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 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 approxi-

mately 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 what temperature you have selected and the room temperature is close to the unit. 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. When using FAN only mode, venting the

exhaust hose to the outside is optional.

TIMER (DELAYED SWITCH ON / OFF) FUNCTION

This function mode enables a delayed switch ON or delayed switch OFF of the air conditioner. The time (hours) de-

lay can be set, enabled and disabled.
