What to do if Direct Air PHRV 140 has poor air flows?
If your Direct Air Fan has poor air flows, you can try the following: * Clean exterior hoods or vents. * Remove and clean the filter. * Remove and clean the core. * Check and open grilles. * Have an electrician check the supply voltage at the house. * Check duct installation. * Increase the speed of the HRV. * Have a contractor balance the HRV.
Why is my Direct Air Fan air too humid?
If the air from your Direct Air Fan is too humid, here are a few things you can try: * Reduce the desired level of humidity. * Combine this step with the use of continuous exchange mode. * Wait until the outside temperature stabilizes (winter). * Heating will also improve the situation. * Store a majority of your wood outside; even dried, a cord of wood contains more than 20 gallons of water. * Arrange the outside vent for the dryer. * Open curtains or blinds; bay or bow windows may require a mechanical method. * Balance HRV. * Open the door or install a grill on the door.
How to fix condensation or ice build up in insulated duct to the outside of Direct Air PHRV 140 Fan?
Condensation or ice build-up in the insulated duct to the outside of your Direct Air Fan can occur due to an incomplete vapor barrier around the insulated duct, such as a hole or tear in the outer duct covering. To resolve this, tape and seal all joints, tape any holes or tears made in the outer duct covering, and ensure that the vapor barrier is completely sealed.
Why is my Direct Air Fan air too dry?
If the air from your Direct Air Fan is too dry, you can increase the desired level of humidity, change the ventilation mode from continuous mode to standby, and balance the HRV.
