OPERATION INSTRUCTIONS

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 but-
ton 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 comes on. When the cooling mode is set, the compressor will start in approxi-
mately 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 on fan only mode. This saves energy and prolongs the life of the compres-
sor 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 comes on. Please note that when switching function mode, there will be an approxi-
mately 3 minute transition time. In dehumidifying mode, do not connect the exhaust hose and let the warm air return
to 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 the Dehumidifying mode, the air exhaust hose should not be vented to the outside. If the warm
air is exhausted to the outside, cooling may occur. Additionally, you must manually drain the water from the unit.
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.
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. Fan Only mode requires that the exhaust
hose be removed.
