Question submitted to Aprilaire:
The electronic water valve is that supposed to regulate the water flow or is it an on/off? It started releasing water at full rate when activated and it splashes water back on the cover and on the floor vs the drain. It's never been restricted from the saddle value and this was not touched. thanks
Aprilaires' response:

Aprilaires' response:
The solenoid valve is an on and off switch. When the valve receives 24 volts, the valve opens and the water then flows through the orifice which is the water regulator. The orifice is what controls the feed rate of the water.
Water splashing on the cover of the unit is a sign of entrainment. Entrainment is caused when the static pressure inside the duct work is too high. We would recommend having an HVAC contractor come to your home to measure the static pressure
Consumer question submitted to Aprilaire:
The water flow to my model 760 continues even when the unit stops (when the HVAC heater and fan stop). Does this mean the solenoid is faulty?
Aprilaires' response:
Thank you for contacting us with regards to your model 760 Humidifier. The water valve should close at the same time the humidifier's fan stops. They both receive their power from the same point inside. If the fan stops and the valve stays open, try unplugging the 760. If the valve continues to allow water through, the valve is stuck open. Without any source of power its internal plunger should spring closed. Please let us know if we can be of further assistance.

Consumer question submitted to Aprilaire:
I recently installed the humidifer and it worked fine for a few days. Now it is leaking water out the bottom and not through the drain hole. Could the filter be defective?
Aprilaires' response:
Thank you for contacting Aprilaire. Humidifiers can leak for several common reasons,
1) Is the unit level?
2) Inspect the feed tube for cracks.
3) Is the water panel in upside down?
4) Is the scale control insert cracked?
5) Does the drain line plugged or restricted?
6) Erosion of the water panel do to reverse osmosis (RO) or deionized (DI) water.
7) Heat registers in the house that are closed?
Closing heat registers can cause high pressure in your ducts which can blow water off of the water panel. If the static pressure in the duct is more than .4" of W.C. water will be sprayed off of the water panel.
I hope this helps. If you still can't stop the unit from leaking you will need to contact your local HVAC contractor or you can call our technical support department for more trouble shooting assistance. You can reach us at 1-800-334-6011 Monday - Friday from 7:00 AM to 5:00 PM central time.

Consumer question submitted to Aprilaire:
I have a condominium of approx. 2000 sq. ft. Is there a unit I can attach to auto water feed and which can be mounted on a wall?
What are the requirements, i.e. weight, drainage facility, etc.
Aprilaires' response:
Aprilaire offers two humidifiers (Models 350 and 360) that can run independently from any HVAC system.
These systems require a 120 VAC outlet, a drain line for the excess water and they need to be connected to the hot water line. Review the literature and installation instructions.

Consumer question submitted to Aprilaire:
Is it possible to upgrade the efficiency of the pre-filter from the current MERV-8?
Aprilaires' Response:
Thank you for contacting us with regards to our Model 1750 Dehumidifier. We do not offer a high-efficiency filter for this model other than the supplied MERV 8. However, if this unit were attached to your HVAC system and its intake positioned downstream of your HVAC filter, that could potentially have a higher efficiency than MERV 8. In that situation, the internal filter would not be needed as all air it uses would be pulled through your HVAC filter. For example, our Aprilaire whole-home air cleaners begin at MERV 10 and go higher from there. The two could work together to give the 1750 cleaner air than the dehumidifier could create on its own.
We appreciate the opportunity to be of assistance.

Do you remember last spring when all the snow was finally melted and it got warm enough
outside to go without a jacket? Do you also remember that it wasn't warm enough to turn on the air conditioning, but you still felt uncomfortable? This happens every spring due to the high levels of relative humidity (RH). The phrase "it's not the heat, it's the humidity" is all too true. High RH levels can make it feel like it's 5 to 10 degrees warmer than it actually is. One way to combat this is to turn on your air conditioner, as moisture removal is a natural byproduct of air conditioning. But in order to remove the excess moisture, you need to cool the air to a level that makes you too cold. 
Aprilaire to the rescue
A whole-house dehumidifier from Aprilaire works in conjunction with your home’s HVAC system to remove excess moisture from every room of your home. Unlike air conditioning that is designed primarily to cool your home, Aprilaire removes moisture when AC is not required, efficiently removing moisture and providing the comfort you deserve. Maintenance is a breeze with Aprilaire as well. Unlike portable dehumidifiers that require you to empty and clean a tank on a daily basis, Aprilaire dehumidifiers only require an annual filter cleaning. Hassle free convenience and comfort; that's what Aprilaire is all about.
Contact your Aprilaire dealer and schedule the installation of your whole-house dehumidifier today and avoid all the discomforts you felt last year. Your family will thank you for it.

Question submitted to Aprilaire:
Do these units work independently from your current heating system.
I have a forced air unit located in a closet accessed from the outside.
This is in the mountains of Colorado where freezing is a problem. Cannot
connect humidification systems directly to the furnace for that reason.
Would this unit be hooked up to a water supply so it would work all the time or
does one need to add water when it is needed
Aprilaires' response:
Our models 350 and 360 are independent units. They do not connect to the HVAC System at all.
They do connect with a hot water line. Simply tap into a hot water line from your house so that they can get water as needed. They also need a drain line connected to them and an outlet for power.
They come with a manual control humidistat that gets mounted on a wall in your living space.

Question submitted to Aprilaire:
This humidifier is noiser than my furnace. My father and I both had these installed on our new furnaces by the same installer. His motor/fan noise is non existent and mine is louder than a bathroom fan at 3-4 sones. They both seam to be working and pumping water, but which one is running improperly? What can I do about the noise? Do I have to go with a by-pass??
Aprilaires' response:
The fan noise from the Model 700 is typically not as loud as the fan in the HVAC system, but it is a fan and fans make noise. If you can't live with the noise a bypass humidifier would be an option.
As a test you could switch the head of your humidifier with your father's humidifier to see his is really quieter. If you find that yours is noticeably louder you could have the contractor who installed the humidifiers replace the motor.

Question submitted to Aprilaire:
I am interested in installing a whole house humidifier. Primary reason is to reduce crackin
Our house is 18 months old and has a conventional A/C system with ceiling mounted air vents. At the moment they are closed and covered with magnetic vent covers for the winter.
For heat we have a gas fired boiler providing hot water for an in floor radiant heat system "warm board".
Question: Would an Aprilaire system work in conjunction with this type of heat? I assume system would relay on using A/C ducts with a continuous air flow/fan to distribute moist air.
Aprilaires' response:
Thank you for contacting us regarding your interest in the Aprilaire humidifier product line. We are happy to assist you with questions relating to a humidifier recommendation for your application. Based upon the information provided it appears that your heating application consists of hot water radiant floor heat with no duct work required for that system. This type of heating application would typically require the use of one of our self contained humidifiers such as the 350 and 360 models. However, in your application it appears that you do have an air conditioning application that is currently utilizing duct work. Since you do have an air conditioning application in the home the air handler and duct work from this application could be utilized for the use of an Aprilaire whole home humidifier. When utilizing one of our duct mounted humidifiers on an air handler of an air conditioning application, it would require that the humidifier be utilized with hot water at all times and to work in conjunction with the fan operation of the air handler. This type of installation of the application will still allow the humidifier to provide optimum levels of humidification into the home during the driest time of the year. We have listed several questions below that will assist us in identifying the best humidifier for your application at this time.
1.The square footage of the home?
2.The ceiling height within the home?
3.The age of the home?
4.Any new renovations to the home such as windows, siding, and/or insulation?
5.The number of heating systems?
6.The type of heat?
7.Is there access to a drain?
We would be glad to further assist you regarding a recommendation for your application. Upon receiving further information regarding your application, we can determine which product would be best for your application. However, the best individual to make the final decision on a product for your application is a Licensed HVAC contractor. If you could please reply to this email at your earliest convenience, we would be delighted to assist you further.

Aprilaire - fresh ideas for indoor air.
No two ways about it, cigarette smokeis hard to avoid. Even with the best air cleaner on market. Alot of scammy makers of air purifiers will have you thinking you'll never smell or be harmed by 2nd hand smoke if you use their product.
I won't do that. Even our Model 5000, the best whole house particulate removal product, will not deter the harmful affects of 2nd hand smoke. It WILL help clean your air of all kinds of nasty stuff; virus-sized particles, allergens and other contaminants.
It's best just to properly ventilate, or maybe just don't smoke in the house. Go outside with the other 2nd class citizens!

Question submitted to Aprilaire:
I have what I was told is an April Air (looks like the 700) that came as part of my high end Carrier central AC/heating system a few years ago. We had an Aprilair before and like this one, but, it's humidity is tied to the heating /AC and the wood in the house (and one guitar) are suffering from it being too dry in here. Everything is set right (humidity maxed out on the thermostat), I hear it go on all the time, and it works right, but we don't have your digital controls to get it up to about 50%. How can I upgrade your system to get more humid air? Luckily Fender fixed my guitar but I was told dry air caused the damage and it has never left this house and a new hygrometer puts the humidity at less then 40%. If I need a new and better AprilAir fine. If this one can be upgraded, that is even better.
Thank you
Aprilaires' response:
Thank you for contacting us regarding the Aprilaire product line. We are happy to assist you with questions relating to the operation and performance of your humidifier. Our humidifiers are designed to provide and control up to 45% relative humidity. Our humidistat controls will only allow the humidifier to provide 45% humidity into the home before it will no longer initiate a call for humidity. If you are trying to maintain more than 45% humidity in the home, we would recommend working through your heating and cooling contractor for a 3rd party control that has a higher limit in regards to humidity control.
In order to get optimum levels of humidification within the home, we would recommend utilizing the humidifier with hot water as the water source, and also to allow the humidifier to operate with the fan operation of the heating system. By utilizing the humidifier with hot water as the water source this will help increase the evaporative capacity for the model 700. You will also get optimum use of the model 700 by wiring this unit to operate in conjunction with the fan for the heating application. What this allows you to do is to humidify the home essentially 24 hours a day. Basically, when putting the fan to the on mode you will be able to provide humidity into the home even though the actual heating system is not actually producing heat at the time. The heat from the water will provide the heat that is needed in the evaporation process. By utilizing the application with hot water and fan operation you will be optimizing the performance of our product and be providing a higher level of comfort within the home.

Question submitted to Aprilaire:
I have the Aprilaire 700 model (several years now) & we noticed our RH was very low. While the solenoid activates & water is running, I found the fan never activates now. I even tried the "test" mode & it would activate. I am thinking since the water solenoid is working the control panel should be OK and I have a fan failure. Is there some way I can verify this. And I didn't notice replacement fans here on your site. Please confirm for me.
Aprilaires' Response:
By what you are stating, when you put the controller into test mode, the fan will come on with the water flow. But, for normal operation only the water flows?
Since the fan does come on in test mode, but the level of RH is low in your home, anyone would question the fan at this point. Why wouldn't it come on for normal operation. Or, is the fan ok, and the solenoid is open too much?
As you are aware, proper operation calls for both to be working at the same time. The fan running when the solenoid is open.
We do not sell these type of parts online. You would need to get these from an HVAC technician. Also, they would best be able to determine which is the problem and would need to be replaced.

Question submitted to Aprilaire:
I have a two story house with a model 500 on the second floor and one also on the first floor. second floor is 2,000 feet and first is 3,000 feet. My humidity level on the first floor is 31%...what is wrong...I have it set at 45%.
Aprilaires' response:
Your Aprilaire Model 500 humidifier is designed to operate any time your HVAC furnace is operating. If your furnace is not operating your humidifier can not operate. As a result even though you have your control set to 45% the humidifier can not run unless the furnace is producing heat. We also design all our humidifiers to maintain an indoor relative humidity of 35% whenever the outdoor temperature is 20F or above. Some homes may be able to maintain more than 35% but not every home will be able to.
In addition if you did not have a humidifier prior to January 2010, it will take some time for the humidity level to increase in your home. Prior to the humidity staying in the air, all the wood and furnishings will soak up the humidity.

Question submitted to Aprilaire:
Can the inlet and outlet of the 2210 be reversed? Because of the pitch
of my roof I can only install the unit in one direction.
Aprilaires' response:
The 2210 can be installed with the inlet and outlet side reversed. The important point is that the filter media needs to be installed with the airflow arrow in the proper orientation of the air flow of your HVAC system.

Question submitted to Aprilaire:
Last season, the humidifier worked great, no problems. This season, the water just runs through the water panel without distributing out and wicking throughout the whole panel. I've replaced the panel, replaced the distribution tray and still the same thing. Is there something else that can be done? Please advise.
Aprilaires' Response:
The way the humidifier works is; when the furnace comes on, the humidistat calls for humidity and the humidifier turns on. The water solenoid valve opens, water comes up the plastic feed tube and falls into the water distribution tray. Then if the humidifier is level the water will fill up in the distribution tray and will go down the six holes in the tray equally. Then water goes down through the center of the water panel and any water that wasn't evaporated goes down the drain.
The water panels are made out of multiple sheets of slit and expand aluminum. The slits in the aluminum are angled to funnel the water to the center of the water panel. So the water panel should be wet in the center and almost dry on the outside layers.
If you have lack of humidity you may need to increase the humidifiers runtime. The most common reason for lack of humidity is lack of run time. If the humidifier runs every time the furnace comes on, runs whole time the furnace is on, and gets forced to turn off when the furnace goes off, it is added as much humidity as the furnace is allowing it to. If the humidifier could run longer it would. So if the humidifier is wired to run with the furnace fan, and if the humidifier is connected to hot water (140 Max) it can add up to 18 gallons of water to the air per day. You can turn your furnace fan on at the thermostat, let run your furnace fan continually and let the humidifier run as many hours a day as it needs to.

Last season, the humidifier worked great, no problems. This season, the water just runs through the water panel without distributing out and wicking throughout the whole panel. I've replaced the panel, replaced the distribution tray and still the same thing. Is there something else that can be done? Please advise.

The way the humidifier works is; when the furnace comes on, the humidistat calls for humidity and the humidifier turns on. The water solenoid valve opens, water comes up the plastic feed tube and falls into the water distribution tray. Then if the humidifier is level the water will fill up in the distribution tray and will go down the six holes in the tray equally. Then water goes down through the center of the water panel and any water that wasn't evaporated goes down the drain.
