MONEY SAVER

The fan stops when the compressor stops cooling.

• Approximately every 3 minutes the fan will turn on and sample the room air to determine if more cooling is needed.

TEMPERATURE SETTING

• These buttons control the temperature of the room.

The temperature can be set within a range of 60°F to 86°F, in increments of 1°F.

ON/OFF TIMER

ON–When the air conditioner is off, it can be set to automatically

come on in 1 to 12 hours from its previous setting. Each touch will increase the timer by 1 hour. OFF–When the air conditioner is on, it can be set to automatically turn off in 1 to 12 hours. Each touch will increase the timer by 1 hour. After the timer has been on for 30 minutes, the temperature will automatically rise 2°F, and after another 30 minutes, it will automatically rise 2°F again. The temperature will then stay the same until the timer goes OFF.

To cancel the timer, press the TIMER pad until the display time disappears.

POWER

• To turn the unit ON, push the button. To turn the unit OFF, push the button again.

• This button takes priority over any other buttons.

• When you first turn it on, the unit is on the High cool mode and the temp. at 72°F

FAN SPEED

• Everytime you push this button it will rotate between the following fan speeds:

High (F3) → Low(F1) → Medium (F2) → High (F3)
