BEFORE USING YOUR APPLIANCE

• Remove the exterior and interior packing
• Before connecting the appliance to the power source, let it stand upright for approximately 4 hours. This will reduce the possibility of a malfunction in the cooling system from handling during transportation

SWITCHING ON/OFF THE AIR CONDITIONER
The appliance can be switched ON or OFF by pressing the POWER button on the control panel or the ON/OFF button on the remote control

COOLING MODE
In this mode, the air conditioner cools and dehumidifies the room. To activate this function mode, press the MODE button until the COOL indicator light is displayed. When the cooling mode is set, the compressor will start in approximately 3 minutes. In cooling mode, hot air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the hot air.
The temperature setting range of this air conditioner is from 62°F / 17°C to 88°F / 30°C. To set the temperature, press the + or - buttons. This air conditioner has a 5°F temperature cushion which if the set temperature is within 5°F of the ambient temperature, the unit runs in fan only mode. This saves energy and prolongs the life of the compressor of the air conditioner.
To set the fan speed, press the FAN button. In cooling mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.

DRY (DEHUMIDIFYING) ONLY MODE
In this mode, the air conditioner only dehumidifies the room, the compressor will activate intermittently depending on the ambient temperature and the fan speed is set to LOW. To activate this function mode, press the MODE button until the DRY indicator light is displayed. Please note that when switching function mode, there will be an approximately 3 minute transition time. In dehumidifying mode, the exhaust hose does not need to be vented. If the exhaust hose is vented, the room will be cooled as it dehumidifies. To prevent cooling, remove the exhaust hose from the window kit and allow the warm air from the rear to be re-circulated into the room. If room temperature is higher than 77°F, the fan speed can be adjusted. If room temperature is lower than 77°F, the fan speed is set at Low.
NOTE: When using dehumidifying mode, venting the exhaust hose to the outside is not required. If vented, the warm air is exhausted to the outside and cooling within the room may occur. Additionally, if the exhaust hose is not vented, the unit may require more frequent draining. Also, the air conditioner does not have a humidistat in which a specific humidity level can be set.

AUTOMATIC MODE
When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending on the temperature of the room. The fan speed is automatically selected and cannot be changed. To operate the unit in Auto mode when the unit is on, press the MODE button until the AUTO indicator light comes on.

HEAT MODE
In this mode, the air conditioner heats the room. To activate this function mode, press the Mode Control button until the HEAT indicator comes on. When the heating mode is set, the compressor will start in approximately 3-5 minutes; the rear fan will start first, followed by the compressor then the air output fan into the room. It may take several minutes heat to blow from the front air output vent.

• In heating mode, cold air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the cold air.
• The temperature setting range is from 61F to 77F. To set the temperature, press the + or – buttons. Once the set temperature is achieved, the compressor and the fan will stop.
• To set the fan speed, press the Fan Speed button. In heating mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.

NOTE: This unit uses heat pump from heating and the heating mode does not work when temperature is below 45F.

FAN ONLY MODE
In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode, press the MODE button until the FAN indicator light comes on. In this function mode, the temperature cannot be set. Subsequently, set the desired fan speed by pressing the FAN button. When using FAN only mode, venting the exhaust hose to the outside is optional.
