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 R32/R410A materials.)
• Use (refi ll or replace with) specifi ed refrigerant (R32) only. Use of unspecifi ed refriger-
ant can cause product malfunction, burst, or injury.
• Do not mix any gas or impurities except specifi ed refrigerant (R32). Infl ow of air or ap-
plication of unspecifi ed material makes the internal pressure of the refrigerant cycle too
high, and may cause product malfunction, burst of piping, or injury.
• For appropriate working of the air conditioner, install it as written in this manual.
• To connect indoor unit and outdoor unit, use air conditioner piping and cables available
through your local distributor. This manual describes proper connections using such
installation set.
• Do not turn on the power until all work has been completed.
CAUTION
This manual describes how to install the indoor unit only. To install the outdoor unit, (if
any), refer to the installation manual included in each product.

3. GENERAL SPECIFICATION
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 of the outdoor unit for description of the length of
connecting pipe or for difference of its elevation.
Gas pipe size (thickness) [mm] Liquid pipe size (thickness) [mm]
Ø
9.52 (3/8 in.)
Ø
6.35 (1/4 in.)
CAUTION
• Wrap heat insulation around both of the gas pipe and the liquid pipe.
No heat-insulation work or incorrect heat-insulation work may cause water leaks.
• In a reverse cycle model, use heat insulation with heat resistance above 120 °C.
• If expected humidity of the installation location of refrigerant pipes is higher than 70
%, wrap the heat insulation around the refrigerant pipes.
If the expected humidity is between 70 % and 80 %, use heat insulation that has
thickness of 15 mm or more.
If the expected humidity is higher than 80 %, use heat insulation that has thickness
of 20 mm or more.
• Using of thinner heat insulation than specifi ed above may cause a condensation on
the surface of the insulation.
• Use heat insulation with thermal conductivity of 0.045 W/(
m•K
) or less, at 20
°C
.
3.2. Additional materials required for installation
A. Refrigeration (armored) tape
B. Insulated staples or clamps for connecting wire (See your local electrical codes.)
C. Putty
D. Refrigeration lubricant
E. Clamps or saddles to secure refrigerant piping
4. ELECTRICAL REQUIREMENT
The indoor unit is powered from the outdoor unit. Do not power indoor unit from separate
power source.
WARNING
Standard for electrical wiring and equipment differs in each country or region. Before you
start electrical working, confi rm related regulations, codes, or standards.

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 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 “6.1. Installation
dimensions”. Also install the unit where the fi lter can be removed.
(8) This product has a wireless LAN adapter as accessory. Refer to “7.4.1. Before
installing wireless LAN adapter” to decide on the place of installation.
Correct initial installation location is important because it is diffi cult to move the unit after it
is installed.
WARNING
Install the indoor unit where is capable to support the weight of the unit. Secure the
unit fi rmly so that the unit does not topple or fall.
