■
Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.
■
Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
■
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
■
For Sky Air or room air conditioner indoor units only:
When wiring between the BP units and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, the terminals may overheat
and electric shocks or a fire may be caused.
■
For VRV indoor units only:
When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, the terminals may overheat
and electric shocks or a fire may be caused.
■
If refrigerant gas leaks during installation work, ventilate the area
immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
■
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
■
Before touching electric terminal parts, turn off power switch.
Caution
■
Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding may cause electric shocks.
■
Gas pipe.
Ignition or explosion may occur if the gas leaks.
■
Water pipe.
Hard vinyl tubes are not effective grounds.
■
Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
■
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may cause electric
shocks and fire.
■
Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furniture get wet.
■
For Sky Air or room air conditioner indoor units only:
Install the indoor units, BP units and outdoor units, power wire
and connecting wire at least 1 meter away from televisions or
radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)
■
For VRV indoor units only:
Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)
■
Do not rinse the outdoor unit.
This may cause electric shocks or fire.
■
Do not install the air conditioner in places such as the following:
■
Where there is mist of mineral oil, oil spray or vapour for
example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
■
Where corrosive gas, such as sulfurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause the
refrigerant to leak.
■
Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
■
Where flammable gases may leak, where carbon fiber or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
■
Where the air contains high levels of salt such as that near
the ocean.
■
Where voltage fluctuates a lot, such as that in factories.
■
In vehicles or vessels.
■
Where acidic or alkaline vapour is present.
■
Do not allow a child to mount on the outdoor unit or avoid placing
any object on the unit.
Falling or tumbling may result in injury.
■
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
