Perform Aprilaire Humidifier Annual maintenance like a boss!

Monday, April 22, 2013 by Aprilaire Team

For best performance, we recommend you replace the Water
Panel evaporator in your Aprilaire humidifier at least annually with
the exception of Models 400 and 400M, which should be changed at
least twice per heating season.

The “Change Water Panel” indicator light (Digital Control only) will blink
when it is time to change your Water Panel. See individual model instructions
for additional maintenance.

To purchase a new Water Panel:

• Visit estore.aprilaire.com

• Call the installer of your Aprilaire humidifier.

• Call your heating and air conditioning dealer.

• Use our “Dealer Locator” at: www.aprilaire.com

• Purchase only Genuine Aprilaire Water Panels to maintain best performance.

If your humidifier is equipped with a Digital Humidifier Control with Water
Panel change indicator, after replacing the Water Panel, turn the control
knob to the “Test/Reset” position until the “Humidifier On” light blinks to
reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure
to turn the control knob back to it’s original setting. If the “Humidifier On”
light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

Also review the periodic preventavtive maintenance in the owner's manual.

Is there a way to regulate the water control on the Aprilaire model 700 humidifier?

Thursday, February 28, 2013 by Aprilaire Team
Consumer question:
 
Is there a way to regulate the water control? I get a steady stream coming out of the drain line. Thank you!
 
Aprilaires' response:
 
Thank you for inquiring about your Aprilaire model 700 humidifier.

Your humidifier, when wired properly, will allow a stream of water to flow through the water panel only during the humidification cycle. If the humidistat is not requesting humidification, then the water should not be running through to the drain. The water flow rate into the model 700 is fixed to 6 gallons per hour, during the humidification cycle. The water flow down the drain depends on the evaporation effect within your environment, estimated between 4 to 4.5 gallons per hour.

I love my Aprilaire model 700A but I have a GPM question.

Friday, February 22, 2013 by Aprilaire Team
Consumer question:
 
Hello,

We had a 700A model humidifier installed about 5 months ago and it seems to work well. I am trying to find what the Gallons Per Minute (GPM) input is when the humidifier is running. I cannot find this information anywhere in the data sheets. It says that the drainage should be (as I calculated it from the FAQ) to be 0.05 to 0.1 GPM but not the input to the humidifier (I would assume this to be more than 0.1 GPM). What should the 700A humidifier be consuming in water input?

Thanks,
Nick
 
Aprilaires' response:

Hello Nick,

Thank you for contacting us. The feed rate for your humidifier is a 6 gallon per hour feed rate to the distribution tray. You should be able to fill a quart jar in 2.5 minutes to the distribution tray or fill a quart jar in 2 minutes 50 seconds for the water coming out of the drain of the humidifier. Is the humidifier mounted on the return or supply side of the furnace? Do you have a hot or cold water supplying the humidifier? The evaporative capacity for the humidifier is dependant on how much heat you are supplying to the humidifier. Supplying cold to a humidifier water mounted on the supply side get you a .75 gallons per hour evaporation, and supplying hot water to a humidifier mounted on the supply side gives you an evaporation rate of .9 gallons per hour. If you have any other questions please contact us at 800-334-6011. Thank you

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.

Can I run and Aprilaire 600 in manual mode?

Tuesday, February 19, 2013 by Aprilaire Team
Consumer question:
 
I WAS WONDERING HOW TO RUN THIS UNIT IN A MANUAL MODE. I SEE HE LEFT A DOUBLE PRONG THING TAPED TO THE FURNACE THAT SAYS MANUAL ON IT BUT I DONT KNOW WHERE IT GOES. THANKS FOR THE HELP
 
 
Aprilaires' response:

Dear Randy,

Thank you for your email regarding your model 600 Aprilaire humidifier. Your model 600 can be set up as an automatic or manual control. In automatic there is an outdoor sensor connected to the control which will allow the control to automatically adjust the humidity level as the outdoor temperature changes. In manual mode you will need to adjust the humidifier control as the outdoor temperature changes. If not, you may over humidify your home. If you choose to run in manual mode simply remove the outdoor sensor from the terminals labeled odt and connect the manul model sensor instead.


Thank you for giving us the opportunity to be of service

Blower Motor Cycling Issue

Monday, February 18, 2013 by Customers Sharing Stories

Consumer feedback:

I have the Model 700 with the Model 58 humidistat. The problem I'm having is that the humidistat is callingtne furnace to start the blower motor I guess because the humidity has fallen below what it needs to be. However, the blower motor comes on for like 10 seconds and the shuts off. It will repeat this cycle 100 times a day so I have to turn the humidistat off. It generally only does this during the day because the thermostat is set to a temp that generally doesn't require heat. The HVAC guy has replaced the humidistat already with no success. My furnace is an Amana prane model. What's going on with this? Thanks

Name: Ken

State: MD

 

Aprilaires' reponse:

Dear Ken,

Thank you for contacting us with regards to your model 700 Humidifier. Based on the information provided, it’s not clear how this humidistat has been wired. Normally, the model 58 humidistat does not have the ability to operate your furnace fan without an additional relay. It’s possible that this relay has not been wired properly. We would recommend that you have your HVAC guy contact us when he’s next on-site. We can provide troubleshooting assistance by phone.

We look forward to assisting you with this issue.

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.

I'm trying to decide between the 400, 600 and 700 Aprilaire whole house humidifiers? Please advise.

Wednesday, January 23, 2013 by Aprilaire Team

From: webmaster@aprilaire.com\



>>> Phyllis Kaplanek 02/20/12 15:21 >>>

Hello Dan,

Thank you for contacting Aprilaire.

Yes, the 400 does not drain, it will evaporate all of the water used.

The 600 uses no power, so would be less expensive to run than the 700.

When the 700 is operating, it is drawing air from the duct work, humidifies it, and blows it back into the duct work all in one spot. Also, yes, sometimes it has been reported that cold air would come out of the vents in the 700 during usage of the air conditioner.

It is difficult to offer 'utility expenses' since each home uses different amounts of water or electricity depending on the humidification needs.

Please let us know if you have any further questions.

Comments: I\'m trying to decide between the 400, 600 and 700 whole house humidifiers. I like that the 400 wastes no water and uses cold water. Does the fan in the 700 draw air in from the basement or is it sealed so it only pulls heated air from the duct? Would air conditioned air escape from the 700 into the basement during the summer?About how much energy does the fan use on the 700? Will this cost me like $20 more per year in electricity than the 600, for example? How much less would the 400 be in utility costs than the 600 or 700? Thank you!

Can I install the Aprilaire humidifier above the cooling coil and still get the same efficiency from the unit?

Monday, January 21, 2013 by Aprilaire Team

From: webmaster@aprilaire.com



>>> Phyllis Kaplanek 02/21/12 09:01 >>>

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.

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.
 
If you have any other questions please contact us at 800-334-6011. Thank you

My humidifier control is not working so well...what should I do?

Wednesday, January 2, 2013 by Aprilaire Team
Consumer questions:
 
The automatic control for my aprilaire model 600 is malfunctioning. To get it to work, I have to only move the knob slightly, but the next time the furnace kicks in, I will have to do this all over again. So basically, the unit is malfunctioning. What do I do?
 
Aprilaires' response:
 
Thank you for your email regarding your model 600 Aprilaire humidifier. The automatic humidifier control will operate your model 600 to achieve the set point the dial is set to. Once the set point is reached, the humidity level in your home has to fall below the set point before the humidifier control will again operate your humidifier. When you move the humidifier control dial to a higher setting, the humidifier will operate provided the furnace is running. This is normal operation. Based on the information you proved your automatic humidifier control is working as designed.

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.

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.

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.

Keep your Humidifier Running at Peak Performance by following these Annual Maintenance Tips

Thursday, October 18, 2012 by Aprilaire Team

For best performance, we recommend that you replace the Water
Panel evaporator in your Aprilaire humidifier at least annually with
the exception of Models 400 and 400M which should be changed at
least twice per heating season.

The “Change Water Panel” indicator light (Digital Control only) will blink
when it is time to change yourWater Panel. See individual model instructions
for additional maintenance.

To purchase a new Water Panel:

• Visit estore.aprilaire.com
• Call the installer of your Aprilaire humidifier.
This information is often found on your equipment.
• Call your heating and air conditioning dealer.
• Use our “Dealer Locator” at: www.aprilaire.com
• Purchase only Genuine Aprilaire Water Panels to maintain performance.

If your humidifier is equipped with a Digital Humidifier Control with Water
Panel change indicator, after replacing the Water Panel, turn the control
knob to the “Test/Reset” position until the “Humidifier On” light blinks to
reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure
to turn the control knob back to it’s original setting. If the “Humidifier On”
light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

Also review the periodic preventavtive maintenance in the owners manual.

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.

Why does the water run out of the bottom of the humidifier?

Tuesday, October 16, 2012 by Aprilaire Team

Consumer question:

Why does the water run out of the bottom of the humidfier. Just installed a new water panel.Could it be that too much water is going into the unit?
 

Aprilaires' response:

Thank you for your email regarding your model 700M Aprilaire humidifier. All Aprilaire humidifiers will use water not evaporated, to flush away minerals left behind from the evaporation process. Water draining is normal.
