OPERATION INSTRUCTIONS
BEFORE USING YOUR PORTABLE AIR CONDITIONER
Remove the exterior and interior packaging.
Before connecting the unit 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 unit can be switched ON or OFF by pressing the Power button on the control panel or
the Power 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 Control button until the indicator comes on. When the cooling
mode is set, the compressor will start in approximately 3 minutes.
NOTE: 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 61°F to 89°F. 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 compressor of the air conditioner.
Once the set temperature is achieved, the fan runs continuously.
To set the fan speed, press the Fan Speed 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.
DEHUMIDIFYING 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 Control button until the indicator comes on.
Please note that when switching function mode, there will be an approximately 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.
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 Control button until the indicator comes on.
In this function mode, the temperature cannot be set. Subsequently, set the desired fan
speed by pressing the Fan Speed button. Fan Only mode requires that the exhaust hose be
removed.
NOTE: The unit does not need to be vented in Fan Only mode.

12 | P a g e

are normal. Noise reflecting off hard surfaces such as a floor or wall can make the sounds seem
louder than they actually are.
The compressor may make a pulsating or high-pitched sound.
Water running from the evaporator to the water tank may make a splashing sound.
Refrigerant flowing may make a gurgling sound.
Fan sound may come from front and back air vents.
WATER DRAINAGE
During the process of cooling, some water will be extracted from the air into the unit. Most of
this water is used to cool and exhausted to the outside. If the unit is operated in high humidity or
low temperature environment, water will collect in the reservoir inside the unit. If the reservoir is
full, the compressor will stop. To continue the cooling function, please drain the water.
1. Turn off the unit.
2. Position a flat container or dish under the drain plug.
3. Remove the drain plug and the condensed water will drain out automatically.
