3. Configuración y montaje

Assembly typically requires two or more adults. Follow the steps below for proper installation.

3.1. Desembalaje e identificación de componentes

Carefully unpack all components and verify against the parts list (not provided in this manual, refer to your product packaging). Ensure all frame pieces, connectors, the PE cover, doors, windows, and anchoring hardware are present.

3.2. Montaje del marco

Begin by assembling the base frame on your chosen level site. Connect the galvanized steel rods using the provided optimized screws and solid connectors. Ensure all connections are firm to establish a stable foundation.

3.3. Instalación de la cubierta

Once the frame is fully assembled and stable, carefully drape the PE material plastic cover over the structure. Ensure the cover is centered and evenly distributed. The cover is designed to be tough, durable, and 100% waterproof, transmitting 85% of sunlight while blocking harmful UV rays.

Secure the cover to the frame using the provided buckles and fixed drawstrings with ground nails. The overlong PE cover should be used for soil coverage to enhance sealing and wind resistance. Ensure the zippered doors are properly aligned and functional.

3.4. Anclaje

The ground frame adopts U-shaped piles to effectively grasp the ground and reduce wind resistance. Utilize all provided anchoring hardware to firmly secure the greenhouse to the ground. Proper anchoring is critical for stability, especially in windy conditions.
