Why is my Envirco Water Filtration System unit not running?
- A
  Abigail JeffersonAug 2, 2025
  The Envirco Water Filtration System might not be running due to several reasons. It could be due to no power; confirm the primary voltage. It could also be due to bad electronics such as a faulty switch, transformer, or board; check these electrical components for functionality. A faulty motor harness could also be the reason; if voltage is found at the control board but not at the motor, replace the motor harness. The motor itself might be faulty; if voltages are correct on the board and motor, but the motor still does not run, reference the troubleshooting section for mechanical issues and perform the steps. A mechanical issue could also be the cause. In addition, network control issues could be the reason; refer to the Unit Not Running troubleshooting section.

What to do if my Envirco Water Filtration System has low airflow?
- C
  Caleb PotterAug 6, 2025
  If your Envirco Water Filtration System has low airflow, check the filter media. The pre-filter can be cleaned or replaced, and the HEPA/ULPA media may need to be replaced. Verify the air supply is adequate to provide the airflow required; it is recommended to start fan filter units before air handlers. Also, check that the unit is running and reference the troubleshooting for unit not running and mechanical issues. Increase the speed control setting to the fan filter units. Finally, verify there are no environmental restrictions.

  Amy JacksonAug 14, 2025
  High airflow in your Envirco Water Filtration System can be caused by an air supply issue. Verify that the air supply is adequate to provide the airflow required and recommend starting fan filter units before air handlers. It can also be caused by a high-speed setting; decrease the speed control setting to the fan filter units.

What to do if the indicator light is not on for my Envirco Water Filtration System?
- A
  anthony11Aug 19, 2025
  If the indicator light is not on for your Envirco Water Filtration System, it may be due to no power; if there is an issue with the electrical components, the indicator lights will not function. It could also be due to a non-working light; it is recommended to unscrew the bezel, take out the bulb, turn it 180 degrees, and reinsert the bulb. Another reason could be the pressure switch closure; the pressure switch must be adjusted when first installed to work for that application’s specific conditions.

What causes a leaking filter in my Envirco Water Filtration System?
- K
  Katherine YoungAug 23, 2025
  A leaking filter in your Envirco Water Filtration System can be caused by a damaged filter; inspect the filter for any physical damage before installing it in the ceiling. It can also be caused by improper installation or bypass; refer to TN1012 to help determine if the filter is leaking or if there is bypass coming from another location.

Why is my Envirco Water Filtration System acting erratically or unable to balance?
- A
  ashley84Aug 27, 2025
  If your Envirco Water Filtration System is acting erratically or is unable to balance, it could be due to an incorrect motor program. Constant volume programming available to the MAC10 IQ is incompatible with ducted, pressurized air applications for use in series with CAV or VAV devices. Also, providing too much or too little air to the fan filter units can cause issues.
