IMPORTANT SAFETY INSTRUCTIONS
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 cannot be
repaired-it must be replaced with a
cord from the Product Manufacturer.
Power supply cord
with 3-prong grounding plug
and current detection device
,
Do not, under any
circumstances, cut,
remove, or bypass
the grounding prong.
,
WARNING
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 prong from the power cord.
WARNING
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.
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 used in 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 side protective cover in place.
This could result in mechanical damage within the air conditioner.
Do not use an extension cord or an adapter plug.
For your safety
Electrical Information

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

and remained on once the mode is selected.
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 temperature as in the
cooling mode.
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.
NOTE:
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.

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 Left and Right Temp/Timer buttons at the
same time, for 3 seconds.
NOTE:
This feature can be activated from the remote
control ONLY. The remote control serves as a
remote thermostat allowing for the precise
temperature control at its location.
To activate the Follow Me feature, point the remote
control towards the unit and press the Follow Me
button. T
he remote display is actual temperature
at its location. The remote control will send this
signal to the air conditioner every 3 minutes interval
until press the Follow Me button again.
If the unit
does not receive the Follow Me signal during any 7
minute interval, the unit will beep to indicate the
Follow Me mode has ended.
The actual temperature can be displayed at the unit
by pressing the Fan Only mode. When in the Cool
mode, the unit display indicates the set temperature.
Fresh Air Vent Control(on some models):
The Fresh Air Vent allows the air conditioner to:
1. Recirculate inside air - Vent Closed (See Fig.1)
2. Draw fresh air into the room- Vent Open (see Fig.2)
3. Exchange air from the room and draws fresh air into
the room - Vent and Exhaust Open (see Fig.3)
Figure 1 (VENT CLOSED)
Figure 2 (VENT OPEN)
Figure 3 (VENT & EXHAUST OPEN)

Air Directional Louvers
The louvers will allow you to direct the air flow Up
or Down(on some models) and Left or Right
throughout the room as needed. Pivot horizontal
louvers until the desired Up/Down direction is
obtained.
Center Handles
Move the Center Handles from side to side until the
Air Direction
desired Left/Right direction is obtained.
INSTALLATION INSTRUCTIONS
Your air conditioner is designed to install in standard double hung windows with opening widths of
23 to 36 inches(584mm to 914mm) (See Fig.1).

CARE AND CLEANING
CAUTIONCAUTION
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit
before cleaning to prevent chock or fire hazards.
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.
Push the vent handle to the Vent Closed position
(where applicable).
Open the front panel.
Grasp the filter by the center and pull up and
out.
Wash the filter using liquid dishwashing deter gent and warm water. Rinse filter thoroughly.
Gently shake excess water from the filter. Be
sure the filter is thoroughly dry before replacing.
Or, instead of washing you may vacuum the
filter clean.
Note: Never use hot water over 40 C(104 F) to
cl ean th e ai r fil ter. Never attempt to operate the
unit without the air filter.
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 liquid 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.
Plug in air conditioner.
Winter Storage
If you plan to store the air conditioner during the winter,
remove it carefully from the window according to the
installation instructions. Cover it with plastic or return it
to the original carton.
