1. Safety Information
Please read and understand all safety instructions before assembly and use. Failure to follow these instructions may result in injury or damage to the product.
- Secure Installation: Always secure the greenhouse base to the ground using expansion screws or other appropriate anchoring methods to prevent wind damage.
- Weather Precautions: During severe weather conditions (e.g., strong winds, heavy snow), it is recommended to remove any valuable items from inside the greenhouse to avoid potential property loss.
- Water Protection: Apply glass glue to the connections between the polycarbonate panels and the frame for enhanced water protection and sealing.
- UV Protection: The double-wall polycarbonate boards offer 4mm UV protection, blocking 99% of UV radiation to protect plants. However, prolonged direct exposure to sunlight inside the greenhouse should be monitored for sensitive plants.
- Assembly: This product is delivered in multiple packages and may not arrive simultaneously. Ensure all packages are received before beginning assembly.
2. Package Contents
Please verify that all components are present and undamaged before starting assembly. Refer to the detailed packing list included in your product packaging.
Typical components include:
- Aluminum alloy frame components
- Double-wall polycarbonate panels
- Sliding door assembly
- Adjustable skylight windows
- Fasteners and hardware (screws, nuts, bolts, expansion screws)
- Reinforced rods and diagonal rod fixations
- Instruction manual
3. Setup and Assembly
Assembly requires careful attention to detail. It is recommended to have at least two people for installation.
3.1 Foundation Preparation
Prepare a level and stable foundation for the greenhouse. For enhanced stability and wind resistance, consider placing the bottom frame in a pre-dug trench.
3.2 Frame Assembly
Assemble the aluminum alloy frame according to the diagrams in the included manual. Ensure all connections are secure. The frame features reinforced rods on the sides and diagonal rod fixation for enhanced sturdiness.

3.3 Panel Installation
Install the double-wall polycarbonate panels into the frame. Ensure they are correctly seated and secured. For optimal waterproofing, apply glass adhesive to seal the joints where the PC panels meet the frame.

3.4 Securing the Greenhouse
After assembling the frame and panels, fix the base to the ground with expansion screws in the pre-drilled holes. Additional measures for wind resistance include driving stakes into the four corners (not included) and securing both sides of the conservatory using wire locks (not included).

5. Maintenance
- Regular Cleaning: Clean the polycarbonate panels periodically with mild soap and water to maintain light transmission and appearance. Avoid abrasive cleaners.
- Seal Integrity: Regularly inspect the glass glue seals between panels and the frame. Reapply if any signs of cracking or degradation are observed to ensure water protection.
- Frame Inspection: Check the aluminum frame for any loose fasteners or signs of corrosion. Tighten fasteners as needed.
- Ventilation System: Ensure the adjustable skylights operate smoothly and are free from obstructions.
- Drainage: Keep the side drain tanks clear of debris to ensure effective water drainage.
6. Troubleshooting
- Panels Blowing Away: Ensure the greenhouse base is securely anchored to the ground using all provided expansion screws and consider additional anchoring methods like ground stakes or wire locks, especially in windy areas.
- Water Leakage: Check all panel-to-frame joints. Apply or reapply glass glue to ensure a watertight seal. Verify that the side drain tanks are not blocked.
- Difficulty with Sliding Door: Inspect the sliding track for debris or obstructions. Lubricate the track if necessary. Ensure the door is properly aligned.
- Poor Ventilation: Adjust the skylight windows to increase airflow. Ensure no plants or objects are blocking the vents.
