Safety Precautions
Read these Safety Precautions carefully to ensure correct installation.
•
This manual classi
fi
es the precautions into WARNING and CAUTION.
•
Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING
CAUTION
Failure to follow any of WARNING is likely to
result in such grave consequences as death or
serious injury.
Failure to follow any of CAUTION may result in
grave consequences in some cases.
The following safety symbols are used throughout this manual:
•
Be sure to observe this instruction.
Be sure to establish an earth connection.
Never attempt.
After completing installation, test the unit to check for installation errors. Give the user adequate
•
instructions concerning the use and cleaning of the unit according to the Operation Manual.
WARNING
Installation should be left to the dealer or another professional.
•
Improper installation may cause water leakage, electrical shock, or
fi
re.
Install the air conditioner according to the instructions given in this manual.
•
Incomplete installation may cause water leakage, electrical shock, or
fi
re.
Be sure to use the supplied or speci
fi
ed installation parts.
•
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or
fi
re.
Install the air conditioner on a solid base that can support the weight of the unit.
•
An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
Electrical work should be carried out in accordance with the installation manual and the national
•
electrical wiring rules or code of practice.
Insuf
fi
cient capacity or incomplete electrical work may cause electrical shock or
fi
re.
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
•
For wiring, use a cable length enough to cover the entire distance with no connection.
•
Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power
circuit.
(Failure to do so may cause abnormal heat, electric shock or
fi
re.)
Use the speci
fi
ed types of wires for electrical connections between the indoor and outdoor units.
•
Firmly clamp the interconnecting wires so their terminals receive no external stresses.
Incomplete connections or clamping may cause terminal overheating or
fi
re.
After connecting interconnecting and supply wiring be sure to shape the cables so that they do not
•
put undue force on the electrical covers or panels.
Install covers over the wires. Incomplete cover installation may cause terminal overheating,
electrical shock, or
fi
re.
If any refrigerant has leaked out during the installation work, ventilate the room.
•
(The refrigerant produces a toxic gas if exposed to
fl
ames.)
After all installation is complete, check to make sure that no refrigerant is leaking out.
•
(The refrigerant produces a toxic gas if exposed to
fl
ames.)
When installing or relocating the system, be sure to keep the refrigerant circuit free from substances
•
other than the speci
fi
ed refrigerant (R22), such as air. (Any presence of air or other foreign
substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)
