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.
Unit Vibration
The unit may vibrate and make noise
because of poor wail or window construction.

NORMAL SOUNDS FIG,25
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. The proper size is determined by the number of square feet in the area to be cooled.
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 you do not have the air conditioner set to cool the air This will decrease your cost of use.
Condenser
You may hear droplets of water hitting the condenser, causing a pinging or clicking sound.
