Safety precautions
Power supply line, fuse or circuit breaker
Always make sure that the power supply is compliant with current safety standards. Always install the air conditioner in
compliance with current local safety standards.
Always verify that a suitable grounding connection is available.
Verify that the voltage and frequency of the power supply comply with the specifications and that the installed power is
sufficient to ensure the operation of any other domestic appliance connected to the same electric lines.
Always verify that the cut-off and protection switches are suitably dimensioned.
Verify that the air conditioner is connected to the power supply in accordance with the instructions provided in the
wiring diagram included in the manual.
Always verify that electric connections (cable entry, section of leads, protections...) are compliant with the electric
specifications and with the instructions provided in the wiring scheme. Always verify that all connections comply with
the standards applicable to the installation of air conditioners.
Be sure not to perform power cable modification, extension wiring, and multiple wire connection.
- It may cause electric shock or fire due to poor connection, poor insulation, or current limit override.
- When extension wiring is required due to power line damage, refer to "How to connect your extended power cables" in
the installation manual.
• Make sure that you earth the cables.
- Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire. If earthing is not
CAUTION
complete, electric shock or fire may occur.
• Install the circuit breaker.
- If the circuit breaker is not installed, electric shock or fire may occur.
• Make sure that the condensed water dripping from the drain hose runs out properly and safely.
• Install the power cable and communication cable of the indoor and outdoor unit at least 1m away from the
electric appliance.
• Install the indoor unit away from lighting apparatus using the ballast.
- If you use the wireless remote controller, reception error may occur due to the ballast of the lighting
apparatus.
• Do not install the air conditioner in following places.
- Place where there is mineral oil or arsenic acid. Resin parts flame and the accessories may drop or water
may leak. The capacity of the heat exchanger may reduce or the air conditioner may be out of order.
- The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet. The
copper pipe or connection pipe may corrode and refrigerant may leak.
- The place where there is a machine that generates electromagnetic waves. The air conditioner may not
operate normally due to control system.
- The place where there is a danger of existing combustible gas, carbon fiber or flammable dust. The place
where thinner or gasoline is handled. Gas may leak and it may cause fire.
• Make sure that the air inlet and outlet of the air conditioner is not partially or entirely blocked by surrounding
object.
• Select a stable place with firm surface to install the product in level and make sure to fix it firmly to prevent it
from vibrating. (Avoid place with unstable surface since the air conditioner may generate noise.)
• Try to maintain the length of the pipe connection within allowed distance.
• Do not install the indoor and outdoor unit in a place where corrosive gas, such as sulfur oxides, ammonia and
sulphurous fumes, exists. (Copper pipe and braze part may corrode and cause gas leakage.)
• Use supplied installation parts.
• Do not install the outdoor unit at an unstable places such as rooftop. If installation is unavoidable, make sure
that you fix the unit firmly. Avoid places where strong wind or storm can possibly knock down the product
(such as sea shore or place with frequent storm).
