HOW AND WHY
Your room air conditioner
provides
the following
functions
to make hot weather
iiv[ng more
comfo_able:
• Coo_s and circulates room air
* Lowers humidity by removing excess moisture.
, Filters out summertime dust, diR. 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- coo_er, drier, and cleaner. Moisture
removed from the room air is carried to the outside
and evaporated.
'(our air conditioner is designed to be easy to
operate and to provide pienty of cooling power.

Aside from the r_ular fan motor and compressor
sounds coming from your air conditioner, you will

CAPACITY AND RUNNING TIME
Proper unit size is impo_ant in deciding the desired
comfort for the area you want to cool. An
undersized unit will not have the capability to cool,
_eaving the area uncomfortably warm. The proper
size is determined by the number of square feet in
the area to be _l_,
indoor and outdoor
temperature and humidity.
Whenever the heat or humidity load is a_ve
normal
the air _nditioner
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
r_m air may make it comfortable even though Lhe
air is not being cooled. This will decre_e
your cost
of use.
