THANK YOU!
Thank you for selecting a Sears Humidifier. It wiii provide years of service if you give it a little care.
Humidity can be puzzling. It cannot be seen, heard,
touched, smelled or tasted. Many people do not understand what a humidifier wiii or wiii not do.
Probably the best way to judge whether the humidity is too high, too low, or about right is to watch your windows. If they are heavily fogged you most likely have too much. If there is no moisture on them at aii, especially in the corners, you have too little.
NOTE: Moisture wiii not normally form on thermopane or when storm windows are used. If there is some
moisture in the window corners and along the edges, the humidity is just about right. This is a good rule of thumb, if you do not have an expensive piece of test- ing equipment. Your comfort is another good check.
TYPmCAL QUESTmONS ASKED
1.Why do moisture requirements vary from home to home?
Requirements depend on the amount and dryness of air to be humidified. The larger and more loosely constructed the home, the greater the quantity of moisture required.
2.How can I best check my home's remative
First give your humidifier time to build up the humidity to an acceptable level. Instruments are available to measure relative humidity, but from a practical standpoint, your comfort is the best guide. You cannot depend on table top or wall hung dial gauges
3.How mongwimmit take my humidifier to buimd up the humidity in my home?
Much depends on the outside temperature, time of year, home construction, and how dried out the home has become. In some cases, it may take a week or more.
4.What are some of the common things that cause higher than average air meakage in the home, therefore causing mow humidity?
A. Jalousie windows
B.Open fireplace dampers
C.Cracks around windows and doors
D.Open doors and windows
E.Unusually large attic or foundation vents
RRange hoods and bath fans
5.What erasecauses static shock besides mow
Some types of carpets tend to create more static than others. While the proper humidity level wiii reduce the static level, it may not eliminate static entirely.
6_ What is the safe humidity level for my home?
In order to determine the safe relative humidity for homes exposed to various low outside tempera- tures, NESCA* conducted tests and published recommended humidity levels for various outdoor temperatures. These are shown in the chart below. These levels help prevent damage to your home such as water running down the wails or even building up inside the wails.
The safe indoor relative humidity percentage is not a fixed number but wiil increase or decrease as the
outdoor temperatures rise or fail.
F | 20% | |
0 o | F | 25% |
10 ° | F | 3O% |
20 ° | F | 35% |
30 ° | F | 35% |

7_ Can I install this Sears Humidifier with a heat
pump?
Yes, you can! This is a normal installation using this Sears Furnace Mount Humidifier. No special accessory is required. The diagram below shows the functioning of the unit and also its placement on the plenum. Installed with a heat pump, it will evaporate 11 gallons, for a well insulated house up to 2400 sq. ft.
To install with a heat pump, the humidifier should be mounted on a warm air plenum (A) or duct (B) of a heat pump system. Some of the warm air is
drawn from the duct, forced through the wetted media and returned to the same duct. A
tained blower moves the air from the duct through the humidifier and back into the same duct. The
heat pump air delivery across the coil is not dis- turbed, or altered, in any way. The heat pump, there- fore, continues to operate at maximum efficiency.
