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.

Remodeling Your Home? Have You Considered Indoor Air Quality?

Remodeling Your Home? Have You Considered Indoor Air Quality?

Ventilation for Homes

In general, you should address the following issues when remodeling your home.

Radon

Lead

Moisture Control

Ventilation

Asbestos

Combustion Appliances

Air Ducts

Energy Efficient Improvements

Pest Control

Painting

Volatile Organic Compounds (VOCs)

If too little outdoor air enters a home, pollutants can sometimes accumulate to levels that can pose health and comfort problems. Likewise, one approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming in.

Outdoor air enters and leaves a house by: infiltration, natural ventilation, and mechanical ventilation. In a process known as infiltration, outdoor air flows into the house through openings, joints, and cracks in walls, floors, and ceilings, and around windows and doors (air may also move out of the house in this manner — this is called exfiltration). In natural ventilation, air moves through opened windows and doors. Air movement associated with infiltration and natural ventilation is caused by air temperature differences between indoors and outdoors and by wind. Finally, there are a number of mechanical ventilation devices, from exhaust (vented outdoors) fans that intermittently remove air from a single room, such as bathrooms and the kitchen, to air handling systems that use fans and duct work to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the house. The rate at which outdoor air replaces indoor air is described as the air exchange rate. When there is little infiltration, natural ventilation, or mechanical ventilation, the air exchange rate is low and pollutant levels can increase.

Unless they are built with means of mechanical ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can "leak" into and out of the home may have higher pollutant levels than other homes. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a home, pollutants can build up even in homes that are normally considered "leaky."

Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air-conditioner with the vent control open increases the ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants, including moisture, directly from the room where the fan is located and also increase the outdoor air ventilation rate.

Ideally, new homes will be built to minimize leakage to control energy loss, improve comfort, and minimize the transport of moisture and pollutants through the building shell. These homes should then also have mechanical ventilation to remove pollutants generated in the home and provide outdoor air in a controlled manner. Whether a mechanical ventilation system makes sense in your existing homes depends on the house, your existing heating, ventilation, and air-conditioning (HVAC) system, and the changes you have planned. You should discuss this with your HVAC contractor. A local Weatherization office, or building performance contractor, might also be able to help you with this decision or point you to local experts.

How much ventilation do I need?

The American Society of Heating, Refrigeration and Air-Conditioning Engineering, or ASHRAE at www.ashrae.org provides procedures for determining whole-house ventilation rates in its Standard 62.2, "Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings". The standard also provides requirements for exhaust ventilation for kitchens, bathrooms, and other point sources, such as clothes dryers and venting for fuel-burning appliances.

Harmful Effects of Mold

Thursday, October 18, 2012 by Aprilaire Team

Harmful effects of molds

The type and severity of health effects that result from molds exposure is widely variable among different locations, from person to person and over time.

Although difficult to predict, exposure to molds growing indoors is most often associated with the following allergy symptoms:

  • Nasal and sinus congestion
  • Cough/sore throat
  • Chest tightness
  • Dyspnea (breathing difficulty)
  • Asthma (or exacerbation of it)
  • Epistaxis (nosebleed)
  • Upper respiratory tract infections
  • Headache
  • Skin and eye irritation

 

Indoor molds exposure leads mostly to upper respiratory tract symptoms

Long-term exposure to indoor molds is certainly unhealthy to anyone, but some groups will develop more severe symptoms sooner than others, including:

  • Infants and children
  • Elderly people
  • Individuals with respiratory conditions, allergies and/or asthma
  • Immunocompromised patients

Some indoor molds are capable of producing extremely potent toxins (mycotoxins) that are lipid-soluble and readily absorbed by the intestinal lining, airways, and skin. These agents, usually contained in the fungal spores, have toxic effects ranging from short-term irritation to immunosuppression and cancer. (Photo: Mold growing behind wallpaper)

More severe symptoms that could result from continuous human exposure to indoor mycotoxigenic molds include:

  • Cancer (aflatoxin best characterized as potential human carcinogen)
  • Hypersensitivity pneumonitis/pulmonary fibrosis
  • Pulmonary injury/hemosiderosis (bleeding)
  • Neurotoxicity
  • Hematologic and immunologic disorders
  • Hepatic, endocrine and/or renal toxicities
  • Pregnancy, gastrointestinal and/or cardiac conditions

It is important to notice that the clinical relevance of mycotoxins under realistic airborne exposure levels is not fully established. Further, some or much of the supporting evidence for these other health effects is based on case studies rather than controlled studies, studies that have not yet been reproduced or involve symptoms that are subjective.
(Photo: Black mold spores micrography)

Among the indoor mycotoxin-producing species of molds are Fusarium, Trichoderma, and one that, although less commonly isolated, became notorious during the past decade, Stachybotrys atra (aka S. chartarum, black mold). Between 1993 and 1994, there was an unusual outbreak of pulmonary hemorrhage in infants in Cleveland, Ohio, where one kid died. Researchers found that the kids’ homes had previously sustained water damage that resulted in molds contamination, and the quantity of molds, including S. chartarum, was higher in the homes of infants with pulmonary hemorrhage than in those of controls. (Photo: Stachybotrys growing on Potato Dextrose Agar (PDA))

It was this Cleveland event that initiated the headline news of Stachybotrys. The American Academy of Pediatrics produced guidelines in the wake of the outbreak. Other incidents involving kids in Stachybotrys-contaminated water-damaged school buildings have captured headlines as well, with children becoming symptom-free after being removed from those environments.
Article from the Fargo Forum newspaper, North Dakota (5/1/1997)

The role of S. chartarum in pulmonary hemorrhage in the Cleveland incident and in human health in the indoor environment is not clear though. There is not enough evidence to prove a solid causal relationship between S. chartarum and these health problems. Actually, in 2000 the CDC released two reports critical of the study conducted in Cleveland and concluded that the association between S. chartarum and acute pulmonary hemorrhage was not proven.

While case studies certainly indicate the possibility or even the plausibility of an effect from molds exposure, such studies by their nature cannot address whether the effect is common or widespread among building occupants. Results from studies that have not been reproduced may be spurious or have yet to be confirmed by well-designed follow up studies. (Photo: Moldy humid walls in a closet space)

In large epidemiologic studies, general symptoms have been associated with moisture damaged and presumably moldy buildings. Many of the reported symptoms are subjective and difficult to quantify. Results are confounded by the fact that the association is general, and mold is not the only possible cause of the symptoms. Neither condition proves that mold is NOT a cause.

In any case, molds growth in the indoor environment should be considered unacceptable from the perspectives of potential adverse health effects and building performance.

Dose-response

There is almost a complete lack of information on specific human responses to well-defined exposures to molds contaminants. There is currently no proven method to measure the type or amount of mold that a person is exposed to, and common symptoms associated with molds exposure are non-specific, aggravated by the facts that molds are present everywhere in the environment and that responses to exposure vary greatly among individuals. (Photo: Heavy mold growth on the underside of spruce floorboards)

There are no accepted standards for molds sampling in indoor environments or for analyzing and interpreting the data in terms of human health. Most studies are then based primarily on baseline environmental data rather than on human dose-response data. Neither OSHA or NIOSH, nor the EPA has set a standard or PEL for molds exposure.

Mold growth on air diffuser in ceiling
Miller et al. (1988) stated that it is reasonable to assume there is a problem if a single species predominates with >50 CFU/m3, that <150 CFU/m3 is acceptable if there is a mix of benign species, and that there is no problem when up to 300 CFU/m3 of Cladosporium or other common fungi is isolated. There is no source material to support these assertions, as few inhalation studies have been conducted.

What Types Of Mold Are Considered Toxic Mold

"Toxic mold" is a term that is used to describe types of mold that are considered deadly to humans. Most people believe that the name refers to one particular species of mold; however, it encompasses hundreds of species, a small fraction of which are not very harmful to the human body. Black mold is commonly used as a name for the most harmful mold species, which happen to be black in appearance. However, even molds of a different color can be toxic to the human body.

Any place that is dark and where there is an accumulation of moisture, is a potential breeding pool for mold. Mold can grown on almost any organic surface as long as moisture and oxygen are present. When large amounts of moisture build-up in buildings, or building materials mold growth will occur. It is virtually impossible to remove all indoor mold and mold spores, but it is possible to manage.

People are exposed to some amount of mold everyday. When mold is growing on a surface, spores can be released into the air where a person can then inhale them. A person who is subject to inhaling a large amount of these spores may be subject to some medical damage.

There are five categories of toxic mold. They are Cladosporium, Penicilium, Fusarium, Aspergillus, and Stachybotrys. Some of the species included in these categories may only cause hay fever-like allergic reactions, while others can cause potentially deadly illnesses. All five of these mold families can be found lurking indoors, in damp spaces. Each has its own particular characteristics that can greatly affect whatever organism or material it contacts. Indoor mold is not always obvious. Mold can manifest on hidden surfaces, such as wallpaper, paneling, the top of ceiling tiles, and underneath carpet.

Stachbotrys

The toxin produced by Stachybotrys chartarum is the most deadly. It has been tied to diseases as minor as hay fever, to those as serious as liver damage, pulmonary edema, and in the most severe cases, brain or nerve damage and even death. It has also been linked to severe illness in infants. Those with compromised immune systems, small children, and the elderly are highly susceptible to illness when they come in contact with this species of mold. Some symptoms associated with exposure to Stachbotrys include:
respiratory issues
nasal and sinus congestion
eye irritation
sore throat
hacking cough
chronic fatigue
central nervous system issues
aches and pains

Cladosporium, Fusarium, and Penicillium

These mold families have been connected to illnesses such as nail fungus, asthma, and also infections of the lungs, liver, and kidneys. Additionally, Fusarium may cause gastrointestinal illnesses, and even illness which affect the female reproductive system. Chronic cases of Cladosporium may produce pulmonary edema and emphysema.

Aspergillus

The least serious of the toxic mold groups, the Aspergillus mold family consists of over 160 species. Only 16 of those cause illness in humans, none of which are fatal if treated.

Toxic molds produce chemicals during their natural growth that are classified as toxins or poisons. The types that have been found to have profound effects on human health, are given the label of "toxic mold."

Toxic molds are all very dangerous if allowed to grow inside the home. Proper precautions should be taken to prevent and eliminate their growth. These measures should include eliminating every material that nourishes the molds, such as old remodeling materials left in a basement. Also, never try to determine the type of mold in your home. Contact a professional to test any mold colony you may find, and consult with your family physician.

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.

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

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

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

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

If you have additional questions, please contact us.

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.

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:

http://estore.aprilaire.com/catalog/air-cleaners/model-2120-parts

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.

  • 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 1700 Dehumidifier, new drain line?

Monday, March 26, 2012 by Aprilaire Team
Consumer question:
 
Our drain line is leaking and a replacement line is to be installed. I have purchased a braided vinyl hose thinking it would be more durable in an attic. Internal diameter of hose is 1/2 inch, and out diameter is 3/4 inch. Will this fit the Aprilaire 1700? Thank you for the information.

Aprilaires' respone:

Thank you for your question regarding the Aprilaire model 1700 dehumidifier.

You dehumidifier should have a fitting attache to the end of the PVC drain pipe to allow for connecting your 1/2 inch braided drain hose. We recommend that a consistent downward slope to the drain be ensured to prevent water from remaining in the hose, once the unit has shut off. The drain hose should be inspected for cracking every year to prevent leaks and associated water damage.

Thank you for choosing Aprilaire in your home comfort system.

 

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.

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.
