• 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.
Q'ty
• 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.
1
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
1
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
5
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
2
The indoor unit is powered from the outdoor unit. Do not power indoor unit from separate
power source.

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:
5.1. Indoor unit
Q'ty
1
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
1 set
(2) The inlet and outlet ports should not be obstructed : the air should be able to blow all
1
over the room.
(3) Install the unit a dedicated electrical branch circuit.
1 set
(4) Do not install the unit where it will be exposed to direct sunlight.
1
(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.
Correct initial installation location is important because it is diffi cult to move the unit after it
is installed.
Install the 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. 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 for preservation of food, plants, animals, precision equipment, art work, or
other objects. This may cause quality deterioration of those items.
• 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 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.
This product has an built-in WLAN adapter.
Refer to the Setting manual for wireless LAN control for air conditioning to decide on the
place of installation.
