Package Contents

Before beginning assembly, ensure all components are present and undamaged. The package typically includes:

• Aluminum frame profiles
• 8mm polycarbonate double-skin panes

Setup and Assembly

Assembly of the BioStar 1500 Cold Frame requires careful attention to detail. While the process is designed to be straightforward, it is recommended to have a second person for assistance, especially during the initial framing. Lay out all parts and familiarize yourself with the components before starting.

1. Frame Assembly: Connect the four main panels (A, B, C, D) using the provided corner braces. Each corner brace is marked (I, II, III, IIII) and corresponds to a specific corner. Ensure the correct brace is used for each connection as indicated in the visual instructions. Secure the panels with bolts and wing nuts. The green caps on the braces help ensure proper alignment.
2. Panel Insertion: Carefully slide the 8mm polycarbonate double-skin panes into the aluminum frame channels. Ensure the "No-Drip" coating side faces inwards to prevent condensation on plants.
3. Window Lid Installation: Attach the three window lids to the top frame. The lids are designed to fit tightly.
4. Ventilator Installation: Install the two adjustable wind-proof ventilators on their designated window lids. This step requires drilling holes for proper attachment.
5. Automatic Opener Installation: Install the automatic window opener on the central window lid. This also requires drilling holes. Follow the specific instructions provided with the automatic opener for correct assembly and attachment to the lid and front panel. The opener is temperature-adjustable.
6. Anchoring: Once assembled, position the cold frame in its desired location. Use the four anchoring pins to secure the frame to the ground or a raised bed. For loose soil, consider additional measures like packing topsoil around the base or using a wooden base for stability.

Operating Instructions

Proper operation of your cold frame ensures optimal plant growth and protection.

• Ventilation: The cold frame features three windows. Two windows have adjustable wind-proof ventilators that can be manually opened or closed to control airflow. The third window is equipped with an automatic opener that reacts to temperature changes, opening when it gets warm and closing when it cools down. This helps maintain a stable internal temperature.
• Condensation Control: The 8mm polycarbonate panes have a unique "No-Drip" coating on the interior surface. This coating prevents condensation from forming and dripping onto your plants, reducing the risk of fungal diseases.
• UV Protection: The panes are UV-resistant, protecting your plants from harmful UV radiation while allowing beneficial light to pass through. This UV resistance also comes with a 10-year guarantee against yellowing of the panes.
• Securing Lids: Use the provided window fixation clips to secure the lids in either a closed position for maximum insulation or an open position for increased ventilation.

Maintenance

Regular maintenance will extend the life and efficiency of your cold frame.

• Cleaning: Clean the polycarbonate panes periodically with mild soap and water using a soft cloth or sponge. Avoid abrasive cleaners or brushes that could scratch the surface. Rinse thoroughly with clean water.
• Frame Inspection: Annually inspect the aluminum frame for any signs of damage or loose fasteners. Tighten any loose bolts or screws. The aluminum frame is designed to be rust-free.
• Automatic Opener Check: Ensure the automatic opener mechanism is clean and moves freely. Lubricate moving parts if necessary, following the opener's specific instructions.
• Anchoring: Periodically check that the anchoring pins are securely in place, especially after strong winds or heavy rainfall.
• Winter Preparation: In areas with heavy snowfall, ensure the cold frame is clear of excessive snow accumulation to prevent stress on the structure. The 8mm panes provide good insulation, but additional insulation (e.g., blankets or straw around the base) can be added during extreme cold.

Troubleshooting

If you encounter issues with your cold frame, consider the following:

• Lids not aligning/fitting properly: Check that the frame was assembled squarely. Ensure the correct corner braces (I, II, III, IIII) were used in their designated positions during assembly.
• Automatic opener not functioning: Verify that the opener was installed correctly and that all parts move freely. Ensure the cylinder is not damaged. The opener is temperature-sensitive; check if the ambient temperature is within its operating range.
• Excessive condensation: Confirm that the "No-Drip" side of the polycarbonate panes is facing inwards. Ensure adequate ventilation is provided, especially during humid conditions.
• Frame instability: Re-check the anchoring pins and ensure they are firmly secured. If placed on uneven ground, level the area or use a stable base.
