●Please request your sales agent or qualied technician to install your unit. Water leakage,
short circuit or re may occur if you do the installation work yourself.
●Please observe the instructions stated in the installation manual during the process of
installation. Improper installation may cause water leakage, electric shock and re.
●Make sure that the units are mounted at locations which are able to provide full support to
the weight of the units. If not, the units may collapse and impose danger.
●Observe the rules and regulations of the electrical installation and the methods described in
the installation manual when dealing with the electrical work. Use cables which are ofcially
approved in your country. Be sure to use the specied circuit. A short circuit and re may
occur due to the use of low quality wire or improper work.
●Be sure to use the specied cables for connecting the indoor and outdoor units. Please
ensure that the connections are tight after the conductors of the wire are inserted into the
terminals to prevent the external force is being applied to the connection section of the
terminal base. Improper insertion and loose contact may cause over-heating and re.
●Please use the specied components for installation work. Otherwise, the units may collapse
or water leakage, electric shock, re or stronger vibration may occur.
●Be sure to use the specied piping set for R32. Otherwise, this may result in broken copper
pipes or faults.
●When installing or transferring an air conditioner to another location, make sure that air
other than the specied refrigerant(R32) does not enter the refrigeration cycle. If other air
should enter, the pressure level of the refrigeration cycle may increase abnormally which
could result in a rupture and injury.
●Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes
into contact with re, a poisonous gas may occur.
●After completion of installation work, check to make sure that there is no refrigeration gas
leakage. If the refrigerant gas leaks into the room, coming into contact with re in the fan-
driven heater, space heater, etc., a poisonous gas may occur.
●Unauthorized modications to the air conditioner may be dangerous. If a breakdown occurs
please call a qualied air conditioner technician or electrician. Improper repairs may result
in water leakage, electric shock and re, etc.
●Be sure to connect the earth line from the power supply wire to the outdoor unit and between
the outdoor and indoor unit. Do not connect the earth line to the gas tube, water pipe, lighting
rod or the earth line of the telephone unit. Improper earthing may cause electric shocks.
●When nishing the refrigerant collection (pumping down), stop the compressor and then
remove the coolant pipe. If you remove the refrigerant pipe while the compressor is operating
and the service valve is released, air is sucked and a pressure in the freezing cycle system
will build up steeply, causing an explosion or injury.
●When installing the unit, be sure to install the refrigerant pipe before starting the compressor.
If the refrigerant pipe is not installed and the compressor is operated with the service
valve released, air is sucked and the pressure level of the refrigeration cycle may increase
abnormally which could result in a rupture and injury.
●The electric cables should neither be reworked nor added. Make sure to use an exclusive
circuit breaker. Otherwise re or electric shock might occur by connection failure, isolation
failure or over current.
●Make sure to connect cables to terminal properly and terminal cover should close rmly.
Otherwise, over heating at terminal contact, re or electric shock might occur.
●Make sure that there is no dust on any connected points of electric cables and x rmly.
Otherwise, re or electric shock might occur.
CAUTION
!
●A circuit breaker must be installed in the house distribution
box for the direct connected power supply cables to the
outdoor unit. In case of other installations a main switch
with a contact gap or more than 3mm has to be installed.
Without a circuit breaker, the danger of electric shock
exists..
●Do not install the unit near a location where
there is ammable gas. The outdoor unit may
catch re if ammable gas leaks around it.
●Please ensure smooth ow of water when installing the
drain hose. Improper installing may wet your furniture.
●An IEC approved power cord should be used. Power cord
type: NYM.
WARNING
●The unit should be mounted at stable, non-vibratory location which can provide full support to the unit.
CAUTION
●No nearby heat source and no obstruction near the air outlet is allowed.
●The clearance distances from top, right and left are specied in gure below.
●The location must be convenient for water drainage and pipe connection with the Outdoor unit.
●No nearby leakage risk of ammable gas, and no nearby source of vapor or oil smoke.
●To avoid interference from noise, please place the unit and its remote controller at least 1m from the radio and television.
●To avoid any error in signal transmission from the remote controller, please put the controller far away from high-frequency
machines and high-power wireless systems.
●The installation height should be at least 2300 mm or more from the oor.
●The distance from the air outlet to the re alarm must be at least 1500mm and there must be no re alarm in the front
direction of the indoor unit.

!CAUTION
● Remove burr and jagged edge will cause leakage.
● Point the side to be trimmed downwards during trimming to prevent copper
chips from entering the pipe.
● Before aring, please put on the are nut.
Gas Leakage Inspection
Please use gas leakage detector to check if
leakage occurs at the connection of Flare nut
as shown on the right.
If gas leakage occurs, further tighten the
connection to stop leakage.
!CAUTION
● In case of removing are nut of a indoor unit, rst remove a nut of small diameter
side, or a seal cap of big diameter side will y out. Free from water into the piping
when working.
● Be sure to tighten the are nut to the specied torque with a torque wrench.If the
are nut is overtightened, the nut may be split after a long period has passed,
and may cause a refrigerant leak.
!WARNING
!CAUTION
Be sure that the drain hose is not loosely connected or bend or
improper conditions like above gures.
!CAUTION
You are free to choose the side (left or right) for the installation of drain hose.
Please ensure the smooth ow of condensed water of the Indoor unit during
installation. (Carelessness may result in water leakage.)

INSTALLATION OF REFRIGERATING PIPES AND AIR REMOVAL
CONNECTION OF POWER CORDFINAL STAGE OF INSTALLATION
INSTALLATION AFTER CONNECTION OF REFRIGERATING PIPES
● The refrigerating pipe should be adjusted to t into the hole on the wall and then
ready for further connection.
● The terminals of 2 connected pipes must be covered with insulator used for terminal
connection. Then the pipes are wrapped with insulatin pipe.
● Connect the connecting cord after removing low cover. (Refer to “CONNECTION
OF POWER CORD”)
● After adjustment, t the connecting cord and pipes into the space available under
the unit. Use holder to hold them tight.
● Be sure to cut the extra binding band. (Otherwise, it may result in abnormal noise or
dewfall.)
Installation
Hang the Indoor unit onto the hanger. Use the temporary stand at
the back of the Indoor unit to push its lower part 15cm forwards.
● Place the drain hose through the hole on the wall.
● Wrap the refrigerating pipes with insulation pipe after
connecting refrigerating pipe.
● Connect the connecting cord after removing low cover. (Refer
to “Connection of Power Cord”)
● After adjustment, the connecting cord and refrigerating pipes
are placed into the space available under the Indoor unit.
● The projection of Indoor unit must hook to the mounting plate.
Pull this to the
front during the
connection of
refrigerating pipes
to ease task.

Wiring of The Indoor Unit
● For wire connection of the Indoor unit, you need to remove
the front cover, the low cover under the body of the unit and
terminal cover.
● Remove the cover from the terminal base and screw the
cable.
● The connected terminals should be completed sealed with heat insulator
and then tied up with rubber strap.
● Do not tie the terminals with the tape too tight.
If any clearance or over-tightening may cause condensation.
● Please tie the pipe and power line together with vinyl tape as shown in
the gure showing the installation of Indoor and Outdoor units.
● To enhance the heat insulation and to prevent water condensation,
please cover the outdoor part of the drain hose and pipe with insulation
pipe.
● Completely seal any gap with putty.
