• Please mount the Outdoor unit of stable ground to prevent vibration and increase
of
noise
level.
Decide the location for piping after sorting out the different types of pipe available.
• When removing side cover, please pull the handle after undoing the hook by pulling
it downward. Reinstall the side cover in the reverse order of the removal.
CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
• There is holes on the base of Outdoor unit for condensed water to exhaust.
• In order to flow condensed water to the drain, the unit is installed on a stand or a
block so that the unit is 100mm above the ground as shown figure. Join the drain
pipe to one hole.
• Cover the drain hole with a bush. To install the bush, put it on the drain hole as
shown in the figure and press the both sides of the bush to fit into the hole.
After installation, check whether the drain pipe and bush cling to the base firmly.
• Install the outdoor unit horizontally and make sure that condensate drains away.
• In case of using in chilly area
Especially, in case that there are many snows by very cold in chilly area, condensed
water freezes on the base and may result not to drain. In this case, please remove
the bush and the drain pipe at the bottom of unit. (Left and center near discharge
portion of air, each 1 place). It becomes smooth drain.
Ensure that the distance from the drain hole to the ground is 250 mm or more.
OUTDOOR UNIT
CAUTION
• Do not touch the suction
port, bottom surface, or
aluminum fin of the outdoor
unit.
Failure to do so may cause
an injury.
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 flaring, please put on the flare nut.

CAUTION
• In case of removing flare nut of a indoor unit, first remove
a nut of small diameter side, or a seal cap of big diameter
side will fly out. Free from water into the piping when
working.
• Be sure to tighten the flare nut to the specified torque with
a torque wrench.
If the flare nut is overtightened, the nut may be split after a
long period has passed, and may cause a refrigerant leak.
• Please be careful when bending the copper pipe.
• Screw in manually while adjusting the center. After that, use a torque wrench to
tighten the connection.

Remove of Air From The Pipe And Gas Leakage Inspection
AIR REMOVAL
Procedures of using Vacuum Pump for Air Removal
As shown in right figure, remove the cap
of valve core. Then, connect the charge
hose. Remove the cap of valve head.
Connect the vacuum pump adapter to the
vacuum pump and connect the charge
hose to the adapter.
1
Fully tighter the "Hi" shuttle of the manifold
valve and completely unscrew the "Lo"
shuttle. Run the vacuum pump for about
10-15 minutes, then completely tighten the
"Lo" shuttle and switch off the vacuum
pump.
• Loosen the spindle of the service valve
with small diameter by 1/4 turn and
tighten the spindle immediately after 5
to 6 seconds.
• Remove the charging hose from the
service valve.
2
Completely unscrew the spindle of the
service valve (at 2 places) in anticlockwise
direction to allow the flow of refrigerant
(using Hexagonal Wrench key).
3
Tighten the cap of valve head. Check the
cap's periphery if there is any gas leakage.
The task is then completed.
4
Gas leakage inspection
Please use gas leakage detector to check if leakage
occurs at connection of Flare nut as shown on the
right.
If gas leakage occurs, further tighten the connection
to stop leakage.

Preparation of Pipe
• Use a pipe cutter to cut the copper pipe and remove burr.
CONNECTION OF POWER CORD
WARNING
•
If you cannot attach the side plate due to the connection cord, please
press the connecting cord in the direction to the front panel to fix it.
•
Be sure that the hooks of the side cover fixed in certainly. Otherwise water
leakage may occur and this causes short circuit or faults.
•
The connecting cord should not touch to service valve and pipes. (it
becomes high temperature in heating operation.)
Wiring of the Outdoor Unit
• Please remove the side cover for wire connection.
Checking for the electric source and the voltage range
• Before installation, the power source must be checked and necessary wiring work must
be completed. To make the wiring capacity proper, use the wire gauge list below for the
wiring from house distribution fuse box to the outdoor unit in consideration of the blocked
rotor current.

• Investigate the power supply capacity and other
electrical conditions at the installing location.
Depending on the model of room air conditioner to be
installed, request the customer to make arrangements
for the necessary electrical work etc.
The electrical work includes the wiring work up the
outdoor unit. In localities where electrical conditions
are poor, use of a voltage regulation is recommended.
• Install outdoor for the room air conditioner within the
reaching range of the line cord.

Wiring of The Indoor Unit
• For wire connection of the Indoor unit, you need to remove the front cover
under the body of the unit and terminal cover.
, the low cover
• Remove the cover from the terminal base and screw the cable.
WARNING
• The naked part of the wire core should be 10mm fix it to the terminal tightly. Then
try to pull the individual wire to check if the contact is tight. Improper insertion may
burn the terminal.
• Be sure to use only wire specified for the use of air-conditioner.
• Please refer to the manual for wire connection and the wiring technique should
meet the standard of the electrical installation.
• There is an AC voltage drop between the LN terminal if the power is on. Therefore,
be sure to remove the plug from its socket.
WARNING
• Leave some space in the connecting cord for maintenance
purpose and be sure to secure it with the cord band.
• Secure the connecting cord along the coated part of the wire
using the cord band. Do not exert pressure on the wire as this
may cause overheating or fire.
WARNING
• THIS APPLIANCE MUST BE
EARTHED.

WARNING
• Never remodel the power plug nor extend the long-distance
cord.
• Keep additional length for the power cord and do not render
the plug under external force as this may cause poor contact.
• Do not fix the power cord with U-shape nail.
• The power cable easily generates heat. Do not bring the
cable together with a wire or vinyl tie.
Operation test
• Please ensure that the air conditioner is in normal operating
condition during the operation test.
• Explain to your customer the proper operation procedures as
described in the user' s manual.
• If the indoor unit won't operate, check the cable for correct
connection.
• Turn on the lamp in the room where the indoor unit is installed
and check the remote controller for normal operation.
2
Installation of Remote Controller
• The remote controller can be placed in its holder which is fixed
on wall or beam.
• To operate the remote controller at its holder, please ensure that
the unit can receive signal transmitted from the controller at the
place where the holder is to be fixed. The unit will beep when
signal is received from the remote controller. The signal
transmission is weaken by the fluorescent light. Therefore, during
the installation of the remote control holder, please switch on
the light, even during day time, to determine the mounting location
of the holder.
The controller must be hooked onto the hook at the lower part
of the holder. Push in the remote controller in the direction as
shown in figure below.
Force-cooling operation
• When the service switch
of the outdoor unit is
pressed for 1 or more
seconds, the force-
cooling operation starts.
Use this mode when
performing the failure
diagnosis or collecting
refrigerant into the
outdoor unit.
CAUTION
• Do not operate the unit for more than 5 minutes
while the spindle of the service valve is closed.
