To address poor air flow in your Nu-Air Heating System, ensure the HRV is correctly balanced. Inspect and tape all joints. Use proper airflow measuring equipment. Open grills and remove any obstructions in the ducts, hoods, and grills. Clean the filter. If problems persist, consult a professional.
What to do if there is water in the bottom of my Nu-Air NU0103?
To fix water at the bottom of your Nu-Air HRV, check for kinks in the drain lines and ensure proper water drain connections, making sure water drains from the pan. Also, ensure the HRV is level and that the heat exchange core is properly installed.
Why are the humidity levels too high in my Nu-Air Heating System?
If your Nu-Air Heating System's humidity levels are too high, balance the airflow and set the dehumidistat. The causes could be incorrectly balanced HRV air flows, an undersized HRV, high humidity areas not being properly ventilated, or a malfunctioning dehumidistat.
What to do if the outside duct of my Nu-Air NU0103 Heating System has ice build-up?
If you notice ice build-up or condensation on the outside duct of your Nu-Air Heating System, tape all joints and ensure the vapor barrier is completely sealed and insulated around the insulated duct. This is likely due to an improperly installed vapor barrier.
What to do if the dehumidistat is not working in my Nu-Air NU0103?
If your Nu-Air Heating System's dehumidistat isn't working, check the outside wiring for shorts and ensure the wall switch is correctly connected. Verify that the wires are connected to the proper terminals at the HRV. This could be due to an incorrect connection of the outside low voltage wiring between the HRV and the dehumidistat.
Why are the humidity levels too low in my Nu-Air NU0103?
If humidity levels are too low in your Nu-Air Heating System, balance the air flows and increase the dehumidistat setting. It may also be necessary to add humidifiers. This issue can arise from incorrectly balanced HRV air flows or a dehumidistat control set too low.
What causes frosting up of HRV and/or Duct(s) in my Nu-Air NU0103 Heating System?
If the HRV and/or ducts of your Nu-Air Heating System are frosting up, balance the HRV, install dampers, and check the defrost system. Keep in mind that minimal frost build-up is expected on the cores before the unit initiates a defrost cycle. This can be caused by incorrectly balanced HRV air flows or a malfunctioning HRV defrost system.
