SAFETY

IMPORTANT SAFETY INSTRUCTIONS

The safety instructions below will tell you how to use your room air conditioner to avoid harm to yourself or damage to your ROOM AIR CONDITIONER.

riAV/JaJMM FOR YOUR SAFETY

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. Read product labels for flammability and other warnings.
Awarning
To reduce the risk of fire, electrical shock, or injury to persons when using your air conditioner, follow basic precautions, including the following:
• Be sure the electrical service is adequate for the
model you have chosen.
• If the air conditioner is to be instalied in a window,
you will probably want to clean both sides of the glass first. If the window is a triple-track type with a screen panel included, you may want to remove the screen completely before installation.
• Be sure the air conditioner has been securely and
correctly installed according to the separate installation instructions provided with this manual. Save this manual and installation instructions for possible future use in removing or reinstalling this unit.
• When handling the air conditioner, be careful to
avoid cuts from sharp metal fins on front and rear coils.
Awarning
The complete electrical rating of your new room air conditioner is stated on the serial plate. Refer to the
rating when checWng the electrical requirements.
• Be sure the air conditioner is properly grounded. To minimize shock and fire hazards, proper
grounding is important. The power cord is equipped with a three-prong grounding plug for protection against shock hazards.
• Your air conditioner must be used in a properly
grounded wall receptacle. If the wall receptacle
you intend to use is not adequately grounded or
protected by a time delay fuse or circuit breaker, have a qualified electrician install the proper receptacle.
• Do not run air conditioner with outside protective cover in place. This could result in mechanical damage within the air conditioner.
• Do not use an extension cord or an adapter plug.

ENERGY SAVING IDEAS

• The capacity of the room air conditioner must fit the room size for efficient and satisfactory operation,
• Install the room air conditioner on the shady side of your home. A window that faces north is best because it is shaded most of the day.
• Do not block air flow inside with blinds, curtains, or furniture, or outside with shrubs, enclosures, or other buildings.
• Close the floor and wall registers and the fireplace damper so cool air does not escape up the chimney and into the duct work.
• Keep blinds and drapes in other windows closed during the sunniest part of the day.
• Clean the air filter as recommended in the MAINTENANCE section of this manual.
• Proper insulation and weather stripping in your home will help keep warm air out and cool air in.
• External house shading with trees, plants or awnings will help reduce the air conditioner's work load.
• Operate heat producing appliances such as ranges, washers, dryers, and dishwashers during the cooiest part of the day.

OPERATION

INSTALLATION

Pick a location which will allow you to blow the cold air into the area you want. Windows used for installation must be strong enough to support the weight of the air conditioner. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.
When cooling more than one room, installation is very important since cold air will not turn corners. To cool your rooms, cold air must be blown from the air conditioner in a straight path.

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.
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.
Condenser You may hear
droplets of water
hitting the condenser
causing a pinging or clicking sound.
Fan
You may hear air movement from the fan.
Thermostat As the cooling
system cycles, the thermostat may click.

NORMAL SOUNDS

Aside from the regular fan motor and compressor sounds coming from your air conditioner, you wilt 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.
- 9 -

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. 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 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.

OPERATION

AIR CONDITIONER FEATURES

The controls featured in this manual are
representative of the many models available. Your model may look slightly different.

TEMP

The thermostat will automatically control the temperature of the room. Select a higher number for lower room temperature. The temperature is selected by turning the TEMP knob to the desired position.
The 5 or 6 position is a normal setting for average conditions.

VENT CONTROL

The Vent Control allows the air conditioner to either
recirculate inside air (CLOSE) or exhaust air to the
outside (OPEN).
• 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 normal air passages found in homes.
• The OPEN or CLOSE position can be used with any fan selection.
VERTICAL AIR DIRECTION CONTROL The vertical air direction is adjusted by moving the louver upward or downward.

MAINTENANCE

AIR FILTER CLEANING

The Air Filter will become dirty as it removes dust
from the inside air. It should be washed at least every 2 weeks. If the Air Filter remains full of dust, the air flow will decrease and the cooling capacity will be reduced, possibly damaging the unit.
• Open the inlet grille downward by pulling out the
top of the inlet grille.
• Remove the air filter from fhe fronf grille assembly
by pulling the air filter up slightly.
• Wash the filter using lukewarm water,
• Gently shake the excess water from the filter
completely. Replace the filter.

AIR CONDITIONER CLEANING

Clean the front grille and inlet grille by wiping with a
cloth dampened in a mild detergent solution.
The cabinet may be washed with mild soap or
detergent and lukewarm water, then polished with liquid appliance wax.
To ensure continued peak efficiency, the condenser
coils (weather side at unit) should be checked periodically and cleaned if they become clogged
with soot or dirt from the atmosphere. Brush or
vacuum exterior coils to remove debris from fins.
HOW TO REMOVE THE FRONT
GRILLE
• Remove the TEMP knob and the MODE knob by
pulling.
• Open the inlet grille downward.
• Remove the screw securing the Front Grille.
