3. Safety Information
- Keep away from children and pets to prevent accidental damage or injury.
- Do not leave the zipper door or mesh side windows open unattended, especially during adverse weather conditions such as strong winds or heavy rain.
- Avoid prolonged exposure to direct, intense sunlight to prevent premature fabric degradation and extend the lifespan of the cover.
4. Setup and Installation
This replacement cover is designed for easy assembly without the need for special tools. Please ensure your existing Ohuhu greenhouse frame (models Y21-80401-13, Y21-80400-36, Y21-80401-17) is fully assembled and stable before installing the new cover.
- Carefully unfold the replacement cover, ensuring it is free of twists or tangles.
- Drape the cover over the greenhouse frame, aligning the peaked top and sides.
- Secure the cover to the frame using any integrated ties, straps, or fasteners provided with the cover or the original frame.
- Zip up the entry door and ensure all mesh windows are properly closed or rolled up as desired.
- Utilize the ground seal skirt by placing weights (e.g., bricks, stones) on it to prevent wind uplift and improve insulation.

5. Operation
- Ventilation: Use the roll-up zipper entry door and mesh side windows to regulate airflow and temperature inside the greenhouse. Open them during warmer periods to prevent overheating and close them during cooler periods or at night to retain warmth.
- Temperature Regulation: In cold weather, the cover helps maintain a warmer environment. For additional warmth during very cold nights, placing containers of warm water inside can help increase the internal temperature by approximately 8-10 degrees Fahrenheit.

- Cleaning: Clean the polyethylene fabric periodically with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the material.
- Inspection: Regularly inspect the cover for any tears, punctures, or signs of wear. Promptly repair small tears with appropriate repair tape to prevent them from enlarging.
- Storage: If disassembling the greenhouse for seasonal storage, clean and dry the cover thoroughly before folding. Store it in a cool, dry place away from direct sunlight to extend its lifespan.
7. Troubleshooting
