and extend its service life. During use, be sure to follow these guidelines to ensure the safety of operators and the performance of the equipment.
