CONNECTION PIPE REQUIREMENT
WARNING
Do not use the existing (for R22) piping and fl are nuts.
• If the existing materials are used, the pressure inside the refrigerant cycle will rise
and cause failure, injury, etc. (Use the special R410A materials.)
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 failure, injury, etc.

3. GENERAL
This INSTALLATION MANUAL briefl y outlines where and how to install the air conditioning
system. Please read over the entire set of instructions for the indoor and outdoor units and
make sure all accessory parts listed are with the system before beginning.

3.1. Type of copper pipe and insulation material
CAUTION
Refer to the installation manual for the outdoor unit for description of allowable pipe
length and height difference.

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 specifi ed, condensation may form on
the surface of the insulation. In addition, use heat insulation with heat conductivity of
0.045 W/(m•K) or less (at 20 °C).

4. ELECTRICAL REQUIREMENT
The indoor unit is powered from the outdoor unit or branch box. Do not power indoor unit
from separate power source.
WARNING
Refer to local codes for acceptable cable type.
Cable
Type
Remarks
Connection cable
Type 60245 IEC57
3 cable + Earth (Ground), 1 Ø 230V
Max. Cable Length: Limit voltage drop to less than 2%. Increase cable gauge if voltage
drop is 2% or more.
5. SELECTING THE MOUNTING POSITION
Decide the mounting position with the customer as follows:
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed: the air should be able to blow all
over the room.
(3) Install the unit a dedicated electrical branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit or branch box is easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the spaces shown in the figure. Also
install the unit where the filter can be removed.
Correct initial installation location is important because it is diffi cult to move unit after it is
installed.
