2. Package Contents and Shipping Information
The Mistmo Outdoor Steel Storage Shed with Frame Floor is shipped in four separate packages (three for the shed and one for the frame floor). These packages may not arrive simultaneously. If you encounter any missing packages, please contact customer support for assistance.

3. Setup and Assembly
Assembly of this storage shed requires careful attention to detail. It is recommended that two to three people work together for efficient and safe assembly. A detailed step-by-step video demonstration is available to assist with the installation process. Please refer to the video in conjunction with the comprehensive instruction manual included in your package.
All metal parts are covered in a protective plastic film. This film should be carefully removed from each panel prior to assembly. Some users find it helpful to remove this film before starting the main assembly steps, as it can be time-consuming.
Assembly Tips:
- Organize all parts and hardware before beginning.
- Follow the numbered steps in the provided manual precisely.
- Do not overtighten screws until instructed, as some flexibility may be needed for alignment.
- Ensure the base frame is level and square before attaching wall panels.

4. Operating Instructions
Door Access and Security:
The shed features generous double door openings designed for easy movement of items in and out. The doors are equipped with a secure locking handle. For optimal security, a padlock (not included) can be used with the integrated locking mechanism.
Ventilation:
Four air vents are integrated into the shed's design to promote air circulation. This helps to reduce condensation and keep the interior fresh and clean, protecting stored items from moisture buildup.
Natural Lighting:
Transparent roof panels are included, which can be installed in designated positions to allow natural light into the shed, brightening the interior without the need for artificial lighting during the day.
Storage Capacity:
This shed offers a large internal capacity suitable for various outdoor storage requirements, including gardening tools, lawn equipment, cushions, and other household items. It can also serve as a chicken coop or general backyard storage solution.

5. Maintenance
Durability and Construction:
The shed is constructed from thicker, robust galvanized steel panels, designed for long-term use and providing exceptional strength and durability against environmental factors.
Weather Resistance:
Built to endure a range of weather conditions, the shed features excellent waterproofing and UV resistance. The sloping roof design prevents rainwater from gathering, ensuring a leak-resistant and rust-proof structure. Regular inspection of the roof and seams is recommended to ensure continued weather protection.
Cleaning:
The materials used are easy to clean. A mild soap and water solution can be used to wipe down exterior and interior surfaces. Avoid abrasive cleaners or tools that could scratch the finish.

6. Troubleshooting
Assembly Difficulties:
- Parts Not Aligning: Ensure all components are correctly oriented according to the manual's diagrams. Sometimes, loosening adjacent screws slightly can allow for minor adjustments to align holes. Retighten all screws once alignment is achieved.
- Dented Panels: If panels arrive with minor dents, gentle pressure from the opposite side can often restore their shape. The metal is designed to be robust yet flexible.
- Missing Hardware/Parts: Double-check all packaging. If components are genuinely missing, refer to the Warranty & Support section to contact customer service.
Structural Concerns:
- Leaks: Verify that all roof panels are correctly overlapped and all screws are tightened. Check for any gaps in seams and apply a silicone sealant if necessary.
- Stability Issues: Ensure the shed is properly anchored to a level surface. Re-check all connections to confirm they are securely fastened.
For any other issues or concerns not covered in this manual, please refer to the Warranty & Support section for contact information.
