1 PRECAUTIONS FOR SAFETY
•Ensure that all Local, National and International regulations are satisfied.
•Read this “PRECAUTIONS FOR SAFETY”carefully before Installation.
•The precautions described below include the important items regarding safety. Observe them without fail.
•After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
•Turn off the main power supply switch (or breaker) before the unit maintenance.
•Ask the customer to keep the Installation Manual together with the Owner’s Manual.
CAUTION New Refrigerant Air Conditioner Installation
•THIS AIR CONDITIONER ADOPTS THE NEW 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 new 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 charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new 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.
CAUTION To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of
at least 3 mm.
The installation fuse (25A D type ) must be used for the power supply line of this conditioner.
WARNINGS
•Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
•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 cable correctly.
If the connecting cable 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 specified 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 resultingly 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.

•Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•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 specified 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 fire, noxious gas may generate.
•After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might
generate.
•Electrical work must be performed by a qualified electrician in accordance with the
Installation Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
•Use the specified cables for wiring connect the terminals securely fix. 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 fire may occur.

Installation space
Secure the specified space in the figure for installation and servicing.
2 SELECTION OF INSTALLATION PLACE
WARNING
•Install the air conditioner at enough strong place to withstand the weight of the unit.
If the strength is not enough, the unit may fall down resulting in injury.
•Install the air conditioner at a height 2.5m or more from the floor.
If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous
because you may contact with revolving fan or active electricity.
CAUTION
•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 fire may occur.
Upon approval of the customer, install the air conditioner in a place that satisfies the
following conditions.
•Place where the unit can be installed horizontally.
•Place where a sufficient servicing space can be ensured for safety maintenance and check.
•Place where drained water will not cause any problem.
Avoid installing in the following places.
•Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas
(hot spring). (Should the unit be used in these places, special protective measures are needed.)
•Place exposed to oil, vapor, oil smoke or corrosive gas.
•Place where organic solvent is used nearby.
•Place close to a machine generating high frequency.
•Place where the discharged air blows directly into the window of the neighboring house. (For outdoor unit)

Selection of installation place
In case of continued operation of the indoor unit under
high-humidity conditions as described below, dew may
condense and water may drop.
Especially, high-humidity atmosphere (dew point
temperature : 23°C or more) may generate dew inside the
ceiling.
1. Unit is installed inside the ceiling with slated roof.
2. Unit is installed at a location using inside of the ceiling
as fresh air take-in path.
3. Kitchen
If installing a unit at such place, put insulating material
(glass wool, etc.) additionally on all the positions of the
indoor unit which come to contact with high-humidity
atmosphere.
Advice
Set a service check opening panel at right side of the unit
(size: 450 ×450mm or more) for piping, maintenance,

Ceiling height
When the height of the ceiling exceeds the distance of the
item Standard/4-way in Table below, the hot air is difficult to
reach the floor. Therefore, it is necessary to change the
setup value of the high ceiling switch or discharge direction.
REQUIREMENT
•When using the air conditioner with 2-way discharge
system with the standard setting (at a shipment), it
may stop abnormally in heating. Therefore, change
the setting switch according to the number of
discharge direction and the ceiling height.
•When using the air conditioner with 2-way/3-way
discharge system, a strong wind blows directly if
the ceiling height is lower than the standard.
Therefore, change the setting switch according to
height of the ceiling.
•When using the high ceiling (1) or (2) with 4-way
discharge system, the draft is apt to be felt due to
drop of the discharge temperature.
Discharge direction

Connection procedure
Connect a socket and a hard vinyl chloride pipe.
•Using adhesive agent for vinyl chloride pipe, connect
the drain pipes certainly so that water does not leak.
•It takes approx. 10 hours to dry and harden the
adhesive agent. During this period, do not apply
force to the connecting part with the drain pipe.
Perform heat insulating.
•As shown in the figure, cover the flexible hose and
hose band with the attached heat insulator up to the
bottom of the indoor unit without gap.
Drain up
When a downward grading cannot be secured on the
drain pipe, drain-up up to 640mm is possible.
Set downward grading immediately after raising up
vertically.
Check the draining
In the test run, check that water drain is properly
performed and water does not leak from the
connecting part of the pipes.
Be sure to check draining also when installed in
heating period.
Using a pitcher or hose, pour water (1500 to 2000cc)
into the discharge port before installation of the ceiling
panel.
Pour water gradually so that water does not spread on
the motor of the drain pump.
•After the electric work has finished, pour water
during COOL mode operation.
•If the electric work has not yet finished, pull out the
float switch connector (CN34 : Red) from the electric
parts box, and check draining by plugging the single
phase 220–240V power to the terminal blocks Q
and R.
If doing so, the drain pump motor operates.
•Test water drain while checking the operation sound
of the drain pump motor.
(If the operation sound changes from continuous
sound to intermittent sound, water is normally
drained.)
After the check, the drain pump motor runs,
connecting the float switch connector.
(In case of check by pulling out the float switch
connector, be sure to return the connector to the
original position.)

4 REFRIGERANT PIPING AND EVACUATING
Refrigerant Piping
1. If the outdoor units are to be mounted on a wall,
make sure that the supporting platform is
sufficiently strong. The platform should be
designed and manufactured to maintain its strength
over a long period of time, and sufficient
consideration should be given to ensuring that the
outdoor unit will not fall.
2. Use copper pipe with 0.8 mm or more thickness.
(In case pipe size is Ø15.9, with 1.0mm or more.)
3. Flare nut and flare works are also different from
those of the conventional refrigerant.
Take out the flare nut attached to the main unit of
the air conditioner, and use it.
CAUTION
IMPORTANT 4 POINTS FOR PIPING WORK
1. Remove dust and moisture from the inside of
the connecting pipes.
2. Tight connection (between pipes and unit)
3. Evacuate the air in the connecting pipes using
VACUUM PUMP.
4. Check the gas leakage. (Connected points)
Permissible Piping Length and Heat
They vary according to the outdoor unit. For details,
refer to the Installation Manual attached to the outdoor
unit.
Flaring
Insert a flare nut into the pipe, and flare the pipe.
As the flaring sizes of R410A differ from those of
refrigerant R22, the flare tools newly manufactured for
R410A are recommended.
However, the conventional
tools can be used by
adjusting projection
margin of the copper pipe.

*In case of flaring for R410A with the conventional
flare tool, pull it out approx.
0.5 mm more than that for R22 to
adjust to the specified flare size.
The copper pipe gauge is useful
for adjusting projection margin size.
Tightening connection
CAUTION
•Do not apply excessive torque. Otherwise, the
nut may crack depending on the conditions.
(Unit : N•m)
•Tightening torque of flare pipe connections
Pressure of R410A is higher than that of R22.
(Approx. 1.6 times) Therefore, using a torque
wrench, tighten the flare pipe connecting sections
which connect the indoor
and outdoor units of the
specified tightening torque.
Incorrect connections may
cause not only a gas
leak, but also a trouble
of the refrigeration cycle.
Align the centers of the connecting pipes and tighten
the flare nut as far as possible with your fingers. Then
tighten the nut with a spanner and torque wrench as
shown in the figure.
