1PRECAUTIONS FOR SAFETY
Installing, starting up, and servicing air conditioning equipment can
be hazardous due to system pressures, electrical components,
and equipment location (roofs, elevated structures, etc.).
Only trained, qualied installers and service mechanics should
install, start up, and service this equipment.
Untrained personnel can perform basic maintenance functions
such as indoor unit air lter. All other operations should be
performed by trained service personnel.
Before working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.
Follow all safety codes. Wear safety glasses and work gloves.
Use care in handling, rigging, and setting bulky equipment.

cautions included in literature and attached to the unit.
Consult local building codes and National Electrical Code (NEC)
for special requirements. Recognize safety information. This is the
safety alert symbol . When you see this symbol on the unit and
in instructions or manuals, be alert to the potential for personal
injury. Understand these signal words: DANGER, WARNING,
and CAUTION. These words are used with the safety alert symbol.
DANGER identies the most serious hazards which will result
in severe personal injury or death. WARNING signies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability,
or operation.
The manufacturer shall not assume any liability for the damage
caused by not observing the description of this manual.
WARNING
• Ask an authorized dealer or qualied installation
professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric
shock or re.
• Turn off the main power supply switch or breaker before
attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause
electric shock.
• Connect the connecting wire correctly.
If the connecting wire is connected in a wrong way, electric parts
may be damaged.
• When moving the air conditioner for the installation into
another place, be very careful not to enter any gaseous
matter other than the specied refrigerant into the
refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas
pressure in the refrigeration cycle becomes abnormally high and
it as a result causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety
guards or by by-passing any of the safety interlock
switches.
• Exposure of unit to water or other moisture before
installation may cause a short-circuit of electrical parts.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully if there is
possible damage.
• Do not install in a place that might increase the vibration of
the unit.
• To avoid personal injury (with sharp edges), be careful when
handling parts.
• Perform installation work properly according to the
Installation Manual.
Inappropriate installation may result in water leakage, electric
shock or re.

CAUTION
Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE HFC REFRIGERANT
(R410A) WHICH DOES NOT DESTROY OZONE LAYER.
The characteristics of R410A refrigerant are ; easy to absorb
water, oxidizing membrane or oil, and its pressure is approx.
1.6 times higher than that of refrigerant R22. Accompanied
with the refrigerant, refrigerating oil has also been changed.
Therefore, during installation work, be sure that water, dust, former
refrigerant, or refrigerating oil does not enter the refrigerating
cycle.
To prevent charging an incorrect refrigerant and refrigerating oil,
the sizes of connecting sections of charging port of the main unit
and installation tools are changed from those for the conventional
refrigerant.
Accordingly the exclusive tools are required for the refrigerant
(R410A).
For connecting pipes, use new and clean piping designed for
R410A, and please care so that water or dust does not enter.
Moreover, do not use the existing piping because there are
problems with pressure-resistance force and impurity in it.
• When the air conditioner is installed in a small room,
provide appropriate measures to ensure that the
concentration of refrigerant leakage occur in the room does
not exceed the critical level.
• Install the air conditioner securely in a location where the
base can sustain the weight adequately.
• Perform the specied installation work to guard against an
earthquake.
If the air conditioner is not installed appropriately, accidents may
occur due to the falling unit.
• If refrigerant gas has leaked during the installation work,
ventilate the room immediately.
If the leaked refrigerant gas comes in contact with re, noxious
gas may generate.
• After the installation work, conrm that refrigerant gas does
not leak.
If refrigerant gas leaks into the room and ows near a re source,
such as a cooking range, noxious gas might generate.
• Electrical work must be performed by a qualied electrician
in accordance with the Installation Manual.
Make sure the air conditioner uses an exclusive power
supply.
An insufcient power supply capacity or inappropriate installation
may cause re.
• Use the specied wires for wiring connect the terminals
securely x.
To prevent external forces applied to the terminals from
affecting the terminals.
• Conform to the regulations of the local electric company
when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to
a risk of exposure to a combustible gas.
If a combustible gas leaks, and stays around the unit, a re may
occur.

2SELECTION OF INSTALLATION PLACE
CAUTION
Do not install the air conditioner at place where combustible gas may leak.
If gas leaks is collected at surrounding the unit, the production of re may be caused.
Cautions for Installation at a Place with the Quiet Background Sound
As the Flow Selector unit incorporates the Pulse motor valve, the refrigerant sound or the operating sound of
the Pulse motor valve such as “Bushuu...” generates when exchanging between cooling and heating mode and
during defrost operation. Therefore, avoid installing the unit at a place with quiet background sound as follows.
(1) Rooms with quiet background sound such as bedroom, hospital, or room in a hotel.
(2) Rooms which have no ceiling and a fabric does not block the residence space from the Flow Selector
unit.
(3) Rooms which have opening port at the ceiling.
Flow Selector unit Indoor unit
32.3 ft (10 m) or more
When installing the unit at the above places, separate the unit from the indoor unit (more than 32.3 ft (10 m))
and install the unit at a place so that sound does not transmit into the room such as in the corridor ceiling.
And take sound proof measure, such as covering around the Flow Selector unit with the sound proong
materials.
Upon customer’s approval, install the air conditioner at a place where satises the following conditions.
• Place where Flow Selector unit can be installed horizontally.
• Place which can reserve a service space for safe maintenance or check.
Apply electric insulation between metal section of the building and metal section of the air conditioner in
conformance with the Local Regulation.
Avoid the following places.
• Salty place (seaside area) or place with much gas sulde (hot spring area)
(If selecting such a place, a special maintenance is required.)
• Place where oil (including machine oil), steam, oil smoke or corrosive gas generates.
• Place where a device generating high frequency (inverter, non-utility generator, medical apparatus, or
communication equipment) is set. (A bad inuence may generate by malfunction of the air conditioner, control
trouble, or noise for such equipment.)
Installation under high-humidity atmosphere
