**Installation and Maintenance Guide for the Ultra-Clean Workbench**
Before using the ultra-clean workbench, make sure to connect it to a stable power supply and turn it on by pressing the corresponding function button on the control panel. Before starting the machine, thoroughly clean the working area and the outer casing of the clean bench, removing any surface dust. Allow the system to run for 10 minutes to ensure proper operation before beginning your work.
**Maintenance Tips:**
1. **Primary Filter Cleaning:**
It's recommended to remove and clean the primary filter every 3 to 6 months, depending on usage. If left uncleaned for too long, dust buildup can reduce airflow and lower the cleaning efficiency.
2. **Fan Voltage Adjustment:**
If the desired cross-sectional wind speed is not achieved after replacing or cleaning the primary filter, adjust the fan’s working voltage (using the rotation knob) to achieve a uniform airflow. For new workbenches, the initial working voltage should be set between 80V and 90V.
3. **High-Efficiency Filter Replacement:**
After about 18 months of use, if the fan voltage is at its maximum but the ideal wind speed still cannot be reached, it may indicate that the high-efficiency filter is heavily clogged. In such cases, replace the filter promptly. The typical lifespan of a high-efficiency filter is around 18 months.
4. **Proper Filter Installation:**
When replacing the high-efficiency filter, ensure that you use the correct model size as specified by the original manufacturer. Align the arrow indicating the airflow direction and make sure the edges are properly sealed to prevent air leakage.
**Common Faults and Troubleshooting:**
- **Symptom:** Main power switch doesn't close and trips automatically.
**Cause:**
1. Fan motor is stuck or there is a short circuit in the wiring.
**Solution:**
1. Adjust the fan shaft position or replace the impeller and bearings. Check the wiring for damage.
