• 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.
Please face this side (suction side)
of the unit to the wall.

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.
• After installation, check whether the drain pipe clings 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.

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.
Power Source And Operation Test
Power Source
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.
After completing the service switch
operation, be sure to keep the
switch pressed for one or more
seconds and stop the force-cooling
operation.

Preparation of Pipe
• Use a pipe cutter to cut the copper pipe and remove burr.
• 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
• Do not touch the suction
por t, bottom surface, or
aluminum fin of the outdoor
unit.
Failure to do so may cause

• 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.

WARNING
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.)
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.
How to Attach the Front Cover
