 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 248 °F (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 3/4 in. (15 mm) or 
thicker and if the expected humidity exceeds 80%, use heat insulation that is 13/16 in. 
(20 mm) or thicker.
If heat insulation is used that is not as thick as speci

fi

 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 [68 °F (20 °C)]).

3.2. Electrical requirement

The indoor unit is powered from the outdoor unit. Do not power indoor unit from separate 
power source.

 WARNING

 Refer to local codes for acceptable cable type.

4.  SELECTING THE INSTALLATION LOCATION

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 [5.1. Installation 

dimensions]. Also install the unit where the 

fi

 lter can be removed.

Correct initial installation location is important because it is dif

fi

 cult to move unit after it is 

installed.

 WARNING

 Install the air conditioner in a location which can withstand a load of at least 3 times the 
weight of the main unit and which will not amplify sound or vibration. If the installation 
location is not strong enough, the indoor unit may fall and cause injuries.

Withstandable weight (Unit weight x 3*)

93 Lbs (42kg)

*In accordance with UL standards.

 CAUTION

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 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 corrode, 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.

•  Do not install where there is the warning of combustible gas leakage.
•  Do not install the unit near a source of heat, steam, or 

fl

 ammable gas.

•  Install the unit where drainage does not cause any trouble.
•  Install the indoor unit, outdoor unit, power supply cable, transmission cable, and 

remote control cable at least 40 in. (1m) 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 40 in. (1m) 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

 oors more than 70 in. 

(1.8 m).

5.3. Cutting the hole in the wall for the connecting pipes

(1)  Cut a 3-1/8 in. (80 mm) diameter hole in the wall at the position shown in the 

fi

 gure.

(2)  When cutting the wall hole at the inside of the wall hook bracket, cut the hole to a point 

of intersection of center marks.

 

 When cutting the wall hole at the outside of the wall hook bracket, cut the hole at a 
point of 3/8 in. (10 mm) below.

(3)  Cut the hole so that the outside end is lower [3/16 to 3/8 in. (5 to 10 mm)] than the inside end.
(4)  Always align the center of the wall hole. If misaligned, water leakage will occur.
(5)  Cut the wall pipe to match the wall thickness, stick it into the wall cap, fasten the cap 

with vinyl tape, and stick the pipe through the hole.

(6)  For left piping and right piping, cut the hole a little lower so that drain water will 

fl

 ow freely.
