NOTE
The power supply cord with this
air conditioner contains a current
detection device designed to reduce
the risk of fire.
Please refer to the section Operation of
Current Device for details.
In the event that the power supply cord
is damaged, it can not be repaired. It
must be replaced with a cord fromthe
manufacturer.
WARNING - For your safety
• Do not store or use gasoline or other
flammable vapors and liquids in the
vicinity of this or any other appliance.
• Avoid fire hazard or electric shock.
Do not use an extension cord or an
adaptor plug. Do not remove any
prongs fromthe power cord.
WARNING - Electrical Information
The complete electrical rating of
your new roomair conditioner is
stated on the serial plate. Refer to the
rating when checking the electrical
requirements.
• Be sure the air conditioner is
properly grounded. To minimize
shock and fire hazards, proper
grounding is important. The power
cord is equipped with a three-prong
grounding plug for protection against
shock hazards.
• Your air conditioner must be
connected to a properly grounded
wall receptacle. If the wall receptacle
you intend to use is not adequately
grounded or protected by a time
delay fuse or circuit breaker, have a
qualified electrician install the proper
receptacle.
• Ensure the receptacle is accessible
after the unit installation.
• Do not run air conditioner without
outside protective cover in place.
This could result in mechanical
damage within the air conditioner.

• Do not use this device to turn the unit on or off.
• Always make sure the RESET button is pushed in for correct operation.
• The power supply must be replaced if it fails to reset when either the TEST button
is pushed, or it can not be reset. Please contact Customer Service.
• If power supply cord is damaged, it can not be repaired. It MUST be replaced with
a new cord. Please contact Customer Service.
WARNING - Prevent Accidents
To reduce the risk of fire, electrical shock, or injury to persons when using your air
conditioner, follow basic precautions, including the following:
• Be sure the electrical service is adequate for the model you have chosen. This
information can be found on the serial plate, which is located on the side of the
cabinet and behind the grille.
• If the air conditioner is to be installed in a window, you will probably want to clean
both sides of the glass first. If the window is a triple-track type with a screen panel
included, remove the screen completely before installation.
• Be sure the air conditioner has been securely and correctly installed according to
the installation instructions in this manual. Save this manual for possible future use
in removing or installing this unit.
• When handling the air conditioner, be careful to avoid cuts fromsharp metal fins
on front and rear coils.

Air Conditioner Operation
WARNING
To reduce the risk of fire, electrical shock, personal injury or property, read the
SAFETY PRECAUTIONS before operating this appliance.
NOTE
The cooling mode has an automatic 3 minutes time delayed start if the unit is turned
off and on quickly. This prevents overheating of the compressor and possible tripping.
Operating
Instructions
TO BEGIN OPERATING THE AIR CONDITIONER, FOLLOW THESE STEPS:
1. Set the lowest number (coldest setting).
2. Set the selector control to the highest COOL setting.
3. Adjust the louver for comfortable air flow (see Air Directional Louvers).
4. Once the room feels colder, adjust the setting you find most comfortable.
5. Make sure that the air flow inside and outside are not obstructed by anything.
6. This air conditioner is designed to be operated under the following conditions:
Cooling Operation
Outdoor temp.: 64-109°F/18-43°C (64-125°F/18-52°C
for special tropical models)
Indoor temp.: 62-90°F/17-32°C
Heating Operation Outdoor temp.: 23-76°F/-5-24°C

SLEEP FEATURE:
Press Sleep Sleep button to initiate the
sleep mode. In this mode the selected
temperature will increase by 2°F/1
(or 2)°C 30 minutes after the mode
is selected. The temperature will then
increase by another 2°F/1 (or 2)°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 pressing the
Sleep button again.
CHECK FILTER FEATURE:
Press Filter Check filter button to initiate
this feature. This feature is a reminder
to clean the Air Filter for more efficient
operation. The 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.
ENERGY SAVER FEATURE:
Press Energy
Saver Energy Saver button to
initiate this function. This function is
available on COOL, DRY, AUTO (only
AUTO-COOLING and AUTO-FAN) modes.
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 resumes.
TO SELECT THE OPERATING MODE:
To choose operating mode, press Mode
Mode button. Each time you press the
button the unit cycles through the modes,
Auto, Cool, Dry, and Fan. The adjacent

Auto-Cooling and Auto-Fan) modes.
To operate on Auto feature:
• When you set the air conditioner to
AUTO mode, it will automatically select
cooling or fan only operation depending
on what temperature you have selected
and the current room temperature.
• The air conditioner will control room
temperature automatically according
to the temperature you’ve set.
• In this mode, the fan speed cannot be
adjusted, as it’s automatically controlled
according to the temperature setting
and room temperature.
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 temperature as in the
cooling mode.
• In Fan Only mode, the temperature is
not adjusted.
To operate on Dry mode:
In this mode, the air conditioner will
generally function as a dehumidifier. Since
the conditioned space is a closed or sealed
area, some degree of cooling will occur.

Instructions
1. Place unit on floor, a bench or a table. There is a left and right side accordion panel; be
sure to use the proper panel for each side. When installed, the flange for securing the
panel in place to the window sill will be facing into the room.
A. Hold the side panel in one hand and gently pull back the center to free the open
end. See Fig. 1.
B. Slide the free and “I” section of the panel directly into the cabinet as shown in Fig. 2.
Slide the panel down. Be sure to leave enough space to slip the top and bottom of
the frame into the rails on the cabinet.
C. Once the panel has been installed on the side of the cabinet, make sure it sits
securely inside the frame channel by making slight adjustments. Slide the top and
bottom ends of the frame into the top and bottom rails of the cabinet. Fig. 3.
NOTE
Top rail and side panels at each side are offset to provide the proper pitch to the rear of
5/16” (8mm). This is necessary for proper condensed water management and drainage. If
you are not using the side panels for any reason, this pitch to the rear must be maintained.
NOTE
For safety reasons, all
four (4) screws MUST be
securely fastened.
C: Align the hole in the top rail with those in the top of the unit as shown in Fig. F.
D: Secure the top rail to the unit with the 3/8” (9.5mm) screws as shown in Fig. G.

Check that air conditioner is tilted back
per dimension H (Fig. 5) (tilted about 3°
to 4° downward to the outside). After
proper installation, condensate should
not drain fromthe overflow drain hole
during normal use. Adjust the slope if
otherwise.

Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the
unit before cleaning to prevent shock or fire hazards.

operate the unit without the air filter.

window according to the installation instructions. Cover it with plastic or return it to
theoriginal carton.

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.
• Push the vent handle to the closed position (where applicable). Open the front panel.
• Take the filter by the center and pull up and out.
• Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.
• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.
• You may also vacuum the filter clean rather than washing.
