1. 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 customer. Request the cus-
tomer to keep them on hand for future use, such as for relocating or repairing the unit.
Indicates a potentially or imminently hazardous situation which,
WARNING
if not avoided, could result in death or serious injury.
Installation of this product must be done by experienced service technicians or profes-
sional 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 fi re. If the product is installed in disregard of the instructions in
this manual, it will void the manufacturer's warranty.
En-1
To avoid getting an electric shock, never touch the electrical components soon after the
[Original instructions]
power supply has been turned off. After turning off the power, always wait 10 minutes or
English
more before you touch the electrical components.
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 while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a fl ame, 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 unspecifi ed refrigerant in the refrigerant
lines. Excess pressure can cause a rupture.
If there is a refrigerant leak, make sure that it does not exceed the concentration limit.
If a refrigerant leak exceeds the concentration limit, it can lead to accidents such as
oxygen starvation.
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 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
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.
To connect the indoor unit and outdoor unit, use air conditioner piping and cables avail-
able locally as standard parts. 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.
Use a vacuum pump for R410A exclusively.
Using the same vacuum pump for different refrigerants may damage the vacuum pump
or the unit.
Use a clean gauge manifold 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 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 fi lm used as the packaging
material away from young children.
CAUTION
For the air conditioner to work appropriately, install it as written in this manual.
This product must be installed by qualifi ed personnel with a capacity certifi cation of
handling refrigerant fl uids. Refer to regulation and laws in use on installation place.
Install the product by following local codes and regulations in force at the place of instal-
lation, and the instructions provided by the manufacturer.
This product is part of a set constituting an air conditioner. The product must not be
installed alone or be installed with a device not authorized by the manufacturer.
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 product is not explosion proof, and therefore should not be installed in explosive
atmosphere.
Do not touch the fi ns of the heat exchanger. Touching the heat exchanger fi ns could
result in damage to the fi ns or personal injury such as skin rupture.
This product contains no user-serviceable parts. Always consult experienced service
technicians for repairing.
When moving or relocating the air conditioner, consult experienced service technicians
for disconnection and reinstallation of the product.
Do not place any other electrical products or household belongings under the product.
Condensation dripping from the product might get them wet, and may cause damage or
malfunction to the property.
• This product is conformed to IEC/EN61000-3-2.
• This product is designed for professional use.
• On the power supply connection, obtain the connection permission of the distribution
network operator.
• Be sure to use a dedicated power circuit.
Never use a power supply shared by another appliance.
Indicates a potentially hazardous situation that may result in
minor or moderate injury or damage to property.
