To operate on Auto feature:

• When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending on what temperature you have selected and the room temperature.
• The air conditioner will control room temperature automatically round the temperature point set by you.
• In this mode, the fan speed cannot be adjusted, it starts automatically at a speed according to the room temperature.

To operate on Fan Only:

• 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 when Fan Only mode is selected.
• During this function, the display will show the actual room temperature, not the set temperature as in the cooling mode.
• In Fan only mode, the temperature is not adjusted.

To operate on Dry mode:

- In this mode, the air conditioner will generally operate in the form of a dehumidifier. However, some degree of cooling will continue.

TO USE THE ENERGY SAVER FEATURE

This function is available on COOL mode. The fan will continue to run for 3 minutes after the compressor shuts off. The fan then cycles on for 2 minutes at 10 minute intervals until the room temperature is above the set temperature, at which time the compressor turns back on and Cooling Starts.

AIR CONDITIONER FEATURES (CONTINUED)

SLEEP FEATURE:

- In this mode the selected temperature will increase by 2^ F/1(or 2^ C 30 minutes after the mode is selected. The temperature will then increase by another 2^ F/1(or 2^ C after an additional 30 minutes. This new temperature will be maintained for 6 hours before it returns to the originally selected temperature. 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.
