Humidifier Operations

Your new Sears humidifier is designed to satisfy home humidity requirements through the principle of evaporation of water in the air.
After water is added to the bottle, the illters begin to soak up the water and become totally saturated in approximately 30 minutes. Air drawn in from the rear of the humidifier passes through the filters by means of a circulation fan. As air  passes through the filters, moisture is absorbed into the air and then released in the form of vapor. No water droplets will enter the home. All evaporation into the air takes place in the humidifier, which means that the residue left by evaporating water is not passed into the home, but remains in the filter.

CAUTION: Use only 42-14900 EPA Registered Bacteriostat available from SEARS Retail store. Under no circumstances should you use water treatment products designed for Roto belt or Ultrasonic humidifiers.

CAUTION: To reduce the risk of injury, fire or damage to humidifier, use only cleaners specifically recom- mended for humidifiers.
Never use flammable, combustible or poiso- nous materials to clean your humidifier. To reduce the risk of scalds and damage to humidifier, never put hot water in humidifier.

Assembly

Your new Sears Kenmore humidifier is  completely assembled for you to use.
Follow the instructions of this owner’s manual for proper usage.

Location Instructions

WARNING: For your own safety, do not use humidifier if any parts are damaged or m ss ng.

Step 1
Place humidifier on a flat level surface in an area of house where most humidity is needed, or one which would likely result in moist air being circulated throughout the house such as near a cold air return. Placing the unit level is very  important if the humidifier is located on carpeting.
Moist air (humidity) produced will disperse into the whole house, but area closest to the unit will have the highest humidity.
If the unit is positioned close to a window, condensation may form on the window pane.
If this is not appropriate the unit should be repositioned in another location.
NOTE: Due to release of cool, moist air from humidifier, it is best to direct air away from home thermostat and hot air registers.
It is best to position humidifier next to an inside wall. Hot air registers and cold air from outside walls can affect the efficiencies of the controls. Unit should not be placed where warm air from a hot air register blows directly on unit.

Step 2
The humidifier should be positioned with the back (cord exit side), at least 2 inches away from the wall. Air needs to enter through the louvers in the rear of the cabinet in order for the humidifier to operate at peak efficiency.

Electrical Hook-Up

Locate nearest 120V A.C. wall socket in the location desired, preferably on inside wall. Plug in the electrical cord.

WARNING: To reduce the risk of fire or shock hazard, humidifier should be plugged into a 120V A.C. outlet.
Do not use extens on cords.

To reduce the risk of electrical shock, this humidifier has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse plug.
If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

Water Fill

WARNING: To reduce the risk of shock, always unplug humidifier before cleaning or servicing.
WARNING: To reduce the risk of fire or shock hazard, do not pour or spill water into control or motor area.
Close the control cover. If controls get wet, let them dry completely and have unit checked by an authorized service personnel before plugging in.

This humidifier is designed for use with the water bottle located under the bottle cover to the left of the fan assembly. The humidifier should be positioned where it will be operating.
To fill the whole house humidifier, close the control cover and remove the bottle cover. To remove the water bottle, lift the bottle straight up and out of the cabinet.
The water bottle is designed with an “E-ZFill Side-Cap”. Remove the “E-Z-Fill SideCap” on the side of the water bottle by twisting counterclockwise.
Place the opening of the water bottle under a water faucet (the bottle should fit under a four-inch clearance faucet).
Fill with recommended mixture of cold water and if necessary Sears Bacteriostat #4214900 only. Solid debris could make the valve leak.
Install the “E-Z-Fill Side-Cap” by twisting clockwise. Hand tighten only.
Check for possible leaks by performing the following:

1. Grasp bottle handle and hold the bottle upright over a sink.
2. Press up on valve cap plunger for about one second to let out a little water.
3. Release the plunger.
4. Listen for air bubbles. Look for leaks around the “E-Z-Fill Side-Cap”.
5. if you hear air bubbles or see leaks, retighten the “E-Z-Fill Side-Cap” and repeat steps 1-4.

Wipe off excess water from the bottle.

Position the water bottle back into the cabinet by grasping the water bottle handle and lower into the cabinet. The “E-ZFill Side-Cap” must be facing the center of the cabinet. When positioned properly, the plunger will open and water will  flow into the cabinet. The water level will automatically remain at approximately 1″ until the bottle is empty. The unit is now ready for operation.

Operating Humidifier Controls

The operating controls of your Kenmore Quiet Comfort whole house humidifier are located on the top right of the humidifier.
The controls are found under the smoked control cover.
Lift the control cover by placing your finger in the round cutout and lifting. The cover will stay open. Now you can clearly see the control area. Familiarize yourself with the controls and reference the diagram of the control area for the  correct naming used in this manual.

To Operate the Controls
Humidity Control:
Adjust the amount of humidity depending on your needs. The humidifier will turn on and off as required to maintain level of humidity selected. A medium setting (half way between MIN and MAX) is recommended, but there are times when low or high amount of humidity may be preferred.
For constant operation of humidifier, MAX allows for the maximum amount of humidity to be evaporated into the air continuously.
IMPORTANT: Water damage may result if condensation starts to form on windows or walls. Humidity Control setting should be lowered until condensation no longer forms.

Speed Control
Your Kenmore Quiet Comfort Whole House humidifier has a three speed fan control switch. (1-Low, 2-Medium and 3High).
The maximum humidity output is obtained with the fan control on high (3).
The higher the air flow speed, the more water is evaporated and released into the air. Low speed (1) is the quietest and is provided for conditions that may not require as high an evaporation rate.

Fill Light
When the unit has a small amount of water left in it, the fill light will come on and the unit will automatically shut off.

Using Your Humidifier

Step 1
Be sure unit is full of water and plugged in.
Step 2
Set the Speed Control to LOW (1).
Step 3
Set Humidity Control to a medium position (half way between MIN and MAX.)
NOTE: Humidifier should operate with humidity control on the recommended medium setting.
If it does not, the humidity is at a relatively high level. To test the unit under this condition, turn Humidity Control all the way to MAX and unit should begin to operate. After the unit has been tested, set Humidity Control to medium or  desired level.
Allow 24 hours for humidifier to adjust.
If humidity level in home is sufficient, the humidifier will only operate with Humidity Control set on maximum.
IMPORTANT: Water damage may result if condensation starts to form on windows or walls. Humidity Control setting should be lowered until condensation no longer forms.
Step 4
If humidifier stops running and the Fill Light is not illuminated, the humidity level is at the normal requirements for that setting or it is adjusting to the home conditions.
The table below shows recommended indoor humidity levels. The figure below shows approximate relative humidity percentages which correspond to the various settings of the Humidity Control.
