TEC Air Flow Method User manual

  • Hello! I've reviewed the user manual for the TEC Minneapolis Duct Blaster. This document provides a guide on using pressure matching to measure air flow. It covers steps from fan operation to using a two-channel manometer. I'm here to answer your questions about this product and its usage.
  • What is the first step in the process?
    What should be recorded after operating the fan?
    What should be installed?
    What should I record once the pressure is matched?

heat or cool.
2. Record the supply static
pressure.
3. Remove filter and install
