Normal Sounds

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

	6_o Cools and circulates room air.
	Lowers humidity by removing excess moisture. High moisture levels may
	cause the air conditioner to drip excessmoisture outside.	m
	• Filters out summertime dust, dirt, and some airborne impurities.	m
		8
	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 excessmoisture. 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. This moisture may form ice on the inside coi! if the
	outside temperature is below 65 degrees. Setting the air conditioner on HI, FAN
	ONLYwill defrost the coil.
	Your air conditioner is designed to be easy to operate and to provide plenty of
	cooling power. Your air conditioner is also more efficient than (most) older models
	and may run longer to cool the room, but will use tess energy due to igher energy
	efficiency ratings.
	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. Allow some time to cool the room if the air conditioner
	was recently turned on. Using the "AUTO START" feature will allow you to start
	cooling the room prior to returning home.
	At times using the HI 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 to use.

High Pitched Chatter

Sound of Ru,sbin# Air At the front of the unit, you may hear the sound

of rushing air being moved by the fan.

Sound

As cooling systems cycle on and off, you may hear a "clicking" sound.

Today'shigh efficient compressors may have a high pitched chatter during the cooling cycle.

Unit may vibrate and make

noise because of poor wall or window construction or

incorrect installation.

f_n£im, or Swisbin_ Droplets of water hitting condenser during normal operation may cause "pinging or swishing" sounds.

I_ Troubleshooting Tips t

"Gurgling or hissing"

noise may be heard due to refrigerant passing through evaporation during normal operation.
