1.2. Special precautions
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected
and checked.
• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate
earthing (grounding) can cause accidental injury or death.
• Earth (Ground) the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and
a possible re hazard.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to
help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin
aluminum ns on the air conditioner can cut your ngers.
When Installing...
...In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary
to construct a strong wood or metal frame to provide added support
.
...In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that can cause drip-
ping and water damage to walls and oors.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the
outdoor unit. This prevents water damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame.
Provide a suitable air bafe.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow.
When Connecting Refrigerant Tubing
• Keep all tubing runs as short as possible.
• Use the are method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the are and union tubes before
connecting them, then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before opening the refrigerant valves.
NOTE:
Depending on the syste m type, liquid and gas lines may be ei ther narrow or wide.
Therefore, to avoid confusion the refrigerant tubing for your particular model is specied
as either “small” or “large” rather than as “liquid” or “gas”.
When Servicing
• Turn the power OFF at the main circuit breaker panel before opening the unit to check
or repair electrical parts and wiring.
• Keep your ngers and clothing away from any moving parts.
• Clean up the site after you nish, remembering to check that no metal scraps or bits of
wiring have been left inside the unit being serviced.
• After installation, explain correct operation to the customer, using the operating manual.
WARNING
Indicates a potentially or imminently hazardous situation which, if
not avoided, could result in death or serious injury.
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 10 minutes or
more before you touch the electrical components.
Installation of this product must be done by experienced service technicians or
professional installers only in accordance with this manual. Installation by nonprofessional or improper installation of the product may cause serious accidents such
as injury, water leakage, electric shock, or re.
If the outdoor unit is installed in disregard of the instructions in the installation 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 electric shock or re.
If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant is
exposed to a direct ame, it may produce a toxic gas.
Installation work must be performed in accordance with regulations, codes, or standards
for electrical wiring and equipment in each country, region, or the installing place.
Do not use this equipment with air or any other unspecied refrigerant in the refrigerant
lines. Excess pressure can cause a rupture.
During installation, make sure that the refrigerant pipe is attached rmly before you run
the compressor. Do not operate the compressor under the condition of refrigerant piping
not attached properly with 3-way valve open. This may cause abnormal pressure in the
refrigeration cycle that leads to rupture and even injury.

En-3
WARNING
• 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. (See
the table below.)
Especially, when replacing a conventional refrigerant (R22) model with a new
refrigerant R410A model, always replace the conventional piping and are nuts with
the R410A piping and are nuts.
• 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
1/2-20 UNF.]
• Be careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant models. Also, when storing the piping, securely seal the openings by
pinching, taping, etc.
• 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 where
refrigerant composition is stable.
2.2. Special tools for R410A refrigerant
WARNING
To install a unit that uses R410A refrigerant, use dedicated tools and piping materials
that have been manufactured specically for R410A use. Because the pressure of
R410A refrigerant is approximately 1.6 times higher than R22, failure to use dedicated
piping material or improper installation can cause rupture or injury. Furthermore, it can
cause serious accidents such as water leakage, electric shock, or re.
Tool name Changes
Gauge manifold Pressure is high and cannot be measured with a conventional
gauge. To prevent erroneous mixing of other refrigerants, the
diameter of each port has been changed.
It is recommended the gauge with seals –0.1 to 5.3 MPa (-1 to
53 bar) for high pressure. –0.1 to 3.8 MPa (-1 to 38 bar) for low
pressure.
Charging hose To increase pressure resistance, the hose material and base
size were changed.
Vacuum pump A conventional vacuum pump can be used by installing a
vacuum pump adapter.
Gas leakage detector Special gas leakage detector for HFC refrigerant R410A.
Copper pipes
It is necessary to use seamless copper pipes and it is desirable that the amount of residual
oil is less than 40 mg/33ft (10m). Do not use copper pipes having a collapsed, deformed
or discolored portion (especially on the interior surface). Otherwise, the expansion valve
or capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using conventional
refrigerant, it is necessary to choose adequate materials.
Thicknesses of copper pipes used with R410A are as shown in the table. Never use
copper pipes thinner than that in the table even when it is available on the market.

2. ABOUT THIS PRODUCT
2.1. Precautions for using R410A refrigerant
WARNING
Do not introduce any substance other than the prescribed refrigerant into the
refrigeration cycle. If air enters the refrigeration cycle, the pressure in the refrigeration
cycle will become abnormally high and cause the piping to rupture.
If there is a refrigerant leak, make sure that it does not exceed the concentration limit.
If a refrigerant leak exceeds the concentration limit, it can lead to accidents such as
oxygen starvation.
Do not touch refrigerant that has leaked from the refrigerant pipe connections or other
areas. Touching the refrigerant directly can cause frostbite.
If a refrigerant leak occurs during operation, immediately vacate the premises and
thoroughly ventilate the area. If the refrigerant comes in contact with a ame, it produces
a toxic gas.
The basic installation work procedures are the same as conventional refrigerant models.
