Safeguarding the environment
When charging refrigerant into the system, make sure to charge in liquid state, if
the refrigerant of the appliance is R410A.Otherwise, chemical composition of
refrigerant (R410A) inside the system may change and thus affect performance
of the air conditioner.
According to the character of
pressure of the tube is very high, so be sure to be careful when you install and
repair the appliance.
refrigerant (R410A,the value of GWP is 2088), the
If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
The air conditioner must be installed by trained, qualified installers
and service mechanics.
The temperature of refrigerant circuit will be high, please keep the
interconnection cable away from the copper tube.

Safety Precautions
Symbols in this Use and Care Manual are interpreted as shown below.
Be sure not to do.
Pay attention to such a situation.
Grounding is essential.
Warning: Incorrect handling could
cause a serious hazard, such as death,
serious injury, etc.
4
Do not use the power supply circuit
breaker or pull off the plug to turn it off
during operation. This may cause a fire
due to spark, etc.
Keep the power supply circuit breaker
or plug from dirt. Connect the power
supply cord to it firmly and correctly,
lest an electric shock or a fire break out
due to insufficient contact.
Use correct power supply in
accordance with the rating plate
requirement. Otherwise, serious
faults or hazard may occur or a
fire maybe break out.
Do not knit, pull or press the power supply
cord, lest the power supply cord be broken.
An electric shock or fire is probably caused
by a broken power supply cord.
Never insert a stick or similar obstacle
to the unit. Since the fan rotates at high
speed, this may cause an injury.
Do not repair the appliance by yourself.
If this is done incorrectly, it may cause an
electric shock, etc.
Turn off the appliance by remote control
firstly before cutting off power supply if
malfunction occurs.
It is harmful to your health if the cool air
reaches you for a long time. It is advisable
to let the air flow be deflected to all the room.
Prevent the air flow from reaching the gas
burners and stove.
Do not touch the operation buttons
when your hands are wet.
Do not put any objects on the outdoor
unit.
It is the user's responsibility to make the
appliance be grounded according to
local codes or ordinances by a licenced
technician.
