  • Page 35: Troubleshooting

    5. Inspect the cyclone, bin, and connections for leaks. Leaking components or an improperly assembled system can cause excess trim to pass through the cyclone. IF THE DIFFERENTIAL PRESSURE IS NOT WITHIN THE ACCEPTABLE RANGE AFTER CLEANING THE PRIMARY FILTERS, ARRANGE FOR THE T-ZERO TO BE SERVICED.

  • Page 38: Trim To Flower Ratio Is Too High

    11. Make sure the feed conveyor is filled to a consistent height when feeding the T- ZERO. Note: Fluctuations in product feed rate can cause inconsistent flow inside the T-ZERO and will result in low trim quality. 12. Observe the product in the tumbler and make sure there is no surging.

  • Page 39: Product Is Sticking To The Inside Of The Tumbler

    tumbler can hold more product. It will also reduce the airflow to the exit side. This evens out product distribution in the tumbler, allowing the product to exit. 3. If a very dry or low-density product is used, the fan speed can be reduced to allow product to exit the tumbler.
