Important Safety Instructions

WARNING Avoid fire hazard or electric shock. Do not use an extension cord or an adaptor plug. Do not remove any prong from the power cord.

Grounding type wall receptacle

Power supply cord with 3-prong grounding plug

Read all instructions before using this air conditioner.

WARNING

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.

• Be sure to unplug the unit before cleaning or performing other maintenance to prevent electric shock or fire which could cause serious injury or death.

WARNING

Prevent Accidents
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. This information can be found on the serial plate, which is located either on the side of the cabinet or behind the grille.
• If the air conditioner is to be installed 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, 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 the 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

WARNING

Electrical Information
The complete electrical rating of your new room air conditioner is stated on theserial plate. Refer to the rating when checking 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

• Do not block air flow inside with blinds, curtains or furniture; or outside with shrubs, enclosures, or other buildings.
• 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.
• Close the fireplace damper, floor and wall registers 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 section “Care and Cleaning.”
• Proper insulation and water 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 coolest part of the day

Using Air Conditioner

NOTE : If the air conditioner is turned off, wait 3 minutes before restarting. This allows pressure inside the compressor to equalize. Failure to follow these instructions may cause inefficient operation.

WARNING To reduce the risk of fire, electric shock, or injury to persons, read the IMPORTANT SAFETY INSTRUCTIONS before operating this appliance.

To begin operating the air conditioner, follow these steps:

1. Plug in the air conditioner. (To prevent electrical hazards, do not use an extension cord or an adapter plug.)
2. Set the thermostat to the highest number (coldest or cooler setting).
3. Set the selector control to the highest FAN or COOL setting (see below).
4. Adjust the louvers for comfortable air flow (see Air Directional Louvers).
5. Once the room has cooled, adjust the thermostat to the setting you find most fordable.

Review the “Air Conditioner Features” section for other settings.

Air Conditioner Features

The controls featured in this manual are representational of the many models available. Your model may offer slightly different features.

Selector Control
The selector control turns the unit on or off and allows a choice of either cooling room air, circulating room air at the existing temperature, or heating room air.

COOL/FAN
Operate COOL/FAN modes according to the following suggestions:

• ON/OFF or OFF = Turns air conditioner on and off.
• HIGH COOL = Maximum cooling speed. Begin operation of the air conditioner in this mode.
• LOW COOL = Fan runs slow for quiet operation when maximum cooling is not  needed.
• HIGH FAN = Maximum air circulation without cooling.
• LOW FAN = Slow air circulation without cooling.

HEAT
The HEAT selection provides quiet, efficient circulation of warm air. Turn the selector to the HEAT setting and set the thermostat at WARMER setting. When the HEAT setting is selected, the thermostat maintains the temperature by automatically turning the heater on and off in response to room temperature. The fan runs continuously to circulate air in the room

Once the room is warm, adjust the thermostat to a less warm position. This provides less heat, or cooler temperatures.

A slight heat odor may come from the unit when first switching to HEAT after the cooling season is over. This odor, caused by fine dust particles on the heater, will disappear quickly

Automatic Thermostat
When a COOL or HEAT setting is selected, the thermostat controls the amount of cooling or heating by automatically turning the cooling compressor or heater on and off in response to the room temperature.

Air Conditioner Features (continued)

Automatic Thermostat (continued)
Set the thermostat at the COOLER setting for cooling, and the warmer setting in  the HEAT mode. Once the room has reached the desired temperature, adjust the thermostat to a setting providing the most comfortable amount of cooling or heating. COOLER provides lower room temperatures. WARMER provides higher room temperatures.

Night Time Cooling
When outside temperatures drop below 70°F (21°C) and the unit is cooling, frost may form on the coils and block airflow into the room. If this occurs, operate the air conditioner on the FAN setting to defrost the coil.

If cooling while the outside temperature is low, set the thermostat to the middle position. Make sure the louvers are open. This will help prevent frost build-up.

Air Directional Louvers
Air directional louvers control air flow direction

Way Louvers
The 4-Way air directional louvers allow you to direct air flow up or down, left or right throughout the room as needed. To adjust the air directional louvers side-topside, use the center handle as you move it side-to-side.

Care and Cleaning

Clean your air conditioner occasionally to keep it looking new.
WARNING Be sure to unplug the unit before cleaning to prevent electric shock or fire hazards.

Air Filter Cleaning
The air filter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the filter can build up and cause an accumulation of frost on the cooling coils.

• Tilt the Horizontal Louvers in the UP position, before pulling the filter out.
• Grasp the filter by the center and pull up and out.
• Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly. Gently shake excess water from the filter. Be sure filter is thoroughly dry before replacing.
• Or, instead of washing you may vacuum the filter clean
  

Cabinet Cleaning

• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in absolution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.

• Never use harsh cleaners, wax or polish on the cabinet front.

• Be sure to wring excess water from the cloth before wiping around the controls.
  Excess water in or around the controls may cause damage to the air conditioner.

• The cabinet front can be removed for more thorough cleaning. Refer to “Front
  Removal” in this manual.

• Clean the front in a sink using liquid dishwashing detergent and warm water. Rinse
  thoroughly and dry.

• Replace cabinet front. Replace the screws.

• Replace front panel (if applicable) and filter. Plug in air conditioner
  

Front Removal
To remove the front for more thorough cleaning follow these steps:

• Unplug power cord from the wall outlet.
• Remove knobs by firmly pulling (these knobs are interchangeable).
• Remove the filter to expose the two (2) screws holding the front in place.
• Remove the two (2) screws and save for replacing.
• Press firmly on each side of the cabinet close to the front, approximately half way down.
• While pressing on the sides of the cabinet, gently pull the front out and lift up to release it from the cabinet.
• Clean as instructed in Care and Cleaning. Reinstall the front when dry by reversing the above instructions.
