•  Where it is not exposed to strong wind.

•  Where airflow is good and dustless.

•  Where rain or direct sunshine can be avoided as much as possible.

•  Where neighbours are not annoyed by operation sound or hot air.

•  Where rigid wall or support is available to prevent the increase of operation

sound or vibration.

•  Where there is no risk of combustible gas leakage.

•  When installing the unit, be sure to secure the unit legs.

•  Where it is at least 3 m (10 ft.) away from the antenna of TV set or radio.

Operation of the air conditioner may interfere with radio or TV reception in

areas where reception is weak. An amplifier may be required for the affected

device.

•  Install the unit horizontally.

•  Please  install  it  in  an  area  not  affected  by  snowfall  or  blowing  snow.  In

areas with heavy snow, please install a canopy, a pedestal and/or some

baffle boards.

It is advisable to make a piping loop near outdoor unit so as to reduce vibra-

tion transmitted from there.

When operating the air conditioner in low outside temperature, be sure to

follow the instructions described below.

•  Never install the outdoor unit in a place where its air inlet/outlet side may

be exposed directly to wind.

•  To prevent exposure to wind, install the outdoor unit with its air inlet side

facing the wall.

•  To prevent exposure to wind, it is recommended to install a baffle board on

the air outlet side of the outdoor unit.

Avoid the following places for installation where air conditioner trouble is li-

able to occur.

•  Where flammable gas could leak.

•  Where there is much machine oil.

•  Salty places such as the seaside.

•  Where sulfide gas is generated such as a hot spring.

•  Where there is high-frequency or wireless equipment.

•  Where there is emission of high levels of VOCs, including phthalate com-

pounds, formaldehyde, etc., which may cause chemical cracking.

When there is an obstacle in front of the unit as shown in the figure, open

space above, behind, and on the sides of the unit is required.

As long as space indicated in the figure is provided, it is allowed to install

the unit where obstacles are behind and on the sides of the unit. (No ob-

stacle above the unit)

Service space

•  When installing the unit in an area that is enclosed with walls such as a

verandah, be sure to have enough space as shown below.

 In this case, the air conditioning capacity and power consumption might

deteriorate.

•  When installing two or more units, do not install the units in front or be-

hind each other.

When there is no obstacle in front and on the sides of the unit, it is allowed

to  install  the  unit  where  an  obstacle  is  above  the  unit  only  if  the  space

shown in the figure is provided.

Provide space for service and maintenance as shown in the figure.
