When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get
a partner to help, and bend your knees when lifting to reduce strain on
your back. Sharp edges or thin aluminum fins on the air conditioner can
cut your fingers.
When Installing...
...In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit's weight. It
may be necessary to construct a strong wood or metal frame to provide
added support.
...In a Room
Properly insulate any tubing run inside a room to prevent "sweating" that
can cause dripping and water damage to walls and floors.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level
foundation for the outdoor unit. This prevents water damage and abnor-
mal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Pro-
vide a suitable air baffle.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting
snow. Provide snow vents.
When Connecting Refrigerant Tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare and
union tubes before connecting them, then tighten the nut with a torque
wrench for a leak-free connection.
• Check carefully for leaks before opening the refrigerant valves.
NOTE:
Depending on the system type, liquid and gas lines may be either narrow
or wide. Therefore, to avoid confusion the refrigerant tubing for your par-
ticular model is specified as either "small" or "large" rather than as "liquid"
or "gas".
When Servicing
• Turn the power OFF at the main circuit breaker panel before opening
the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal
scraps or bits of wiring have been left inside the unit being serviced.
• After installation, explain correct operation to the customer, using the
operating manual.

SAFETY PRECAUTIONS
Be sure to read this manual carefully before installation.
The warnings and precautions indicated in this manual contain
important information pertaining to your safety. Be sure to observe
them.
Hand this manual, together with the operating manual, to the cus-
tomer. Request the customer to keep them on hand for future use,
such as for relocating or repairing the unit.
ENGLISH
Installation of this product must be done by experienced service tech-
nicians or professional installers only in accordance with this manual.
Installation by nonprofessional or improper installation of the product
may cause serious accidents such as injury, water leakage, electric shock,
or fire. If the product is installed in disregard of the instructions in this
manual, it will void the manufacturer's warranty.
To avoid getting an electric shock, never touch the electrical components
soon after the power supply has been turned off. After turning off the
power, always wait 10 minutes or more before you touch the electrical
components.
Do not turn ON the power until all work has been completed. Turning ON
the power before the work is completed can cause serious accidents such
as electric shock or fire.
If refrigerant leaks while work is being carried out, ventilate the area. If the
refrigerant comes in contact with a flame, it produces a toxic gas.
Installation must be performed in accordance with regulations, codes, or
standards for electrical wiring and equipment in each country, region, or
the installation place.
Do not use this equipment with air or any other unspecified refrigerant in
the refrigerant lines.
Excess pressure can cause a rupture.
During installation, make sure that the refrigerant pipe is attached firmly
before you run the compressor. Do not operate the compressor under the
condition of refrigerant piping not attached properly with 2-way or 3-way
valve open. This may cause abnormal pressure in the refrigeration cycle
that leads to rupture and even injury.
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 rupture, injury, etc.
To connect the indoor unit and outdoor unit, use air conditioner piping
and cables available locally as standard parts. This manual describes prop-
er connections using such installation set.
If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Do not modify power cable, use extension cable or branch wiring. Improp-
er use may cause electric shock or fire by poor connection, insufficient
insulation or over current.
Do not purge the air with refrigerants but use a vacuum pump to vacuum
the installation.
There is not extra refrigerant in the outdoor unit for air purging.
Using the same vacuum pump for different refrigerants may damage the
vacuum pump or the unit.
Use a clean gauge manifold, vacuum pump and charging hose for R410A
exclusively.
During the pump-down operation, make sure that the compressor is
turned off before you remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation
with 2 way or 3 way valve open. This may cause abnormal pressure in the
refrigeration cycle that leads to rupture and even injury.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the
appliance.
To avoid danger of suffocation, keep the plastic bag or thin film used as
the packaging material away from young children.
Read carefully all safety information written in this manual before you in-
stall or use the air conditioner.
This unit must be installed by qualified personnel with a capacity certifi-
cate for handling refrigerant fluids. Refer to regulation and laws in use on
installation place.

ABOUT THIS PRODUCT
PRECAUTIONS FOR USING R410A REFRIGERANT
The basic installation work procedures are the same as conventional refrig-
erant (R22) models.
However, pay careful attention to the following points:
Since the working pressure is 1.6 times higher than that of conventional re-
frigerant (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.
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 diam-
eter for R410A is 1/2-20 UNF.]
Be more careful that foreign matter (oil, water, etc.) does not enter the pip-
ing than with refrigerant (R22) models. Also, when storing the piping, se-
curely seal the opening by pinching, taping, etc.
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 where refrigerant composition is stable.

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/10 m. Do not use copper pipes having a collapsed,
deformed or discolored portion (especially on the interior surface). Otherwise,
the expansion 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
use copper pipes thinner than 0.8 mm even when it is available on the market.

CAUTION
To install a unit that uses R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifically for R410A use. Because
the pressure of R410A refrigerant is approximately 1.6 times higher than
R22, failure to use dedicated piping material or improper installation can
cause rupture or injury. Furthermore, it can cause serious accidents such as
water leakage, electric shock, or fire.
POWER
The rated voltage of this product is 208/230 V AC
60 Hz.
Before turning on the power, check if the voltage is
within the 208 V -10 % to 230 V +10% range.
Always use a special branch circuit and install a
special receptacle to supply power to the room air
conditioner.
Use a circuit breaker and receptacle matched to the
capacity of the air conditioner.
Do not extend the power cord.
WARNING
Perform wiring work in accordance with standards
so that the air conditioner can be operated safely
and positively.
Install a leakage circuit breaker in accordance
with the related laws and regulations and electric
CAUTION
company standards.
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.
When the voltage is low and the air conditioner is
difficult to start, contact the power company the
voltage raised.
