2. Safety Information
WARNING:
- This greenhouse contains heavy components. Always use appropriate safety gear, such as gloves and safety glasses, when assembling or disassembling the greenhouse.
- Exercise caution during assembly to prevent injury from falling parts or sharp edges.
- Secure the greenhouse firmly to the ground to prevent it from tipping over in windy conditions. Refer to the "Exceptional Stability" section for anchoring methods.
- While polycarbonate panels block UV rays, prolonged exposure inside the greenhouse may still cause eye or skin irritation. Use appropriate sun protection.
- Always follow the manufacturer's instructions for proper assembly, use, and maintenance.
- Keep children and pets away from the assembly area.
3. Assembly Instructions
The CDCASA greenhouse features a modular design with patented Quick Connect technology, significantly reducing assembly time. Two skilled individuals can typically assemble this greenhouse within 4-6 hours. Comprehensive instructions are included in your package, and a video guide may also be available online.
3.1 Before You Begin
- Unpack all components and verify against the parts list provided in your package.
- Ensure you have the necessary tools, including a drill.
- Choose a level and stable location for your greenhouse.
- Note that your product may arrive in multiple packages.
3.2 Quick Connect System
The Quick Connect system utilizes a simple push and locking screw mechanism for fast and secure frame assembly. This technology saves over 50% of the time compared to traditional connecting methods.

3.3 Frame Assembly
Follow the step-by-step instructions provided in your physical manual for assembling the aluminum frame. Pay close attention to the orientation of each piece. Some square-back screws slide into grooves, not holes, which is a key detail for correct assembly.
3.4 Panel Installation
Carefully slide the 4mm twin-wall polycarbonate panels into the designated grooves in the frame. Ensure panels are fully seated. The roof panels and side wall panels are designed to fit securely.
3.5 Exceptional Stability and Anchoring
For enhanced stability and resistance to snow and wind, it is crucial to properly anchor your greenhouse. You have several options:
- Burying Base Feet: The base feet can be buried directly in soil or concrete.
- Securing to a Board: Use matching screws (LD07) to secure the base to a wooden board or foundation.
- Securing to Concrete: Insert BJ05 into BJ04 and then mount into concrete.
- Additional Reinforcement: For areas with high winds (30-40 mph or more), consider adding internal guy wires across the length and width of the structure. This can be done using 1/8" stainless steel cable and turnbuckles attached to the structure in an "X" pattern to add rigidity. Sealing all panels with silicone caulk can also improve wind resistance.

4. Operating Instructions
4.1 Ventilation (Roof Vents)
Your greenhouse is equipped with 4 adjustable roof vents to provide continuous fresh air circulation for your plants. These vents have 5 adjustable angles, allowing you to control airflow and temperature inside the greenhouse.

To adjust the vent, simply lift the arm and secure it at the desired angle. Ensure vents are closed during strong winds or heavy rain to prevent damage.
4.2 Door Operation
The greenhouse features swing doors for easy access. Snap-on door handles are designed to keep the doors securely closed. To open, simply unlatch the handle and swing the door outwards. Ensure the doors are fully closed when not in use to maintain internal climate and prevent pests.

4.3 Rain Gutter System
Rain gutters are integrated on both sides of the greenhouse to effectively drain rain and snow, preventing water accumulation on the roof and directing it away from the base. Regularly check and clear the gutters of debris to ensure proper drainage.

5. Maintenance
- Cleaning: Regularly clean the polycarbonate panels with mild soap and water to maintain light transmission and appearance. Avoid abrasive cleaners or tools that could scratch the panels.
- Frame Inspection: Periodically inspect the aluminum frame for any signs of damage, corrosion, or loose connections. Tighten any screws as needed.
- Panel Integrity: Check panels for any cracks, chips, or signs of yellowing/brittleness. While durable, extreme weather or prolonged exposure can affect panel integrity over time. If panels appear to be slipping out of grooves, consider applying silicone caulk around the edges for a more secure fit.
- Gutter Maintenance: Keep the rain gutters clear of leaves, dirt, and other debris to ensure proper water drainage.
- Vent and Door Mechanisms: Ensure that the roof vents and swing doors operate smoothly. Lubricate hinges if necessary.
