Decide the mounting position with the customer as follows:
1. INDOOR UNIT
(1) Install the indoor unit level on a strong wall which is not subject to
vibration.
(2) The inlet and outlet ports should not be obstructed : the air should
be able to blow all over the room.
(3) Install the unit near an electric outlet or special branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit is easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the spaces shown
in (Fig. 2). Also install the unit where the filter can be removed.
2. OUTDOOR UNIT
(1) If possible, do not install the unit where it will be exposed to direct
sunlight. (If necessary, install a blind that does not interfere with
the air flow.)
(2) Do not install the unit where a strong wind blows or where it is very
dusty.
(3) Do not install the unit where people pass.
(4) Take you neighbors into consideration so that they are not disturbed
by air blowing into their windows or by noise.
(5) Provide the space shown in Fig. 2 so that the air flow is not blocked.
Also for efficient operation, leave open three of the four directions
front, rear, and both sides.
WARNING
Install at a place that can withstand the weight of the
indoor and outdoor units and install positively so that
the units will not topple or fall.
CAUTION
(1) Do not install where there is the danger of com-
bustible gas leakage.
(2) Do not install near heat sources.
(3) If children under 10 years old may approach the
unit, take preventive measures so that they can-
not reach the unit.
(4) Install the indoor unit on the wall where the height
from the floors more than 230 cm.

WARNING
(1)
The rated voltage of this product is 230 V AC 50 Hz.
(2)
Before turning on the power, check if the voltage is within
the 220 V -10 % to 240 V +10 % range.
(3)
Always use a special branch circuit and install a special
receptacle to supply power to the room air conditioner.
(4)
Use a circuit breaker and receptacle matched to the ca-
pacity of the air conditioner.
(5)
Do not extend the power cord.
(6)
Perform wiring work in accordance with standards so that
the air conditioner can be operated safely and positively.
(7)
Install a leakage circuit breaker in accordance with the
related laws and regulations and electric company
standards.
CAUTION
(1)
The power source capacity must be the sum of the air conditioner
current and the current of other electrical appliances. When the
current contracted capacity is insufficient, change the contracted
capacity.
(2)
When the voltage is low and the air conditioner is difficult to start,
contact the power company the voltage raised.

INSTALLATION MANUAL
(PART NO. 9313802028-01) AS*14/18LSBC
The basic installation work procedures are the same as conventional refrigerant (R22) models.
However, pay careful attention to the following points:
(1) Since the working pressure is 1.6 times higher than that of conventional refrigerant (R22) models,
some of the piping and installation and service tools are special.(See the table below.)
Especially, when replacing a conventional refrigerant (R22) model with a new refrigerant R410A
model, always replace the conventional piping and flare nuts with the R410A piping and flare nuts.
(2) Models that use refrigerant R410A have a different charging port thread diameter to prevent
erroneous charging with conventional refrigerant (R22) and for safety. Therefore, check
beforehand.[The charging port thread diameter for R410A is 1/2 threads per inch.]
(3) Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with refrigerant
(R22) models. Also, when storing the piping ,securely seal the opening by pinching ,taping, etc.
(4) When charging the refrigerant, take into account the slight change in the composition of the
gas and liquid phases, and always charge from the liquid phase side whose composition is
stable.
This air conditioner uses new refrigerant HFC (R410A).
Special tools for R410A
Copper pipes
It is necessary to use seamless copper pipes and it is desirable
that the amount of residual oil is less than 40 mg/10m. Do not
use copper pipes having a collapsed, deformed or discolored
portion (especially on the interior surface). Otherwise, the ex-
pansion value or capillary tube may become blocked with
contaminants.
As an air conditioner using R410A incurs pressure higher than
when using R22, it is necessary to choose adequate materials.
Thicknesses of copper pipes used with R410A are as shown in Table1.Never us copper pipes thinner than 0.8mm even
when it is available on the market.

Contents of change
Pressure is high and cannot be measured with a conventional gauge. To prevent erroneous
mixing of other refrigerants, the diameter of each port has been changed.
It is recommended the gauge with seals-0.1 to 5.3 MPa (-1 to 53 bar) for high pressure.
-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.
To increase pressure resistance, the hose material and base size were changed.
A conventional vacuum pump can be used by installing a vacuum pump adapter.
Special gas leakage detector for HFC refrigerant R410A.
Table 1 Thicknesses of Annealed Copper Pipes
(1) Do not use the existing (for R22) piping and flare nuts.
• If the existing materials are used, the pressure inside the refrigerant cycle will rise and cause breakage, injury,
etc.(Use the special R410A materials.)
(2) When installing and relocating the air conditioner, do not mix gases other than the specified refrigerant(R410A)
to enter the refrigerant cycle.
• If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an abnormally high value
and cause breakage, injury, etc.
