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.
WARNING
•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 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 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 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 are 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 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.

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
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.
•In the process after removing the ceiling panel, it important to reinforce the groundwork (framework) and keep a
level correctly of the existing ceiling to prevent vibration of the ceiling panel.
•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)
•Place where noise of the outdoor unit is easily transmitted.
(When installing the air conditioner on the boundary with the neighbor, pay due attention to the level of noise.)
•Place with poor ventilation.
(Before air ducting work, check whether value of air volume, static pressure and duct resistance are correct.)
•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 wires 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.

5 DRAIN PIPING WORK
CAUTION
•Following the Installation Manual, perform the drain piping work so that water is properly drained, and apply a
heat insulating so as not to cause a dewing. Inappropriate piping work may result in water leakage in the room
and wet of furniture.
REQUIREMENT
•The draining method is a natural draining. Therefore, slope the piping outside of the unit downward (at 1/50 to
1/100), and do not put an angle halfway. If doing so, an abnormal sound may be caused.
•To prevent overflow of drain pipe, set a drain trap on its way as shown in the right figure.
[The drain trap is required for preventing aspiration of smell through the drain pipe, and also for preventing
hardness of draining because the differential pressure between the drain pan and atmosphere becomes large
when the external static pressure is high (especially, at suction side).]
•Dust inside of the drain pipe is easy to be heaped at the drain trap. Be sure to set a plug so that the drain trap
can be cleaned.
•Maximum horizontal drain pipe length should be less than 20m or shorter.
If the pipe is long, set the support brackets with 1.5 to 2m interval to prevent waving.
•Mount the collective drain pipe as shown in the right figure.
•Do not mount an air purge pipe.
Otherwise drain water spouts out resulted in water leak.
•Do not apply strength to the connecting part with the
drain pipe.
•Do heat insulating securely to the indoor drain pipe.
•Be sure to do heat insulating to the connecting part
with the indoor unit.
Incomplete heat insulating may cause dewing.
Piping/Heat insulating material
The following materials as below for piping and heat
insulating prpcess are procured locally.
Check the draining
Check the water drainage is surely performed at the
trial operation.
Check also no water leakage is found at the pipe
connecting part.
REQUIREMENT
Enter water gradually using a kettle or a hose from
drain pan of the discharge port.
Drain up
When not securing down slope on the drain pipe, use
a drain up kit sold separately. Also refer to the “Drain
up kit installation manual”.
Check the draining
After drain piping work, check that water drain is
properly performed and water does not leak from the
connecting part of the pipes. In this time, check also
there is no abnormal sound of the motor of the drain
pump. Be sure to check draining when installed in the
heating period.
CAUTION
Pour water slowly.
If it is poured urgently, water is spread inside of the
indoor unit resulted in a trouble.

6 REFRIGERANT PIPING
WARNING
•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 may
generate.
REQUIREMENT
When the refrigerant pipe is long, set the support brackets to fix the pipe with 2.5 to 3m intervals. If the pipe is
not fixed, abnormal sound may generate.
Be sure to use the flare nuts attached to the indoor unit or those fro R410A.

Pipe Forming/End Positioning
Flaring
1. Cut the pipe with a pipe cutter.
2. 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.

Connection of refrigerant pipe
Connect all the refrigerant pipes with flare connecting
work.
•Since the atmospheric pressure only is sealed
as the sealing gas, it is not abnormal that
“Pushu…” sound is not heard when the flare
nut is removed.
•Be sure to use a double spanner for pipe
connecting work of the indoor unit.
Airtight test/Air purge, etc.
For airtight test, air purge, addition of refrigerant, and
gas leak check, follow the Installation Manual attached
to the outdoor unit.
REQUIREMENT
Be sure to use the tool such as charge hose
exclusive to R410A.
Do not turn on the power until the airtight test and
the vacuuming have finished. (If turning on the
power, the incorporated PMV is closed fully and
the period until the vacuuming finishes elongates.
Open fully valves of the outdoor unit
Gas leak check
Check with a leak detector or soap water whether gas
leaks or not, from the pipe connecting section or cap
of the valve.
REQUIREMENT
Use a leak detector manufactured exclusively for
HFC refrigerant (R410A, R134a, etc.).
Heat insulating process
Perform heat insulating for pipes at liquid side and gas
side separately.
In cooling time, temperature at both liquid and gas
sides becomes lower.
Therefore, perform heat insulating process sufficiently
to avoid dewing.
•For heat insulator of pipe at gas side, be sure to use
one with heat-resisting temp.120°C or more.
REQUIREMENT
Apply the heat insulation to the pipe connecting
section of the indoor unit securely up to the root
without exposure of the pipe. (The pipe exposed to
the outside causes water leak.)
