CONNECTION PIPE REQUIREMENT
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 0.045 W/(maK) or less (at 20 C).
Use pipe with water-resistant heat insulation.
CAUTION
The maximum lengths of this product are shown in the following table. If the units are further apart than this, correct

WARNING
For the air conditioner to operate satisfactorily. install it as outlined in this installation instruction sheet.
Connect the indoor unit and outdoor unit with the room air conditioner piping and cords available standards parts. This
installation instruction sheet describes the correct connections using the installation set available from our standard parts.
Installation work must be performed in accordance with national wiring standards by authorized personnel only.
Also, do not use an extension cord.
Do not turn on the power until all installation work is complete.
Do not purge the air with refrigerants but use a vacuum pump to vacuum the installation.
There is not extra refrigerant in the outdoor unit for air purging.
Use a vacuum pump for R410A exclusively.
Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit.
Use a clean gauge manifold and charging hose for R410A exclusively.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant comes in contact with a flame, it
produces a toxic gas.
Be careful not to scratch the air conditioner when handling it.
After installation, explain correct operation to the customer, using the operating manual.
Let the customer keep this installation instruction sheet because it is used when the air conditioner is serviced or moved.
