NOTE
All the pictures in this manual are for illustrative purposes only. The actual shape of the air conditioner you purchased may be slightly different, but its operations and fuctions are similar.

Air Conditioner Operation

WARNING
To reduce the risk of fire, electrical shock, or injury to people or property, read the SAFETY PRECAUTIONS before operating this appliance.
NOTE
The cool circuit has an automatic 3 minutes time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping

To quickly begin operating the air conditioner, follow these steps:

1. Set the thermostat to the lowest number (coldest setting).
2. Set the selector control to the highest COOL setting.
3. Adjust the louver for comfortable air flow (see Air Directional Louvers).
4. Once the room feels colder, adjust the thermostat to the setting you find most comfortable.
5. Make sure that the air flow inside and outside are not obstructed by anything.
6. This air conditioner is designed to be operated under conditions as follows:

Cooling Operation

• Outdoor temp.: 18-43°C (64°F ~ 109°F)
• Indoor temp.: 17-32°C (62°F ~ 90°F)

NOTES

• The relative humidity of room should be less than 80%. If the unit is used in a condition with a relative humidity over 80%, there will be condensed water on the surface of the unit.
• Performance may be reduced outside of these operating temperatures.

Before you begin, thoroughly familiarize yourself with the control panel as shown below and all its functions, then follow the symbol for the functions you desire. The unit can be controlled by the unit control panel alone or with the remote controller.

Key Pad Features

(ON/OFF) Button

The unit will initiate automatically the Energy saver function under Cool, Dry, Auto (only Auto-Cooling and Auto-Fan) modes.

NOTE

If the unit turns off unexpectedly due to a power outage, it will restart with its previously set fuctions when the power resumes.

(UP/DOWN) Button

Press or hold either left (-) or right (+) button until the desired temperature is seen on the display. This temperature will be automatically maintained at the set temperature, between 62°F (17°C) and 86°F (30°C). If you want the display to read the actual room temperature, see "To Operate on Fan Only” section.

(MODE) Button

• To choose operating mode, press Mode button. Each time you press the button, a mode is selected in a sequence that goes from Auto, Cool, Dry and Fan. The indicator light beside will be illuminated and remains on once the mode is selected.
• The unit will initiate automatically the Energy Saver function under Cool, Dry, Auto (only Auto-Cooling and AutoFan) modes.

Operating on AUTO mode:

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

Operating on FAN mode:

• 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.
• 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 can not be adjusted.

Operating on DRY mode:

• In this mode, the air conditioner will operate in the form of a dehumidifier. Since the conditioned space is a closed or sealed area, some degree of cooling will continue.

(FAN SPEED) Button

• Used to select the Fan Speed in four steps - Auto, Low, Med or High. Each time the button is pressed, the fan speed mode is shifted. On Dry mode,the fan speed is controlled at low automatically.

(ENERGY SAVER) Button

This function is available on COOL, DRY, AUTO (only AUTO-COOL and AUTO-FAN) modes. 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.

(SLEEP) Button

In this mode the selected temperature will increase by 2°F/1°C 30 minutes after the mode is selected. The temperature will then increase by another 2°F/1°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.

(TIMER) Button

• When the unit is on or off, first press Timer button, the TIMER ON indicator light illuminates. It indicates the Auto Start program is initiated.
• When the time of TIMER ON is displayed, press the Timer button again, the TIMER OFF indicator light illuminates. It indicates the Auto Stop program is initiated.
• Press or hold either left (-) or right (+) button to change the Auto time by 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.
• The selected time will register in 5 seconds, and the system will automatically revert back to display the previous temperature setting or room temperature when the unit is on. (when the unit is off, there is no display.)
• Turning the unit ON or OFF at any time or adjusting the timer setting to 0.0 will cancel the Auto Start/Stop timed program.
