**Safety Precautions:**
1. Always ensure the unit is properly grounded before use.
2. Never turn on the power without filling the water bath with water to avoid damaging the heating element.
3. Avoid opening the right side panel unless necessary for maintenance or troubleshooting.
**Maintenance and Repair Tips:**
1. Always switch off the power after use.
2. Keep the interior and exterior of the water bath clean at all times.
3. If the indicator light does not illuminate, first unplug the device, remove the right panel, and check the fuse or bulb. Replace them with the same specifications if damaged.
4. In case of temperature control failure, it may be due to a faulty sensor. Replacing the sensor should restore normal function.
**Common Faults and Solutions:**
1. **Display works normally, but no heating occurs:**
- Turn on the power and adjust the set temperature higher than the current reading.
- Check if the temperature controller has an output signal.
- Measure the voltage input to the heating element. If there's no voltage, the relay might be faulty. If the controller doesn’t show output, consider replacing it.
2. **Temperature controller shows LLL or 999 (varies by model):**
- This usually indicates a problem with the temperature sensor. Replace the sensor if necessary.
3. **Temperature control issues or damp sensor:**
- Clean the water bath thoroughly after each use. Remove any debris and dry the surfaces.
- Ensure the inner surface is free from moisture and the outer casing remains clean and dust-free.
- Always ground the unit properly and prevent water from entering the control box.
- Never operate the water bath with low water levels, as this can damage the heating elements.
- Perform monthly inspections and keep a maintenance log.
