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.
Operation of Current Device

The air conditioner will control room temperature
automatically round the temperature point set by you.
In this mode, the fan speed cannot be adjusted, it starts
automatically at a speed according to the 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

The Closed position is used when maximum cooling
is desired. It may also be used for air recirculation
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.
CARE AND CLEANING
Air Directional Louvers
4-Way Louvers
The 4-Way air directional louvers allow you to
direct air flow up or horizontal, 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.
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 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.
CAUTION
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.

CARE AND CLEANING
Air Filter Cleaning
Take the filter by the center and pull up and out.
Wash the filteru sing l iquid d ishwashing d etergent a nd w arm
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
a i r fil ter. Never attempt to operate the unit without the air
filter.
NOTE:
To prevent rust or electrical connections from being
damaged, store air conditioner in an upright position and in
a dry place.
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.
