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 the following areas: Areas
heavily laden with oil or greasy vapors such as kitchens.
Oils and grease will create sticky layer on the coil and also
cause drainage problems, thus degrade unit performance.
• Corrosive areas that can potentially have combustible
gas leaks, contain suspended fibers or flammable dust, or
flammables such as paint thinner or gasoline can cause fires.
• Areas that contain small animals, rodents, reptiles or
insects that can infiltrate the equipment and cause damage
to internal components.
• 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
appropriate measures to protect it from those elements. To
ensure a stable operating, install inlet and outlet ducts.
A. Select the Indoor location:
• Do not expose the unit to unusual heat sources or
steam outlets.
• 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 1 - Preparation Cont.
Step 2 - Installation of the Indoor Unit
• 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 heat pump 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.
• Protect the drain line from freezing in areas where
temperature drops to 32°F (0°C) or lower.
• Please set up the outdoor unit in a high place and please
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 oils on flared parts. Prevent mineral oil
from entering the refrigerant system. Introduction of mineral
oil may reduce the system life.
• Be sure to use an inert gas such as nitrogen while brazing
any refrigerant lines to prevent any oxidation
• Be sure not to exceed refrigerant tubing length limits
mentioned in table on page 15 for different models to
ensure smooth operation of the unit. Otherwise the
equipment life 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.
