What causes HRV and/or ducts frosting up in Fantech SHR 3005R Fan?
If your Fantech Fan's HRV and/or ducts are frosting up, have an HVAC contractor balance the HRV airflows. Note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions.
How to prevent condensation or ice build up in insulated duct to the outside of Fantech SHR 3005R?
If you notice condensation or ice building up in the insulated duct to the outside of your Fantech Fan, make sure to tape and seal all joints to ensure a complete vapor barrier around the insulated duct. Also, tape any holes or tears in the outer duct covering and ensure the vapor barrier is completely sealed.
How to fix HRV out of balance in Fantech SHR 3005R Fan?
To address an out-of-balance HRV in your Fantech Fan, have a contractor balance HRV airfolws.
What does it mean if the LED is flashing on my Fantech SHR 3005R Fan?
If the LED on your Fantech Fan is flashing, make sure the unit is plugged in. If it is, the transformer may need replacing.
What to do if Fantech Fan air is too humid?
If the air is too humid when using your Fantech Fan, here are some potential solutions: * Reduce the desired level of humidity if the dehumidistat control is set too high and combine this with the use of continuous exchange mode. * If there is a sudden change in temperature, wait until the outside temperature stabilizes (especially in winter); heating may also improve the situation. * Store the majority of your wood outside, as even dried wood contains a significant amount of water. * Ensure the dryer vent is exhausting outside. * Open curtains or blinds to improve air circulation near windows. * Open a well-sealed basement door, or install a grill on it. * Check the defrost damper. If a failed damper system may be stuck in recirculation mode, have a contractor verify the da...
