Aprilair 700m Install with Ecobee Thermostat. I installed with three parts, the humidifier, the included 24v transformer, and the thermostat. Run them in a series using both the ACC+ and the ACC-, this allows the Ecobee to act as a switch and a digital Humidistat. 1 wire from transformer to Humidifier, 1 wire from transformer to the thermostat (doesn't matter which one), then the other wire from the Ecobee to the Humidifier. Works great and nobody has documented this. You're welcome Ecobee.
Was wondering if the Aprilair 700 can be installed on central air conditioning ductwork if hot water supply is available. I have baseboard heat and would rather not install something in the walls like the Aprilair 350/360.
Thank you for contacting Aprilaire! The Model 700 can be installed on either the supply plenum or cold air return of a forced air handling system. Hot water is recommended (140°F max) to provide maximum evaporative capacity. The humidifier functions with cold, hot, softened, or unsoftened water. Please note that installation by an HVAC Professional is always recommended. If you have any additional questions, we'd be happy to help.
I have the model 700 installed on the supply side plenum of the furnace in the basement. I have all my house ductwork are sealed tight, and I did caulk where the humidifier frame is attached to the plenum, but there is noticeable air leakage out of the humidifier through the vent slits and where the cover meets the frame, especially during the A/C season. Any suggestions for sealing this?
Thank you for contacting AprilAire! Would you mind giving us a call? We're hoping to talk through this further. We'd be happy to assist you. Our team is available at 800.334.6011 Monday through Friday, 7:00 a.m. to 5:00 p.m. CT.
Houses in San Antonio are equipped with fiberboard plenums rather than sheet metal. Can/should this be mounted on a fiberboard plenum? All the videos I see show the quarter-turn devices that lock it in place used on sheet metal. They would not work on fiberboard.
Thank you for contacting AprilAire! We recommend making a cutout in a section of the fiberboard and mounting a piece of sheet metal in its place. You can then mount the humidifier to that piece of sheet metal. If you have any additional questions, we would be happy to assist you.
In my situation I have to install the Humidifier unit about 30 inches above the coils. (Electric forced air furnace) For some reason just above the coils there is only half the plenum size of a regular run and its on a 45 degree angle. My problem is the instructions say to mount the humidistat ABOVE the humidifier unit on the return plenum. I can't do that or I could never reach the humidistat. Does mounting it below the humidifier on the return plenum cause a problem?
Thank you for contacting AprilAire! We recommend against that because the sensor is on the back of the controller, so if we do that then the sensor would be below where the humidifier itself is. The reason the controller has to be above the humidifier is so it senses the humidity before it reaches the unit itself. If you have any further questions, we can be reached via email at support@aprilaire.com or by calling 800.334.6011. A team member is available to assist Monday through Friday, 7:00 a.m. to 5:00 p.m. CT.
Help! I have a downflow gas furnace. Coil is sitting on floor(no room on supply). Can I install this on the return? (Top of furnace as its a downflow). Looked up online but some are saying i will need a bypass one, but i don’t have room as coil sits on the floor. Thanks guys
Thank you for contacting AprilAire! We would not recommend installing a Model 700 on the return side as it would never get heat from the furnace which would reduce its humidification capacity. We would likely recommend a Model 600 instead for this scenario. As a next step, we recommend discussing options with your local contractor before choosing a unit. If you have any additional questions, please feel free to contact us at 800.334.6011 or via email at support@aprilaire.com.
With the fan does it pull air from the the outside of the system to push into the duct work? my unit is installed in my crawl space and i wouldn't want that air pulling into my house.
Thank you for contacting AprilAire! The Model 700 fan pulls air out of the ductwork and across the water panel to get humidity, then pushes that air back into the ductwork through the vertical openings on either side of the base. Some air will escape out of the vent slits on the cover to cool the motor, but it will not pull any air from the surrounding area. If you have any additional questions, we'd be happy to assist.
Hi Scott - Thank you for contacting AprilAire! We appreciate you bringing this to our attention. The notch should be facing toward the ductwork. If you have any additional questions, we would be happy to assist.
would this work not installed into ducting? i'm trying to add humidity to a warehouse that doesnt have ducting. if this was installed open to the air would it work? thanks
Thank you for contacting AprilAire! AprilAire evaporative humidifier models 400, 500, 600, and 700 need to be mounted on the ducts for installation. Our Model 300 operates completely separate from the HVAC system and does not require ductwork, however, it is mostly meant for residential applications. It can be used in some commercial applications if the space is small enough. It also depends what humidity levels you require as well. That being said, if your space is larger than 1,000 square feet, the Model 865 (one of our steam humidifiers) will be your best option. You can find more information on this product at www.aprilaire.com/whole-house-products/humidifier/model-865. We would be happy to discuss your application in more detail and can be reached at 1-800-334-6011 Monday through Friday, 7:00 a.m. to 5:00 p.m. CT. Thanks again for contacting AprilAire!
Is there a way to test the Aprilaire? Mine was installed and I had been told all is well. However, I have 72% humidity in my house even though it’s set on 45% via the thermostat.
Hi Kelli - Thank you for contacting AprilAire! Would you mind giving us a call at 1-800-334-6011? We would be happy to assist you. A team member is available Monday through Friday, 7:00 a.m. to 5:00 p.m. CT.
Thank you for contacting AprilAire! This depends on which evaporative unit you're looking at. If it’s the Model 300, then yes, it would be pulling air from the basement if that’s where it is installed. For our other evaporative units (Models 400, 500, 600, and 700), since they will be mounted on the ducts, they will be using the air from the living space to humidify. If you have any additional questions, we would be happy to assist. Thanks again for contacting AprilAire.
So does this thing work whether the central air is running or not? Due to our temperature settings, sometimes the central air does not run for days both summer and winter time in Vegas. Would that be a problem?
Thank you for contacting AprilAire. The Model 700 with automatic control (Model 60) can activate the furnace blower when humidity is needed and the furnace isn’t already running. If you have any additional questions, we would be happy to assist.
Thank you for contacting Aprilaire! We are assuming you're referring to the humidifier being on the return side so it blows through the air cleaner and into the furnace. The short answer is no, it will not affect your filter. The humidifier, air cleaner, dehumidifier, and other items are all designed to work together as a system to provide your home with the healthiest air. Your humidifier is designed to work on either side of the furnace, taking into consideration that the system will have an air cleaner in the return duct. Our humidifiers evaporate the water into the air as a vapor. The water will turn into a vapor like drying your clothes on the clothesline using the sun and wind to make that happen. If you have any further questions, we'd be happy to assist!
@@aprilaireco Is there any issue getting water vapor through a 4 inch filter. It seems like some will come through but not a lot. Frustrated mine is on return but supply has no space. Thinking of getting a non fan operated humidifier.
@@tuanische Thank you for contacting AprilAire! Water vapor has no issue passing through a furnace filter. The water evaporates off of the water panel and stays as a vapor after that. The heat to evaporate comes from the hot water and/or hot air from the furnace. If you have any additional questions, we would be happy to assist.
Thank you for contacting Aprilaire! Yes, you can connect the model 700 to the 8910W thermostat. We recommend calling your HVAC contractor as this would involving wiring from the humidifier to the EMS board. If you have any questions, please give us a call at 1-800-334-6011.
Thank you for contacting AprilAire. We apologize for not getting back to you previously. We recommend connecting with your local HVAC professional to assist with your humidifier if you haven't already. If you have any questions, we can be reached at 1-800-334-6011.
I have my air conditioning coil above the heat exchanger, can the apilair 700M be installed in same spot as the AC coil. unfortunatly there is no other space on supply that is vertical before it hits the basement rafters
Thank you for contacting Aprilaire! We do not advise installing the Model 700M Humidifier in front of the air conditioner coils. If you do not have available space on the ductwork, it may be best to look into a humidifier that does not require as much space, such as the Model 800 Steam Humidifier. If you have any further questions, we would be happy to assist.
Question. I have mine installed on the supply side, and when the humidifier fan is running and my furnace is running I can feel air being blown back out of the vents of the humidifier. Is this normal? Doesn’t that mean the humidifier isn’t pushing humid air through the house since it’s getting blown back out of the grille of the humidifier?
Thank you for contacting AprilAire! The air that is being blown out of the vents is air that is being utilized to cool the fan motor. This is normal and is not going to affect the humidification output of the unit. If you have any additional questions, we can be reached at support@aprilaire.com or by calling 1-800-334-6011.
AprileAire's response is nonsense. The fan blowing your humidifier air does not need air to cool it. Good Lord, what a bunch of garbage. That fan isn't generating any heat. You really should seal it up or move it to your return air side. Just out of curiosity, where exactly on your supply side do you have it installed? Above the AC coil or down by the blower motor?
@@Balticblue93 above the AC coil. Which is what the aprilaire manual specified. Not sure if that’s best or not but that’s what it said. And due to where my system is I literally couldn’t do it on the return side. It’s in a reeeaaally tight utility closet.
I’m noticing lots of water coming down the tube as if the water isn’t even being blown through the duct work.. it’s just going straight into my drain..
Thank you for contacting AprilAire. The Model 700 evaporates a portion of the water that flows through it and drains the rest. About two gallons draining per hour is normal. If you have any additional questions, we would be happy to assist.
Thank you for contacting AprilAire. For the Model 700, you will need 1/2" I.D. hose. If you have any additional questions, we would be happy to assist.
AprilAire. Why install the humidifier on the return with cold air and not on the hot air supplier duct? I assume with hotter air, passing through the humidifier would be more efficient, increasing the water evaporation and thus less water wasted into the drain. Please advise.
Thank you for contacting AprilAire. A supply side install is our recommended configuration in the installation manual, but it can be installed on either the supply plenum or cold air return. You are correct that the hot air will evaporate more water. If you have any additional questions, we would be happy to assist.
Thank you for contacting AprilAire! Hot water is recommended (140°F max) to provide maximum evaporative capacity. The humidifier functions with cold, hot, softened, or unsoftened water.

It's a probably a timed thing. The filter isn't so much a filter as it is a wick and can clog with minerals which will cause it to be ineffective. If you have good water I would think you could get away with fewer filter changes.

@@aprilaireco i figured it out!! Turns out I had the harness that holds the filter upside down when I was trying to put it back on. durp!! Maybe worth mentioning in a future video.
Hi I just had this unit installed by an hvac installer , he installed it on the return duct . Should this be installed on return duct or supply duct ? Thanks
Thank you for contacting Aprilaire! The Model 700 can be installed on either the supply plenum or cold air return of a forced air handling system. If you have any additional questions, we'd be happy to assist.
@@grgryl Thank you for contacting AprilAire! Although the humidifier can be installed on either the return or supply side, we do recommend the Model 700 be installed on the supply side for maximum effectiveness. On this side, it will get heat from the furnace when it is running which will increase evaporation. If you have any additional questions, we'd be happy to assist.
@@aprilaireco Thank you, since my ducts are under the concrete slab, the evaporator sits directly on the ground where the air is sucked into the ducts, so there is no room/duct work above ground. Would you recommend installing the 700 on the evaporator coils by cutting a hole in the cover?
@@grgryl Thank you for your question. This is something we would recommend you go back to your installing contractor for as it will directly affect your HVAC system which we cannot advise on. Thanks again for contacting AprilAire!
