I am interested in installing an Aprilaire whole house humidifier in my own house

Wednesday, March 6, 2013 by Aprilaire Team

Consumer question:

I am interested in installing an Aprilaire whole house humidifier in my own house without a contractor. I have radiant heat so the only ducting I have is for air conditioning. I was wondering if having room temperature air circulation (no air conditioning) would still be effective to evaporate enough water to generate humidity within the specs of the controller. I understand that I would have to periodically have the blower turn on in the heat season in order to simulate a furnace blower, but that is no problem. Im more concerned that because the air would be 70 degrees, that the evaporation would be so slow that the controller would be telling me to replace the filter all the time.

thank you... please give me your suggestions on your best product for this 2200sq foot area and situation.

 

Aprilaires' response:

Thank you for contacting us regarding our whole home humidifiers. You would be able to utilize a whole home humidifier on an air handler unit that is not used for heat. Simply supply the unit with hot water and you can add humidity with moving room temperature air through the water panel.

Based on the size of your home, the 600 should be sufficient. However, there are other factors that may affect the performance of the humidifier. Factors such as ceiling height, age and tightness of the home, water temperature, and desired humidity level all contribute to the humidifiers ability to reach and maintain a given humidity setpoint.

We recommend the installation be done by a licensed HVAC contractor. When installed by a licensed contractor, the units come with a 5 year warranty. If you choose not to use a licensed contractor you risk voiding the 5 year warranty. Additionally, the contractor has the ability to come to your home and evaluate your needs. This will help you make the best decision as to which humidifier will work best in your particular installation.

Just noticed that my Aprilaire Air Cleaner is installed backward, should I get it fixed?

Monday, March 4, 2013 by Aprilaire Team

Consumer question:

I just changed the filter in a Aprilaire model 2200 with one of your replacement filters.

It is obvious from the arrow on the filter basket and the fact that the black plastic combs face into the incoming air, that the unit was installed upside down.

Is this a serious matter that would make it worth having the unit professionally removed and reinstalled in the correct direction?

 

Aprilaires' response:

Thank you for contacting us regarding your model 2200 air cleaner. Air passing through the air cleaner in the wrong direction could lead to air leakage around the filter, increased air resistance, or filter collapse as the filter is structurally supported against air flow only in one direction. The efficiency of the Aprilaire air cleaner is not affected. If an older model air cleaner has been installed incorrectly, we recommend that either the original installer or another service contractor revisit the installation and reposition the cabinet so that the air flow passes through the air cleaner properly. Some sheet metal work may be required so that the return air duct can be attached to the flange on the inlet side of the outer housing when the air cleaner is turned in the proper direction. In addition, sheet metal work may also be required at the furnace so that the flat outlet side of the air cleaner can be attached to the furnace return air opening.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

Have had a Aprilaire model 560 humidifier since 1995 but looking for a new one, please help!

Wednesday, February 20, 2013 by Aprilaire Team
Consumer question:
 
Could you please find us the square footage the model 560 aprilaire humidifier unit is rated for? I'm exhausted trying to find any 560 information, we have had this one since 1995. We're considering one of your larger, more modern units. Thank you.
 
Aprilaires' response:

Dear Rich,

Thank you for your email regarding your model 560 Aprilaire humidifier. The model 560 was discontinued in 2002 and replaced by the model 600. Both models will effectively humidity a tight home up to 4000 square feet with a .50 air change rate. As homes age they can become less tight and humidity can escape. We design all our Aprilaire humidifiers to maintain an indoor humidity level of 35% at an indoor room temperature of 70F anytime the outdoor temperature is 20F or above. The operating time of the HVAC system will directly affect the operating time of your model 560.
 

 

Sand/Silt in my water, is that effecting my Aprilaire steam humidifier?

Thursday, February 14, 2013 by Aprilaire Team
Consumer question:
 
I had installed about 4-5 months ago. I get a build up a yellow/brown sand / silt in the bottom which seems to clog the drain and causes the canister to leak from the top. I live in the Denver area (Lone Tree). I saw a post on another web site with a similar issue. Do you have a recommendation to fix? Maybe a sand/silt trap/filter upline?
 
 
Aprilaires' response:
 
Thank you for contacting us with regards to your model 800 Residential Steam Humidifier. What you're finding is the sediments in the water that are left behind as the water boils away. The exact nature of these sediments can vary by region. We don't have any specific recommendations for filters, but if you do choose to have on installed, do not use one that de-ionizes or de-mineralizes the water, such as Reverse Osmosis. Some amount of dissolved minerals are required for our unit to produce steam. The 800 uses the minerals in the water to pass current between two electrodes, and the fewer minerals in the water, the longer it will take to reach boiling. We would recommend that you consult your installer for recommendations on filters for sand, though.

Replacing an existing Aprilaire model 760 humidifier, couple of questions...

Monday, February 4, 2013 by Aprilaire Team
Consumer question:
 
I want to replace the existing 760 model, however, due to the size to the furnace, it cannot be any larger than the existing unit. The current model 700 is about 2 inches higher so I can use it. What model would you suggest I use and what if any issues will I run into.
 
 
 
Aprilaires' response:

Thank you for contacting us regarding the replacement for you model 760 humidifier. If you are unable to replace the 760 with the 700 then you could use the model 600. The 600 is a bypass humidifier which operates slightly different than the 760 or 700. Where the 760 and 700 are power humidifiers that use an internal fan to add humidity to the air in the duct work, the 600 is a by pass unit that utilizes the HVAC blower to add the humidity to the air.

The 600 has similar capacities to the 700 and can provide humidity on a tight home with 8 foot ceilings of up to 4000 square feet.

Additionally, due to the differences in the installation, as well as the wiring of the humidistat control, we recommend the installation be done by a licensed HVAC contractor. When installed by a licensed contractor, the units come with a 5 year warranty beginning on the date of installation. If you choose not to use a licensed contractor you risk voiding the 5 year warranty.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

Does basement humidity have affect on my humidifiers operation?

Monday, December 31, 2012 by Aprilaire Team
Consumer question:
 
Aprilaire model 500 humidifier installed on 2-stage 95% furnace. Sensor is located inside cold air return from house. Cold water to humidifier. Does basement humidity have affect on humidifier operation ie. humuduty levels in residence. Have dehumidifier in basement set at 40%. On setting five humidity in residence is 32-35% Setting 6 36-39% Is this normal? I think it should be higher. Humidifier works in test mode. Insight?
 
Aprilaires' response:

Thank you for your email regarding your model 500 Aprilaire humidifier. Your Aprilaire humidifier control measures the humidity in the cold air return which is the air coming back to your HVAC system from your entire home. A dial setting of 5 would be equivalent to an indoor relative humidity of 35% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. A dial setting of 6 would be equivalent to an indoor relative humidity of 40% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. We design our humidifiers to maintain 35% anytime the outdoor temperature is 20F or above and the indoor temperature is 70F. The actually humidity a specific home will vary due to the tightness and cubic footage of the home as well as the runtime of your HVAC system. In addition a humidity level higher than 35% may cause damage to home. This is because as the temperature outside drops, the air in your home may not be able to maintain a humidity level above or even equal to 35%. If the humidity level is too high for the current outdoor conditions, the result is condensation on your windows. This is described in the attached owners manual. Based on the information you provided it appears your mode 500 is performing properly.

 

New model 400, installed 8 days ago...but I'm still a little dry?

Monday, December 3, 2012 by Aprilaire Team
Consumer question:
 
I had an Aprilaire 400a humidifier installed on my 3 story town home (1 1/2 years old) about 8 days ago. After adjusting settings on the unit, the humidity in my home peaks at approximately 27% at maximum settings and with the blower on.

This morning was the highest that the unit registered and that was 37% internal humidity, but it rained all night and the humidity outdoors was above 50%.

I have contacted the dealer/installer and they assured me that they're going to talk to their management to see if there's an issue, however I am told that it may just be because of my home.

I'm not sure if that's accurate, as my home is less than 2 years old and is tightly constructed. I went with the larger humidifier that they offered, however i'm concerned that reaching 27% humidity on max settings when it is 25-35 degrees outside is going to be an issue.

Any feedback you can provide would be greatly appreciated.
 
 
Aprilaire's response:

Thank you for your email regarding your model 400 Aprilaire humidifier. Any Aprilaire humidifier is reliant on the HVAC system to be operating in order to add humidity to your home. While your model 400 will add some humidity during a blower only call, it primarily is adding humidity during a heat call. If your heat call is short, then the humidifier will have a short operating time as well. Homes also will require time to build up the humidity level when a humidifier is first installed. Since your model 400 was only installed 8 days ago it may just take more time to raise the humidity level. At this point we would ask you to give it another week or two. Your home has had all winter to lose moisture and it will take time for the home to soak up moisture created by the humidifier.

 
 

 

Our Aprilaire 760 humidifier has been installed for 14 years. But I have a question.

Thursday, July 5, 2012 by Aprilaire Team
Consumer question:
 
Our 760 has been installed for 14 years. The insulation material on either side of the fan had to be removed. Should I replace it with new pink fiberglass insulation? It appears that is where the unit pulls in air.
 
 
Aprilaire's response:

Thank you for you using Aprilaire in your home comfort system.

I am somewhat perplexed that your system had been operating for 14 years with insulation restricting the air flow. Normal installation does not necessitate the blockage of air into the humidifier. This may have been done to prevent water leaking from the humidifier in high static pressure within the duct system. I would recommend having an HVAC contractor look at the system to determine the reason for the use of insulation; it was not for filtering the air.

If you have additional questions, please contact us.

Can a UV light be installed by my Aprilaire Humidifier?

Friday, May 25, 2012 by Aprilaire Team

Consumer question:

I plan to install the UV-C light in the supply air plennum above the AC evaporator coil. How far away from the humidifier should the light be? I understand the UV light may damage plastic parts? or is there no problem?

Aprilaires' response:

Thank you for your email regarding your Aprilaire UV-C Light. You are correct, the light will damage the plastic parts on your model 700. Mounting your UV light at least 8 inches above the AC coil the model 700 cannot have any direct light. Therefore you can shield the light from the model 700, or a better alternative would be to move the model 700 to the return side of your HVAC system and supply it with hot water.

 

What humidifier is right for my 1500 sq ft house in Alaska?

Tuesday, March 13, 2012 by Aprilaire Team
Consumer questioni:
 
I have a 1500 sq. ft. house in Alaska. Very dry in the winter. We have a forced air furnace and a HRV system. Also have hard wood floors that currently are shrinking due to RH in the home of 32%. What humidifier do you recommend to meet our needs?
 
Aprilaires' response:
 
Thank you for contacting us with regards to our Aprilaire Humidifiers. Based on the information provided, we could recommend any of our units. Other factors to consider are the age of the home and its relative tightness. The presence of an HRV system must also be taken into consideration. These systems typically provide a constant stream of fresh (and dry) air to your home. HRVs can actually work against your humidification needs by removing humidity already inside the home. You may want to weigh the benefits of the HRV operating during your humidifying season versus meeting your humidifying needs. We would recommend that you contact your local HVAC installer to have them visit your site and provide you with an assessment of your humidity needs and what Aprilaire humidifier would best meet them.

 

What Aprilaire unit should I use to replace my old 110 humidiifer?

Thursday, March 8, 2012 by Aprilaire Team
Consumer question:
 
The 110 does not seem to perform as it should any longer and may need to replace it. What is a replacement that will fit the 110 opening on the furnace
 
Aprilaires' response:

Thank you for contacting us regarding the replacement for your model 110. From an operational standpoint the model 700 would be the replacement for your 110. However, due to size differences there would be some resizing of the opening on your duct work.

Additionally, we recommend the installation be done by a licensed HVAC contractor. When installed by a licensed contractor, the units come with a 5 year warranty beginning on the date of installation. If you choose not to use a licensed contractor you risk voiding the 5 year warranty.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

 

UV lights? Okay with my Aprilaire?

Friday, March 2, 2012 by Aprilaire Team
Consumer question:
 
Will the aprilaire media's standup to UV lights? I know the honeywell's at one time would get holes in them within a few months. And if the aprilaire's are compatable how far away does the light need to be?

Aprilaires' response:

Thank you for contacting us regarding our Aprilaire air cleaner filters. We do not recommend any exposure from UV light onto our filter media. Our filters are made of acrylic and polypropylene fibers that break down when exposed to UV light. This break down could lead to shortened filter life and lowered efficiency.

If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.

Which side of the furnance can my humidifier be installed?

Thursday, March 1, 2012 by Aprilaire Team
Consumer question:
 
I have not yet purchased a whole house humidifier yet. My question is what kind would you recommend in my situation. My house is on a slab and the cold air return is through the attic down into the furnace unit. I have no one of attaching a bypass pipe to the supply ducts since it is underground. Is there a unit that I can install solely on the return side of the furnace?

Aprilaires' response:

Thank you for contacting Aprilaire.

Yes, you could install the 700 on either side of the furnace, and it does not have a bypass to go to the other side. You will need to run hot water to this humidifier.

We do not recommend installing any humidifier in an attic where conditions may freeze.

Other wise you could go with a stand alone unit, the 360. That goes through a wall. It does not connect to the HVAC system at all.

 

Could my solenoid value be bad?

Monday, February 13, 2012 by Aprilaire Team
Consumer question:

I just installed this unit and realized there is no water flowing to the filter. The valve has power on both wires (24VAC using the step down unit provided). The water has also been checked and is going into the valve however, not coming out. Do you have a suggestion of what the issue could be or is it most likely a faulty valve?

Aprilaires' response:

Thank you for contacting us with regards to your model 600A Humidifier. When power is applied to the solenoid valve, there should be an audible "click." If your valve does not click, verify the voltage supplied to it by measuring between the two yellow wires at the valve for A/C power. It should be around 24v, +/- 4v. Additionally, the amps available are also important. This valve needs .4 amps to open. If the amperage available is less than .1, it may not click at all. Between 1. and .3 it may just make a humming noise. If you verify all power is good and it still doesn't open, the diagnosis would be a bad valve. We would recommend that you contact your supplier for any replacement needed.

I have a question about the Aprilaire humidifier I want to purchase.

Monday, February 13, 2012 by Aprilaire Team
Consumer question:

Hi, I have a question about the Aprilaire humidifier I want to purchase . Will it work just as well if it is installed on the return ducts , because on my system I don't think you can install it on the forced air side it get all rooms in the house . I see it has it's own fan , is it really strong enough to blow the mist to the rooms on the upper floors also this fan works seperate from the furnace fan ?

Aprilaires' response:

Thank yo for your email regarding your interest in our Aprilaire humidifiers. The model 400A is a drain less bypass humidifier which can be installed on the supply or return duct. It utilizes the fan of the HVAC system to force the air through the humidifier as well as to distribute the humidified air through your home. The 400A has no internal fan.

I love our Model 350, but it's vented into the main part of the house and it's very noisy.

Sunday, February 12, 2012 by Aprilaire Team
Consumer question:

I love our Model 350, but it's vented into the main part of the house and it's very noisy. Do you have a similar model that's quieter? Or can we replace the fan with one that's not so loud?

Aprilaires' response:

Thank you for contacting us with regards to your model 350 Humidifier. The replacement parts for this unit would be the same ones that originally came with your unit. We don't offer alternate motors and fan blades. If you feel that your unit is operating at a higher noise level than when it was originally installed, you might look into replacing the motor. Fan blades don't typically wear out. Also, this model can be ducted in applications where the unit isn't in the space that it's humidifying. Flexible duct will offer more sound dampening properties than rigid duct, and more distance between the humidifier and its discharge vent will also help. We would recommend that you contact either your installer or current HVAC service technician to discuss each option.

Please let us know if we can be of further assistance.

Model 800 has 3 sets of capacity, which one is right for me?

Saturday, February 11, 2012 by Aprilaire Team
Consumer question:

My house is 6000sq ft. What capacity should my Aprilaire model 800 humidifier unit be set to, 11.5,20.5,or 23.3 gallons per day? Also how do I know what its set at now? I cant seem to get it about 37% humidity. I have a digital new thermostat.

Aprilaires' response:

Thank you for your email regarding your model 800 Aprilaire steam humidifier. Your model 800 can work with a 110, 208 or 240 volt power supply. The higher the voltage, the higher the gallons per day output. A power supply of 240 will produce 23.3 gallons per day. A home of 6000 sq. ft with 8" ceilings would typical need 23- 25 gallons per day. Your HVAC installer would know how they sized your home for humidification and what power supply they used. As long as your thermostat has dry contacts, it may be used to control humidification from your model 800. We ask for you to please contact them to discuss how they have wired your system.


My solenoid is open with no voltage, what's up with that?

Tuesday, January 24, 2012 by Aprilaire Team

Consumer question:

I have a 560 humidifier with a model 883321B controller. The past 6 years we owned the house we never used the humidifier but now we are trying to use it. We recently had a evaporator coil and new thermostat installed and the installer ran new wiring for it. When I tried to run the humidifier, water continually runs weather the furnace is on or off and no matter what the humidistat is set to. There was no voltage at the solenoid valve when I checked.

Aprilaires' response:

Thank you for contacting us regarding your model 560 humidifier. When the unit is wired properly, the solenoid valve should only open when the furnace and HVAC blower is running. If there is no voltage at the solenoid and it is open, then the valve may be stuck open due to a build up of particles or sediment.

In order to send you to correct wiring diagram, we would need to know if you have a manual or automatic humidistat. Additionally, to better understand why your unit is not operating properly, you have the option to call our technical support department at 1-800-334-6011 to troubleshoot the unit with one of our technicians over the phone. The technician may be able to diagnose what the problem is and point you in the right direction regarding service or installation manuals.

Our tech support department is available Monday through Friday, 7 am to 5 pm CST.

My Aprilaire humidifier is leaking, please help!

Thursday, January 19, 2012 by Aprilaire Team
Consumer question:

We have an Aprilaire 760 humidifier installed on the return side of our furnace, connected to the cold water line, and the units leak water from the front edge of the unit. The HVAC tech says it is condensation build up on the water panel dripping down. Thoughts?


Aprilaires' response:

Thank you for contacting Aprilaire.

This does not sound like condensation. Actually, you should not have condensation in your humidifier.

Leaking is caused by a few different things... You will want to make sure that the water panel is not leaning forward, back, left or right. Also, make sure that the distribution tray at the top, (where the water is dropped into) make sure that there still is a gritty/sandy coating in there. If the tray is smooth where the water builds up before going into the 'collar' type holes, all the water will go into the first hole or two it comes to and will not be evenly distributed. When this happens, the water panel is not able to handle that amount of water and will go over the sides of the scale control insert and leak.

The last thing to check is if there is an orifice correctly in place. Then check to make sure that it has not been stretched out.

To check proper water flow through orifice, you would pull out the water feed tube, and have the water go into a 32 oz jar. That jar should fill in two and half minutes. If it fills way faster than that, you have too much water going in that it can not handle, and will leak out. The fix for that would be a new orifice.

You may check these things or give us a call Monday thru Friday from 7:00 am to 5:00 pm central time.
