somedegreeofcoolingwillcontinue.
TO SELECT THE
OPERATING MODE:
Press the Mode
button.
DO THIS:
To choose operating mode, press the Mode
button. Each time you press the button, a mode
is selected in a sequence that goes from Auto,
Cool, Dry and Fan. The indicator light beside
will be illuminated and remained on once the
mode is selected.
NOTE:
To operate on Auto feature:
In this mode, the fan speed cannot be adjusted,
it starts automatically at a speed according to
the room temperature. If the room does not get
too warm, it will stay at Low speed.
To operate on Fan Only:
Use this function only when cooling is not
desired, such as for room air circulation or to
exhaust stale air(on some models).
(Remember to open the vent during this function,
but keep it closed during cooling for maximum
cooling efficiency.) You can choose any fan
speed you prefer.
During this function, the display will show the
actual room temperature, not the set temper-
ature as in the cooling mode.
TO USE THE ENERGY
SAVER FEATURE:
Press the button
DO THIS:
In this mode, the fan will continue to run for
3 minutes after the compressor shuts off. The
fan then cycles on for 2 minutes at 10 minute
intervals until the room temperature is above
the set temperature, at which time the
compressor turns back on and cooling stars.
NOTE:
SLEEP FEATURE:
Press Sleep
button
DO THIS:
In this mode the selected temperature will
increase by 2 degrees F 30 minutes after the
mode is selected. The temperature will then
increase by another 2 degrees F after an
additional 30 minutes. This new temperature
will be maintained for 7 hours before it returns
to the originally selected temperature. This
ends the Sleep mode and the unit will continue
to operate as originally programmed. The
Sleep mode program can be cancelled at any
time during operation by again pressing the
Sleep button.

To operate on Dry mode:
In this mode, the air conditioner will generally
operate in the form of a dehumidifier. Since
the conditioned space is a closed or sealed
area, some degree of cooling will continue.
TO SELECT THE
OPERATING MODE:
Press the Mode
button.
DO THIS:
To choose operating mode, press the Mode
button. Each time you press the button, a mode
is selected in a sequence that goes from Auto,
Cool, Dry and Fan. The indicator light beside
will be illuminated and remained on once the
mode is selected.
NOTE:
To operate on Auto feature:
In this mode, the fan speed cannot be adjusted,
it starts automatically at a speed according to
the room temperature. If the room does not get
too warm, it will stay at Low speed.
To operate on Fan Only:
Use this function only when cooling is not
desired, such as for room air circulation or to
exhaust stale air(on some models).
(Remember to open the vent during this function,
but keep it closed during cooling for maximum
cooling efficiency.) You can choose any fan
speed you prefer.
During this function, the display will show the
actual room temperature, not the set temper-
ature as in the cooling mode.
TO USE THE ENERGY
SAVER FEATURE:
Press the button
DO THIS:
In this mode, the fan will continue to run for
3 minutes after the compressor shuts off. The
fan then cycles on for 2 minutes at 10 minute
intervals until the room temperature is above
the set temperature, at which time the
compressor turns back on and cooling stars.
NOTE:
SLEEP FEATURE:
Press Sleep
button
DO THIS:
In this mode the selected temperature will
increase by 2 degrees F 30 minutes after the
mode is selected. The temperature will then
increase by another 2 degrees F after an
additional 30 minutes. This new temperature
will be maintained for 7 hours before it returns
to the originally selected temperature. This
ends the Sleep mode and the unit will continue
to operate as originally programmed. The
Sleep mode program can be cancelled at any
time during operation by again pressing the
Sleep button.

AIR CONDITIONER FEATURES (CONTINUED)
Additional things you should know
Now that you have mastered the operating procedure, here are more features in your control that
you should become familiar with.
The Cool circuit has an automatic 3 minute time delayed start if the unit is turned off and on
quickly. This prevents overheating of the compressor and possible circuit breaker tripping.
The fan will continue to run during this time.
The control will maintain any set temperature within 2 F, between 60 F and 90 F degrees.
The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius.
To convert from one to the other, press and hold the UP and DOWN Temp/Timer buttons at the
same time, for 3 seconds.
Exhaust Control
This Exhaust Control allows the air conditioner to either circulate inside air (Closed) or exhaust
air to the outside (Open).
The Closed position is used when maximum cooling is desired. It may also be used for air re-
circulation without cooling when the air conditioner is set in any FAN position.
The Open position removes stale air from the room and exhausts it to the outside. Fresh air is
drawn in through normal passages in the home.
4-Way Louvers
The 4-Way air directional louvers allow you to
direct air flow up or down, left or right throughout
the room as needed. To adjust the air directional
louvers side-to-side, use the center handle as
you move it side-to-side.

Press the Clean Air button, the ion generator is
ener gized and will help to remove pollen and
impurities from the air, and trap them in the filter.
