SAFETY

IMPORTANT SAFETY INSTRUCTIONS

The safety instructions below will tell you how to use your room air conditioner to avoid harm to yourself or damage to your ROOM AIR CONDITIONER.

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.

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.

•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, you may want to 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 installation instructions for possible future use in removing or reinstalling this unit.

•Use gloves when handling the air conditioner. Be careful to avoid cuts from sharp metal fins on front and rear coils.

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 plugged into 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 run air conditioner with a protective covering. This could result in mechanical damage within the air conditioner.

•Do not use an extension cord or an adapter plug.

Avoid fire hazard or electric shock. Do not use an extension cord or an adapter plug. Do not remove any prong from the power cord.

ENERGY SAVING IDEAS

•The capacity of the room air conditioner must fit the room size for efficient and satisfactory operation.

•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.

•Do not block air conditioner flow inside with blinds, curtains, or furniture, or outside with shrubs, enclosures, or other buildings.

•Close the floor and wall registers and the fireplace damper so cool air does not escape up the chimney or 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 MAINTENANCE section of this manual.

•Proper insulation and weather 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 conditioner's work load.

•Operate heat producing appliances such as ranges, washers, dryers, and dishwashers during the coolest part of the day.

INSTALLATION

INSTALLATION

Pick a location which will allow you to blow the cold air into the area you want. Windows used for installation must be strong enough to support the weight of the air conditioner. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.

When cooling more than one room, installation location is very important. To cool your rooms, cold air must be blown from the air conditioner in a straight path.

HOW TO INSTALL

If the air conditioner is blocked by a storm window frame, see step 19 on page 8 before beginning to install.

OPERATION

HOW AND WHY

Your room air conditioner provides the following functions to make hot weather living more comfortable:

•Cools and circulates room air.

•Lowers humidity by removing excess moisture.

•Filters out summertime dust, dirt, and some airborne impurities.

The air conditioner performs these functions by drawing room air through a filter which traps dust and dirt particles. The air then passes over a cooling coil which refrigerates the air and removes excess moisture. The same air is then returned to the room– cooler, drier, and cleaner. Moisture removed from the room air is carried to the outside and evaporated.

Your air conditioner is designed to be easy to operate and to provide plenty of cooling power.

NORMAL SOUNDS FIG. 23

Aside from the regular fan motor and compressor sounds coming from your air conditioner, you will once in a while hear a pinging sound. This is the result of moisture being picked up from the air in the room and thrown against the air conditioner's fan. This is normal and should not be cause for concern. Also, do not be alarmed if you hear a slight hissing or gurgling sound coming from your air conditioner after it is off. These are normal coolant noises.

CAPACITY AND RUNNING TIME

Proper unit size is important in deciding the desired comfort for the area you want to cool. An undersized unit will not have the capability to cool, leaving the area uncomfortably warm. The proper size is determined by the number of square feet in the area to be cooled, indoor and outdoor temperature and humidity.

Whenever the heat or humidity load is above normal the air conditioner must run longer and more often to keep the desired temperature you have selected, Under heavy heat load conditions the air conditioner may need to run constantly to keep the temperature you want.

At times using the MED FAN setting to circulate the room air may make it comfortable even though the air is not being cooled. This will decrease your cost of use.

Compressor

The modern high efficiency compressor may have a high pitched hum or pulsating noise that cycles on and off.

Unit Vibration		Fan

or window construction.

Condenser

You may hear droplets of water hitting the condenser causing a pinging or clicking sound.

						OPERATION
FEATURES								USING THE AIR CONDITIONER
								To reduce the risk of fire, electric

								To begin operating the air conditioner after
								installation, follow these steps:
								1. Plug in the air conditioner. (To prevent electrical
								hazards, do not use an extension cord or an
								adapter plug.)
								2. Set the exhaust vent to the CLOSE position.
								3. Set the TEMP Control to the coolest setting.
								4. Set the MODE control at the highest COOL level.
								5. Adjust the louvers for comfortable air flow.

								NOTE : If the air conditioner is turned off, wait 3
								minutes before restarting. This allows pressure
								inside the compressor to equalize. Failure to wait 3
								minutes before restarting may cause inefficient
								operation.
								If you move the TEMP Control to a warmer, then
