smelledor tasted. Many people do not understandwhata humidifier will or will not do.

TYPICAL QUESTIONS
ASKED
1. Why do moisture requirements vary from home to home?
5. Whet else causes static shock besides low humidity?
Requirementsdepend on the amount and drynessof airto be
humidified.The largerand more looselyconstructedthe home,
the greaterthe quantityof moisture required.
Some typesof carpets tend to create more staticthan others.
While the properhumiditylevel will reduce the static level, it
may noteliminatestaticentirely.
2. How can I best check my home's relative humidity?
6. What Is the safe humidity level for my home?
First give your humidifiertime to build up the humidityto an
acceptablelevel. Instrumentsare availableto measure relative
humidity,but from a practical standpoint,your comfortis the
best guide.You cannot depend on table top or wall hung dial
gauges.
In order to determinethe safe relativehumidityfor homes exposedtovariouslow outsidetemperatures,NESCA* conducted
tests and publishedrecommendedhumiditylevelsfor various
outdoortemperatures.These are shown in the chart. These
levels help preventdamage to your home such as water running downthe walls or even buildingup insidethe walls.
The safe indoorrelativehumiditypementageis nota fixednumber but will increaseor decrease as the outdoortemperatures
rise or fall.
3. How long will It take my humidifier to build up the
humidity In my home?
Much dependson the outsidetemperature,timeof year, home
construction,and howdriedout the home hasbecome.In soma
cases, it may take a week or mare.
Outside Temperatures
4. What are some of the common things that cause higher
then average sir leakage In the home, therefore causing
low humidity?
A. Jalousiewindows
B. Open fireplacedampers
C. Cracks aroundwindows end doors
D. Open doors end windows
E. Unusuallylarge attic or foundationvents
F. Range hoodsand bath fans

SPLASH INSIDE HUMIDIFIER:
coating of lime will build up. It could, in extreme cases, cause
leaking of water from the humidifier.
This humidifier depends on the difference of air pressu re between
the supply air plenum and the return air plenum to propel air
through the humidifier. Some furnaces have higher pressures than
others, This could result in air traveling at high speed through the
humidifier. This can cause droplets of water to be picked up and
splashed against the inside of the humidifier case. Eventually a
TO REDUCE SPLASH:
Partially close the damper located in the collar on the return air
plenum. Some experimenting may be necessary to find the proper
setting.

AND SERVICE INSTRUCTIONS:
CAUTION: Before performing service, inspection, or
maintenance:
[] 1
Periodic inspection and preventative maintenance of these components is important for continued, efficient operation of the humidifier. Refer to exploded view for location of components.
Turn off electricity at furnace, humidifier, and humidistat.
2
Turn off water at humidifier saddle valve.

Wear safety glasses.
CAUTION: Be sure water and electricity are turned off
as advised above.
distribution
This humidifier is an appliance that evaporates water in large quantities. The dissolved minerals normally found in tap water in varying degrees are left as lime deposits on the media pad and other
parts in contact with the water. Deposit build-up will reduce humidifier output. Annual cleaning and replacement of the media
pad is recommended. Since water conditions vary, it may be necessary to service more or less often. Establish your own service
schedule. Ease of service has been foremost in the design of this
humidifier following the steps below:
