Do not install the outdoor unit in the following areas:
• Area with high salt content, such as at the seaside. It will deteriorate metal parts,
causing 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 containing equipment that generates electromagnetic interference. It will
cause the control system to malfunction, preventing the unit from operating
normally.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fi re.
• Area that has heat sources, vapors, or the risk of the leakage of fl ammable gas in
the vicinity.
• Area where small animals may live. It may cause failure, smoke or fi re if small
animals enter and touch internal electrical parts.
• Area where animals may urinate on the unit or ammonia may be generated.
Do not tilt the outdoor unit more than 0.3 degrees.
Install the outdoor unit in a well-ventilated location away from rain or direct sunlight.
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 airfl ow 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 unit in an area that would not cause problems even if the drain water is
discharged from the unit. Otherwise, provide drainage that would not affect people or
objects.
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
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)
• If you are installing the drain pipe and drain caps,
please provide a working space under the base of
the outdoor unit.
• As the drain water fl ows 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 model only)

3.3. Installation dimensions
Consider the transportation route, installation space, maintenance space, and access,
and install the unit in a location with suffi cient space for the refrigerant piping.
Keep the space shown in the installation
examples.
If the installation is not performed accordingly, it
could cause a short circuit and result in a lack of
operating performance.
Do not obstruct the air intake of the outdoor unit
with piping, wiring, stand, etc.
Installation methods not shown in the following examples are not recommended.
Performance may drop signifi cantly.
