How and Why
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.
• Filters out summertime dust, dirt, and some airborne impurities.
m
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
8
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.
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 isabove 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 Fansetting 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.
Normal Sounds
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.
I_ Troubleshooting Tips t
High Pitched Chatter
Today's high 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.
"Gurglingor hissing"
noise may be heard due to refrigerant
passing through evaporationduring normal
operation.
