HOW AND WHY
Your room air conditioner provides the following
functions to make hot weather I]ving more
comfortable:
• Cools and circu{ates room sir,
- Lowers humidity by removing excess moisture.
, Fiite_ out aumtr_rtime dust, dirt, and some
airborne impurities,
The air conditioner performs these fun_ons 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- cooter_ drier, and cleaner. Moisture
removed from the room air is carried to the outside
and evaporated_
Your sir conditioner is designed to be easy to
operate and to provide plenty of cooling power,
NORMAL SOUNDS FtG. ,3
Aside from the regular fan motor and:compn_ssor
sounds coming from your airconditioner, you will
once in s white hear a pinging sound. This is the
result of moisture being picked up from the air in the
room an_ thrown against the air conditioners 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 ofsquare feet
in thearea to be cooled, indoor and outdoor
temperature and hum{dlty.
Whenever the heat or humidity load is above: norms}
the air conditioner must run longer and more olten
to keep the desired temperature you have selected,
Under heavy heat icad conditions the a_rcenc_itioner
may need to run constantly to keep the temperature
you want,
At times using the MED FAN setting to circulate
