Lots of water running down the drain tube, is that correct?

Thursday, June 28, 2012 by Aprilaire Team
Consumer question:
 
I had a model 700 Aprilaire humidifier installed yesterday and have a couple of questions;

1) it seems to have a lot of water when running coming out of the drain tube, is that normal?
2) I had to install the hunidifier on the return side becuase there was no room on the feed side of the furnace. I put the thermostat on the return side also but the reading goes way up and then back down when its operating when it kicks on and off. Should I put the thermostat on the feed side so its not on the same side as the humidifier? Its running in manual mode right now, I have to run the sensor outside adn my basemnet is finished so thats going to be a challenge.

 
Aprilaires' response:
 
Thank you for choosing the Aprilaire line of humidifiers for your home comfort system.
 
The amount of water that is discharged down your drain should be approximately 3 gallons per hour. Your description of the extreme humidity swings when the unit is cycling on and off lead me to the conclusion that the humidifier control may be mounted too close to the humidifier, or is mounted between the humidifier and the furnace, allowing for the humidifier output to affect the sensing of the control. It is recommended , in the installation guide that the control should be mounted at least 6" upwind of the humidifier.

Should my Aprilaire Humidifier be hooked up to hot or cold water?

Friday, June 8, 2012 by Aprilaire Team

Consumer question:

I have a Aprilaire 600m model and should I conect the water supply to the hot or cold line.

 

Aprilaires' response:

Thank you for your email regarding your model 600M Aprilaire humidifier. Your Aprilaire humidifier will operate on hot, cold hard or soft water. We do however recommend hot water as it will increase the evaporative capacity of the humidifier. Hot water will also allow you to operate your humidifier during a fan call. A heat source is required for the evaporation process. During a fan call the only source of heat is hot water.

 

 

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.

 

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.

 

No water comes in to the model 500 aprilaire humidifier when running. What could be happening?

Wednesday, May 9, 2012 by Aprilaire Team
Consumer question:
 
No water comes in to the model 500 aprilaire humidifier when running. Could it be a problem with the solenoid valve??


Aprilaires' response:

Thank you for contacting us.
No water could be an indication of an issue with the solenoid valve.
If you have an Automatic Control try putting it into test mode:

A. No click at the solenoid valve indicates an electrical problem. Contact the heating and air conditioning dealer to further check the electrical components of the Aprilaire Humidifier.

B. If the solenoid valve makes a click sound and there is no water draining from the unit, this would indicate the flow of water is being obstructed.

1. To determine if water flow is being obstructed, turn the dial of the humidifier control to the off position. The first location to check for an obstruction would be at the saddle valve located on the water line supplying water to the humidifier. When checking the saddle valve, make sure it is completely open. This can be done by turning the valve all the way to the left. If anything is clogged, it can be dislodged by turning the saddle valve all the way to the right and back to the left. Once this is done, turn the humidifier control dial above the click point and water should be coming out the drain line.

2. If water is still not coming out of the drain, check the orifice and in-line strainer to make sure they are not clogged. The orifice is located in the tube on the outlet side of the solenoid valve and the in-line strainer is located on the inlet side of the solenoid valve (see attached). The orifice may be cleared by inserting a needle through the small opening. The strainer may be cleaned by running it under warm water to dislodge deposits or replace it. After clearing and re-installing the orifice and strainer (be sure to double wrench all water connections), turn the humidifier control dial above the click point and water should be coming out the drain line.

 

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.

 

I need humidity in the Summer, what should I do?

Wednesday, April 25, 2012 by Aprilaire Team
Consumer question:
 
My heating/air cool unit is now controlled by a new thermostat that allows fan circulation about 35% of the time whether the heat or cooling is running or not. Will the humidifier work when the fan is on whether it is on heating or cooling? I live in an area which humidity averages about 12% during the summer. I need to add humidity during those times.
 
 
Aprilaires' response:

Thank you for that very good question regarding the Aprilaire humidifier operation.

The answer to your question depends on the type of humidity control that was installed with the humidifier. In the event that the humidity control was the type that used an outdoor temperature sensor to regulate the humidity, then the humidifier would not add humidity in the summer months. this type of control would disable the humidifier when the outdoor temperature would go above 60 degrees. If the humidity control does not use the outdoor temperature sensor, then you may be able to humidify during the summer months. Just be aware that the air conditioning system will remove some humidity during its normal operation; which would take longer to bring the humidity level up.

 

Summer time use of my Aprilaire Humidifier Model 700?

Tuesday, April 24, 2012 by Aprilaire Team
Consumer question:
 
I recently moved into home that has Aprilaire Automatic Humidifier Model number 700. My question is during the Summer time when I switch the heat off and turn on the A/C at the thermostat. Will the Humidifier stay off or do I need to somehow turn the unit off?
 
Aprilaire response:
 
Thank you for contacting Aprilaire.

To live in Indiana, the humidifier would typically not bother to come on during summer, as nature gives us more humidity than we need. Any time the level of humidity is higher than the selected level, (or max of 45%) the humidifier will not come on.

Some people, just to make sure, will go ahead and turn down the humidistat to 'off' or at least the lowest setting. Then, for the same reasons as listed above, the humidifier will not come on.

Please let us know if you have any further questions.

Summer's High Humidity Affects Indoor Air Quality

Monday, April 2, 2012 by Aprilaire Team

Summer is almost here and with it we welcome the long-awaited warm weather but not the sticky, high levels of humidity that often come with it.  High humidity affects the quality of indoor air and can affect the health of you and your family in a variety of ways.

High humidity levels can cause mold, encourage dust mites which are a major cause of allergies, and cause a hot of problems in the home that can affect your physical health.  Visible signs of high humidity levels include condensation on windows, peeling wallpaper, damp patches on walls and ceilings, a musty smell and dampness.  But there are also numerous problems that go undetected because you can not see or smell them. 

A few of the most common health effects of too much moisture in the home include the following:

Dust mites:  At least 10 percent of the population suffers from a dust mite allergy.  Half of American homes have enough bedding with enough dust mite allergen to cause allergies.. Of these homes, 24 percent had levels that were five times greater than the threshold to cause allergic reactions.

To control dust mites, experts recommend regular cleaning to reduce dust, as well as encasing mattresses, box springs and pillows in allergy-free cases.  The more dust-free the home, the less likely it will be able to support significant populations of allergen0causing dust mites.  Some of the symptoms associated with it include sneezing, itchy, watery eyes, nasal stuffiness, runny nose, stuffy ears, respiratory problems, atopic dermatitis and asthma.

Bacteria: you can't see or feel bacteria but they live on countertops, table surfaces, carpet, pillows, mattresses and just about anywhere people are.  Bacteria also grow profusely when there is plenty of moisture present.

Formaldehyde: When humidity levels are high, products such as furniture, cabinets, building materials and even some latex paints then to release formaldehyde into the air at a faster rate.  Studies have suggested that people exposed to formaldehyde levels ranging from 50 to 100 parts per billion for long periods of time are more likely to experience asthma-related respiratory symptoms, such as coughing and wheezing.

If you suspect that the air in your home is too moist, be sure to vent the areas that create moisture, like the show or bathroom.  You may also consider a whole home dehumidifier like the Aprilaire Model 1710A, 1730A,1750A or the 1770A.  The Aprilaire dehumidifiers can work independently or in tandem with the heating and cooling systems to remove extra moisture from your home.  A system like this will allow homeowners to achieve the EPA recommended humidity levels in the house of 30-50 percent.

What Everybody Ought to Know About Whole Home Air Cleaners - they are Proven to Protect and Even Improve Health

Monday, April 2, 2012 by Aprilaire Team

The air in American homes is increasingly contaminated and polluted, and now studies have linked poor indoor air quality to the dramatic rise in not only allergy and asthma symptoms, but also a variety of other health issues, including heart disease, stroke and blood clots.

Studies are emerging that prove poor indoor air quality can cause or contribute to a variety of symptoms and medical issues.  While individuals with pre-existing medical problems such as asthma, chronic obstructive pulmonary disease (COPD) and allergies are at most risk from poor indoor quality, the medical literature demonstrates that even those in a good state of health are negatively affected.

The latest study conducted by scientists from Denmark and Sweden, published in the American Journal of Respiratory and Critical Care Medicine, reveals that poor indoor air adversely affects the performance of blood vessels in humans leading to cardiovascular disease.  The study also found that indoor air filtration greatly reduced the amount of ultrafine, fine and coarse air particles in the homes tested, which was associated with an actual improvement in the microvascular function of the study participants.

In an effort to protect public health and combat airborne invaders, Aprilaire, a leading manufacturer of indoor air quality products, is urging consumers nationwide to consider whole-home air cleaners as part of a modern and integrated approach to managing their indoor environments. Homeowners can be sure that a whole-home air cleaner works to permanently trap the airborne contaminants that most affect health and aggravate allergy and asthma symptoms, moving clean and comfortable air throughout every room of the home, all while operating silently and out of sight.

While the medical community acknowledges the benefits of clean air in the home, consumers often find themselves disappointed with the options available at local home improvement centers where portable, do-it-yourself air cleaning units are sold.

“We know through research that most people buy portable air cleaners to help alleviate some sort of respiratory issue, this cannot be accomplished with one portable air cleaner for an entire home,” said Mike Rimrodt, marketing director for Aprilaire. “In fact, most homes require four or five portable units or more too clean the air throughout the entire home and still don’t do as good a job,” notes Rimrodt. “When comparing performance, installation and maintenance factors, and overall cost, a whole-home air cleaning solution is ideal for families who want to ensure healthy, clean air in every room and get the best value for their dollar.”

Whole-home air cleaners permanently trap the airborne contaminants that can aggravate health and allergy and asthma symptoms. In a recent standard industry test, the Aprilaire 5000 achieved 99 percent efficiency against airborne particles. The unit captures and kills virtually all contaminants including those that most affect personal health—viruses, bacteria, spores and allergens 24 hours a day, seven days a week, 365 days a year.

Aprilaire also offers homeowners a one-of-a-kind air cleaner control that allows them to actively clean the air in their entire home based on personal preference and event triggers. A simple-to-program thermostat features Event-Based ™ Air Cleaning:

  • Constant Cleaning:  air cleaner is active for 24 hours a day seven days a week
  • Automatic:  air cleaner will run a minimum of 30 minutes per hour
  • Event Clean:  air cleaners will run for three hours continuously and then turn off
  • Allergies:  air cleaner will run continuously for 24 hours and then turn off

Event-Based Air Cleaning also provides other conveniences such as indicators that air cleaning is taking place as well maintenance reminders.

Aprilaire Periodic Preventative Humidifier Maintenance

Monday, April 2, 2012 by Aprilaire Team

Periodic Preventative Maintenance

  • NOTE: Periodic inspection and preventive maintenance of your total heating system is important for efficient and safe operation. Your heating contractor should include humidifier service at the same time. All models are equipped with an in-line water strainer and orifice as shown below. These parts should be inspected and cleaned periodically to assure continued proper unit performance.

Aprilaire Humidifier Recommended Annual Maintenance

Monday, April 2, 2012 by Aprilaire Team

Recommended Annual Maintenance

  • The water panel should be changed once a year, with a few exceptions.
    • The model 400 has a panel that should be changed twice a season
    • If extremely hard water is used in any Aprilaire humidifier, the panel should be changed more frequently than once a season. 
    • The water panel cannot be cleaned because it has a special coating that helps the water adhere to the panel while the air is passing through it.  Without the coating, more water will go down the drain and less will be converted into a vapor.
  • Drain line
    • Detach the drain line from the drain spud at the bottom of the unit. 
    • Bend it at the various points to loosen calcium deposits which may have formed on the inside of the line, and flush it with pressurized water. 
    • You can also pour bleach through it prior to the water.  This will kill any micro-organisms that happen to be living in the drain line. 
    • The drain line can be replaced should it prove difficult to clean. 
  • Feed tube
    • Detach the tube from the nozzle at the top of the unit, and unscrew the end of the solenoid valve at the other end of the feed tube. 
    • Run high pressure water through the tube and replace. 
    • When reconnecting the feed tube, remember to double wrench the connections to prevent leaking.
  • Inside of unit
    • Look for any mineral deposits on the Scale Control Insert after removing the water panel, and get rid of them by wiping the insert with a damp towel or rag.  They should come right off. 
    • If there are deposits on the inside of the cover, or in the case of a 700, on the fan blade, it may be indicative of a larger problem known as entrainment.  ()
    • Do not remove granulated coating on the distribution tray – not an issue with the new ones. 
      • The granular coating is there to break up the surface tension of the water.  This allows water to flow evenly through all of the openings in the water distribution tray. 
      • The newer trays have a fabric along the bottom of the tray which does the same thing as the granular coating.  The difference is the customer doesn’t have to worry about scraping off the fabric.
  • Hard or Soft Water
    • Aprilaire offers total flexibility in the installation of our humidifiers in that they will operate properly with either hard or soft water. Connecting to hard water may leave mineral deposits on the water panel that are scaly and hard in nature. Connecting to soft water may leave mineral deposits that are fluffier in nature. The bottom line is the water panel will typically last a full heating season using either type of water.  When extremely hard water is used in the humidifier, maintenance should be performed approximately every six months.

Aprilaire Model 5000 EAC Air Cleaner is humming?

Thursday, March 29, 2012 by Aprilaire Team

Consumer question:

Why I started to hear humming noise when I turn on the Aprilaire Air Cleaner model 5000? The technician from Sears helped me to replace the filter in December 2011, but shortly after that, I start to hear this annoying noise and worry about the possible health risk it prsents to my family.

Does this electric humming/hissing really matter to human health? If so, whom should I contact?

 

Aprilaires' response:

Thank you for your email regarding your model Aprilaire Electronic air cleaner.
Under normal operation there is electricity passing through the door of the model 5000 into the cabinet just like a plug into an outlet. This can sometimes be audible but it does not pose any health risks.

If you are feeling that the noise is coming from the HVAC equipment call your HVAC specialist and have them give us a call when they are looking over the equipment.

 

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.

 

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.

 

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.
