Do not place the outdoor unit near the handrail of the balcony.
•
Children may climb onto the outdoor unit, lean over the handrail and fall over.
Use only a speci
fi
ed power cable. Poor connection, poor insulation, and exceeding the allowable current will lead
•
to electric shock and
fi
re.
Attach the connecting cables securely to the terminal. Or secure it
fi
rmly with a "wiring suppressor".
•
Loose connection will lead to malfunction, electric shock, and
fi
re.
Install a breaker (earth leakage breaker) to cut off all AC main current at the same time.
•
If you do not install a breaker (earth leakage breaker), it may cause electric shock and
fi
re.
Be sure to install the refrigerant pipe before operating the compressor. If the refrigerant pipe is not installed and
•
you operate the compressor while the valve is open, air will be sucked into the system and abnormal pressure
will occur in the cooling cycle. This will damage the unit and cause injuries.
During the pump-down operation, make sure that the compressor is turned off before you remove the refrigerant
•
piping. Do not remove the connection pipe while the compressor is in operation with 2-way or 3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even injury.
CAUTION!
This mark indicates procedures which, if improperly performed, might possibly result in personal
harm to the user, or damage to property.
Obtain the distrib
•
ution network operator's agreement about the power capacity of the power supply system,
speci
fi
cation of the cable and the harmonic current, and etc. when you connect the outdoor unit with the power
supply.
This unit must be connected to a power supply with impedance of 0.33 ohm and below. If the power supply does
•
not satisfy this requirement, please consult the power supplier.
This product is intended for professional use.
•
Be sure to use a dedicated power circuit.
Never use a power supply shared by another appliance.
Do not install the unit in the following areas:
•
Area with
•
high salt content, such as at the seaside.
It will deteriorate metal parts, causing the parts to fall or the unit to leak water.
Area
fi
lled with mineral oil or containing a large amount of splashed oil or steam, such as a kitchen.
•
It will deteriorate plastic parts, causing the parts to fall or the unit to leak water.
Area that generates substances that adversely affect the equipment, such as sulfuric gas, chlorine gas, acid,
•
or alkali.
It will cause the copper pipes and brazed joints to corrode, which can cause refrigerant leakage.
Area containing equipment that generates electromagnetic interference.
•
It will cause the control system to malfunction, preventing the unit from operating normally.
Area that can cause combustible gas to leak, contains suspended carbon
fi
bers or
fl
ammable dust, or volatile
•
in
fl
ammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a
fi
re.
Avoid installing th
•
e unit at places where it will come into contact with animals’ urine or ammonia.
Do not use the unit for special purposes, such as storing food, raising animals, growing plants, or preserving
•
precision devices or art objects. It can degrade the quality of the preserved or stored objects.
Ground the unit. Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or a telephone ground
•
wire. Improper grounding may cause electric shock.
Perform draining for the unit according to the Installation manual. Check that the water is properly drained.
•
If the drain processing is improperly installed, water may drip down from the unit, wetting the furniture.
Do not touch the
fi
ns with bare hands.
•
Be sure not to start or stop the operation of air conditioning with power breaker. Otherwise, it may cause malfunc-
•
tion or water leakage.
When setting it up near the equipment that generates electromagnetic waves and the equipment that generates
•
the higher harmonics wave, be sure to take measures against noise. Otherwise, it may cause malfunction or
failure.
When energizing to the crankcase heater, please turn on the power 12 hours or earlier before operation begins.
•
When the energizing time is short, it may cause failure. Besides, please do not turn off power during the busy
season.
