Be sure to comply with the local, national and international
laws and regulations.
Read "PRECAUTIONS" carefully before installation.
The following precautions include important safety items.
Observe them and never forget.
Keep this manual with the owner's manual in a handy place
for future reference.
Installation must be performed in accordance with the
requirement of NEC and CEC by authorized personnel only.
（Applicable to the North American area only）
1. PRECAUTIONS
The safety precautions listed here are divided into two categories. In
either case, important safety information is listed which must be read
carefully.
After completing the installation, make sure that the unit operates
properly during the start-up operation. Please instruct the customer
on how to operate the unit and keep it maintained.Also, inform
customers that they should store this installation manual along with
the owner's manual for future reference.
Only trained and qualified service personnel should
install, repair or service the equipment.
Improper installation, repair, and maintenance may result in
electric shocks, short-circuit, leaks, fire or other damage to
the equipment.
Failure to observe a warning may result in death.
Failure to observe a caution may result in injury or
damage to the equipment.
Install the unit according to this installation instructions
found in this document.
If installation is defective, it will cause water leakage,
electrical shock or fire.
When installing the unit in a small space, take measures
to prevent refrigerant concentration from exceeding
allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information.
Excessive refrigerant in a closed space can lead to oxygen
deficiency.
Use the attached accessories parts and specified parts
for installation.
Failure to use the included parts will cause the set to fall,
water leakage, electrical shock or fire.
Install the unit in a strong and firm location which is able
to withstand the set' s weight.
If the installation site is not secure or the installation is not
properly done, the set will drop and possibly cause injury or
damage.
The appliance should not be installed in the laundry.
Before obtaining access to terminals, all supply circuits
must be disconnected.
The appliance must be positioned so that the plug is
accessible.
The enclosure of the appliance shall be marked with
words, or with symbols, with the direction of the fluid
flow.
For electrical work, follow the local national wiring
standard, regulations and these installation instructions.
An independent circuit and single outlet must be used.
If electrical circuit capacity is insufficient or a defect exists in
the electrical work, it will cause an electrical shock or a fire.
Connect the specified cable tightly and then clamp the
cable so that no external force can act on the terminal.
If connection or fixing is not correct , it will cause a heat
build-up or fire at the connection.
Wiring routing must be properly arranged so the control
board cover is fixed properly.
If the control board cover is not fixed properly, it will cause a
heat build-up at the connection point of the terminal, which
may result in a fire or an electrical shock.
If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or similarly qualified
person in order to avoid a hazard.
An all-pole disconnection switch with a contact
separation of at least 3mm in all poles should be
connected in the fixed wiring.
When performing the piping connection, make sure that
air substances do not enter the refrigeration cycle.
If air substances enter the refrigeration cycle, it will reduce
capacity, abnormal high pressure in the refrigeration cycle,
explosion and injury.
Do not modify the length of the power supply cord or use
an extension cord, and do not share the single outlet
with other electrical appliances.
Failure to comply will cause fire or electrical shock.
Carry out the specified installation work after taking into
account strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling
and causing accidents.
CAUTION

To install properly, please read this "installation manual"
first.
The air conditioner must be installed by qualified persons.
When installing the indoor unit or its tubing, please follow
this manual closely.
If the air conditioner is installed on a metal part of the
building, it must be electrically insulated according to the
relevant standards to electrical appliances.
When all the installation work is finished, please turn on
the power only after a thorough check.
2. INSTALLATION INFORMATION
Ground the air conditioner.
Do not connect the ground wire to gas or water pipes,
lightning rod or a telephone ground wire.Incomplete
grounding may result in electric shocks.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks.
Connect the outdoor unit wires , then connect the indoor
unit wires.
You should not connect the air conditioner with the power
source until wiring and piping the air conditioner is done.
While following the instructions in this installation
manual, install drain piping in order to ensure proper
drainage and insulate piping in order to prevent
condensation.
Improper drain piping may result in water leakage and
property damage.
Install the indoor and outdoor units, power supply wiring
and connecting wires at least 3.28ft (1m) meter away
from televisions or radios in order to prevent image
interference or noise.
Depending on the radio waves, a distance of 3.28ft (1m) may
not be sufficient enough to eliminate the noise.
The appliance is not intended for use by young children
or infirm persons without supervision.
Don't install the air conditioner in the following
locations:t
Near petroleum facilities.
Near coastal areas with any concentration of salty air.
Near caustic gases, like sulfide, especially when near hot
springs.
The volt vibrates violently (in the factories).
In buses or cabinets.
In kitchens with large amounts of oil gas.
Near a strong electromagnetic wave.
Near inflammable materials or gas.
Anywhere there is acid or alkaline liquid evaporating.
Other hazardous conditions.
If the refrigerant leaks during installation, ventilate the
area immediately.
Toxic gas may be produced if the refrigerant enters into the
area and comes in contact with fire.
The temperature of refrigerant circuit is high, please keep
the interconnection cable away from the copper tube.
After completing the installation work, ensure that the
refrigerant does not leak.
Toxic gas may be produced if the refrigerant leaks into the
room and comes into contact with a source of fire, such as a
fan heater, stove or cooker.
INSTALLATION ORDER
Select the location.
Install the indoor unit.
Install the outdoor unit.
Install the connecting pipe.
Connect the drain pipe.
Connect the wiring.
Test operation.
CAUTION
The appliance must be installed in accordance with
national wiring regulations.
Do not operate your air conditioner in a wet room such
as a bathroom or laundry room.
An all-pole disconnection device which has at least 3mm
clearances in all poles, and has a leakage current that
may exceed 10mA, and a residual current device (RCD)
which has a rated residual operating current not to
exceed 30mA, and a disconnection must be incorporated
in the fixed wiring in accordance with the wiring rules.

Never throw or beat the controller.
Before installation, operate the remote controller to determine its location in a
reception range.
Keep the remote controller at least 3.28ft (1m) apart from the nearest TV set or
stereo equipment. (it is necessary to prevent image disturbances or noise
interferences.)
Do not install the remote controller in a place exposed to direct sunlight or close to a
heating source, such as a stove.
Note that the positive and negative poles are right positions when loading batteries.
