SAFETY PRECAUTION
●
Read the safety precautions carefully before operating the unit.
●
The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
WARNING ........ Incorrect methods of installation may cause death or serious injury.
CAUTION ......... Improper installation may result in serious consequence.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper way of

!
!
This air conditioner uses new refrigerant HFC (R410A)
The basic installation work procedures are the same as conventional refrigerant (R22) models.
However, pay careful attention to the following points:
(1) Since the working pressure is 1.6 times higher than that of conventional refrigerant (R22) models, some of the piping and installation and service
tools are special.
Especially, when replacing a conventional refrigerant (R22) model with a new refrigerant R410A model, always replace the conventional piping
and
fl
are nuts with the R410A piping and
fl
are nuts.
(2) Models that use refrigerant R410A have a different charging port thread diameter to prevent erroneous charging with conventional refrigerant (R22)
and for safety. Therefore, check beforehand. [The charging port thread diameter for R410A is 1/2 UNF 20 threads per inch.]
(3) Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with refrigerant (R410A) models. Also, when storing the piping, securely seal the
openings by pinching, taping, etc.
(4) When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the
liquid phase side whose composition is stable.
●
Please request your s
ales ag
ent or quali
fi
ed technician to install your unit. Water leakage, short circuit or
fi
re may occur if you do the installation
work yourself.
●
Please observe the instructions stated in the installation manual during the process of installation. Improper installation may cause water leakage,
electric shock and
fi
re.
●
Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the units may collapse
and impose danger.
●
Observe the rules and regulations of the electrical installation and the methods described in the installation manual when dealing with the electrical
work. Use power cables approved by the authorities of your country.
●
Be sure to use the speci
fi
ed wire for connecting the indoor and outdoor units. Please ensure that the connections are tight after the conductors of
the wire are inserted into the terminals. Improper insertion and loose contact may cause over-heating and
fi
re.
●
Please use the speci
fi
ed components for installation work. Otherwise, the units may collapse or water leakage, electric shock and
fi
re may occur.
●
Be sure to use the speci
fi
ed piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
●
When installing or removing an air conditioner, only speci
fi
ed refrigerant (R410A) shall be allowed, do not allow air or moisture to remain in the
refrigeration cycle. Otherwise, pressure in the refrigeration cycle may become abnormally high so that a rupture may be caused.
●
Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with
fi
re, a poisonous gas may occur.
●
After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks into the room, coming
into contact with
fi
re in the fan-driven heater, space heater, etc., a poisonous gas may occur.
●
Unauthorized modi
fi
cations to the air conditioner may be dangerous. If a breakdown occurs please call a quali
fi
ed air conditioner technician or
electrician. Improper repairs may result in water leakage, electric shock and
fi
re, etc.
WARNING
CAUTION
●
A circuit breaker or fuse (16A time delay) must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
A main switch with a contact gap of more than 3mm has to be installed in the power supply line to the outdoor unit.
●
Do not install the unit near a location where there is
fl
ammable gas. The outdoor unit may catch
fi
re if
fl
ammable gas leaks around it.
●
Please ensure smooth
fl
ow of water when installing the drain hose.
●
Piping shall be suitable supported with a maximum spacing of 1m between the supports.
