Important Safety  
Instructions  
For Your Safety  
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of  
this or any other appliance. Read product labels for flammability and other warnings.  
• Be sure to unplug the unit before cleaning or performing other  
maintenance to prevent electric shock or fire which could cause serious  
injury or death.  
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 either on the side  
of the cabinet or 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 separate installation instructions provided with this manual. Save this manual  
and the installation instructions for possible future use in removing or reinstalling  
this unit.  
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.  
• When handling the air conditioner, be careful to avoid cuts from sharp metal fins  
on front and rear coils.  
Grounding type  
wall receptacle  
Electrical Information  
The complete electrical rating of your new room air 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 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.  
Do not, under  
any circumstances,  
cut, remove,  
or bypass the  
grounding prong.  
• Do not run air conditioner with outside protective cover in place. This could result  
in mechanical damage within the air conditioner.  
• Do not use an extension cord or an adapter plug.  
• Do not block air flow inside with blinds, curtains or furniture; or  
outside with shrubs, enclosures, or other buildings.  
• The capacity of the room air conditioner must fit the room size for efficient and  
satisfactory operation.  
Energy Saving Ideas  
• Install the room air conditioner on the shady side of your home. A window that  
faces north is best because it is shaded most of the day.  
• Close the fireplace damper, floor and wall registers so cool air does not escape  
up the chimney and into the duct work.  
• Keep blinds and drapes in other windows closed during the sunniest part of the  
day.  
• Clean the air filter as recommended in the section “Care and Cleaning.”  
• Proper insulation and water stripping in your home will help keep warm air out  
and cool air in.  
• External house shading with trees, plants or awnings will help reduce the air  
conditioners work load.  
• Operate heat producing appliances such as ranges, washers, dryers and  
dishwashers during the coolest part of the day.

To reduce the risk of fire, electric shock, or injury to persons, read  
the IMPORTANT SAFETY INSTRUCTIONS before operating this appliance.  
Using Air Conditioner  
To begin operating the air conditioner, follow these steps:  
1. Plug in the air conditioner. (To prevent electrical hazards, do not use an extension  
cord or an adapter plug.)  
NOTE: If the air conditioner is turned off,  
wait 3 minutes before restarting. This  
allows pressure inside the compressor to  
equalize. Failure to follow these  
instructions may cause inefficient  
operation.  
2. Set the thermostat to the highest number (coldest or cooler setting).  
3. Set the selector control to the highest FAN or COOL setting (see below).  
4. Adjust the louvers for comfortable air flow (see Air Directional Louvers).  
5. Once the room has cooled, adjust the thermostat to the setting you find most  
comfortable.  
Review the “Air Conditioner Features” section for other settings.  
The controls featured in this manual are representational of the many models  
available. Your model may offer slightly different features.  
Air Conditioner Features  
Selector Control  
The selector control turns the unit on or off and allows a choice of either cooling  
room air, circulating room air at the existing temperature, or heating room air.  
COOL/FAN  
Operate COOL/FAN modes according to the following suggestions:  
• ON/OFF or OFF = Turns air conditioner on and off.  
• HIGH COOL = Maximum cooling speed. Begin operation of the air conditioner in  
this mode.  
• LOW COOL = Fan runs slow for quiet operation when maximum cooling is not  
needed.  
• HIGH FAN = Maximum air circulation without cooling.  
• LOW FAN = Slow air circulation without cooling.  
HEAT  
The HEAT selection provides quiet, efficient circulation of warm air. Turn the selector  
to the HEAT setting and set the thermostat at WARMER setting. When the HEAT  
setting is selected, the thermostat maintains the temperature by automatically  
turning the heater on and off in response to room temperature. The fan runs  
continuously to circulate air in the room.  
Once the room is warm, adjust the thermostat to a less warm position. This provides  
less heat, or cooler temperatures.  
A slight heat odor may come from the unit when first switching to HEAT after the  
cooling season is over. This odor, caused by fine dust particles on the heater, will  
disappear quickly.  
Automatic Thermostat  
When a COOL or HEAT setting is selected, the thermostat controls the amount of  
cooling or heating by automatically turning the cooling compressor or heater on  
and off in response to the room temperature.  
5
 
Automatic Thermostat (continued)  
Air Conditioner Features  
(continued)  
Set the thermostat at the COOLER setting for cooling, and the warmer setting in  
the HEAT mode. Once the room has reached the desired temperature, adjust the  
thermostat to a setting providing the most comfortable amount of cooling or  
heating. COOLER provides lower room temperatures. WARMER provides higher  
room temperatures.  
Night Time Cooling  
When outside temperatures drop below 70°F (21°C) and the unit is cooling, frost  
may form on the coils and block airflow into the room. If this occurs, operate the  
air conditioner on the FAN setting to defrost the coil.  
If cooling while the outside temperature is low, set the thermostat to the middle  
position. Make sure the louvers are open. This will help prevent frost build-up.  
Air Directional Louvers  
Air directional louvers control air flow direction.  
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.  
6
 
Clean your air conditioner occasionally to keep it looking new.  
Be sure to unplug the unit before cleaning to prevent  
electric shock or fire hazards.  
Care and 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.  
• Tilt the Horizontal Louvers in the UP position, before pulling the filter out.  
• Grasp 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 filter is thoroughly  
dry before replacing.  
• Or, instead of washing you may vacuum the filter clean.  
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.  
• The cabinet front can be removed for more thorough cleaning. Refer to “Front  
Removal” in this manual.  
• Clean the front in a sink using liquid dishwashing detergent and warm water. Rinse  
thoroughly and dry.  
• Replace cabinet front. Replace the screws.  
• Replace front panel (if applicable) and filter. Plug in air conditioner.  
Front Removal  
To remove the front for more thorough cleaning follow these steps:  
• Unplug power cord from the wall outlet.  
• Remove knobs by firmly pulling (these knobs are interchangeable).  
• Remove the filter to expose the two (2) screws holding the front in place.  
• Remove the two (2) screws and save for replacing.  
• Press firmly on each side of the cabinet close to the front, approximately half way  
down.  
• While pressing on the sides of the cabinet, gently pull the front out and lift up to  
release it from the cabinet.  
• Clean as instructed in Care and Cleaning. Reinstall the front when dry by reversing the  
above instructions.
