Setup and Assembly
The SQUEEZE master compost bin is designed for quick assembly, typically within 20 minutes. Follow these steps:
- Assemble the stand frame according to the diagrams provided in the separate assembly guide. Ensure all connections are secure.
- Join the two spherical compost bin halves. Pay attention to the alignment arrows to ensure proper fit and door functionality.
- Install the door panel. The stainless steel hinges are designed to help secure the door and prevent it from falling off during rotation.
- Attach the liquid collector and ensure the drain plug is in the desired position (open and down for liquid collection during composting).
- Place the assembled spherical bin onto the stand frame, ensuring it rotates freely.

Operating Instructions
Adding Materials
Open the large access door to add your composting materials. The wide opening allows for easy addition of kitchen scraps, yard waste, and other organic matter, even with a shovel. Ensure a balanced mix of "greens" (nitrogen-rich, e.g., food scraps, grass clippings) and "browns" (carbon-rich, e.g., dry leaves, wood chips) for optimal composting.

Tumbling and Aeration
To mix and aerate your compost, rotate the spherical bin 360 degrees once every few days. This ensures even decomposition and faster composting. The design allows for easy rotation, even when full.

Liquid Collection (Compost Tea)
The compost bin is equipped with an original liquid collector at the bottom. This allows nutrient-rich liquid, often called "compost tea," to flow out during the fermentation process. Keep the liquid collector's drain plug open and facing downwards to collect this valuable fertilizer for your plants.

Maintenance
- Regular Cleaning: Periodically clean the exterior of the compost bin with mild soap and water.
- Drain Plug: Ensure the drain plug is clear of debris to allow proper liquid flow.
- Inspection: Regularly inspect the bin and stand for any signs of wear or damage. Tighten any loose screws on the stand.
- Material Balance: Maintain a good balance of green and brown materials to prevent odors and promote efficient decomposition.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door falls off during rotation | Door not securely latched; improper assembly alignment; excessive weight. | Ensure the door is firmly latched before rotating. Verify assembly alignment as per instructions. Avoid overfilling the composter. |
| Compost is too wet/slimy | Too many "greens" or not enough "browns"; insufficient aeration. | Add more "brown" materials (e.g., dry leaves, shredded paper). Increase frequency of tumbling. |
| Compost is too dry/slow to decompose | Too many "browns" or not enough "greens"; lack of moisture. | Add more "green" materials (e.g., food scraps, grass clippings). Lightly moisten the contents if they feel dry. |
| Unpleasant odors | Lack of oxygen; too much nitrogen (greens); anaerobic conditions. | Increase tumbling frequency for better aeration. Add more "brown" materials to balance the mix. |
