• Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there is a danger
of frostbite.
• Carry out drain piping properly following this installation manual and insulate the pipe to prevent
condensation.
Improper drain piping may result in indoor water leakage and property damage.
• Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions
or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)
• Install the indoor unit as far as possible from fluorescent lamps.
If a wireless kit is installed in a room where the electronic lighting type (inverter or rapid start types)
fluorescent lamps exist, the transmitting distance of a remote controller may be shorter.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).
Plastic parts may deteriorate and cause parts to fall off or water to leak.
2. Where corrosive gas, such as sulphurous acid gas, is produced.
Corrosion of copper pipes or brazed parts may occur and cause refrigerant leakage.
3. Where there is a machine that generates electromagnetic wave and where voltage fluctuation often
occurs such as a factory.
Control system may malfunction and as a result the unit may not properly operate.
4. Where flammable gas may leak, where carbon fibre or ignitable dust is suspending in the air, or where
volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
• The air conditioner is not intended for use in a potentially explosive atmosphere.

5. REFRIGERANT PIPING WORK
〈For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit.〉
〈Make sure to carry out thermal insulation in both gas and liquid piping. Incomplete insulation may
result in water leakage. Thermal resistance of the insulation for gas piping must be 120°C or higher.
In a high humidity environment, strengthen the refrigerant piping insulation. If insulation is
insufficient, condensation may form on the insulation surface.
Be sure to check that the refrigerant is R410A before starting the job. (If a different refrigerant is used,
a normal operation cannot be carried out.)〉
This product is a dedicated model for new refrigerant (R410A). At installation, make sure to observe the
following precaution.
• For flare connection, use dedicated pipe cutter and flaring tools for R410A.
• Apply ester oil or ether oil to the inside of the flare section before connecting.
• Use the flare nuts provided with the unit. Do not use a class 1 flare nut.
Otherwise the refrigerant may leak.
• To prevent dust, moisture or other foreign matters from getting into the tube, either pinch the tube end or
cover the end with tape.
Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such
•
as air, etc. If any refrigerant gas leaks while working on the unit, ventilate the room thoroughly right
away.

• The refrigerant piping can be taken out from the following side of
the unit.
Left side, Right side, Back side, Bottom side
You must decide from which side you intend to take out the
refrigerant piping.
• Be sure to use both a spanner and a torque wrench together as
shown in the drawing, when connecting or disconnecting pipes
to/from the unit. (Refer to Fig. 9)
*Using a tool other than a spanner can damage the head of the
flare nut, and gas leakage can occur due to tightening failure.
• Refer to “Table 2” for the dimensions for flaring.
• When connecting the flare nut, apply ester oil or ether oil to the
inside of flared section, and turn the nut spin 3-4 times by hand
before screwing in. (Refer to Fig. 10)
Be careful not to damage the flare section.
Table 2
Pipe size Tightening torque Flare dimensions A (mm) Flare

φ15.9 (5/8”) 61.8 - 75.4 N·m 19.3 - 19.7
• Refer to “Table 2” to determine the proper tightening torque.
Overtightening may damage the flare and cause a refrigerant leakage.
When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque
suddenly increases.
From that point, further tighten and turn the flare nut the angle shown below. (Refer to Table 3)
After the work is finished, make sure to check that there is no leak.
Unless you tighten as instructed, (if it is loosely tightened), it may lead to the refrigerant leakage (slow
leak) and cause malfunction of the device (such as insufficient cooling or heating).
