CLEANING THE AIR FILTERS

The air filter must be cleaned by profressional.

CLEANING THE UNIT THE ENCLOSURE

Clean the enclosure of the air conditioner and the 
remote control with dry cloth or a vacuum 
cleaner. If damp cloth is used, remove molsture 
by using dry cloth afterward.

Once the U-TOUCH stars appear, the remote will send a signal of the remote-local temperature to the indoor unit, 
and this remote-local temperature will supersede the return air temperature as the unit's target temperature. 
Every 10 minutes such signal will be sent from the remote to the indoor unit updating the remote-local 
temperature. If at any time during this process no signal is received by the indoor unit from the remote, the unit 
will switch back to the previously set temperature before the U-TOUCH feature is activated. To turn the U-
TOUCH feature off, simply press the U-TOUCH button until you see the symbol disappear from the remote 
screen. By doing so, the return air temperature will take place of remote-local temperature as the unit's target 
temperature. U-TOUCH is what YOU WANT. U-TOUCH feature brings to you a true comfort level wherever and 
whenever you want.

REMOTE CONTROL-BUTTON NAME & FUNCTIONS

"SWING" BUTTON:

 Hold the swing button (symbol 

shown above) for more than 2 seconds and the 
indoor air louver will start to swing between the 
highest and lowest limits. Once the swing button is 
released the louver will stay in the last position where 
the button was released.  
If the swing button is pushed just once the swing icon 
will appear on the remote and the louver will swing 
up and down continuously between the highest and 
lowest points. Push the swing button once more and 
the icon will disappear on the remote and the louver 
will remain at the last point the button was pushed. 
When the unit is powered off by the remote the louver 
will close on the indoor unit.
Press this button to set up the desired swing angle 
which circularly changes as below.

"U-TOUCH" BUTTON:

 Since the indoor unit is normally mounted high up on the wall or attached to the ceiling, the 

temperature at where the return air sensor is installed inside the indoor unit is higher than what it is where the 
area people stand and can feel (4 to 7 feet above the floor). If the unit uses the return air temperature as its 
target control, people may feel colder than what they really want (target) in both cooling mode and heating mode. 
The facts of air stratification and warm air rising and cold air dropping require users to set up, by experiments or 
experience, the target temperature quite few degrees higher than what you really want , in order to reach a 
satisfied or more precise indoor comfort. This is a common drawback of AC/HP units made by other manufacturers.
With YMGI's U-touch feature, this can be avoided and your comfort level can be improved.
When you press the U-TOUCH button on the remote control, the unit will use the temperature where the remote 
is located as its target temperature control. Once you do so, you will notice a figure of a person surrounded by 
stars appear on the remote. 

"SWING UP AND DOWN" BUTTON

Press this button, to set up swing angle, 
circularly changes as below:

which 

This is an universal use remote control. If remote 
control sends the following three kinds of status 
that the swing status of main unit will be:

When the guide louver start to swing up and down, if 
turn off the Swing, the air guide louver will stop at 
current position.

which indicates the guide louver swings up and 

down between that all five positions.
