not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that may result in minor or
moderate injury or damage to property.
WARNING
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..
Installation of this product must be done by experienced service technicians or
professional installers only in accordance with this manual. Installation by non-
professional or improper installation of the product might cause serious accidents such
as injury, water leakage, electric shock, or fi re. If the product is installed in disregard of
the instructions in this manual, it will void the manufacturer’s warranty.
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 an electric shock or
a fi re.
If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant is
exposed to a direct fl ame, it may produce 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 unspecifi ed refrigerant in the refrigerant
lines. Excess pressure can cause a rupture.
During installation, make sure that the refrigerant pipe is attached fi rmly 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 or relocating the air conditioner, do not mix gases other than the
specifi ed 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.
For appropriate working of the air conditioner, install it as written in this manual.
To connect indoor unit and outdoor unit, or indoor unit and branch box, use air
conditioner piping and cables available through your local distributor. This manual
describes proper connections using such installation set.
Do not modify power cable, use extension cable or branch wiring. Improper use may
cause electric shock or fi re by poor connection, insuffi cient insulation or over current.
Do not purge the air with refrigerants but use a vacuum pump to vacuum the
installation.
There is no extra refrigerant in the outdoor unit for air purging.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
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.
Do not modify this unit, such as opening a hole in the cabinet.
WARNING
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.
Children should be monitored to ensure they do not play with the device.
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

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 nec-
essary to choose adequate materials.
Thicknesses of copper pipes used with R410A are as shown in the table below. Never use
copper pipes thinner than 0.8 mm even when it is available on the market.
Thicknesses of Annealed Copper Pipes
Nominal diameter (in.) Outer diameter (mm) Thickness (mm)
1/4 6.35 0.80
3/8 9.52 0.80
WARNING
To install a unit that uses R410A refrigerant, use dedicated tools and piping materials
that have been manufactured specifi cally 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 fi re.
Do not use a vacuum pump or refrigerant recovery tools with a series motor, since it
may ignite.
2.2. Power
WARNING
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.
Install a leakage circuit breaker in accordance with the related laws and regulations and
electric company standards.
The circuit breaker is installed in the permanent wiring. Always use a circuit that can trip
all the poles of the wiring and has an isolation distance of at least 3 mm between the
contacts of each pole.
CAUTION
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
insuffi cient, change the contracted capacity.
When the voltage is low and the air conditioner is diffi cult to start, contact the power
company the voltage raised.

6. OUTDOOR UNIT INSTALLATION
Switch cover
Hook
Screw
• Set the unit on a strong stand, such as one made of
concrete blocks to minimize shock and vibration.
• Do not set the unit directly on the ground because it will
cause trouble.
Switch cover removal
(1) Remove the screw.
(2) Push downward the cover.
Installing the switch cover
After inserting the hook of Switch cover, then push upward,
and then tighten the tapping screw.
WARNING
• Install the unit where it will not be tilted by more than 5°.

securely.
Air purge
Always use a vacuum pump to purge the air.
Refrigerant for purging the air is not charged in the outdoor unit at the factory.
Close the high pressure side valve of the gauge manifold fully and do not operate it during
the following work.
CAUTION
• Refrigerant must not be discharged into atmosphere.
• After connecting the piping, check the joints for gas leakage with gas leak detector.
(1) Check if the piping connections are secure.
(2) Check that the stems of 2-way valve and 3-way valve are closed fully.
(3) Connect the gauge manifold charge hose to the charging port of the 3-way valve
(side with the projection for pushing in the valve core).
(4) Open the low pressure side valve of the gauge manifold fully.
(5) Operate the vacuum pump and start pump down.
(6) Slowly loosen the fl are nut of the 3-way valve and check if air enters, then retighten
the fl are nut.
(When the fl are nut is loosened the operating sound of the vacuum pump changes
and the reading of the compound pressure gauge goes from minus to zero.)
(7) Pump down the system for at least 15 minutes, then check if the compound pressure
gauge reads -0.1 MPa (-76 cmHg, -1 bar).
(8) At the end of pump down, close the low pressure side gauge of the gauge manifold
fully and stop the vacuum pump.
(9) Slowly loosen the valve stem of the 3-way valve. When the compound pressure
gauge reading reaches 0.1-0.2 MPa, retighten the valve stem and disconnect the
charge hose from the 3-way valve charging port.
(If the stem of the 3-way valve is opened fully before the charge hose is
disconnected, it may be diffi cult to disconnect the charge hose.)
