To address condensation or ice build-up in the insulated duct of your Lifebreath Fan to the outside, consider the following: * Ensure a complete vapor barrier around the insulated duct by taping and sealing all joints. * If there is a hole or tear in the outer duct covering, tape any holes or tears made in the outer duct covering.
Why is my Lifebreath Fan frosting up?
If your HRV/ERV units and/or ducts are frosting up, it could be due to: * HRV/ERV air flows being improperly balanced; in this case, have an HVAC contractor balance the HRV/ERV airflows. * A malfunction of the HRV/ERV defrost system; ensure damper defrost is operating during self-test.
Why does my Lifebreath METRO 120ERV have poor airflow?
Poor airflow in your Lifebreath Fan can stem from several causes: * The mesh on outside hoods may be plugged, requiring you to clean the exterior hoods or vents. * Filters might be plugged, so you should remove and clean both the filter and core. * House grilles could be closed or blocked; check and open them. * Dampers, if installed, might be closed; open and adjust them. * The power supply at the site could be poor; have an electrician check the supply voltage at the house. * Ductwork might be restricting the HRV/ERV; check the duct installation. * The speed control setting may be improper; increase the speed of the HRV/ERV. * The HRV/ERV airflow might be improperly balanced; have a contractor balance it.
What to do if humidity levels are too high with my Lifebreath Fan?
If humidity levels are too high and condensation appears on windows when using your Lifebreath Fan, consider these factors: * The dehumidistat may be set too high; try setting it at a lower level. * The HRV/ERV unit might be undersized for a hot tub or indoor pool; cover the pool or hot tub when not in use. * Moisture could be entering from a non-vented or non-heated crawl space; vent the crawl space and place a vapor barrier on the floor. * Moisture might be remaining in washroom and/or kitchen areas; ensure ducts from the washroom are sized to remove moist air effectively and use a bathroom fan for short periods to remove additional moisture. * The HRV/ERV might be set at too low a speed; increase the speed.
What to do if my Lifebreath METRO 120ERV Fan supply air feels cold?
If the supply air from your Lifebreath Fan feels cold, it could be due to the following: * Poor location of supply grilles: Relocate the grilles high on the walls or under the baseboards. * Outdoor temperature extremely cold: A small duct heater (1kw) could be used to temper the supply air.
How to fix water in the bottom of my Lifebreath METRO 120ERV?
If you find water in the bottom of your Lifebreath Fan unit, here's what to check: * Drain pans may be plugged; look for kinks in the drain line. * The HRV/ERV drain lines might be improperly connected; check the water drain connections. * The HRV/ERV may not be level; make sure water drains properly from the pan(s).
Why is my Lifebreath METRO 120ERV dehumidistat not operating?
The dehumidistat on your Lifebreath Fan might not be operating because: * The outdoor temperature is above 59ºF (15ºC); in this case, the dehumidistat is functioning normally. * There may be an improper low-voltage connection; check that the correct terminals have been used. * External low voltage may be shorted out by a staple or nail; check external wiring for a short. * Make sure that you set the dehumidistat at the desired level.
Why are humidity levels too low with my Lifebreath METRO 120ERV?
If you're experiencing low humidity levels with your Lifebreath Fan, here are a few things to check: * The dehumidistat control may be set too low; try setting it at a higher level. * The blower speed of the HRV/ERV might be too high; decrease the HRV/ERV blower speed. * Humidity may have to be added through the use of humidifiers. * HRV/ERV airflows may be improperly balanced; have a contractor balance HRV/ERV airflows.
