Hello William,

Thank you for contacting Aprilaire.

Yes, you may install the humidifier above the cooling coil, or you may also install it on the cold air return duct. You really are not limited to where this unit can be installed. It would also be best to plumb hot water to the humidifier.

There is an 'orifice' installed into the water feed tube. The feed tube comes out of the solenoid, and brings the water into the humidifier, and deposits the water in the distribution tray at the top. The orifice is installed into the feed tube at the end that is inserted into the solenoid valve. That is the only metering device we have to monitor the water flow.

Please let us know if you have any further questions.

Comments: I would like to install a Model 700 Humidifier on my forced air gas furnace that has a cooling coil in the furnace. Due to the location of the cold air return ducts, I'm not able to locate the unit in the plenum in line with the coil as instructed in the manual. I would have to move the unit up above the coil to have enough room between the plenum and duct work. My question is --Can I install the unit above the cooling coil and still get the same efficiency from the unit? Also, does the solenoid on the unit control the 6GPM the unit used and is it preset to do that?

Hello Jeff,

Thank you for contacting Aprilaire.

The yellow orifice goes into the water feed tube. The end that the orifice goes into will be the end that is then inserted into the solenoid valve, at the outlet end of the solenoid valve.

Please let us know if you have any further questions.

My Aprilaire humidistat is on the wall, where is it testing the humidity level?

Friday, January 18, 2013 by Aprilaire Team

Consumer question:

I installed my humidistat on the wall in my house and was wondering which location is more effecient / effective at reading the humidity level...on the wall or on the return duct at the furnace.

 

Aprilaires' response:

Thank you for your email regarding your model 700M Aprilaire humidifier. When the humidistat is installed in the living area it will control the humidity level based on the conditions in that specific area. If the humidistat is installed on the cold air return the humidistat will control the humidity level based on the humidity coming through the cold air return, This air is a mixture of all the air in your home. The humidistat can be located in either area. The desired location has to do with where you are most concerned with the humidity level.

 

When should my Aprilaire model 700 humidifier run?

Thursday, January 3, 2013 by Aprilaire Team
Consumer question:
 
Since my model 700 was installed last winter, I've noticed it sometimes runs even if the heater isn't running. Also, sometimes, if the heater is running, the humidifier does not. It seems to run completely independently of whether the heater is running or not. Is this normal?
 
Aprilaires' response:
 
Thank you for contacting us. The humidifier does not regularly run independent of the furnace when wired to turn on and off with the furnace heat call. If you turned the humidistat down when the humidifier was running, does the humidifier turn off? If the humidifier stays on when the humidistat is turned down, then you would have a bad solenoid. If the humidifier turns off then you have a good humidistat and good solenoid.

Do you have a digital humidistat that you are controlling the humidifier with? The digital humidistat has a blower activation switch on it and you might have that in the on position. Turning the blower activation switch to the off position should solve your problem of the humidifier running in these different times.

If you have a manual control to wired to the humidifier, then you would need to have your service contractor trouble shoot the current sensing relay that would be wired between the humidistat and humidifier.

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.

 

Should my Aprilaire humidifier run ONLY when my furnace is running?

Monday, October 29, 2012 by Aprilaire Team
Consumer question:
 
I have an Aprilaire model 700 and I assume it's normal to turn on my heater's blower in automatic mode to raise humidity? When I turn it down from 5 to 3, the blower doesn't turn off. Is that normal?
 
 
Aprilaires' response:
 
Thank you for contacting us regarding your model 700 humidifier. When installed and wired properly, the humidifier should only turn on after the blower has been activated due to a heat call or fan call from the thermostat. If your control has the optional blower activation function, it may extend the blower and humidifier run time after the heat call has been satisfied. However, if you are using the blower run extension, it should turn the blower off if you lower the humidity level. We may need more information to fully understand your particular situation.

Additionally, to better understand the functionality of your unit, you have the option to call our technical support department at 1-800-334-6011 to discuss it with one of our technicians over the phone.

Faulty wire connection?

Wednesday, October 17, 2012 by Aprilaire Team

Consumer question:

Hi: I have the 8570 thermostat pn 61000229 rev c with a 700a humidifier; ADHC model 58; 61000501 rev b.
The adhc is wired to the 8570 for activation. The supplied outside sensor is also used. It works but intermittenly the 8570 screen goes blank while operating and causes the adhc "call dealer for service" light. the E4 code appears on the adhc. I had the heating tech out for annual service and could not find anything wrong. The only other symtom that I noticed was it occurs in the temp range freezing or above. During continous freezing weather, it did not seem to need to be reset as much.
I have rechecked the wiring between the 8570 and adhc and it is correct. The intermitten screen blank on the 8570 makes me believe that either the unit is faulty or an intermitten power loss.  Any thoughts?

 

Aprilaires' response:

Thank you for including Aprilaire as part of your home comfort system.

The description you have given us sounds as though there is a problem with the communication between the 8570 thermostat and the model 58 humidistat. You may want to recheck that all the connections at the ADHC and 8570 are snug, including the sensor to the outdoors. If the connections are snug and the fault reoccurs, you may remove the "A" and "B" wires between them and determine if the fault reappears. If it does not then the problem would probably be a broken wire.

If you have further questions, or need more assistance, feel free to contact us.

 

Replacement question on my Aprilaire Humidifier

Thursday, September 27, 2012 by Aprilaire Team

Consumer question:

I plan on replacing my (2) 760 Humidifiers with two new 700 humidifiers and would like to receive installation instructions, particularly the wiring. Can you assist - I could not find anything on the site.

 

Aprilaires' response:

The 700 would be the correct replacement for the 760 humidifier. They are the same size and fit into same opening in the ductwork. The only difference would be how they wire into the humidistat. Also, each humidistat installs differently from each other.

All installation instructions come with the humidifier and humidistat.
 
Thank you!

 

How do I get more humidity out of my humidifier?

Friday, August 24, 2012 by Aprilaire Team
Consumer question:
 
Just installed a 600 unit. We had to turn blower on because furnace time alone was not increaing the RH enough. Will the blower shut off once the desired RH is reached or do I need to flip the switch? My concern is that without the blower the desired RH might not be attained.
 
Aprilaires' response:
 
Thank you for contacting us regarding your model 600 humidifier. If the control with your model 600 is the model 60 automatic digital humidistat control (ADHC), you have an optional blower activation built into the control. When wired properly, the model 60 can extend the blower run time to allow your humidifier to continue to run after a heat call has been satisfied. Once the humidity set point has been satisfied, the blower activation will turn off automatically.

If your control does not offer the blower activation or you are not using the available blower activation, the control does not have the capability to turn off the blower when the humidity set point has been reached. In this case the blower would need to be turned off manually.

Additionally you have the option to call our technical support department at 1-800-334-6011 to discuss this with one of our technicians over the phone. Our tech support department is available Monday through Friday, 7 am to 5 pm CST.

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. 1-800-334-6011.

 

My Aprilaire humidifier control is showing an E1 error? Help!

Monday, June 11, 2012 by Aprilaire Team
Consumer question:
 
I have an 600 model humidifer that has been working fine since installed. I noticed my house was dry this past week and discover an E1 error on the humidstat. I reset the unit a few times but the error keeps coming back.


Aprilaires' response:

Thank you for contacting us.
Unfortunately an e1 error code would indicate an issue with the relative humidity sensor on the back or an issue with the circuit board on the control.
The humidistat would need to be serviced by the point of purchase or another local dealer.
Here is our dealer locator if you need to find a recommended local dealer:

I have manual control for my whole house humidifier. I've been noticing water on the windows in the morning.

Saturday, May 12, 2012 by Aprilaire Team
Consumer question:
 
I have manual control for my whole house humidifier. I've been noticing water on the windows in the morning. When I look at the humidistat it is set for 32% (doesn't say RH but thats what I assume). I got another Aprilaire humistat that just measures RH and put it on top of my existing control. Where the existing control indicates about 32%(5% hysterisis) the standalone unit indicates 44%RH. How do I know which is correct and what do I do if my existing manual control is wrong? IS there a way to clean or calibrate it?
 

Aprilaires' response:

Thank you for your email regarding your Aprilaire humidistat. If you turn the dial from left to right you should hear two clicks. The actual humidity in your home will be the area between the two clicks. For example, if the humidistat clicks at 30% and 36% your actual humidity would be 33%. There is not a way to calibrate the humidistat. It is unclear from your email if the original humidistat is an Aprilaire humidistat, so it is difficult to say if it is out of spec. The accuracy of our Aprilaire manual humidistats are +/- 5%

The moisture on your windows is due to the surface temperature of your windows reaching dew point. This occurs when there is more humidity in the home than what the home can hold based on the current outdoor temperature. As the temperature outside drops you want less humidity in your home. For example when the outdoor temperature is 20F or above we recommend 35% humidity at a room temperature of 70F. If the outdoor temperature drops to 0F you'll want 25%.

Thank you for giving us the opportunity to be of service.

My Aprilaire model 760 humidifier that has worked great for the last 11 years has a short

Thursday, May 10, 2012 by Aprilaire Team

Consumer question:

My Aprilaire model 760 humidifier that has worked great for the last 11 years has a short that apparently cannot be repaired. So what would it cost to get a new one that will fit my furnace exactly like my 760 did. Also the cost of a new one, or can mine be sent in for repair.

 

Aprilaires' response:

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

I am sorry to hear that your model 760 has failed after 11 years of service. I am please to let you know that you local heating and air conditioning company can assist you in obtaining a replacement for your model 760. Our current model 700 humidifier would replace the model 760 for area coverage, the dimensional size may vary slightly.

 

What is the minimum water temperature to supply an Aprilaire 350 humidifier?

Tuesday, May 8, 2012 by Aprilaire Team
Consumer question:
 
What's the minimum water temperature needed to supply this Aprilaire model 350 humidifier unit? We want to reduce the water temp for the summer so it doesn't heat the house while it runs. Here in Denver we still need the moisture all year around.

By the way, do you make a in-the wall ultrasonic unit with a humidistat, that can run from filtered water that removes minerals and chlorine?
 
 
Aprilaires' response:

Thank you for your email regarding your model 350 Aprilaire humidifier. The minimum water temperature for our self contained humidifiers is 140F. This is required in order for the evaporation process to take place. When the hot water flows over the water panel, the water evaporates off the water panel and into the room temperature air moving through the water panel. Lowering the water temperature will reduce the amount of humidification produced. The water to the humidifier can be hard or softened but should not be from a reverse osmosis system. We do not manufacture ultrasonic humidifiers.

 

What is the replacement for the 2120/2140?

Monday, May 7, 2012 by Aprilaire Team
Consumer question:

We had our A/C system replaced last year. We had an Aprilaire filter system installed at the recommendation of the contractor. He said that the filters were Aprilaire 2120/2140 and a Humidifier Panel 400. What is your current replacement for these. I do not see them on any site selling your product.

Aprilaires' response:

Thank you for contacting us regarding replacement media for your Aprilaire products. The models 2120 and 2140 are two different air cleaners and would take different filter media. Please follow the links below for more information on the filter media for the two air cleaners:

How can I tell the difference between the old aprilaire 400 series humidifiers?

Monday, May 7, 2012 by Aprilaire Team
Consumer question:
 
How can I tell what model I have? (please add this question/answer to your FAS's).

My unit is probably at least 25 years old. I am having a problem with it (leaking water coming from unit's housing), and would like to understand which model I am dealing with.

I have a unit that is installed on ductwork associated with the furnace. The unit is drained by a flexible tube that goes into a pump (on the floor) that evacuates the excess water to a nearby sink. The unit uses warm water.

The rheostat/control is installed on ductwork as well, about 3-4 feet away from the unit. The Rheostat is a dark brown/black control knob, in the middle of a rectangular panel that is also dark brown/black. All the printing on the rheostat's panel (that was once a faint gold perhaps) is worn away, except the '25' at the top/middle of the dial, and - in the upper right- the lettering 'aire.'

Some pages from the original manual were pasted on the inside of a cabinet door in the basement by a previous owner (until today I had not known what they were for.). The instructions say that the Summer Shut-off instructions are to turn the dial to 25. I was unable to find a manual on your website that contains those instructions.

However, from the pictures in http://www.aprilaire.com/themes/aa/en/manuals/Humidifiers_Owners_Manual.pdf, it appears like the models shown on pages 13 and 14 (Models 440, 445-448).

How can I tell which model it is? thank you.
 
 
Aprilaires' response:

Thank you for your email regarding your Aprilaire humidifier.
The following is the best way to tell the difference between the model 440 and the model 445-448. The 445-448 will have a thumb screw on the bottom of the Humidifier to hold on the reservoir. The 440 does not have a thumb screw because it does not have a reservoir.
Turn your Humidistat knob clockwise until it stops (to the off position) to turn your Humidifier off. You will have to set it to the desired percent when your humidity levels begin to decrease.

 

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.

 

There's a knock whenever the humidifier comes on or shuts off. What is the cause?

Wednesday, March 7, 2012 by Aprilaire Team

Consumer question:

There's a knock whenever the humidifier comes on or shuts off. What is the cause?

Aprilaires' response:

Thank you for contacting us with regards to your model 700 Humidifier. The noise you hear is the humidifier's solenoid valve (water valve) opening or closing. Normally, this valve makes a slight 'click' noise when doing this, but water pressure and the build up of water scale inside the unit can increase this noise. As a test, try turning off the water to the humidifier and then use the humidistat to turn the humidifier on and off. Listen for changes in the noise. Typically, the noise is quieter without any water pressure, but pressure is required to feed the correct amount of water through the unit.
Speak to your contractor about possible remedies if the noise becomes excessive. Anything from cleaning the valve to adding sound-insulating foam rubber to the valve can help dampen the nosie. In some cases, replacing the copper tubing with steel-braided rubber tubing or installing a shock-arrestor can help dampen the noise by absorbing the impact the water makes when the valve closes.

 

 

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.

Can an in-line fan be added to my Aprilaire humidifier?

Wednesday, February 29, 2012 by Aprilaire Team
Consumer question:
 
Can I add an in-line fan to the humidifier bypass duct in order to increase the humidity?
 
Aprilaires' response:

Thank you for contacting us with regards to our model 400 Humidifier. This humidifier requires between 60-100 CFM to operate properly. If the air provided to the humidifier is lower than 60 CFM, an in-line fan may help increase the humidification rate, but it should only run with the furnace. As a drainless model, it does not humidify well without a source of heat to evaporate the water.
