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.
However, pay careful attention to the following points:
1. SAFETY PRECAUTIONS
• Be sure to read this manual carefully before installation.
• The warnings and precautions indicated in this manual contain important information
pertaining to your safety. Be sure to observe them.

unit.
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
non-professional or improper installation of the product may cause serious accidents
such as injury, water leakage, electric shock, or îš¿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
îš¿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 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 unspeciîš¿ed refrigerant in the refrigerant
lines. Excess pressure can cause a rupture.
During installation, make sure that the refrigerant pipe is attached îš¿rmly before you
run the compressor. Do not operate the compressor under the condition of refrigerant
piping not attached properly with 2-way or 3-way valve open. This may cause abnormal
pressure in the refrigeration cycle that leads to rupture and even injury.
When installing or relocating the air conditioner, do not mix gases other than the
speciîš¿ed refrigerant (R410A) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to
an abnormally high value and cause rupture, injury, etc.
For the air conditioner to work appropriately, install it as written in this manual.
To connect the indoor unit and outdoor unit, use air conditioner piping and cables
available locally as standard parts. This manual describes proper connections using
such installation set.

or regional standards.
*3 Select the breaker that enough load current can pass through it.
• Before starting work check that power is not being supplied to all poles of the indoor
unit and outdoor unit.
• Install all electrical works in accordance to standard.
• Install the disconnect device with a contact gap of at least 3mm in all poles nearby the
units. (Both indoor unit and outdoor unit)
• Wiring size must comply with the applicable local and national code.
3.2. Selecting the pipe material
CAUTION
Do not use existing pipes.
Use pipes that have clean external and internal sides without any contamination which
may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.
It is necessary to use seamless copper pipes.
Material: Phosphor deoxidized seamless copper pipes.
It is desirable that the amount of residual oil is less than 40 mg/10 m.
Do not use copper pipes that have a collapsed, deformed, or discolored portion
(especially on the interior surface). Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.
Improper pipe selection will degrade performance. 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 those indicated in the table even if they are available
on the market.
Thicknesses of Annealed Copper Pipes (R410A)
Pipe outside diameter
[mm (in.)] Thickness [mm]
6.35 (1/4)
0.89.52 (3/8)
12.70 (1/2)
15.88 (5/8) 1.0
19.05 (3/4) 1.2
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 speciîš¿cally 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 îš¿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/10 m. 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.
2.3. Accessories
WARNING
For installation purposes, be sure to use the parts supplied by the manufacturer or other
prescribed parts. The use of non-prescribed parts can cause serious accidents such as
the unit falling, water leakage, electric shock, or îš¿re.
Following installation parts are supplied. Use them as required.
Keep this manual in a safe place, and do not discard any other accessories until the
installation work has been completed.
