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
FIG.12
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. An
undersized
unit will not have the capability
to cool,
leaving
the area uncomfortably
warm.
The proper
size is determined
by the number
of square
feet in
the area to be cooled,
indoor
and outdoor
temperature
and humidity.
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.
At times using the MED FAN setting
to circulate
the
room air may make it comfortable
even though
the
air is not being cooled.
This will decrease
your cost
of use.
Compressor
The modern
high efficiency
compressor
may have a high
pitched
hum or pulsating
noise that cycles
on and off.
Unit Vibration
The unit may vibrate
and make noise
because
of poor wall
or window
construction.
Fan
You may hear air
movement
from
the fan.
You may hear droplets
of water
hitting
the condenser
causing
a pinging
or
clicking
sound.
