OPERATION
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.
NORMAL SOUNDS нс. 21
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. An oversized unit will cool,
but not dehumidify, leaving the area cool and damp.
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 heed to run constantly to keep the temperature
you want.
At times using the HIGH 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.
Fan
You may hear air
movement from the
fan.
Unit Vibration —
The unit may vibrate
and make noise
because of poor wall
or window
construction.
—— Condenser
You may hear
an
droplets of water
hitting the condenser,
causing a pinging or
clicking sound.
Compressor
The modern high
efficiency compressor
may have a high
pitched hum or
pulsating noise that
cycles on and off.

USING THE AIR CONDITIONER
To reduce the risk of fire, electric
shock, or injury to persons, read the important
SAFETY instructions section before operating this
appliance
To begin operating the air conditioner after
installation, follow these steps:
1. Plug in the air conditioner.(To prevent electrical
hazards, do not use an extension cord or an
adapter plug.)
. Set the exhaust vent to the CLOSE position.
. Set the TEMP Control to the coolest setting.
. Set the MODE Control at the highest COOL level.
. Adjust the louvers for comfortable air flow.
. Once the room has cooled, adjust the TEMP and
MODE control to the setting you find most
comfortable.
© N SS Ye NM
NOTE : If the air conditioner is turned off, wait 3
minutes before restarting. This allows pressure
inside the compressor to equalize. Failure to wait 3
minutes before restarting may cause inefficient
operation.
If you move the TEMP Control to a warmer, then
Immediately back to a cooler setting, the unit will
shut off. Wait 3 minutes before restarting.
VENT CONTROL
The Vent Control allows the air conditioner to either
recirculate inside air (CLOSE) or exhaust air to the
outside (OPEN). (FIG. 23)
* The CLOSE position is used when maximum
cooling is desired. It may also be used for air
recirculation without cooling when the air
conditioner is set in the FAN position.
* The OPEN position removes stale air from the
room and exhausts it to the outside. Fresh air is
drawn into the room through your home's normal
air passages.
* The OPEN or CLOSE position can be used with
any fan selection.
