CAUTION
If the outdoor unit must be installed in an area within easy reach of the general public,
install as necessary a protective fence or the like to prevent their access.
Install the outdoor unit in a location that would not inconvenience your neighbors, as
they could be affected by the airflow coming out from the outlet, noise, or vibration. If it
must be installed in proximity to your neighbors, be sure to obtain their approval.
If the outdoor unit is installed in a cold region that is affected by snow accumulation,
snow fall, or freezing, take appropriate measures to protect it from those elements. To
ensure a stable operation, install inlet and outlet ducts.
Install the outdoor unit in a location that is away from exhaust or the vent ports that
discharge vapor, soot, dust, or debris.
Install the indoor unit, outdoor unit, power supply cable, connection cable, and remote
controller 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.
Keep the length of the piping of the indoor and outdoor units within the allowable range.
For maintenance purposes, do not bury the piping.
3.2. Drain installation
CAUTION
Perform drain work in accordance with this Manual, and ensure that the drain water is
properly drained. If the drain work is not carried out correctly, water may drip down from
the unit, wetting the furniture.
When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe
and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may
freeze in extremely cold weather. (Reverse cycle model only)

Since the drain water flows out of the outdoor unit during heating operation, install the drain
pipe and connect it to a commercial 16 mm hose. (Reverse cycle model only)
When installing the drain pipe, plug all the holes other than the drain pipe mounting hole
in the bottom of the outdoor unit with putty so there is no water leakage. (Reverse cycle

3.3. Installation dimensions
CAUTION
Select installation locations that can properly support the weight of the indoor and
outdoor units. Install the units securely so that they do not topple or fall.
WARNING
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near heat source of heat, steam, or flammable gas.
If children under 10 years old may approach the unit, take preventive measures so that
they cannot reach the unit.
CAUTION
Install the unit where it will not be tilted by more than 3˚. However, do not install the unit
with it tilted towards the side containing the compressor.
When installing the outdoor unit where it may exposed to strong wind, fasten it securely.
Decide the mounting position with the customer as follows:
(1) Install the outdoor unit in a location which can withstand the weight of the unit and
vibration, and which can install horizontally.
(2) Provide the indicated space to ensure good airflow.
(3) If possible, do not install the unit where it will be exposed to direct sunlight.
(If necessary, install a blind that does not interfere with the airflow.)
(4) Do not install the unit near a source of heat, steam, or flammable gas.
(5) During heating operation, drain water flows from the outdoor unit.
Therefore, install the outdoor unit in a place where the drain water flow will not be
obstructed. (Reverse cycle model only)
(6) Do not install the unit where strong wind blows or where it is very dusty.
(7) Do not install the unit where people pass.
(8) Install the outdoor unit in a place where it will be free from being dirty or getting wet by
rain as much as possible.
