1. SAFETY PRECAUTIONS
• Read carefully all of safety information written in this manual before you install or use
the air conditioner.
• 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 customer. Request the cus-
tomer to keep them on hand for future use, such as for relocating or repairing the unit.
WARNING
Indicates a potentially or imminently hazardous situation
which, if 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
• The appliance, outlet and inlet shall be installed, operated and stored in a room with a
fl oor area larger than X m2.

• 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 profes-
sional 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 be-
fore the work is completed can cause serious accidents such as electric shock or 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 refriger-
ant 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 abnor-
mal 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 speci-
fi ed refrigerant (R32) 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 condi-
tioner 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.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open fl ames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Using the same vacuum pump for diff erent refrigerants may damage the vacuum
pump or the unit.
• Use a clean gauge manifold, vacuum pump and charging hose for R32 or R410A
exclusively.
• Do not modify this unit, such as opening a hole in the cabinet.
• 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.
CAUTION
• Read carefully all safety information written in this manual before you install or use
the air conditioner.
• This unit must be installed by qualifi ed personnel with a capacity certifi cation of han-
dling refrigerant fl uids. Refer to regulation and laws in use on installation place.
• Install the unit by following local codes and regulations in force at the place of instal-
lation, and the instructions provided by the manufacturer.
• This unit is part of a set constituting an air conditioner. The unit must not be installed
alone or be installed with non-authorized device by the manufacturer.
• When installing pipes shorter than 3 m, sound of the outdoor unit will be transferred
to the indoor unit, which will cause large operating sound or some abnormal sound.
• Always use a separate power supply line protected by a circuit breaker operating on
all wires with a distance between contact of 3 mm for this product.
• To protect the persons, earth (ground) the product correctly, and use the power cable
combined with an Earth Leakage Circuit Breaker (ELCB).
• This units are not explosion proof, and therefore should not be installed in explosive
atmosphere.
• This unit contains no user-serviceable parts. Always consult experienced service
technicians for repairing.
• When moving or relocating the air conditioner, consult experienced service techni-
cians for disconnection and reinstallation of the unit.
• 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, un-
less 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.
• Do not touch the aluminum fi ns of heat exchanger built-in the indoor or outdoor unit
to avoid personal injury when you install or maintain the unit.
• Do not place any other electrical products or household belongings under the indoor
unit or outdoor unit. Condensation dripping from the unit might get them wet, and
may cause damage or malfunction to the property.
• Be careful not to scratch the air conditioner when handling it.
• After installation, explain correct operation to the customer, using the operating manual.
Precautions for using R32 refrigerant
The basic installation work procedures are the same as conventional refrigerant (R410A,
R22) models. However, pay careful attention to the following points:
WARNING
Since the working pressure is 1.6 times higher than that of refrigerant R22 models,
some of the piping and installation and service tools are special. (See “2.1. Special
tools for R32 (R410A)”.)
Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model,
always replace the conventional piping and fl are nuts with the R410A piping and R32 and
fl are nuts on the outdoor unit side.
For R32 and R410A, the same fl are nut on the outdoor unit side and pipe can be used.
