Operating Instructions

TO TURN UNIT ON:

YOU WILL SEE:

TO CHANGE TEMPERATURE SETTlNG:

YOU WILL SEE:

Note: Tap or hold either up (^ ) or down (v ) button until the desired temperature is seen on the display. This tempe- rature will be automatically maintained anywhere between 60 °F (16 °C) and 90 °F (32 °C) . If you want the display to read the actual room temperature. See "To Operate on Fan Only" section on Page 7.

TO ADJUST FAN SPEEDS:

YOU WILL SEE:

TO USE AUTO FAN FEATURE:

YOU WILL SEE:

Note: Fan starts at High Speed and adjusts to a slower speeds the room temperature dictates. For example, if the room doesn't get too warm, it will stay at the slowest speed. If the room temperature rises quickly, such as a door being opened, it will automatically go to the highest speed. The fan speeds will re-adjust back to the slowest speed as the room returns to the original set temperature. Press either the fan slower or fan faster button to adjust the fan speed manually.

TO OPERATE ON FAN ONLY:

YOU WILL SEE:

Note: Use this function only when cooling is not desired, such as for room air circulation or to exhaust stale air on some models. (Remember to open the vent during this function, but keep it closed during cooling for maximum cooling efficiency.) You can choose any fan speed you prefer. (Except “Auto Fan”).

During this function, the display will show the actual room temperature, not the set temperature as in the cooling mode.

TO USE THE ENERGY SAVER (ECON) FEATURE:

YOU WILL SEE:

Note: In this mode, the fan will continue to run for 1 minu-te after the compressor shuts off. The fan then cycles on for 20 seconds at 10 minute intervals until the room tempe- rature is above the set temperature, at which time the com- pressor turns back on.

SLEEP FEATURE:

YOU WILL SEE:

Note: In this mode the selected temperature will increase by 2 °F 30 minutes after the mode is selected. The tempe- rature will then increase by another 2 °F after an additional minutes. This new temperature will be maintained for 7 hours before it returns to the originally selected tempera- ture. This ends the "Sleep" mode and the unit will continue to operate as originally programmed. The "Sleep" mode program can be cancelled at any time during operation by again pressing the "Sleep" button.

TIMER: DELAY STOP / START FEATURE

YOU WILL SEE HOW MUCH TIME IS CHOSEN:

Note: For Delay Stop, the unit must be in the On position.

Note: For Delay Start, the unit must be in the Off position.

First, Press TIMER button, then adjust timer setting, tap or hold the UP arrow ( ) or the DOWN arrow ( ) to change delay timer at 0.5 hour increments, up to 10 hours, then at 1 hour increments up to 24 hours. The control will count down the time remaining until start (8, 7.5, 7, etc.). The Delay Start Operation automatically selects cooling with maximum Fan speed (if Cool, Energy Saver, or Fan Only was the last mode selected) . The temperature maintained will be the same as previously set. To change the set temperature, press "COOL" then Up or Down arrows until the desired temperature is indicated on the display. After 5 seconds, the control will automatically change the display back to the hours remaining until the unit will start/stop. Pressing the unit On/Off button at any time will cancel the Delay Start/Stop function. The Delay Start/Stop Feature will work until the unit either starts or stops. Once that happens the above steps have to be repeated again.

CHECK FILTER FEATURE, YOU WILL SEE:

Fresh Air Vent Control (on some models)

The Fresh Air Vent allows the air conditioner to:

1. Recirculate inside air - Vent Closed (see Fig. 1)
2. Draw fresh air into the room - Fresh Air (see Fig. 2)
3. Exchange air from the room - Vent Open (see Fig. 3)

Air Directional Louvers

Air directional louvers control air flow direction. Your air conditioner has the louver type described below.

Auger Type

The louvers will allow you to direct the air flow Up or Down and Left or Right throughout the room as needed. Rotate the Auger Wheels until the desired Left/Right direction is obtained. Pivot horizontal louvers until the desired Up/Down direction is obtained.

Care and Cleaning

Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to prevent 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.

• Push the vent handle to the Vent Closed position(where applicable).
• Open the front panel.
• 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 a solution 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.
• Plug in air conditioner.

Winter Storage

If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.

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 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 coolest part of the day.
