3. Setup and Installation
The ACMER C4 Air Assist is designed for straightforward installation. It supports two primary assembly methods to ensure compatibility with a wide range of laser modules.
3.1 Assembly Methods
The kit includes components for two different installation types:
- U-clip Method: Suitable for laser modules with dimensions of 40mm x 40mm.
- Nozzle Method: Designed for laser modules with lenses having an outer diameter of 16mm.

3.2 General Installation Steps
- Select the appropriate assembly method (U-clip or nozzle) based on your laser module's specifications.
- Attach the chosen air assist component to your laser module securely.
- Connect one end of the air pipe to the air assist component on the laser module.
- Connect the other end of the air pipe to the ACMER C4 Air Purifier. Ensure a tight fit to prevent air leaks.
- Connect the power cable to the air purifier and then to a suitable power outlet.
- Ensure all connections are secure before operating the laser engraver.
3.3 Compatibility
The ACMER C4 Air Assist Pump Kit is compatible with a wide range of laser engravers, including ACMER P1 and ACMER P2 models, as well as many other brands. No additional modifications are typically needed for integration.

4. Operating Instructions
The ACMER C4 Air Assist features an adjustable airflow to suit different cutting and engraving needs.
4.1 Powering On/Off
To power on the air assist, plug the power cable into an electrical outlet. The unit will begin operating. To power off, unplug the unit from the outlet.
4.2 Adjusting Airflow
The air assist pump features a control dial to adjust the airflow volume. Rotate the dial to increase or decrease the air output, up to a maximum of 30L/min. Adjust the airflow based on the material being processed and the desired cutting or engraving effect. Higher airflow is generally beneficial for thicker materials or to minimize charring.

5. Maintenance
Regular maintenance ensures optimal performance and longevity of your ACMER C4 Air Assist Pump Kit.
5.1 General Cleaning
The air assist significantly reduces smoke and dust buildup during laser operations, which helps keep your workspace and materials cleaner. Periodically inspect the air pipe and nozzle for any obstructions or debris. Clean them gently with a soft cloth or compressed air if necessary.
The pre-filters included in the package help maintain air quality. Replace them as needed to ensure efficient operation and prevent dust from entering the pump.

6. Troubleshooting
If you encounter issues with your ACMER C4 Air Assist Pump Kit, please refer to the following common troubleshooting steps:
- No Airflow: Ensure the power cable is securely plugged in and the unit is receiving power. Check the air pipe for any kinks or blockages. Verify that the airflow control dial is not set to minimum.
- Weak Airflow: Check for any leaks in the air pipe connections. Ensure the pre-filters are clean and not clogged. Increase the airflow using the control dial.
- Unusual Noise: While the unit operates quietly (less than 40dB), excessive or unusual noise may indicate an issue. Ensure the unit is placed on a stable, flat surface. Check for any loose components or foreign objects.
- Poor Cutting/Engraving Quality: Ensure the air assist nozzle is properly aligned with the laser's focal point. Adjust the airflow as needed for the specific material and laser settings.
If problems persist after attempting these steps, please contact customer support.
