INSTALLATION INSTRUCTIONS
NOTES:
• OD unit cannot hang from a ceiling or be stacked.
• If installing the OD unit with a fence or rail guard around it,
ensure that accumulated snow, debris, etc... will not block
the air inlet or the coil exchanger.
• Ensure ventilation in case of refrigerant leakage. R-410A is
a safe, nontoxic, and nonflammable refrigerant.
• Avoid installing the OD unit where corrosive gases, such as
sulfur oxides, ammonia, and sulfurous gas are produced. If
unavoidable, consult with an installation specialist about
using a corrosion-proof or anti-rust additive to protect the
unit coils.
• Do not install the outdoor unit near the edge of a balcony.
Otherwise, children may climb onto the outdoor unit and fall
off of the balcony.
• Do not install the outdoor unit in thw following areas: Area
filled with mineral oil or containing a large amout of splashed
oil or steam, such as a kitchen. It will deterorate plastic
partic parts, causing the parts to fail or the unit to leak
water.
• Area that can cause combustible gas to ledk, contains
suspended carbon fibers or flammable dust, or volatile
inflammables such as pain thinner or gasoline. If gas leaks
and settles around the unit, it can cause a fire.
• Area where small animals may live. It may cause failure,
smoke or fire if small animals enter and touch inernal
electrical parts.
• Area where animals may urinate on the unit or ammonia
may be generated.
• 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.
• If the outdoor unit is installed in a cold region that is
affected by snow accumulation, snow fall, or freezing, take
A. Select the Indoor location:
• Do not allow any heat or steam near the unit.
• Select a location where there are no obstacles in
front of the unit.
• Make sure that condensate drainage can be
conveniently routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right of
the unit is more than 4". The unit should be installed
as high on the wall as possible but allow a minimum
of 4" from the ceiling.
• Use a stud finder to locate and mark stud locations
for mounting and to prevent unnecessary damage
to the wall.
• Install in a location that is strong enough to
withstand the full weight and vibration of the unit.
• Leave enough space to allow access for routine
maintenance.
• Select a location that gives easy access to removing
and cleaning air filters.
• Install in a location that is 3 ft. or more away from
other electrical appliances, such as televisions and
audio devices.

Step 2 - Installation of the Indoor Unit
appropriate measures to protect it from those elements. To
ensure a stable operating, install inlet and outlet ducts.
• Make sure the outdoor unit is installed level and is stable.
Install snow protection hood as necessary.
• Avoid salty places such as the seaside for installation where
air conditioner trouble is liable to occur.
• 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 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.
• It is recommended that unit be installed under a canopy or
elevated on a high stand.
• In places where the outdoor temperature drops to 32°F
(0°C) or lower, the drain water may freeze and may stop up
the drain or cause other outdoor unit trouble. Therefore
take measures so that the drain water will not freeze and
clog the drain.
• Please set up the outdoor unit in a high place and pleade
do not arrange the frame of installed stand under the
drain port, because the water dropped from the drain port
repeats freezing and accumulating, and may block the drain
port.
• Do not use mineral oil on a flaredf part. Precent mineral
oil from getting into the syetem as this would reduce the
lifetiome of the units.
• While welding the pipes, be sure to blow dry nitrogen gas
through them.
• The maximum lengths of this product are shown in the
table. If the units are further apart than this , correct
operation cannot be guaranteed.
B. Install the Mounting Plate
• Remove plastic bag, tape, and mounting plate from
the back of the indoor unit.
• Place the mounting plate on the wall in the desired
location taking into account the minimum clearances
necessary for proper operation.
• Using a level, verify that the mounting plate is
horizontal and mark the screw locations.
• Attach the mounting plate to the wall with the
supplied screws.
• If not able to align all screw holes with studs, wall
anchors are supplied.
• Be sure that the mounting plate has been attached
firmly and that applied weight is evenly distributed
by each screw. (At least one screw in wall stud,
others can use wall anchors.)
• The piping for the indoor unit may be routed to and
from the unit in one of several directions: left, left
rear, right, right rear, or right below. See Illustration
on page 7.
