Safety Precautions
You should take the following safety precautions when using your air conditioner.
WARNING
INSTALLING THE
AIR CONDITIONER
• If you don’t follow the safety precautions, you may get the risk of an
electric shock, injury or death. • The manufacturer or qualified service
personnel must install this air conditioner. • Unplug the electric power
before repairing, installing or cleaning.
◆ Users should not install the air conditioner by themselves.
Ask the dealer or authorized company to install the air conditioner
except the window-type air conditioner in U.S.A and Canada.
◆ If you don’t install the air conditioner properly, it may cause a fire,
a water leakage or an electric shock.
◆ Install the indoor unit higher than 8.2ft(2.5m) from the floor to avoid the
injury caused by the operation of the fan.
(except the window-type air conditioner)
◆ The manufacturer is not responsible for the accidents or injury caused
by an incorrect installation.
◆ When installing the built-in type air conditioner, keep all electric cables
such as the power cable and the connection cord in pipes, ducts, or
cable channels to protect them from the danger of impact or any other
incidents.
POWER SUPPLY AND
CIRCUIT BREAKER
◆ If the power cord of the air conditioner is damaged, it must be replaced by
the manufacturer or a qualified person in order to avoid a hazard.
◆ The air conditioner must be plugged into an independent circuit if
applicable or connect the power cable to the auxiliary circuit breaker.
An all pole disconnection from the power supply must be
incorporated in the fixed wiring with a contact opening of 0.118 inch(3mm).
◆ Do not extend an electric cord to the air conditioner.
◆ You must install the air conditioner according to the national wiring
regulations and safety regulations.

PREPARING THE INSTALLATION
Deciding the Installation Place
You should observe the following restrictions when you decide the installation place.
General
Do NOT install the air conditioner under the following conditions;
◆ Combustible gases
◆ Saline air
◆ Machine oil
◆ Sulphide gas
◆ Special environmental conditions
If you have no alternative place to install it, first consult your dealer or a qualified person.
Indoor Unit
◆ There must be no obstacles near the air inlet and outlet.
◆ Install the indoor unit on a surface that can support its weight.
◆ Choose a place where you can easily connect the pipes and cables to the outdoor unit.
The recommended length of the pipes and cables is 24.6ft(7.5m). The maximum length is 98.4ft(30m).
◆ Leave sufficient space below the indoor unit to remove the filters easily.
◆ Maintain sufficient space around the indoor unit as seen in the picture on page 5.
◆ Make sure that the water dripping from the drain hose runs off correctly and safely.
◆ Install the indoor unit higher than 8.2ft(2.5m) from the ground.
Outdoor Unit
◆ NEVER place the outdoor unit on its side or upside down. The compressor lubricating oil may run into
the circuit and damage the outdoor unit seriously.
◆ Choose a dry and sunny place avoiding direct sunlight or strong winds.
◆ Do not obstruct the passage.
◆ Avoid a place that may disturb your neighbor. A noise may occur from the outdoor unit and the
discharged air may run into the neighborhood.
◆ Choose a place where you can easily connect the pipes and cables to the indoor unit.
The recommended length of the pipes and cables is 24.6ft(7.5m). The maximum length is 98.4ft(30m).
◆ Install the outdoor unit on a flat and stable surface.
Otherwise it may slant and make some noise and vibration.
◆ Install the outdoor unit on a hard and even place that can support its weight.
◆ Place the outdoor unit so as to let the discharged air out properly.
◆ Maintain sufficient space around the outdoor unit as seen in the picture on page 5.
◆ When you install the outdoor unit at a height, you should firmly fix it in its place.
The maximum height is 49ft(15m).
◆ Make sure that the water dripping from the drain hose runs off correctly and safely.
CAUTION
◆ The air conditioner must be installed according to the national electrical rules.
◆ Max input power & current is measured according to IEC standard and input power &
current is measured according to ISO standard.

Installing and Connecting the Drain Hose of the Indoor Unit
When installing the drain hose for the indoor unit, you should check if condensate draining is adequate.
When you pass the drain hose through the 2 169 inch(65mm) 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.
Ditch
Do NOT place the
end of the drain hose
in a hollow.
To install the drain hose, do the following.
1
If necessary, connect the 6.56ft(2m) extension drain hose to the drain hose.
2
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, and then fix the end of the
drain hose with a clamp tightly.
Shield
Drain hose
Extension drain hose
➢ If you don’t use the other drain hose hole, block it with a rubber stopper.
4
Pass the drain hose under the refrigerant pipe keeping the drain hose tight.
5
Pass the drain hose through the hole in the wall. Check if it slants
downwards as seen in the picture.
➢
The hose will be fixed permanently into position after finishing
the installation and the gas leak test;
refer to page 12 for further details.
Installing and Connecting the Drain Hose of the Outdoor Unit
While heating, ice may accumulate. During the process of defrosting,
you should check if condensate draining is adequate.
For the adequate draining, do the following.
1
Insert the drain plug into the drain hole on the underside of the outdoor unit.

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:
◆ Extended up to 98.4ft(30m)
◆ Shortened as required
☛
If you need a pipe longer than 24.6ft(7.5m):
◆
You must extend the assembly cable.
◆
You must add refrigerant to the pipes;
otherwise, the indoor unit may freeze.
1
Make sure that you prepared 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. There are some examples of correctly and
incorrectly cut edges below.

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 and heating capacity and malfunction. Refrigerant for air purging is not charged in
the outdoor unit. Use Vacuum Pump as seen in the picture.
