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.

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.

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.

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 is putting out to much humidity, so I lowered my controller...

Friday, January 20, 2012 by Aprilaire Team
Consumer question:
My humidifier was set at 7 and put too much condensation on my windows so I turned it down to 4. The condensationis just minimal now, so that's good, but the numbers don't match. When it\'s set to 4, my readings upstairs shows 36%. I thought setting 4 was 25% to 30%. Also, ideally I would like the humidity in the 40s. Is there something wrong with the settings? Is the 700 model too large for my 1500sf townhome? Its the one my hvac guy installed with new furnace. Any help you can give is appreciated. Thank you.

Aprilaires' response:

Thank you for contacting us. The setting 4 should equate to approximately 30%. Is the control mounted on the return? If so this might explain the different readings. The 700 has a large evaporative capacity however if you install a unit with excess capacity it usually just runs less.

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.

What Aprilaire humidifiers work with horizontal heating systems?

Wednesday, January 18, 2012 by Aprilaire Team
Consumer question:

I just had to return a Model 700 because I have an attic hvac unit that is horizontal. We live in the desert in St. George, UT and have a 1,450 sf house that is 8 years old. What unit would you recommend for our horizontal attic unit?

Aprilaires' response:

Thank you for your email regarding your interest in our Aprilaire humidifiers. The only model that will not work on a horizontal heating system is the model 700. The humidity level is reduced by 50%. We wold recommend the mode 600 for your application.

Thank you for giving us the opportunity to be of service

Power, power am I getting power?

Wednesday, December 28, 2011 by Aprilaire Team
Consumer question:

We are quite happy with our unit, but we have a question. When the cover is lifted off to change the filter, the plug is disconnected so the fan, of course is not moving.
But,how can we make sure the unit is getting power? We have never seen the fan blades turn even when we plug the unit in while the cover is off. Shouldn't we be able to hear the fan turning or feel air coming out of the top of the humidifier? (It's a model 760.)

I just plugged a fan into the out-let and the fan will not run. The outlet may not be wired correctly. But, please tell us if we should be able to feel air coming out of the unit or hear the fan moter?


Aprilaires' response:


Thank you for contacting us regarding your model 760 humidifier. The model 760 has its own 24 volt transformer built into the unit therefore it has all of its own power. If you would like to see if the fan is working while the cover is on, simply touch the brown leads together while the unit is plugged into a powered outlet. This would complete the 24 volt connection to the relay, turning the fan on and opening the solenoid. This is a low voltage connection so there is no risk of injury. You can perform this test while the furnace is off, this way the sound of the furnace running will not interfere while you are listening for the fan on the 760.

If the fan and solenoid operate the unit is ok. If not, we recommend contacting your installing contractor to come to your home and troubleshoot the unit. However, you have the option to contact our tech support department at 1-800-334-6011 and troubleshoot with one of our technicians. Our tech support department is open Monday through Friday, 7 am to 5 pm CST.

I need to replace my Aprilaire 760, but with what?

Consumer question:

I have a 760 that needs to be replaced (for some reason).


Aprilaires' response:

Thank you for contacting us regarding the replacement for your model 760 humidifier. The replacement for the 760 is the model 700. We recommend having this replacement done by a licensed HVAC contractor. When the units are installed by a licensed contractor it comes with a 5 year warranty on all the parts. If you choose not to use a licensed contractor, you risk voiding our warranty.

Water Runs continuously on my model 560 Aprilaire Humidifier, what do i need to do to stop it.

Saturday, December 10, 2011 by Aprilaire Team
Consumer question:

Water Runs continuously on my model 560 Aprilaire Humidifier, what do i need to do to stop it.


Aprilaires' response:

Thank you for contacting Aprilaire.

If the water is coming through the humidifier non- stop, you may want to shut the water valve till things can be checked.

Having water come through the humidifier when the furnace is not on might mean that there is direct and constant power going to the solenoid. The solenoid should only be activated when the furnace is on and there is a call for heat.

When the water is running, try turning down the humidistat... does the water stop? If so, then the problem is a lack of communication with the furnace. You may want to have an HVAC technician come out to check that for you.

Please let us know if you have any further questions.

I would like to get an Aprilaire 1750A and run it separately from HVAC.

Friday, December 9, 2011 by Aprilaire Team
Consumer question:

I would like to get an Aprilaire 1750A and run it separately from HVAC. I want the dehumidistat to have a digital readout with the usual on/off and push button up/down of humidity setting. Which dehumidistat? Model #70? Model #75? What's the difference? Another model?

Aprilaires' response:

Thank you for contacting us with regards to our model 1750A Dehumidifier. Models 70 and 75 will each work with this model. The difference lies in how the controls sense humidity and how they use that information to create a set point. The model 70 sends humidity, temperature and set point values to the dehumidifier for it to use in determining if humidity is too high. The 75 works with a simple 2-wire signal to turn the dehumidifier on and off. This is a simpler control and works the way most other manufacturers' de-humidistats will work.

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

My Aprilaire Humidifier fails to feed water when the furnace is running..

Friday, December 9, 2011 by Aprilaire Team
Consumer question:

Unit was installed in February 2011. fails to feed water when the furnace is running.....even on the highest #7 setting. Worked fine last heating season

When the dial is moved to the "Test" setting, the water will flow and the 'reset light' will blink like it's supposed to....but when moved back regular run mode - even on # 5, #6 or #7 - it will not put water into the filter pan.


Aprilaires' response:

Thank you for contacting us regarding your 600A humidifier. Our controls have a built in design condition that allows the control to make a maximum of 45% relative humidity. If the digital screen has a value of 45% or above, the control will not turn on the humidifier outside of test. Also, the control has a accuracy differential of +/- 5%. So even if the screen reads 40%, due to this differential it may not turn the humidifier on.

Once the air in your home drops below 40-45% relative humidity your humidifier will turn on to add moisture to the air.

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.

Light a blinking, what does it mean?

Friday, December 9, 2011 by Aprilaire Team
Consumer question:

Just installed a 5000. When thermostat is in the off position and I set unit to run 30 min/hr., the blue lights on the cleaner flash and the filter indicator bars are animated on the LED control panel.

When on I place the thermostat on heat, and the heat kicks in, the blue lights on the cleaner unit do not flash but the filter indicator on display/control module is animated. Should the blue lights on the filter be flashing?


Aprilaires' response:

Thank you for contacting us. The unit is going to light up when it send a signal to the furnace fan to kick on. The 30 min/hour button will give you 30 minutes run time for the based on the total amount of run time in that hour. The run time of the heat call does count toward that 30 minutes and if toward the end of that hour the control has not reached 30 minutes it will kick on the fan to get the remaining minutes. The blue light should flash when ever the furnace does kick on and furnace fan runs. If you have any other questions please contact us at 800-334-6011. Thank you

What is this red LED light on my Aprilaire 600 humidifier?

Wednesday, December 7, 2011 by Aprilaire Team
Consumer question:

Solenoid valve does not appear to open. Shut down furnace. Changed water panel. Adjusted furnace to call for heat. With blower on, about 1 minute, green "change water panel" light and red LED inside the control panel, both come on simultaneously. After about 1 second green light goes off. Red LED, marked D10, on the circuit board remains on. Moved control knob toreset/test position for one minute, and adjusted to previous "normal" humidification setting. Red LED stays on, and no water is being fed into evaporator. -Water to solenoid is "on." Any suggestions??

Aprilaires' response:

Thank you for your email regarding your model 600 Aprilaire humidifier. The red LED indicates the outdoor temperature terminals(ODT) are not receiving a temperature reading from the outdoor temperature sensor. The humidifier control will not function without the outdoor temperature reading. Our recommendation is to have your HVAC installer review the wiring and test the outdoor sensor and replace sensor if necessary.
