Safety Precautions
The precautions described herein are classi
fi
ed as WARNING and CAUTION. They both contain important
•
information regarding safety. Be sure to observe all precautions without fail.
Meaning of WARNING and CAUTION notices
•
WARNING ....Failure to follow these instructions properly may result in personal injury or loss of life.
CAUTION ..... Failure to observe these instructions properly may result in property damage or personal injury, which
may be serious depending on the circumstances.
The safety marks shown in this manual have the following meanings:
•
Be sure to follow the instructions.
Be sure to establish an earth connection.
Never attempt.
After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate
•
the air conditioner and take care of it with the aid of the operation manual.
WARNING
Ask your dealer or quali
fi
ed personnel to carry out installation work.
•
Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or
fi
re.
Install the air conditioner in accordance with the instructions in this installation manual.
•
Improper installation may result in water leakage, electric shocks or
fi
re.
Be sure to use only the speci
fi
ed accessories and parts for installation work.
•
Failure to use the speci
fi
ed parts may result in the unit falling, water leakage, electric shocks or
fi
re.
Install the air conditioner on a foundation strong enough to withstand the weight of the unit. In addition, the water
•
heater should be securely mounted in a location that can bear its weight when it is completely
fi
lled with water.
A foundation of insuf
fi
cient strength may result in the equipment falling and causing injury.
Electrical work must be performed in accordance with relevant local and national regulations and with instructions
•
in this installation manual. Be sure to use a dedicated power supply circuit only. In addition, check that the power
sources for the outdoor unit and water heater’s electric equipment are separated.
Insuf
fi
ciency of power circuit capacity and improper workmanship may result in electric shocks or
fi
re.
Use a cable of suitable length.
•
Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or
fi
re.
Make sure that all wiring is secured, the speci
fi
ed wires are used, and that there is no strain on the terminal connections or wires.
•
Improper connections or securing of wires may result in abnormal heat build-up or
fi
re.
When wiring the power supply and connecting the wire between the indoor unit or water heater and outdoor unit,
•
position the wires so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric shocks,
fi
re or over heating terminals.
• If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant comes into contact with
fi
re.
• After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of
fi
re, such as a fan heater, stove or cooker.
When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and
•
use only the speci
fi
ed refrigerant (R410A).
The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.
During installation, attach the refrigerant piping securely before running the compressor.
•
If the compressor is not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in
the refrigeration cycle, which may result in equipment damage and even injury.
During pump-down, stop the compressor before removing the refrigerant piping.
•
If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed,
causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
Do not install the product in places with excessive moisture.
•
The installation of the product in places with excessive moisture, such as bath room, may result in electric shocks or
fi
re.
• Check the supply temperature of hot water with
fi
nger tips
fi
rst at the time of using the shower or taking bath.
Be sure to check the temperature of hot water at the time of supplying hot water or taking a bath so that you may scald yourself.
• Do not touch the water mixing taps at the time of supplying hot water.
You may scald yourself with the hot water by doing so.
Only water from the municipal supply should be used in this system.
•
Failure to use municipal water may result in malfunction or water leakage.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.
Be sure to install an earth leakage breaker.
•
Failure to install an earth leakage breaker may result in electric shocks or
fi
re.
