What to do about condensation or ice build up in insulated duct to the outside of my Fantech SHR 1504 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.
Why is the air from my Fantech SHR 1504 too dry?
The air from your Fantech Fan may be too dry if the dehumidistat control is set too low or the HRV is out of balance. You can increase the desired level of humidity and change the ventilation mode from continuous to standby. It is also recommended to have a contractor balance the HRV airflows.
What to do if Fantech SHR 1504 Fan has poor air flows?
If your Fantech Fan has poor air flows, you can try the following: * Clean exterior hoods or vents if the 1/4" (6mm) mesh on the outside hoods is plugged. * Remove and clean the filter if filters are plugged. * Remove and clean the core if it is obstructed. * Check and open indoor grilles if they are closed or blocked. Also, ensure that an electrician checks the supply voltage if there is an inadequate power supply at the site and check duct installation if ductwork is restricting airflow. Increase the speed of the HRV if there is an improper speed control setting. If the HRV airflow is improperly balanced or ducting has fallen down or been disconnected from the HRV, have a contractor address these issues.
Why is my Fantech SHR 1504 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.
What to do if Fantech SHR 1504 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.
How to fix HRV and/or Ducts frosting up in Fantech SHR 1504?
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 Fan HRV and/or Ducts frosting up?
If your Fantech Fan's HRV and/or ducts are frosting up, it could be due to improperly balanced HRV air flows, have an HVAC contractor balance the HRV airflow. Note that minimal frost build-up is expected on cores before unit initiates defrost cycle functions.
Why are my Fantech SHR 1504's HRV and/or ducts frosting up?
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.
Why does supply air feel cold from my Fantech SHR 1504?
If the supply air from your Fantech Fan feels cold, reposition the supply grilles high on the walls or under the baseboards, and install ceiling-mounted diffusers to avoid direct airflow on occupants. Reduce the HRV supply speed. If supply air is ducted into the furnace return, run the furnace fan continuously. Also, ensure furniture or closed doors aren't restricting air movement.
How to improve poor air flows in my Fantech SHR 1504 Fan?
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.
