What to do about condensation or ice build up in insulated duct to the outside of my Fantech SHR 2004 Fan?
To address condensation or ice buildup in the insulated duct of your Fantech Fan, tape and seal all joints to ensure a complete vapor barrier. Also, tape any holes or tears in the outer duct covering and ensure the vapor barrier is completely sealed.
What to do if Fantech SHR 2004 air is too humid?
If the air from your Fantech Fan is too humid, it might be due to several reasons, including the dehumidistat control being set too high, a sudden change in temperature, storing too much wood inside, a dryer vent exhausting inside, poor air circulation near windows, an out-of-balance HRV, or a closed well-sealed basement door. To address this, reduce the desired level of humidity and use continuous exchange mode. Wait for the outside temperature to stabilize, and consider heating to improve the situation. Store most of your wood outside, arrange an outside vent for the dryer, open curtains or blinds, balance HRV airflows, and open the basement door or install a grill.
How to stop persistent condensation on window with my Fantech Fan?
To fix persistent condensation on your window when using a Fantech Fan, reduce the humidity level and use continuous exchange mode. Open curtains or blinds to improve air circulation. If the problem continues, have a contractor balance the HRV.
How to improve poor air flows in my Fantech SHR 2004?
To improve poor air flows with your Fantech Fan, begin by cleaning the exterior hoods or vents and removing and cleaning the filter and core. Ensure indoor grilles are open and not blocked. Have an electrician check the power supply voltage. Check the duct installation and increase the HRV speed. If the issue persists, have a contractor balance HRV airflows or reconnect ducting.
What to do if the air is too humid with my Fantech Fan?
To address air that's too humid, try reducing the humidity level setting and use continuous exchange mode on your Fantech Fan. Also, ensure your dryer vent exhausts outside, store wood for heating outdoors, and open curtains or blinds to improve air circulation. If you have a well-sealed basement door, open it or install a grill. If the issue persists, a contractor should check the defrost damper, as a failed damper system might be stuck in recirculation mode, or balance HRV airflows.
How to fix Condensation or Ice Build Up in Insulated Duct to the Outside in Fantech Fan?
To address condensation or ice build-up in the insulated duct to the outside of your Fantech Fan, tape and seal all joints if there is an incomplete vapor barrier around the insulated duct. Also, tape any holes or tears made in the outer duct covering and ensure that the vapor barrier is completely sealed if there is a hole or tear in the outer duct covering.
What to do if Fantech SHR 2004 Fan air is too dry?
If the air is too dry when using your Fantech Fan, increase the desired level of humidity if the dehumidistat control is set too low. Also, change the ventilation mode from continuous mode to standby.
How to fix HRV and/or Ducts frosting up in Fantech SHR 2004 Fan?
If your Fantech Fan's HRV and/or ducts are frosting up, consider these solutions: * Have an HVAC contractor balance the HRV airflows if the HRV air flows are improperly balanced. * Note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions, if there is a malfunction of the HRV defrost system.
What to do if Fantech SHR 2004 Fan has persistent condensation on window?
If you notice persistent condensation on windows when using your Fantech Fan, consider the following: * Reduce the desired level of humidity, if there is an improper adjustment of the dehumidistat control, and combine this step with the use of continuous exchange mode. * Have a contractor balance the HRV if the HRV is out of balance. * Open curtains or blinds to improve air circulation near windows.
Why is my Fantech Fan supply air feels cold?
If the supply air from your Fantech Fan feels cold, it could be due to the following reasons: * The location of supply grilles may be causing airflow to irritate occupants. Relocate the grilles high on the walls or under the baseboards, and install ceiling-mounted diffusers or grilles to avoid directly spilling supply air on occupants. You can also turn down the HRV supply speed. A small duct heater (1kW) could be used to temper the supply air. Ensure that furniture placement or closed doors are not restricting air movement. * If the outdoor temperature is extremely cold, and supply air is ducted into the furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.
