4.2 Step-by-Step Assembly Tips
- Unpacking: Carefully unpack all components and verify against the package contents list. Inspect all glass panels for damage before proceeding.
- Base Assembly: Begin by assembling the base frame. Ensure all connections are secure.
- Installing Glass Panels: When installing the glass panels, it is often easier to slide the vertical support poles down into place after the glass is positioned, rather than attempting to slide the glass into pre-installed poles. This can simplify the process.
- Top Frame Installation: Place the top frame onto the assembled glass structure. Secure it using the provided 4 metal screws and 4 rubber caps. If you notice a slight gap when placing the lid, ensure all screws are tightened properly; this typically resolves the issue.
- Door Installation: Install the front sliding glass doors into their tracks.
- Security Lock: Attach the double security lock to the front sliding doors to prevent escapes.
- Wire Inlets: Identify the 12 closable inlets on the top lid for routing wires for lighting, heating, or other accessories.

5. Operating Instructions
5.1 Front Sliding Doors
The terrarium features double front opening transparent glass doors. These doors slide horizontally to allow easy access for feeding, cleaning, and decorating the enclosure. Always ensure the doors are fully closed and the security lock is engaged after access to prevent your pet from escaping.

5.2 Top Screen Ventilation
The top of the terrarium is equipped with a full mesh screen, designed to allow optimal air circulation and facilitate the penetration of full spectrum, UVB, and infrared light. This design supports the easy installation of various lighting and heating fixtures directly on top of the mesh or within the vivarium. The screen also features 12 closable holes for convenient wire management.

5.3 Raised Base Design
The terrarium features a raised base, specifically designed to accommodate a substrate heater or heat cable underneath the enclosure. The waterproof bottom can safely hold up to 5.5 inches of water, making it suitable for creating both desert and rainforest habitats. Each terrarium undergoes leak testing to ensure its integrity.

6. Maintenance
- Cleaning: Regularly clean the glass panels with a reptile-safe glass cleaner or warm water and a soft cloth. Avoid harsh chemicals that could harm your pet.
- Substrate Replacement: Follow recommended guidelines for your specific reptile or amphibian regarding substrate replacement frequency.
- Screen Maintenance: Periodically check the top mesh screen for any damage or blockages to ensure proper ventilation. Clean gently with a soft brush if needed.
- Lock Check: Routinely inspect the security lock for proper function to prevent accidental escapes.
- Leak Inspection: Although leak-tested, periodically check the base for any signs of leakage, especially if maintaining a high-humidity environment.
7. Troubleshooting
- Gaps in Top Frame: If a gap appears after assembly, ensure all 4 metal screws securing the top frame are fully tightened.
- Difficulty Sliding Glass Panels: Ensure the tracks are clear of debris. If panels are stiff, a small amount of silicone lubricant (reptile-safe) can be applied to the tracks.
- Missing Parts: If any parts are missing upon delivery, contact Oiibo customer service immediately for assistance.
