Setup and Assembly
Follow the illustrated guide provided with your product for detailed step-by-step instructions. The following points are crucial for a stable and durable assembly:
- Frame Assembly: Construct the galvanized metal frame according to the diagrams. Ensure all tubes are correctly connected and secured. The frame features oblique reinforcements, a front crossbar, and central tubes for enhanced stability. The tubes are 25mm in diameter with a 0.5mm thickness for strength.
- Cover Installation: Carefully drape the high-density PE cover over the assembled frame. The cover has a 25 cm extension designed for easy installation and ground anchoring.
- Ground Anchoring: Bury the 15 cm extended edge of the PE cover deeply into the soil to prevent wind from lifting the greenhouse.
- Secure with Ropes and Stakes: Use the provided tie-down ropes and spiral ground stakes to firmly fix the greenhouse to the ground. Ensure the ropes are taut.
- Window and Door Attachment: Attach the roll-up mesh windows and the zippered door. Use the attachment balls to connect the cover to the frame where necessary. Apply the adhesive tape to cover any exposed screws on the frame to prevent damage to the cover.

Operating Instructions
The Outsunny Tunnel Greenhouse is designed for optimal plant growth. Proper operation involves managing ventilation and access.
- Ventilation: The greenhouse features 8 roll-up side windows with mosquito nets and tie-down cords. Roll up the windows to allow for maximum air circulation and temperature regulation, especially on warm days. The mosquito nets prevent pests from entering while maintaining airflow.
- Access: The roll-up zippered door provides easy access for tending to your plants, watering, and harvesting. Roll it up and secure it with the provided ties when entering or exiting, or for extended ventilation.
- Climate Control: Adjust the windows and door based on external weather conditions to maintain an ideal internal environment for your plants. Close them during colder periods or strong winds to protect plants.

Maintenance
- Cleaning: Regularly clean the PE cover with mild soap and water to remove dirt and debris, ensuring maximum light penetration. Avoid abrasive cleaners.
- Frame Inspection: Periodically check the galvanized metal frame for any signs of rust, damage, or loose connections. Tighten any loose bolts or connections.
- Cover Inspection: Inspect the PE cover for tears or punctures. Small tears can be repaired with appropriate greenhouse repair tape to prevent them from enlarging.
- Anchoring Check: Ensure the ground stakes and tie-down ropes remain secure, especially after strong winds or heavy rain. Re-tension ropes if necessary.
- Winter Storage: In regions with heavy snowfall or extreme winter conditions, it is recommended to disassemble the greenhouse and store the components in a dry, protected area to prolong its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Greenhouse unstable or swaying in wind. | Insufficient ground anchoring; cover not buried; loose ropes. | Ensure the 15 cm extended edge of the cover is deeply buried. Verify all spiral ground stakes are firmly in place and tie-down ropes are taut. Check frame connections. |
| Water pooling inside. | Improper cover installation; tears in cover. | Ensure the cover is properly stretched and secured over the frame. Inspect the cover for any tears and repair them promptly. |
| Difficulty rolling up windows/door. | Zippers or fabric snagged; debris in tracks. | Clear any debris from zippers or tracks. Ensure fabric is not caught. Apply a silicone-based lubricant to zippers if needed. |
| Frame components do not fit. | Incorrect part orientation; manufacturing defect. | Double-check the assembly guide for correct part orientation. If parts are genuinely defective, contact customer support. |
