Sizing Instructions

Many complaints about room air conditioners result from units that are over-sized or under-sized for a given

area. Over-sized units cool an area before humidity can

be adequately removed, so air feels cold and clammy. Under-sized units do not sufficiently cool an area.

The following table contains guidelines for properly sizing a room air conditioner for a given area.

To size unit:

1. Determine size (in square feet) of area to be cooled; locate square footage in far left column of table

below.

Required Air Conditioner Cooling Capacity--Btu/hour

Choose right-hand column showing location of room inbuilding:

• Room below attic; insulated ceiling above.

• Room with occupied room above.

• Top floor under insulated roof.

Follow down right-hand column, reading horizontally

from square footage to lind approximate air conditioner capacity (in Btus per hour) required to adequately cool designated area.

NOTE: When determining size of unit, also consider

conditions at bottom of table. For best results, choose air conditioner with cooling capacity

(Btus per hour) closest to, but not exceeding, estimated size.

EXHAUST CLOSEO

See Figure 37. Kenmore room air conditioners have an electronic touch control panel located across top front of

unit. Functions and operation of each control are explained below.

Touch Panel Controls To operate touch controls, press control pad until

indicator above pad lights (does not apply to OFF or

V IA pads).

OFF--Turns air conditioner off. SMART SET--Places air conditioner in "smart" cooling

• mode. SMART SET uses computer logic to cool area

quickly and quietly. When unitfirst turns on, fan starts at high speed. As room temperature nears set

temperature, fan automatically switches to medium speed, then low speed. When room cools to set

temperature, fan continues to run at low speed and compressor cycles on and off to maintain room

temperature. LOW COOL--Fan operates continuously at low speed,

except in power saver mode. If unit is in a cooling mode, compressor cycles on and off as required to maintain set temperature. Select this setting for quietest operation.

MED COOL--Fan operates continuously at medium speed, except in power saver mode. If unit is in a cooling mode, compressor cycles on and off as required to maintain set temperature. Select this setting for

reduced air circulationand quieter operation. HIGH COOL--Fan operates continuously at high speed,

except in power saver mode. If unit is in a cooling mode, compressor cycles on and off as required to maintain set temperature. Use this setting for maximum air circulation and faster cool-down during initialstart up.

POWER SAVER PLUS--Places air conditioner in energy-saving mode. Energy-saving mode works in

conjunction with SMART SET mode and low, medium, or high fan speeds. In energy-saving mode, air conditioner maintains room temperature within 1.5° F of programmed temperature setting. When POWER SAVER PLUS is selected, fan cycles on and off with compressor, instead of running continuously as in other

modes. During compressor off cycle, fan automatically turns on for about 2 minutes at 5 minute intervals to

sample room air temperature. If room temperature is within 1.5°F of programmed temperature, time between sampling increases to a maximum of 15 minutes.

If roomtemperature is more than 1,5°F above programmed setting, fan continues to run and

compressor cycles on to cool room. When room cools to set temperature, compressor and fan turn off and time between air sampling cycles decreases to a

minimum of 5 minutes. FAN ONLY--Fan operates continuously at set speed

(high, medium, or tow) and compressor remains off..

Use this setting to circulate air without cooling and, with

VENT CONTROL inEXHAUST position, to vent room of stale air, odors, smoke, etc. Displays actual room

temperature. V IA --Used to decrease ("down" arrow) or increase

("up"arrow) set temperature. When used with DELAY

START function, arrow keys adjust delay start or stop time.

DELAY START--Allows programming a delay of up to

24 hours before air conditioner starts, or programming air conditioner to automatically stop after up to 24 hours

ofoperation. Automatic start or stop is programmable

from 1 hour (minimum) up to 24 hours (maximum), in

one hour increments. See Operation Instructions for information on programming air conditioner for delay start or automatic stop.

Vent Control Vent control lever, located on lower dght corner offront

panel, controls a damper that recirculates or exhausts room air.

With control in CLOSED position, damper is closed and air in area being cooled is recirculated through air

conditioner,filtered, cooled, and returned to room. No air is exhausted (vented) outside.

NOTE: For maximum efficiency and cooling, vent

control should remain closed any time air

conditioner iscooling.

With control in EXHAUST position, damper is open. When open, room air is exhausted (vented) outside.

Usa exhaust position to remove stale or smoky air. NOTE: To conserve energy, use FAN ONLY position

with EXHAUST feature.

Brightness Adjust Feature (some models) Display brightness can be changed using V I A pad.

To decrease brightness, simultaneously press and hold

OFF pad with"down" arrow.To increase brightness, press and holdOFF pad with =up"arrow key.

Energy Saving Tips In additionto operatingairconditioner in energy-saving

mode, savings of energy and money can be realized by:

• Increasing insulationin walls and ceilings.

• Closing all heating and ventilation diffusers or vents (including furnace cold air retum vent) in area being

cooled.

• Closing drapes or blindson windows that receive direct sunlight. Installwindow coverings or awnings

on windows not currentlycovered.

• Adequately ventilating attic. Heat build-up in atticadds to air conditioner cooling load.

• Avoiding use of heat-producing appliances during hottest parts of day.

• Turning off lightsand appliances when not needed.

• For maximum efficiency and cooling, vent doorshould

be closed whenever air conditioner iscooling.

Operating Instructions

Normal Operating Sounds

Certain sounds may be made when air conditioner runs, especialJyin a cooling mode. Sounds may include:

• Water splashing onto condenser; caused by slinger ring attached to condenser fan. Slinger ring picks up

water (condensate) in base pan and sprays it on condenser to increase efficiency of unit.

Inspecting and Cleaning Base Pan Inspect base pan. Check fordirt, debds, algae build-up in

condensate drain channels, scratches, paint blisters, and

rust spots.

• Vacuum or blow dirt and debris from base pan. Use

brush to loosen difficult accumulations of dirt.

• Ifalgae build-up is present, clean with sponge or cloth

dampened withwarm soapywater.

NOTE: Placing algicide in outdoor side of base pan may

reduce or eliminate problem of algae build-up. For best results,thoroughly clean base pan of

old algae before usingalgicide.

• Use wire brush to remove any rust and loose paint in base pan. Pdme rust spots and bare metal with quality metal pdmer before repainting areas with quality enamel paint.

Outer Case Maintenance

Inspect outer case. Check for scratches, paint blisters,

and rust on both insideand outside of case.

NOTE: Remove chassis from outer case to inspect

case interior.

Repair scratches, rust, and paint blisters using quality enamel paint. Before painting, remove loose paint and rust with wire brush. Prime rust spots and bare metal

with quality metal primer before repainting.

Inspecting and Cleaning Coils Inspect evaporator and condenser coils. Check for bent

fins and accumulations of dirtor other debds that may

reduce or block air flow through coils. Reduced or blocked air flow affects air conditioner efficiencyand can

lead to premature compressor failure.

Attempt to straighten bent fins by "combing" fins with a fine tooth comb. Vacuum (or blow) dirt and debris from

coils. Use brush to loosen difficult accumulations of dirt. NOTE: Especially dirty coils may require professional

cleaning. Contact a local Sears Service Center for professionalcleaning.

Troubleshooting

The following table describes some common problems that may be encountered with a room air conditioner. Each
