1. SAFETY PRECAUTIONS

• Be sure to read this Manual thoroughly before installation.
• The warnings and precautions indicated in this Manual contain important information
pertaining to your safety. Be sure to observe them.
• Hand this Manual, together with the Operating Manual, to the customer. Request the
customer to keep them on hand for future use, such as for relocating or repairing the
unit.
Indicates a potentially or imminently hazardous situation
WARNING
which, if not avoided, could result in death or serious injury.
Indicates a potentially hazardous situation that may result in
CAUTION
minor or moderate injury or damage to property.
• Installation of this product must be done by experienced service technicians or profes-
sional installers only in accordance with this manual. Installation by non-professional
or improper installation of the product might cause serious accidents such as injury,
water leakage, electric shock, or fi re. If the product is installed in disregard of the
instructions in this manual, it will void the manufacturer's warranty.
• Do not turn on the power until all work has been completed. Turning on the power
before the work is completed can cause serious accidents such as an electric shock
or a fi re.
• If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant
is exposed to a direct fl ame, it may produce a toxic gas.
• Installation must be performed in accordance with regulations, codes, or standards for
electrical wiring and equipment in each country, region, or the installaton place.
• Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open fl ames, an operating gas appliance or an operating
electric heater.
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Read carefully all of safety information written in this manual before you install or use
the air conditioner.
• Install the unit by following local codes and regulations in force at the place of installa-
tion, and the instructions provided by the manufacturer.
• This unit is part of a set constituting an air conditioner. The unit must not be installed
alone or be installed with non-authorized device by the manufacturer.
• Always use a separate power supply line protected by a circuit breaker operating on all
wires with a distance between contact of 3 mm for this unit.
• To protect the persons, earth (ground) the unit correctly, and use the power cable
combined with an Earth Leakage Circuit Breaker (ELCB).
• The units are not explosion proof, and therefore should not be installed in explosive
atmosphere.
• To avoid getting an electric shock, never touch the electrical components soon after
the power supply has been turned off. After turning off the power, always wait 5 min-
utes or more before you touch the electrical components.
• This unit contains no user-serviceable parts. Always consult experienced service
technicians for repairing.
For authorized service personnel only.

• When moving or relocating the air conditioner, consult experienced service technicians
for disconnection and reinstallation of the unit.
• Do not place any other electrical products or household belongings under indoor unit
or outdoor unit. Condensation dripping from the unit might get them wet, and may
cause damage or malfunction of your property.
• Be careful not to scratch the air conditioner when handling it.
• After installation, explain correct operation to the customer, using the operating manual.
Precautions for using R32 refrigerant
The basic installation work procedures are the same as conventional refrigerant (R410A,
R22) models.
However, pay careful attention to the following points:
Since the working pressure is 1.6 times higher than that of refrigerant R22 models,
some of the piping and installation and service tools are special. (See "2.1. Special
tools for R32 (R410A)".)
Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model,
always replace the conventional piping and fl are nuts with the R32 and R410A piping and
fl are nuts on the outdoor unit side.
For R32 and R410A, the same fl are nut on the outdoor unit side and pipe can be used.
Models that use refrigerant R32 and R410A have a different charging port thread diam-
eter to prevent erroneous charging with refrigerant R22 and for safety. Therefore, check
beforehand. [The charging port thread diameter for R32 and R410A is 1/2-20 UNF.]
Be more careful than R22 so that foreign matter (oil, water, etc.) does not enter the
piping. Also, when storing the piping ,securely seal the opening by pinching, taping, etc.
(Handling of R32 is similar to R410A.)
1-Installation (Space)
• That the installation of pipe-work shall be kept to a minimum.
• That pipe-work shall be protected from physical damage.
• That compliance with national gas regulations shall be observed.
• That mechanical connections shall be accessible for maintenance purposes.
• In cases that require mechanical ventilation, ventilation openings shall be kept clear
of obstruction.
• When disposing of the product is used, be based on national regulations, properly
processed.
2-Servicing
2-1 Service personnel
• Any person who is involved with working on or breaking into a refrigerant circuit
should hold a current valid certifi cate from an industry-accredited assessment
authority, which authorises their competence to handle refrigerants safely in accor-
dance with an industry recognised assessment specifi cation.
• Servicing shall only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel shall be
carried out under the supervision of the person competent in the use of fl ammable
refrigerants.
• Servicing shall be performed only as recommended by the manufacturer.
