15 amp or more, AC only as shown on right. '' *
Use of an improper voltage rating power circuit can result in
damage to the unit and possibly fire.
• Aiways use a fuse with the proper amp rating.
Do not, under any circumstances, use wire, pins or other objects in place of the proper fuse.
• Use of extension cords of any kind is not recommended.
If you still elect to use an extension cord, it is absoiutely necessary that it be a UL Listed 3-wire grounding
type appliance extension cord rated 125 Volts, 15 amp or more.
• Ventiiate the room periodicaiiy during use, especiaiiy if using gas appiiances.
3-pronged Grounding
Receptacle 15 Amps. 125V.
GROUNDING INSTRUCTIONS
WARNiNG: Improper use of the grounding piug can resuit in the risk of electric shock.
This appiiance must be grounded, in the event of an electricai short circuit, grounding reduces the risk
of eiectric shock by providing an escape wire for the electric current.
This appliance is equipped with a cord having a grounding wire with a grounding plug.
The plug must be plugged into an outlet that is properly installed and grounded.
WARNiNG: Do not under any circumstances cut or remove the round grounding prong
from this piug.
If it Is necessary to use an extension cord, use only a UL Listed 3-wire extension cord that has a 3-
blade grounding plug, and a 3-slot receptacle that will accept the plug on the appliance.
The marked rating of the extension cord shouid be AC 125 Voit, 15 Amp or more.
Consult a qualified electrician or serviceman if the grounding instructions are not compieteiy under
stood, or if doubt exists as to whether the appliance is properly grounded.
If a grounding adapter is used, make sure the receptacle box Is fully grounded.
Allow 3 minutes for the compressor to restart cooling.
If you turn the air conditioner off and immediately restart it, allow three minutes for the compressor to
restart cooling. There Is an electronic device in the unit that keeps the compressor off for three minutes.
When power failure occurs
This air conditioner has a memory function to store settings when a power failure occurs. After power
recovery, the unit will automatically re-start in the same settings which were active before the power
failure.
Dehumidifying function
The air conditioner removes moisture from the air in your room.
Cooling operation under iow temperatures: is your unit freezing up?
The unit operates on inside and outside temperatures. Freezing can occur when the temperature is set
close to 64°F and when there are low outside temperatures, especially during the night hours. At these
conditions, a further temperature drop may cause the unit to freeze. Setting the unit to a higher
temperature will prevent it from freezing.
ENERGY EFFICIENCY TIPS
Setting the proper temperature.
For optimum energy efficiency, keep the difference between the inside and outside temperature within
10°F(5°C). Do not keep the temperature setting any lower than is necessary for you to feel comfortable.
Generally, 78 °F to 80°F(26°C to 27 °C) is a comfortable summer indoor temperature.
When you turn the unit on, do not set the temperature higher than the room temperature at start up as
this will not allow the compressor to cycle and maintain a comfortable room temperature.
Avoid direct suniight.
Close blinds, drapes or shades to keep out direct sunlight during cooling operation.
Keep the filter clean.
Keeping the filter clean greatly aids efficient operation. A dirty filter blocks the flow of air, making your air
conditioner work harder and less efficiently. See page 17 on how to clean the filter.
Turn off unnecessary light.
Your air conditioner must remove the heat produced by your lights or other heat-producing appliances.
Turn off lights or appliances that are not in use.
Install your air conditioner In a shady location.
Direct sunlight on a window air conditioner increases its workload and will increase its operating cost.
Don't let cool air escape.
Close windows and outside doors. Do not keep doors open and let hot air rush in. improperly installed
air conditioners and improperly weatherstripped doors and windows will let hot air in and the cool air out.
Turn off air conditioner when no one is home.
Use only when necessary. The fewer hours a room air conditioner is used, the lower the operating cost.

CLEANING AND MAINTENANCE
CLEANING THE FILTER
If the filter is clogged with dust, the amount of air flow will
be reduced, resulting in poor cooling performance. The
filter should be cleaned every 10 days. At the beginning of
every cooling season or after a long period of inactivity,
clean the filter before starting the unit.
4 REMOVE THE FILTER
* Open the front panel and get the filter out.
CLEAN THE FILTER
To remove dust from the filter, use a vacuum cleaner
or wash it in clean water.
If the filter is very dirty, wash it with detergent and
rinse carefully with clean water. Dry the filter with
a soft cloth.
Do not expose the filter to heat or dry it in direct
sunlight.
RE-INSTALL THE FILTER
Put the filter into its original position and close the
front panel.
Never operate the unit without installing the filter. It
may result in serious damage to the unit.
CLEANING OF THE FRONT PANEL AND CABINET
To clean the front panel and cabinet, wipe with a soft, dry cloth or with a cloth moistened with a
mild soap. Rinse carefully by wiping with a damp cloth and dry completely.
Avoid splashing the unit with water. Excess water can damage electrical insulation and result in
danger.
Never use harsh chemicals or abrasive cleaners on any part of the unit. To avoid damage to the
unit, do not use hot water (120T / 501) or more) when cleaning.
OILING OF THE COMPRESSOR AND FAN MOTOR IS
UNNECESSARY
The compressor is permanently lubricated and is hermetically sealed. The fan motor is
lifetime sealed and does not require oiling.
REMOVING THE AIR CONDITIONER
Before removing the air conditioner,operate the unit in the FAN mode with high fan speed
on a dry day, for about half a day to thoroughly dry the water inside the air conditioner unit.

AIR CONDITIONER DOES NOT OPERATE AT ALL
• Is the unit plugged in or is the plug loose?
• Is the fuse blown or the circuit breaker tripped?
• Did you restart the unit within 3 minutes after a power failure? If the power was off for less than 3
minutes, and you restarted the air conditioner within 3 minutes, a protective device may cause the
compressor to shut off, preventing cooling for about 5 minutes.
AIR CONDITIONER DOES NOT PROPERLY COOL
• Is the MODE set to fan only Mode?
Cooling will not take place in the fan only mode.Change the MODE setting.
• Is the filter clogged with dust?
A dirty filter can cause the cooling coils to freeze. If this happens, clean the filter and
replace. Run the air conditioner on the MED FAN setting until all ice dissipates.
• Is the temperature set properly?
If your room is too warm, adjust the temperature setting lower.
• Is the window exposed to direct sunlight?

Close all windows and doors for maximum cooling.
17
Page 18
BEFORE CALLING FOR SERVICE
NOTE: WATER IN BOTTOM OF TRAY
• Water will collect in the bottom tray of the unit. This is normai. Water condenses on the evaporator
coii at the front of the unit and is channeied to the rear where it is picked up by the condenser fan.
The water is biown onto the condenser coil fins and this creates a "splashing" noise which is normal.
If excess water builds up in this tray it will drain outside through a grooved channel in the tray.
• The operating sound may seem rather loud for 2 to 3 minutes when the unit is first turned on. This
is the sound of the compressor's start-up and is normal.
• A soft, swishing noise can be heard immediately after the unit is turned on or off, and also during
operation. This is the sound of the refrigerant flowing inside the unit.
