Introduction
This manual provides instructions for the assembly, operation, maintenance, and troubleshooting of your Outsunny Walk-in Tunnel Greenhouse, Model 845-611WT. This greenhouse is designed to extend your growing season and protect plants from adverse weather conditions.
Important Safety Information:
- Be cautious of sharp edges during assembly and use.
- Handle heavy components with care.
- Properly anchor the greenhouse to prevent damage or injury from wind.
- Always follow the manufacturer's instructions for safe installation, anchoring, and ventilation.
Setup Instructions
Assembly typically requires 1-2 people. Ensure all parts are present before beginning.
- Unpack and Verify Components: Carefully unpack all components and compare them against the parts list provided in your packaging. Ensure no parts are missing or damaged.
- Assemble the Base Frame: Connect the straight galvanized steel pipes to form the rectangular base of the greenhouse. Use the provided connectors and bolts. Refer to the diagram for correct orientation.

- Construct the Arch Frame: Attach the curved steel pipes to the base frame, forming the arched structure. Ensure all connections are secure. The structure includes seven crossbars and two diagonal braces for stability.
- Install the PE Cover: Drape the anti-tear PE cover over the assembled steel frame. Carefully align the cover, ensuring the zippered door and mesh windows are correctly positioned. Secure the cover to the frame as per the instructions in your packaging.
- Secure the Greenhouse: For optimal stability, bury the 15cm extended edges of the PE cover deep into the soil. Additionally, use the provided wind ropes and ground nails to firmly fix the greenhouse to the ground. This is crucial for stability against wind and rain.

Operating Instructions
- Access and Ventilation: The greenhouse features large, zippered roll-up doors for easy access. Roll-up mesh windows are provided for cross-ventilation and to deter pests. Adjust these openings as needed to control internal temperature and humidity.

- Temperature Control: Monitor the internal temperature. On warm days, open doors and windows to prevent overheating. On cooler days, keep them closed to retain heat. The 140 GSM PE cover is designed for heat preservation while allowing 85% of sunlight to pass through.
Maintenance
- Regular Cleaning: Periodically clean the PE cover with mild soap and water to ensure maximum light transmission. Avoid abrasive cleaners.
- Frame Inspection: Regularly check the galvanized steel frame for any signs of rust, damage, or loose connections. Tighten bolts as necessary.
- Cover Inspection: Inspect the PE cover for tears or punctures. Small damages can be repaired with appropriate greenhouse repair tape to maintain its protective qualities. The cover features a reinforcement grid to prevent tearing.

- Anchoring Check: After strong winds or heavy rain, verify that the greenhouse remains securely anchored to the ground. Re-bury edges or re-tighten ropes if needed.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Greenhouse unstable in wind | Insufficient anchoring; loose frame connections. | Ensure extended edges are buried and wind ropes are tightly secured with ground stakes. Check and tighten all frame bolts. |
| Excessive heat inside | Inadequate ventilation. | Open zippered doors and roll-up mesh windows to increase airflow. |
| Water pooling on cover | Cover not taut; frame sagging. | Ensure the cover is stretched tightly over the frame. Check frame connections for any looseness or damage. The arch shape is designed to prevent sagging. |
| Pests entering greenhouse | Mesh windows or doors not fully closed. | Ensure all zippered doors are closed and mesh windows are properly secured when not in use for ventilation. |
