Safety Precautions
Keep this installation manual together with the user’s manual in a handy place so that you can find it whenever
you need to see it after reading this manual thoroughly.
 Make sure to read the following safety precautions carefully before installation.
 Make sure to observe the cautions specified in this manual.
 Conduct a test run of the unit after installation and then explain all system functions to the owner.
 The indications and meanings are as shown below.
WARNING
 This indicates the possibility of serious injury or death.

Installation must be carried
out by a qualified installer.

Installers are required to read
the general information
carefully for safety.

Do not put the unit near
dangerous substances to
prevent fire, explosion or
injury and do not expose
the unit to direct sunlight.
Do not install the unit by
yourself (owners).
Incorrect installation of the
unit could cause injury due
to fire, electric shock and
water leakage or from the
unit falling. Consult a dealer
or a qualified installer.
Install the unit in a place
where it is strong enough
to hold the product weight.
When installed in place
where it is not strong
enough to withhold the
product weight, the unit
could fall and cause injury.
The units must be installed
according to distances
declared, in order to permit
accessibility from each side,
either to guarantee correct
operation of maintenance
or repairing products. The
unit’s parts must be reach-
able and removable com-
pletely under safety condi-
tion (for people or things)

Use the specified wires to
connect the indoor and
outdoor units securely and
attach the wires firmly to the
terminal block connecting
sections so that the pressure
is not applied to the sections.
Inappropriate connection and
fixing could cause fire.

Avoid the use of an
extension cord and do not
share the power outlet with
other appliances. Incomplete
connection, defective
insulation or exceeding the
permissible current may cause
electric shock or fire.

Make sure that the refrigerant
gas does not leak after
completing the installation.
If the refrigerant gas of
the indoor unit leaks and
comes into contact with the
fan heater, space heater or
stove, harmful substances
will be generated.
Perform the installation
securely referring to
the installation manual.
Incomplete installation
could cause personal injury
due to fire, electric shock
and water leakage or from
the unit falling.
Attach the electrical cover
to the indoor and outdoor
unit securely. If not, it could
result in fire or electric
shock due to dust or water.
Make sure to use the part
provided or specified parts
for the installation work.
The use of defective parts
could cause an injury or
leakage of water due to a
fire, an electric shock, the
unit falling, etc.
Make sure to turn off
the main power when
setting up the indoor unit
electrical circuit or power
cords.
There is a risk of electric
shock.

be recovered and disposed
of in an appropriate way by
qualified personnel. At the
end of the life cycle, take it to
a proper recycling or disposal
center or return it to the
dealer so that it can be
disposed correctly.
Grounding the unit.
Do not connect the ground
to a gas pipe, water pipe,
lightning rod or telephone
grounding. Defective
grounding could cause
electric shock.

Do not install the unit in a
place where it is exposed to
inflammable gas leakage.
There is a risk of explosion.

Install a ground leakage
breaker depending on the
installation place (where it is
humid). If not, it may cause
electric shock.

Perform the drainage/piping
work securely according to
the installation manual.
If not, water could drop from
the unit and household
goods could get wet and
damaged.
Fasten a flare nut with a
torque wrench as specified
in this installation manual.
When fastened too tight,
a flare nut may break after
a long period of time and
cause refrigerant leakage.

To prevent injury when
accidentally touching the
indoor unit fan, install the
indoor unit on a place higher
than 2.5m.

The air conditioner must be
installed according to the
national electrical
regulations.

The maximum input power &
current is measured
according to the IEC standard
and the input power &
current is measured
according to the ISO and
EN14511standard.
WARNING
 This indicates the possibility of serious injury or death.

The unit should be installed in
accordance with the National
Electrical regulations.

Ensure that the national safety
code requirements have been
followed for the main supply
circuit. Ensure that a properly
sized and connected ground
wire is in place.

Check if the voltage and the
frequency of the main power
supply are those required for
the unit to be installed and
check the connection.

Make sure that properly sized
disconnecting and safety
switches are installed.
Do not attempt to repair,
move, modify or reinstall
the unit on your own. Make
sure that these installations
are carried out by qualified
personnel to avoid electric

ENGLISH
Choosing the Installation Location
 Avoid the following places to prevent malfunction of the unit
- Where there is machine oil - Salty environment such as the seaside areas
- Where sulfide gas exists - Other special atmosphere areas
CAUTION
 Where airflow is not blocked
 Where cool air can be distributed throughout the room
 Install the refrigerant piping length and the height
difference of both indoor and outdoor units as
indicated in the installation diagram
 Wall that prevents vibration and is strong enough to hold the product weight
 Out of the direct sunlight
 1m or more away from the TV or radio
(to prevent the screen from being distorted or noise from being generated)
 As far away as possible from fluorescent and incandescent lights (so that the remote
control can be operated well)
 A place where the air filter can be replaced easily
PREPARING FOR INSTALLATION
Observe the clearances and maximum lengths as seen in the picture below when installing the air conditioner.
125 mm
or more

Fixing the Installation Plate
Purging the Indoor Unit
Upon delivery, there may be inert gas inside the indoor unit. Purge the gas
from the indoor unit before connecting the assembly pipe.
Unscrew the caps at the end of each pipe.
Result: All inert gas exhausts from the indoor unit.

To prevent dirt or foreign substances from getting into the pipes during
installation, do NOT remove the caps completely until you are ready to
connect the pipes.
INSTALLING THE AIR CONDTIONER
Before fixing the installation plate to the wall or window frame, you must
determine the position of the 65mm hole through which the cable, pipe and
hose pass to connect the indoor unit to the outdoor unit.
When facing the wall, the pipe and cable can be connected from the:
 Right
 Left
 Underside (right)
 Rear (right or left)
1
Determine the position of the pipe and drain hose hole as seen in the picture
and drill the hole with an inner diameter of 65mm so that it slants slightly
downwards.
2If you fix the indoor unit to a... Follow step(s)...
Wall 3.
Window frame 4 to 6.
3
Fix the installation plate to the wall giving attention to the weight of the
indoor unit.
 If you mount the plate to a concrete wall with anchor bolts, the anchor
bolts must not project more than 20mm.
4
Determine the positions of the wooden uprights to be attached to the
window frame.
5
Attach the wooden uprights to the window frame giving attention to the
weight of the indoor unit.
6
Attach the installation plate to the wooden uprights using tapping screws as
seen in the picture.

INSTALLING THE AIR CONDTIONER
EEV Kit Installation
Connection of refrigerant piping & Insulation
1Insert bot anchors, use existing ceiling supports or construct
a suitable support.
CAUTION
Ensure the ceiling is strong enough to support the
weight of the indoor unit. Before hanging the unit,
test the strength of each attached suspension bolt.
2Connect the “IN” refrigerant pipe to the outdoor unit.
3Connect the “OUT” refrigerant pipe to each indoor unit(A, B and C).
The liquid and gas pipes should not be crossed when piping connection.
4Insulate the connection piping. A joint part of pipe needs double
thickness of insulation.
5The EEV kit has to be installed that the user has no access to it. (built-in type)
