CAUTION
New refrigerant air conditioner installation
• This air conditioner adopts the new HFC refrigerant
(R410A) which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb
1.6 times higher than that of refrigerant R22. Accompanied with
the new refrigerant, refrigerating oil has also been changed.
Therefore, do not let water, dust, former refrigerant, or
refrigerating oil enter the refrigerating cycle during installation
work.
• To prevent charging an incorrect refrigerant and refrigerating
main unit and installation tools are changed from those for the
conventional refrigerant.
• Accordingly the exclusive tools are required for the new
refrigerant (R410A).
• For connecting pipes, use new and clean piping designed for
R410A, and please care so that water or dust does not enter.
To disconnect the appliance from main power supply.
• This appliance must be connected to the main power supply
by means of a switch with a contact separation of at least
0.1" (3 mm).
The installation fuse (all types can be used) must be used for
the power supply line of this conditioner.

3Selection of installation place
• Install the air conditioner at enough strong place to withstand the weight of the unit.
If the strength is not enough, the unit may fall down resulting in injury.
• Install the air conditioner at a height 8'2" (2.5 m) or more from the oor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous
because you may contact with revolving fan or active electricity.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
• Place where drained water will not cause any problem.

• Place where organic solvent is used nearby.
• Place close to a machine generating high frequency.
• Place where the discharged air blows directly into the window of the neighbor house. (Outdoor unit)
• Place where noise of the outdoor unit is easily transmitted.
(When install the outdoor unit on the boundary with the neighbor, pay due attention to the level of noise.)
• Place with poor ventilation. (Before air ducting work, check whether value of air volume, static pressure and duct
resistance are correct.)
• Do not use the air conditioner for special purposes such as preserving food, precision instruments, or art objects,
or where breeding animals or growing plants are kept. (This may degrade the quality of preserved materials.)
• Place where any of high-frequency appliances (including inverter devices, private power generators, medical

Incomplete grounding cause an electric shock.
Do not connect earth wires to gas pipes, water pipes, lightning conductor or telephone earth wires.
• Appliance shall be installed in accordance with national wiring regulations.

and remote controller. The wires indicated by the broken lines or dot-and-dash lines are provided at the locally.
2. Refer to the both indoor and outdoor unit wiring diagrams.
3. The power of the indoor unit is supplied from the outdoor unit.
* Use 2-core shield wire (MVVS AWG 20 to AWG 16) for the remote controller wiring in the
simultaneous twin simultaneous triple and simultaneous double twin systems to prevent noise problems.
Connect both ends of the shield wire to earth leads.
* Connect earth wires for each indoor unit in the simultaneous twin, simultaneous triple and simultaneous double
twin systems.
The remote controller wire and system interconnection wires cannot be parallel to contact each other and
cannot be stored in the same conduits. If doing so, a trouble may be caused on the control system due to
noise or other factor.
WARNING

Otherwise, the system will fail.
• Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires
during peeling them.
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
The coating may melt resulting in an accident.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.
