Model: 43 Gallon Compost Tumbler Bin
Introduction
This manual provides detailed instructions for the assembly, operation, and maintenance of your Nova Microdermabrasion 43 Gallon Dual Chamber Compost Tumbler Bin. Please read this manual thoroughly before use to ensure proper function and longevity of your composter.
Safety Information
- Always follow general composting safety precautions.
- Keep hands clean and protected from sharp objects during assembly and use.
- Keep the compost tumbler away from children and pets.
- Do not compost meat, dairy products, or diseased plants.
- Always wear gloves when handling compost materials.
Product Features
- Dual Chambers: The composter features two separate compartments, allowing one side to process compost while the other is actively being filled with new organic materials. This design ensures a continuous supply of finished compost. The total capacity is 43 gallons.
- Efficient Aeration System: Designed with aeration holes and deep fins, this system promotes optimal airflow and oxygen circulation within the compost, accelerating decomposition and preventing clumping. The black color of the composter also aids in absorbing UV light, further enhancing the composting process.
- 360° Tumbling Design: The tumbling mechanism eliminates the need for manual digging or turning. Simply rotate the bin to mix the contents, aerate the pile, and distribute moisture evenly, significantly speeding up the composting process. Deep baffles on the eight panels ensure smooth rotation and thorough mixing for even fermentation and faster composting.
- Durable Construction: The main body is constructed from durable, BPA-free PP (polypropylene) material, which is weather-resistant and designed to withstand sunlight without degradation. The robust metal frame features a high-grade coating for corrosion resistance.
- Easy Assembly: The composter is designed for straightforward assembly. All necessary accessories and clearly coded parts are included, along with detailed instructions. Assembly can typically be completed in approximately 15 minutes by following the step-by-step guide.

Operating Instructions
1. Adding Materials
Utilize the dual chambers for efficient composting. Begin by filling one chamber with organic waste. Good materials for composting include:
- "Greens" (Nitrogen-rich): Fruit and vegetable scraps, coffee grounds, tea bags, fresh grass clippings, plant trimmings.
- "Browns" (Carbon-rich): Dried leaves, straw, wood chips, shredded newspaper, cardboard.
Aim for a balance of "greens" and "browns" (roughly 1 part green to 2-3 parts brown by volume) for optimal decomposition. Avoid adding meat, dairy, oily foods, or diseased plants to prevent pests and odors.
2. Tumbling the Composter
After adding materials, close the sliding doors securely. Rotate the composter 5-10 times every 2-3 days. This tumbling action mixes the contents, aerates the pile, and distributes moisture evenly, significantly speeding up the composting process.

3. Moisture Management
The compost mixture should feel like a damp sponge. If it's too dry, add a small amount of water. If it's too wet, add more "brown" materials like shredded paper or dry leaves.
4. Using Dual Chambers
Once the first chamber is full, stop adding new materials to it and allow it to cure. Begin filling the second chamber with fresh scraps. By the time the second chamber is full, the compost in the first chamber should be ready for use.
5. Harvesting Finished Compost
Finished compost will be dark brown, crumbly, and have an earthy smell. To harvest, position a wheelbarrow or tarp beneath the desired chamber, open the sliding door, and rotate the composter to release the finished compost.

Maintenance
- Cleaning: Periodically clean the exterior of the composter with mild soap and water. Ensure aeration holes remain clear of debris.
- Inspection: Regularly inspect the composter for any signs of wear or damage, especially the rotating mechanism and frame.
- Storage: While designed for outdoor use, storing the composter in a sheltered area during extreme weather conditions can extend its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Compost is too wet/smelly | Too many "greens", not enough "browns", or insufficient aeration. | Add more "brown" materials (e.g., dry leaves, shredded paper). Tumble more frequently to increase aeration. |
| Compost is too dry/not breaking down | Too many "browns" or lack of moisture. | Add more "green" materials (e.g., fresh food scraps). Add a small amount of water and tumble. |
| Pests (e.g., flies, rodents) | Adding inappropriate materials (meat, dairy) or exposed food waste. | Ensure all food scraps are buried within the compost pile. Avoid composting meat and dairy. Keep doors securely closed. |
| Slow decomposition | Lack of moisture, aeration, or proper carbon/nitrogen balance. | Adjust moisture content, tumble more often, and ensure a good mix of "greens" and "browns". The black color helps absorb heat, which aids decomposition. |
