Functions Setting
This portable air conditioner has three functions: cooling, dehumidifying and fan. Fan
has two speeds: high speed and low speed, setting temperature is 17--30℃（62～86
℉）, 24 hours timer, sensor and water-level protective function.
Buttons:There six keys on the control panel: POWER，Mode，Fan Speed, Timer, Up key and
Down key .
a). POWER Key: Press the key to start the unit ,and press this key again to turn unit off.
b). Mode Key: Set the Cooling , Dehumidifying and Fan Mode when unit is working or
Timer-On Situation.
c).Fan Speed: From pressing the button , fan speed change by low - high - low loop
manner, but not available in dehumidifying mode.
d). Timer Key: Can set the Timer-Off function in unit working situation, when setting the
time,the Regular time indicator will illumine; can adjust the time again while the Regular time
indicator will illumine; then it will display the room temperature again in the Off mode. Can also set in the
Timer-On function,same as above setting.
After the Timer-Off or the Timer-On, the Timer indicator lights.
e).Up\Down Key: Press this two key to set the desired room temperature.(Press the Up
key once,the temperature will increase by 1℃or 1℉, also press the down key to decrease by 1℃or 1℉),
can also set the time in Timer Situation; can also exchange from ℃to ℉display by pressing these two
keys at the same time.
* the user wants to display the temperature in ℃, you can use the button on the remote controller or press the
up and down key simultaneously.
Operation instructions:
a) In the Cooling models:
Ta≥Ts+1℃(1℉), the cooling starting.
Ta≤Ts－1℃(1℉), the compressor stops and only the fan motor remains working at
the set fan speed.
Ta：Room Surrounding Temperature Ts：Setting Temperature
In the mode,pressing Timer and Down button can set sleep function, In sleep
function, After operating two hours, the set temperature increases 1℃(1℉)
automatically. After operating for another 2 hours, the set temperature will
increase 1℃(1℉) again. Then, the set temperature will not change and the
fan is forced to switch to low level.

b) In the dry mode, if the ambient temperature ≥17℃(62℉), the compressor
will start.Then, the unit is controlled in the following manner: when the ambient
temperature ≤15℃(59℉), the compressor shuts down. When the ambient
temperature raise to be ≥17℃(62℉), the compressor starts again. The start
/stop of the compressor meets the requirement for 3-minute protection time.
c). Under the fan mode, fans runs on both high speed or low speed. Temperature
setting is in vain, unit just displays environment temperature between 10-35℃（50～95℉）
3) Timer setting
a) Upon start, press the Timer button to enter timed shutdown. Upon shutdown, press
this button to enter timed start. In the meanwhile, the timer indicator will illuminate.
b) Press the Timer button to enter the timing function (timed start/timed shutdown).
Adjust the up or down button to set the timing time. The time will cycle in the order of
1－2－3－……24－0－1 hours or 24－23－22－……1－0－24 hours. The
adjustment time of the timing function is relative time.
c) After timed start is set, once the timed start time is reached, the unit will start. In the
meanwhile, the timer indicator will extinguish and the ambient temperature is displayed.
d) After timed shutdown is set, once the timed shutdown time is reached, the unit will
shut down. In the meanwhile, the timer indicator will extinguish and the ambient temperature is displayed.
e) Only the last setting of the timing function is valid and valid once only.
f) ON/OFF operations caused by the button or remote control will clear all timing settings.
g) Once the timing is determined, if the timer button is pressed once, it is possible to
query the remaining timed start/shutdown time. If the timer button is pressed twice
continuously within 5s, it is possible to cancel timing.
6). The up button and down button may be used to change the set value of the temperature.
Two. Operation instructions of the remote control
The operation instructions of the buttons of this simple remote control are as follows:
1. Power button: press this button to turn on/off the unit;
2. Timer button: upon shutdown, press this button to set timed start; upon start, press
this button to set timed shutdown.
3. High button: press this button to allow the unit to operate in the high fan speed state
(except in the dry and sleep modes);
4. Low button: press this button to allow this unit to operate in the low fan speed state;
5. Up button: press this button to increase the temperature and timing value;
6. Down button: press this button to decrease the temperature and timing value;
7.℃ — F button: press this button to switch between the Celsius degree and Fahrenheit degree;
8. Cool button: press this button to set this unit to operate in the cooling mode;
9. Fan button: press this button to set this unit to operate in the air supply mode;
10. Dry button: press this button to set this unit to operate in the dry mode;
11. Sleep mode: press this button to set this unit to operate in the sleep mode.
Three. Multiple protection functions:
1. Anti-freeze protection function:
Upon cooling, when the compressors operates continuously for more than 10
minutes, if the pipe temperature Tp is less than or equal to 2℃continuously for 20

seconds, the compressor and water spraying motor turn off, other loads operate and
LED displays E4, the unit initiates the anti-frost protection function and the buttons are
inactive (except the OFF button). Once the pipe temperature rises to exceed or equal 8
℃, the protection is relieved, the original status is restored and the unit meets the
requirements for 3-minute delay protection of the compressor.
二. Full water protection function:
When the water in the water tray exceeds the alarm level, the unit will alarm
automatically and the full water indicator illuminates. In this case, you need to drain the
condensate in the unit; otherwise, the unit will shut down automatically after the buzzer
gives off 5 beeps. (For more information about the drain method, refer to the “Drain”). If
the unit is not shut down manually, the unit will be restored to the previous operating
status automatically once the water is fully drained. Or the power may be turned on
again to start the unit.
三. Delay protection function of the compressor
This unit offers restart protection for the compressor. Except that the compressor
may start immediately when the unit is energized for the first time, there is 3-minute
delay start protection after the compressor is shut down.
