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.

WARNING
To install a unit that uses R410A refrigerant, use dedicated tools and piping materials that have been manufactured specifically for R410A use. Because the pressure of
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 fire.
Tool name
Changes
Gauge manifold
The pressure in the refrigerant system is extremely
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 to use a gauge manifold with a high
pressure display range of –0.1 to 5.3 MPa and a low
pressure display range of –0.1 to 3.8 MPa.
Charging hose
To increase pressure resistance, the hose material
and base size were changed.
(The charging port thread diameter for R410A is 1/2
UNF 20 threads per inch.)
Vacuum pump
A conventional 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
–100.7 kPa (5 Torr, –755 mmHg).

• Do not bend the pipes at an angle more than 90°.
• When pipes are repeatedly bend or stretched, the material will harden, making it difficult
to bend or stretch them any more.
• Do not bend or stretch the pipes more than 3 times.
CAUTION
To prevent breaking of the pipe, avoid sharp bends.
If the pipe is bent repeatedly at the same place, it will break.

• Use pipe with water-resistant heat insulation.
CAUTION
Install heat insulation around both the gas and liquid pipes. Failure to do so may cause
water leaks.
Use heat insulation with heat resistance above 120 °C. (Reverse cycle model only)
In addition, if the humidity level at the installation location of the refrigerant piping is
expected to exceed 70%, install heat insulation around the refrigerant piping. If the
expected humidity level is 70-80%, use heat insulation that is 15 mm or thicker and if
the expected humidity exceeds 80%, use heat insulation that is 20 mm or thicker. If
heat insulation is used that is not as thick as specified, condensation may form on the
surface of the insulation.
In addition, use heat insulation with heat conductivity of 0.045W/(m·K) or less (at 20 °C).
Be sure to connect the pipe against the port on the indoor unit and the outdoor unit correctly. If the centering is improper, the flare nut cannot tightened smoothly. If the flare nut
is forced to turn, the threads will be damaged.
Do not remove the flare nut from the indoor unit pipe until immediately before connecting
the connection pipe.
Do not use mineral oil on flared part. Prevent mineral oil from getting into the system as
this would reduce the lifetime of the units.
(1) Detach the caps and plugs from the pipes.
(2) Center the pipe against the port on the indoor unit, and then turn the flare nut by hand.

low speed.
When select the “Remote controller setting”, if the detected
temperature value between the temperature sensor of the indoor
unit and the temperature sensor of the remote controller varies
significantly, it is likely to return to the control status of temperature
sensor of the indoor unit temporarily.
2 As the temperature sensor of remote controller detects the temperature near the
wall, when there is a certain difference between the room temperature and the wall
temperature, the sensor will not detect the room temperature correctly sometimes.
Especially when the outer side of the wall on which the sensor is positioned is
exposed to the open air, it is recommended to use the temperature sensor of the
indoor unit to detect the room temperature when the indoor and outdoor temperature difference is significant.
