3. GENERAL SPECIFICATION
This installation manual briefly 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
Refer to the installation manual for the outdoor unit for description of allowable pipe
length and height difference.

• Wrap heat insulation around both gas pipe and 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
a thickness of 15 mm or more.
If the expected humidity is higher than 80 %, use heat insulation that has a thickness
of 20 mm or more.
• The use 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.

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
(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
1
dimensions". Also install the unit where the fi lter can be removed.
Correct initial installation location is important because it is diffi cult to move the unit after it
is installed.
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.
Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts, caus-
ing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam, such
as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit to leak
water.
• Area where is close to heat sources.
• Area that generates substances that adversely affect the equipment, such as sulfuric
gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints to cor-
rode, which can cause refrigerant leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile in fl ammables such as paint thinner or gasoline.
• If gas leaks and settles around the unit, it can cause a fi re.
• Area where animals may urinate on the unit or ammonia may be generated.
• Do not use the unit for special purposes, such as storing food, raising animals, grow-
ing plants, or preserving precision devices or art objects. It can degrade the quality of
the preserved or stored objects.
• Install the unit where drainage does not cause any trouble.
• Install the indoor unit, outdoor unit, power supply cable, transmission cable, and re-
mote control cable at least 1 m away from a television or radio receivers. The purpose
of this is to prevent TV reception interference or radio noise.
(Even if they are installed more than 1 m apart, you could still receive noise under
some signal conditions.)
• If children under 10 years old may approach the unit, take preventive measures so that
they cannot reach the unit.
• Install the indoor unit on the wall where the height from the fl oor is more than 1.8 m.
6. INSTALLATION WORK
During transportation or relocation of the indoor unit, pipes shall be covered with the
wall hook bracket for protection. Do not move the appliance by holding the indoor unit
pipes.
(The stress applied to the pipe joints may cause the fl ammable gas to leak during
operation.)
