• 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 fire. 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 fire.
• If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant
is exposed to a direct flame, 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 means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
• 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.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open flames, an operating gas appliance or an operating
electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Keep any required ventilation openings clear of obstruction.
• If the power cable or the connection cable is damaged, it must be replaced by the
manufacturer, its service agent or similar qualified persons in order to avoid a safety
hazard.
• Read carefully all safety information written in this manual before you install or use the
air conditioner.
• Install the product by following local codes and regulations in force at the place of
installation, 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, ground (earth) 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 an explo-
sive atmosphere.
• To avoid getting an electric shock, never touch the electrical components soon after
the power supply has been disconnected. After disconnecting the power, always wait
5 minutes or more before you touch the electrical components.
• 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 touch the aluminum fins 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 product.
Condensation dripping from the product might get them wet, and may cause damage
or malfunction to the property.
