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.
 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.

shock or fire.
 Use the unit on a single outlet
circuit. Do not share the power
outlet with other appliances.
Obtain the consent by a
qualified installer before
connecting the unit to the
power supply system.
 This indicates the possibility of serious injury or damage to environments when
operated incorrectly.
 Check the unit for damage
that may have taken place
during transportation and do
not install or use damaged

If necessary, bend the pipe to fit along the bottom of the indoor unit.
Then pull it out through the appropriate hole.
 The pipe should not project from the rear of the indoor unit.
 The bending radius should be 4 inch(100mm) or more.
6
Pass the pipe through the hole in the wall.

Cutting or Extending the Pipe
A 24.6ft (7.5m) pipe is supplied with the air conditioner. (optional)
The length of the pipe can be:
Model
 Extended up to “A”
 Shortened as required
 If you need a pipe longer than 24.6ft (7.5m):
 You must extend the assembly cable.
 For further details on how much refrigerant(R410A) should be
added, refer to Page 13.
1
Make sure that you have the required tools (pipe cutter, reamer, flaring tool
and pipe holder.)
2
If you want to shorten the pipe, cut it using a pipe cutter, ensuring that the cut
edge remains at 90° with the side of the pipe (see examples of correctly and
incorrectly cut edges below.)

When installing the drain hose for the indoor unit, check if condensation draining is adequate.
When passing the drain hose through the 65-mm hole drilled in the wall, check the following:
2inch
(50mm)
less
The hose must
NOT slant upwards.
The end of the drain
hose must NOT be
placed under water.
Do NOT bend the hose
in different directions.
Keep a clearance of
at least 2inch (50mm)
between the end of the
hose and the ground.

Do NOT place the end
of the drain hose in a
hollow.

If you use the extension drain hose, insulate the inside of the extension drain
hose with a shield.
3
Fit the drain hose into 1 of 2 drain hose holes, then fix the end of the drain
hose tightly with a clamp.

Purging the Connected Pipes
The outdoor unit is loaded with sufficient R410A refrigerant for a 24.6ft (7.5m)
pipe You should purge the air in the indoor unit and in the pipe.
If air remains in the refrigerant pipes, it affects the compressor. It may cause
reduction of cooling capacity and malfunction.
Refrigerant for air purging is not charged in the outdoor unit.
Use Vacuum Pump as seen in the picture.

Open the valve of the low pressure side of manifold gauge counterclockwise.
5
Purge the air in the connected pipes using the vacuum pump for about
10 minutes.
- Close the valve of the low pressure side of manifold gauge clockwise.
- Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about
10 minutes.
This procedure is very important to avoid a gas leak.
- Turn off the vacuum pump.
- Remove the hose of the low pressure side of manifold gauge.

Set a valve cork of liquid and gas service port to the open position.
7
Mount the valve stem nuts and the service port cap to the valve, and tighten
them at the torque of 13.2ft•lb (183kgf•cm) with a torque wrench.

COMPLETING THE INSTALLATION
ENGLISH
Fixing the Indoor Unit in Place
After checking for gas leaks in the system, insulate the pipe, hose and cables.
Then place the indoor unit on the installation plate.
1
To avoid condensation problems, place heat-resistant polyethylene foam
separately around each refrigerant pipe in the lower part of the indoor unit.
2
Wrap the refrigerant pipe and the drain hose in the rear of the indoor unit with
the absorbent pad.
 Wind the pipe and hose three times to the end of the indoor unit with the
absorbent pad. (0.79 inch(20mm) interval)
3
Wind the pipe, assembly cable and drain hose with insulation tape.
4
Place the bundle (the pipe, assembly cable and drain hose) in the lower part of
the indoor unit carefully so it doesn’t project from the rear of the indoor unit.
Installation plate
5
Hook the indoor unit to the installation plate and move the unit to the right
and left until it is securely in place.
6
Wrap the rest of the pipe with vinyl tape.
7
