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.
2.
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.
3,
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.

I
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 I A 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 unit first 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 circulation and 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 initial start 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 room temperature 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 in EXHAUST 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
of operation. 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 of front
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 is cooling.
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 insulation in walls and ceilings.
• Closing all heating and ventilation diffusers or vents
(including furnace cold air retum vent) in area being
cooled.
• Closing drapes or blinds on windows that receive
direct sunlight. Installwindow coverings or awnings
on windows not currently covered.
• Adequately ventilating attic. Heat build-up in attic adds
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 is cooling.
Operating Instructions
Normal Operating Sounds
Certain sounds may be made when air conditioner runs,
especialJy in 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.
• Compressorcycles frequently. High efficiency
compressors used in new Kenmora Room
AirConditionersrun more frequently but for shorter
periods and consume less energy than older, less
efficientcompressors.
• Airflowfrom air discharge vent. If sound is distracting,
try adjusting louvers on discharge vent, moving objects
that may be obstructing airflow, or reducing fan speed.
