To Select Operating Mode:
To choose the operating mode press Mode . Each time you press this button a mode is
selected in a sequence that goes from Auto, Cool, Dry, Heat, to Fan. The indicator light
beside the mode button will be illuminated and remain on once the mode is selected.
To Operate in Auto Mode:
AUTO Mode is a setting that allows the unit to automatically switch between COOL, FAN, and
HEAT in order to achieve and maintain the desired set temperature.
•When set to “Auto” mode, the unit will automatically select cooling, heating, or fan only
operation depending on the temperature selected and the current room temperature.
•Once the temperature you selected is achieved the unit will automatically maintain the
room temperature by switching between modes as needed.
•While in AUTO Mode, the fan speed cannot be adjusted manually.
•When operating in AUTO MODE, the control panel display will NOT illuminate to indicate
any change between Cool/Fan/Heat. The AUTO indicator will remain illuminated.
To Operate in Fan Only Mode:
•Use this function only when cooling is not desired, such as for room circulation or to
exhaust air (remember to open the vent). You can choose any speed you prefer.
•During this function the display will show the actual room temperature as in the cooling
mode.
•In Fan Only mode, the temperature is not adjusted.
To Operate in Dry Mode:
In this mode, the air conditioner will operate as a dehumidifier. Because the conditioned
space is closed or sealed, some degree of cooling will continue to occur.
To Use the Energy Saver Feature:
To start the Energy Saver, press . This feature is available on “Cool”, “Dry”, and “Auto”.
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 point the compressor turns back on and cooling starts.
Note: Heat function is intended to provide supplemental heating in addition to an existing heat
source. The heat function has a lower BTU rating than the cool mode and therefore does not treat
the same square footage. The maximum heating capacity of the unit is 15°F above the ambient
room temperature.
Note: The unit’s temperature sensor is located on the front of the unit near the air intake port. As such, a
temperature reading taken manually on the opposite side of the room may read differently than what the
unit is detecting. Please make note of this when operating your unit.
Also, the unit does not constantly take temperature readings. The unit will take a temperature reading
periodically while operating in AUTO mode, or immediately upon adjustment of the desired set
temperature. As such, it is important to understand that when operating in AUTO MODE the unit may not
switch between Cooling, Heating, and Fan Mode at the exact moment when a temperature change occurs.

11
To Use the Sleep Feature:
To initiate, press the Sleep button . In this mode the selected temperature will increase
(cooling) or decrease (heating) by 2°F (1°C) 30 minutes after the mode is selected. The
temperature will then increase (cooling) or decrease (heating) by another 2°F (1°C) after an
additional 30 minutes. This new temperature will be maintained for 6 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 Use the Timer (Auto Start/Stop) Feature:
•When the unit is on or off, press the Timer button and the “Timer On” indicator light
illuminates. It indicates that the Auto Start program is initiated.
•To switch to off press the Timer button again and the “Timer Off” indicator light
illuminates. It indicates that the Auto Stop program is initiated.
•Press or hold the Up or Down button to change the Auto Time by ½hour
increments up to 10 hours or 1 hour increments up to 24 hours. The control will count
down the time remaining until start.
•The selected time will register in five (5) seconds and the system will automatically
revert back to display the previous temperature setting or room temperature when the
unit is on. (Note-when the unit is off there is no display.)
To Use the Check Filter Feature:
This feature is a reminder to clean the Air Filter for more efficient operation. The LED light will
illuminate after 250 hours of operation. To reset after cleaning the filter press the Check Filter
button and the light will go off.
Digital Display:
Displays the set temperature in “C” or “F” and the Auto-Timer settings. While on Fan only
mode it shows the room temperature.
Error Codes
AS- Room temperature sensor error
- Unplug the unit and plug it back in.
- If the error repeats call for service.
- In Fan only mode it will display “LO” or “HI”.
!- Evaporator temperature sensor error
- Unplug the unit and plug it back in.
- If the error repeats, call for service.
HS-Electric Heating sensor error
- Unplug the unit and plug it back in.
- If the error repeats, call for service.

12
Air Directional Louvers:
The 4-way air directional louvers allow you to direct the air flow Up, Down, Left, and Right
throughout the room as needed. To adjust the air directional louvers side to side use the center
handles as you move side to side.
Additional Tips:
The “Cool” mode has an automatic 3 minute timed delay 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 is capable of displaying the 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.

Maintenance
Clean the air conditioner and filters regularly to maximize performance and efficiency, and
prolong the unit’s life. Be sure to always unplug the air conditioner from the power outlet before
cleaning.
Air Filter Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped
particles in the filter can build up and cause an accumulation of frost on the cooling coils.
1. Push the vent handle to the “vent closed” position.
2. Open the front panel.
3. Grasp the filter, pull up and out.
4. Wash the filter using liquid dishwashing detergent and warm water. Rinse the filter thoroughly.
5. Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing
it.
6. You also have the option of cleaning the filter with a vacuum.
Note: Winter Storage- If you plan to store the air conditioner during the winter, remove it carefully
from the window according to the installation instructions. Make sure to clean the unit thoroughly
and cover it with plastic or return it to the original carton.
Warning: Never use hot water over 40°C (104°F) to clean the air filter. Never attempt to operate
the unit without the air filter.

15
Cabinet Cleaning
•Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front
may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm
water and mild dishwashing detergent. Rinse thoroughly and wipe dry.
•Never use harsh cleaners, wax, or polish on the cabinet front.
•Be sure to wring excess water from the cloth before wiping around the controls. Excess water
in or around the controls may cause damage to the air conditioner.
Normal Sounds
•High Pitched Chatter-High efficiency compressors may have a high pitched chatter during the
cooling cycle.
•Sound of Rushing Air-At the front of the unit, you may hear the sound of rushing air being
moved by the fan.
•Gurgle/Hiss-Gurgling or Hissing noise may be heard due to refrigerant passing through the
evaporator during normal operation.
•Vibration-The unit may vibrate and make noise because of poor wall or window construction or
incorrect installation.
•Pinging or Switching-Droplets of water hitting the condenser during normal operation may
cause these sounds.
Energy Saving Guide
Read and follow the guide below to get the best performance and efficiency from your window air
conditioner:
•Do not cover the air outlet (exhaust) while in use.
