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 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.

•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.
•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.

4 DRAIN PIPING WORK
REQUIREMENT
•Be sure to perform heat insulation of the drain pipes of the indoor unit.
•Never forget to perform heat insulation of the connecting part with the
indoor unit. An incomplete heat insulation causes dewing.
•Set the drain pipe with downward slope (1/100 or more), and do not
make swelling or trap on the piping. It may cause an abnormal sound.
•For length of the traversing drain pipe, restrict to 20m or less.
In case of a long pipe, provide support brackets with interval of
1.5 to 2m in order to prevent waving.
•Set the collective piping as shown in the right figure.
•Do not mount an air purge pipe,
otherwise drain water spouts
out resulted in water leak.
CAUTION
•Following the 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.
When the electric work has finished:
•Before installing a panel, pour water (500cc) as shown in the following figure, check water is drained from the
drain pipe connecting port in COOL mode, and then check there is no water leak from the drain pipes.
When the electric work has not finished:
•Pull out the float switch connector (2P: White). (In this time, be sure to check the power is turned off.)
•Connect the single-phase 220-240V 50Hz (or 220V 60Hz) power to the terminal blocks R (L) and S (N).
(Never apply 220-240V to (A), (B), (U1),and (U2), otherwise a trouble of P.C. board occurs.)
•When the power is turned on, the drain pump motor drives automatically. Check water is drained from the drain
pipe connecting port, and then check there is no water leak from the drain pipes.
•After check of draining and water leak, turn off the power supply, attach the float switch connector to the original

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.
•Refer to the following table for tightening torque.
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.
•Using the attached heat insulating pipe, perform heat
insulating process securely for pipe connecting part of
the indoor units without clearance.
REQUIREMENT
Apply the thermal 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.)
