Test operation
If the refrigerant leaks during installation, ventilate the area
immediately. Toxic gas may be produced if the refrigerant
comes into contact with fire.
The temperature of the refrigerant circuit will be high, so keep
the interconnection cable away from the copper tube.
After completing installation, check that the refrigerant does
not leak. Toxic gas may be produced if the refrigerant leaks
into the room and comes into contact with a source of fire,
such as a fan heater, stove, or cooker.
Ground the air conditioner. Do not connect the ground wire to
gas or water pipes, a lightning rod, or a telephone ground wire.
Inappropriate grounding may result in electrical shock.
Be sure to install an earth leakage breaker. Failure to install an
earth leakage breaker may result in electrical shock.
Connect the outdoor unit wires, then connect the indoor unit
wires. Do not connect the air conditioner with the power supply
until the wiring and piping are done.
Install drain piping to ensure proper drainage and insulate the
piping to prevent condensation. Improper drain piping may
result in water leakage and property damage.
The indoor and outdoor units, power supply wiring, and
connecting wires should be at least 1 m away from televisions
or radios to prevent image interference or noise. Depending on
the radio waves, a distance of 1 m may not be sufficient to
eliminate the noise.
The appliance is not intended for use by young children or
infirm persons without supervision.
Do not install the air conditioner in the following circumstances
or locations:
The appliance must be installed in accordance with national
wiring regulations.
Do not operate the air conditioner in a wet room, such as a
bathroom or laundry room.
An all-pole disconnection device must have at least 3 mm (0.1
in) clearances in all poles and a leakage current that may
exceed 10 mA. The residual current device (RCD) must have a
rated residual operating current not exceeding 30 mA.
Disconnection must be incorporated in the fixed wiring in
accordance with wiring rules.
CAUTION
When petrolatum is in the area
When the surrounding air is salty (near the coast)
When caustic gas (such as sulfide) is in the air (near a hot
spring)
When the volt vibrates violently (in factories)
In buses or cabinets
In a kitchen full of oil or gas
When there are strong electromagnetic waves in the air
When there are inflammable materials or gas nearby
When acid or alkaline liquid is evaporating
When other special conditions exist
To install properly, please read this installation manual
first.
The air conditioner must be installed by qualified persons.
When installing the indoor unit or its tubing, please follow
this manual as strictly as possible.
If the air conditioner is installed on a metal part of a
building, it must be electrically insulated according to the
standards relevant to electrical appliances.
When all installation work is finished, turn on the power
only after a thorough check.
Regretfully, there will be no further announcement of any
change to this manual resulting from product improvement.
