INSTALLATION INSTRUCTIONS
Location
The air conditioner should be placed on a hard and level surface strong enough to support the
unit. The unit has casters and it should only be rolled on smooth, flat surfaces. Use caution
when rolling on carpet surfaces. Do not attempt to roll the unit over objects.
Never place any obstacles around the air inlet or outlet and allow at least 20 inch of clearance
for efficient air-conditioning.
Exhaust hose Installation
When you use this air conditioner unit, hot air must be
exhausted out of the room to complete the air
exchange of the condenser. When the unit is operating
in DRY or FAN only mode, no exhaust is required.
1. Pull out about 6” of one end of the exhaust
hose.
2. Install the flat mouth and round exhaust connector
on the exhaust hose by turning counter-clockwise.
See Fig. 18a and 18b
3. Push in the exhaust hose into the air outlet port at
the back of the unit. Fig. 19 and Fig. 20.
4. Only extend the exhaust hose to the necessary
length. We do not recommend extending the
exhaust hose more than 9' long. If you are interested
in purchasing an additional 5’ exhaust hose please
contact [email protected] for retail sales
information.

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 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 button until the COOL indicator light comes on. 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
on 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 4 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 approximately 3 minute
transition time. In dehumidifying mode, do not connect the exhaust hose and let the warm
air return to the room
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
indicator for “Auto” is lit
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

15 | P a g e
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) delay can be set, enabled and disabled
SETTING SWITCH OFF TIMER
With the air conditioner operating in any function mode, press the TIMER button. The TIMER
OFF light will come on. Then set the desired time delay OFF hours by pressing the UP and
DOWN buttons. The time increments are at 0.5 hour to up to 10 hours, followed by 1 hour
increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches off.
To cancel the delayed switch off function, turn off the air conditioner or adjust the time setting to
0.0.
SETTING DELAYED SWITCH ON TIMER
With the air conditioner is off, press the TIMER button. The TIMER ON light will come on. Then
set the desired time delay ON hours by pressing the UP and DOWN buttons. The time
increments are at 0.5 hour to up to 10 hours, followed by 1 hour increment up to 24 hours.
When the delay time set has elapsed, the air conditioner switches on. To cancel the delayed
switch on function, turn on the air conditioner or adjust the time setting to 0.0.
SLEEP MODE
In this mode, the air conditioner gradually increases the set temperature in cooling mode,
decreases the noise level and conserves energy. In Sleep and cooling mode, the set
temperature is increased by 1°C/ 2°C in the first 30 minutes. The temperature will then increase
by another
1°C/ 2°C after an additional 30 minutes. This new temperature will remain the same for 7 hours.
To activate this function mode, press the SLEEP button until the sleep indicated light comes on.
AUTO RESTART
In the event of a power outage, the air conditioner restarts at the previously set function mode
and settings when power is restored.
CONTROLLING THE AIR FLOW DIRECTION
The louvers can be adjusted manually or automatically.
To adjust the air flow direction, manually move the louvers to the desired position. The
maximum setting angle is about 60°.
NOTE: Keep the louver fully opened during operation.
To adjust the air flow direction automatically, press the SWING button to set the louvers at the
desired angle. The louvers move up to an angle of 6° when the SWING button is pressed once.
By pressing the SWING button for more than 2 seconds, the auto swing feature is activated.
NOISE LEVEL
Portable air conditioners may make sounds that are not familiar to you. The sounds listed below
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

16 | P a g e
WATERDRAINAGE
When the water level of the bottom tray reaches
maximum level, the unit will beep 8 times and the
digital display will show P1 symbol. Also, the
cooling or dehumidifying function will stop and
the fan only function will start.
Manual drainage
To drain the water from the bottom try, carefully
move the unit to a drain location, remove the
bottom drain plug and let the water drain
(Fig.25). The P1 symbol will disappear and the
cooling or dehumidifying function can be started.
Continuous drainage
In COOL or DRY modes, remove the upper drain
plug from the back of the unit and install the drain
water hose (5/8 universal female mender) with
¾” hose. Place the open end of the hose to a
drain area. (Fig.23 and 24).

17 | P a g e
REMOTECONTROL
The portable air conditioner can be switched on by the remote control. To transmit signals from
the remote control to the air conditioner, point the front part of the remote handset towards the
control panel on the air conditioner. Reception of the signal is confirmed by a beep. The
maximum signal transmission distance is approximately 8 meters / 26 feet.
NOTE:
Other appliances in the same room controlled by a remote control (TV, radio, stereo, etc.),
may cause interferences
Electronic and fluorescent lamps may interfere with the signal transmissions between the
remote control and the air conditioner
Remove the batteries if the remote control is not used for long periods
