FOR YOUR SAFETY USE
IN: indoor unit
OUT: outdoor unit
●
For the safety and proper use and handling of the product, please read and follow the instructions carefully.
●
The meaning of the marks below are as follows.
●
Never remodel appliance.
Use designated parts or accessories to avoid accidents.
●
In case of gas leakage, not only refill the required amount of the refrigerant gas but
also find out the gas leakage point and mend it. If the service work has to be
suspended before mending the leakage points, be sure to collect the refrigerant
gas in the outdoor unit by using pump then fasten the service ports to avoid any
further leakage. Poisonous gas may be generated when the leaked refrigerant is
exposed to fire.
●
Clean the pins of the plug and insert the plug completely into the outlet.
●
Be sure to change the cable if it is damaged.
Do not use damaged cable.
●
Do not use power supply cord extended or connected in halfway.
●
Be sure to put the units to earthing works.
●
Be sure to check the insulated resistance, more than 1M
Ω
.
Warning
※
The combinations of three LED indicators (ON/Flashing/OFF) provide the self-diagnosis information as most of them shown in
the trouble shooting guide.

●
Be sure to take off the plug when servicing.
It may cause the risk of electric shock.
●
If leakage of refrigerant occur in the installation, ventilate a room.
If the leaked refrigerant is exposed fire, poisonous gas may be generated.
Danger
●
Boosting capacitor make the control box assembly (OUT unit) high voltage.
Make the capacitor discharge enough when servicing. Otherwise will be struck
by electricity.
Improper use will cause the significant risk of death or serious injury of the user.

Please refer the marks below.
High Temperatare
Discharge electricity of the capacitor by making short circuit firstly. Then check the capacitor by tester.
Be sure to set up the tester for the measurement of bigger resistance.
