- Step 3: Assemble Small Support Beams. Attach any smaller crossbeams or support elements as indicated in the diagram.
- Step 4: Install the Cover and Secure It. Carefully drape the PE canopy cover over the assembled frame. Ensure it is centered and aligned.
- Step 5: Install Steel Pipes at Four Corners. Attach the vertical corner posts to the base of the top frame.

Operating Instructions
Roll-Up Zipper Doors
The carport features two roll-up zipper doors at each end. To open, unzip the door completely and roll it upwards, securing it with the attached straps. This provides easy drive-through access for vehicles and enhances ventilation.
Mesh Windows
The four side mesh windows can be rolled up to allow for additional air circulation, preventing heat buildup inside the canopy, especially during warmer periods. Secure them in the rolled-up position using the integrated fasteners.

Solar Light and Light Strip
The included solar light and light strip are designed to provide illumination during nighttime. Ensure the solar panel for the light is positioned to receive adequate sunlight during the day for optimal charging. The light strip can be draped along the side for ambient lighting.

Maintenance
- Regular Inspection: Periodically check all frame connections, ropes, straps, and ground anchors to ensure they are secure and in good condition. Tighten any loose connections.
- Canopy Cleaning: Clean the PE canopy with mild soap and water. Avoid harsh chemicals or abrasive brushes that could damage the material or its protective coating. Rinse thoroughly and allow to air dry.
- Weather Preparedness: In anticipation of severe weather conditions (heavy winds, snow, or ice), it is recommended to temporarily dismantle the carport or take extra precautions to secure it. Clear any accumulated snow from the roof to prevent structural damage.
- Zipper Care: Keep zippers clean and lubricated with a silicone-based spray to ensure smooth operation and prevent sticking.

Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Carport instability in wind | Insufficient anchoring; loose connections. | Ensure all wind ropes, binding straps, and sandbags are properly installed and taut. Verify all frame connections are tight. Consider additional anchoring in very windy areas. |
| Difficulty during assembly | Parts misalignment; incorrect order of steps; insufficient manpower. | Refer to the installation steps and diagrams carefully. Ensure all parts are correctly oriented before tightening. Work with at least 2-3 people. |
| Water pooling on canopy | Canopy not taut enough; improper frame assembly. | Adjust the canopy to ensure it is stretched tightly over the frame. Recheck frame assembly to ensure correct angles and support. |
| Zippers sticking or difficult to operate | Dirt/debris in zipper teeth; lack of lubrication. | Clean zipper teeth with a small brush. Apply a silicone-based lubricant to the zipper teeth and pull tab. |
