**Installation and Operation**
To begin using the ultra-clean workbench, first connect it to the power supply and press the power button on the control panel. Before turning it on, make sure to clean the work area and the outer casing thoroughly, removing any dust or debris. After cleaning, let the system run for about 10 minutes to ensure optimal performance before starting your work.
**Maintenance Tips**
1. **Primary Filter Cleaning**: It's important to remove and clean the primary air filter regularly based on usage. A recommended cleaning cycle is every 3 to 6 months. If not cleaned frequently, dust buildup can reduce airflow and affect the cleanliness of the environment.
2. **Fan Voltage Adjustment**: If the desired airflow isn’t achieved after replacing or cleaning the primary filter, adjust the fan’s working voltage (using the rotation knob) to reach the ideal wind speed. For new workbenches, the initial voltage should be set between 80V and 90V.
3. **High-Efficiency Filter Replacement**: After 18 months of use, if the fan voltage is at its maximum and the desired wind speed still isn't achieved, this may indicate that the high-efficiency filter is clogged. The typical lifespan of a high-efficiency filter is around 18 months, so it should be replaced when necessary.
4. **Proper Filter Installation**: When replacing the high-efficiency filter, always use the correct model size as specified by the manufacturer. Ensure the arrow on the filter points in the right direction and that the edges are properly sealed to prevent air leakage.
**Common Faults and Solutions**
- **Main Power Switch Trips Automatically**
