Safeguarding the environment
Note
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 the performance
of the air conditioner.
According to the character of
pressure of the tube is very high, so be careful when you install and repair the
appliance.
refrigerant (R410A,the value of GWP is 1975), 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 a professional engineer.
The temperature of refrigerant circuit will be high, please keep the
interconnection cable away from the copper tube.

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.
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

Protection
Features of protector
The protective device will work at following cases.
Restarting the unit at once after operation stops or changing mode during operation, you need to
wait 3 minutes.
Connect to power supply and turn on the unit at once, it may start 20 seconds later.
If the air conditioner runs in COOLING or DRY mode with
door or window opened for a long time when relative
humidity is above 80%,dew may drip down from the outlet.

.
If strong interference(from excessive static
electricity discharge, power supply voltage
abnormality)presents, operation will be
abnormal. At this time, disconnect from the
power supply and connect back 2-3 seconds later.
Changing mode during operation, 3 minutes
will delay.
This odor may come from another source
such as furniture, cigarette etc, which is
sucked in the unit and blows out with the air.
Caused by the flow of refrigerant in the
air conditioner, not a trouble.
Defrosting sound in heating mode.
The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.
Mist appears when the room air becomes
very cold because of cool air discharged
from indoor unit during COOLING or DRY
operation mode.

After connecting piping as required, install the drain hose. Then connect the power cords. After connecting,
wrap the piping, cords and drain hose together with thermal insulation materials.

Installation instructions
Piping Joints Thermal Insulation:
Wrap the piping joints with thermal
insulation materials and then wrap
with a vinyl tape.
Piping Thermal Insulation:
a. Place the drain hose under the piping.
b. Insulation material uses polythene foam over 6mm in thickness.
Note: Drain hose is prepared by user.
Drain pipe should point downward for easy drain flow.
Do not arrange the drain pipe twisted, sticking out or wave
around, do not immerse the end of it in water.
If an extension drain hose is connected to the drain pipe, make
sure to thermal insulated when passing along the indoor unit.
