UNDERSTANDING HUMI

THANK YOU! Thank you for selecting a Sears Humidifier. It will

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 will or will 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 all,

especially in the corners, you have too little.

NOTE: Moisture will 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.

TYPICAL QUESTIONS 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 relative humidity?

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 long will it take my humidifier to build 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 leakage in the home, therefore causing low 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 F. Range hoods and bath fans

5. What else causes static shock besides low humidity?

Some types of carpets tend to create more static than others. While the proper humidity level will 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 walls or even building up inside the walls.

The safe indoor relative humidity percentage is not a fixed number but will increase or decrease as the outdoor temperatures rise or fall.

Maximum Sate Recommended

Indoor Relative Humiditv

-10" 0° F 25%

20° 30° F 35%

*NESCA = National Environmental Systems Contractors Association.

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 self-con 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.

SELECTING A LOCATION

Carefully study the location that you choose for your

humidifier. Install the humidifier so that if the humidifier or any connection should leak, the water will not cause damage. Under no condition is Sears, Roebuck and

Co., and the manufacturer, to be held liable for any water damage in connection with this humidifier.

NOTE: Never install humidifier in attic or crawl space where freezing may occur or leaking will cause water damage.

Measure the open area on the furnace supply air

plenum (Fig. 1). You will need a space 20" wide and

13" high. The humidifier will mount on a supply air

plenum isy?" wide by overhanging the sides. In addition, you should have 12" of working area on each side to make the electrical and water connections.

SERVICING

TYPICAL REMOTE INSTALLATION

In some cases it is impossible to install the humidifier directly to the supply air plenum (plenum too small, horizontal attic furnace, etc.). For remote mounting, see Fig. 4. Connect the humidifier to the supply air plenum using the Remote Installation Kit - Sears Stock No. 9372.

REMOTE INSTALLATIONS

Adaptor

NOTE: The easiest and quickest way to service the

humidifier will be from the front. To service from the front you will need 23" of space in front of the plenum and only 2" of space below the humidifier {Fig. 2).

If you do not have 23" of space in front, the humidifier

must be serviced from the bottom. Servicing from the

bottom will require

If you do not have the space needed, or have a counterflow furnace, refer to the installations shown

in Fig. 4, 5 and 6.

NOTE: If you have an air conditioning coil in your supply air plenum, install the humidifier above or to the slope side of the coil.

CAUTION: Be careful not to damage coil when cutting into plenum {Fig. 1).

l^/i clearance {Fig. 3).

HORIZONTAL FURNACE IN ATTIC OR CRAWL SPACE

Always insure that the humidifier is located in the living area (closet or utility room) to easily access for maintenance/servicing and to prevent freezing or water damage (Fig. 5).

The humidifier works well on gravity furnaces because of its self-contained blower system. Use the Remote

Installation Kit, Sears Stock No. 9372. The humidifier

must be at least 6" away from the plenum, due to the

higher operating temperature of the furnace.

NOTE: Furnace temperatures above 250°F may cause failure of fiberglass parts.

Fiber Plenum Ducts

NOTE: The mounting screws supplied are for standard

installation on sheet metal plenum ducts.

If you have fiber plenum ducts, install the plenum stiffener and components with thru-bolts, nuts, and washers (not supplied), if necessary, reinforce the

humidifier mounting area on fiber ducts with sheet

metal and provide additional bracing as required to support the weight of the humidifier and water. (This fiber duct installation hardware is not supplied and

must be purchased from you local hardware store.) You may also consider using the remote mount instal

lation if you have fiber ducts. Purchase the Remote

Installation Kit separately from Sears, Stock No. 9372.

1. The Plenum Stiffener is mounted on the supply air plenum. Mark a level line at least 2" above the top of the furnace on the selected surface, if front service method (Fig. 2) is used. If the humidifier is to be serviced from the bottom (Fig.

3), mark a level line at least iVb' above the top of the furnace. Hold stiffener against the plenum with the bottom edge on a level line and bent edge flanges towards you. Using a pencil, mark the location of all holes except hole “A” on plenum (Fig. 7).

If plenum is narrower than stiffener:

The stiffener can be mounted on a plenum as narrow as 13V2". The stiffener sides will extend past the plenum (Fig 8). Begin installation as follows:

• New mounting holes will have to be drilled. Drill the new holes only as far from the edge as necessary. Use a 1/8" drill bit.

• Mark outline of rectangle as shown in Fig 8.

• Cut out this area of supply air plenum. If edges are rough, file them smooth.

• Proceed to step 6.
