turned off. Electrical shock may occur. After turning off the power, always wait 10
minutes or more before touching electrical components.
Request your dealer or a professional installer to install this unit in accordance with
this Installation Manual. An improperly installed unit can cause serious accidents
such as water leakage, electric shock, or fi re. If this 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
fi re.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a fl ame, it produces a toxic gas.
Installation must be performed in accordance with the requirement of NEC (National
Electrical Code) and CEC (Canadian Electrical Code) by authorized personnel only.
During installation, make sure that the refrigerant pipe is attached fi 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 breakage and even injury.
When installing and relocating the air conditioner, do not mix gases other than the
specifi 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 breakage, injury, etc.
Be sure to always use the parts accessories or the specifi ed parts for installation.
Failure to use the specifi ed parts may cause the equipment to fail, water leakage,
electric shock or fi re.
Install the equipment in a location that is out of reach of children.
Be sure to check that there are no refrigerant leaks after installation is completed.
If there is refrigerant gas leak indoors and comes into contact with an open fl ame
from such sources as a fan heater, bunsen burner, or stove, it can generate toxic
fumes.
Do not turn OFF the breaker (or the disconnect switch) connected to the RB unit during operations except in an emergency. Doing so may cause a compressor malfunction. When turning OFF the RB unit power, fi rst stop refrigerant system operations,
and then turn OFF the breaker (or disconnect switch) connected to the RB unit.
CAUTION
Read carefully all security information before use or install the air conditioner.
Do not attempt to install the air conditioner or a part of the air conditioner by yourself.
This unit must be installed by qualifi ed personnel with a capacity certifi cate for han-
dling refrigerant fl uids. Refer to regulation and laws in use on installation place.

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 leakage, make sure that it does not exceed the concentration limit.
If a refrigerant leakage 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 area. Touching the refrigerant directly can cause frostbite.
If a refrigerant leakage occurs during operation, immediately vacate the premises
and thoroughly ventilate the area.
If the refrigerant comes in contact with a fl ame, it produces a toxic gas.
2.2. Special tools for R410A
WARNING
To install a unit that uses the R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifi cally for R410A use.
Because the pressure of the R410A refrigerant is approximately 1.6 times higher
than the 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 fi re.
Tool name Contents of change
Gauge manifold
Pressure is huge and cannot be measured with a conventional
(R22) gauge. To prevent erroneous mixing of other refrigerants,
the diameter of each port has been changed.
It is recommended to use a gauge manifold with a high
pressure display range 30in Hg to 768 psi (–0.1 to 5.3 MPa)
and a low pressure display range 30in Hg to 551 psi (–0.1 to
3.8 MPa).
Charging hose
To increase pressure resistance, the hose material and base
size were changed.
Vacuum pump
A conventional (R22) vacuum pump can be used by installing
a vacuum pump adapter. Be sure that the pump oil does not
back flow into the system. Use one capable for vacuum suction
of 5 Torr, –755 mm Hg (–100.7 kPa).
Gas leakage
detector
Special gas leakage detector for HFC refrigerant R410A.
2.3. Accessories
Do not discard the accessories required for installation until the installation work is
complete.
