• 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.
• Devices disconnected from the power supply should
be completely disconnected in the condition of
overvoltage category.
CAUTION
• 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
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.
• 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 "Step 2.4 Optional:Extending the
power cable" in the installation manual.
