1PRECAUTIONS 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 ADOPTSTHE 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 pres-
sure is approx.1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerat-
ing oil has also been changed. Therefore, during installation work, be sure that water, dust, former refriger-
ant, 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 16 A (All type fuse can be used) must be used for the power supply line
of this conditioner.
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 abnor-
mally high and it may 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 short-circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.

2
•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.
•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 Installa-
tion 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.
•Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
•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.

•In case of draining through the drain hose, attach
the following drain nipple and the waterproof rubber
cap, and use the drain hose (Inner diam.:16 mm)
sold on the market.And also seal the screws
securely with silicone material, etc. so that water
does not drop down.Some conditions may cause

For Reference
If a heating operation would be continuously per-
formed for a long time under the condition that the
outdoor temperature is 0 °C or lower, draining of
defrosted water may be difficult due to freezing of the
bottom plate, resulting in a trouble of the cabinet or
fan.
It is recommended to procure an anti-freeze heater
locally for a safety installation of the air conditioner.

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 manufac-
tured for R410A are recommended.
However, the conventional tools can
be used by adjusting projection
margin of the copper pipe.
•Flaring size : A (Unit : mm)

•Align the centers of the connecting pipes and
tighten the flare nut strong as far as possible with
your fingers.
Then fix the nut with a spanner and tighten it with
torque wrench as shown in the figure.
•As shown in the figure, be sure to use a double
spanner to loosen or tighten the flare nut of the
valve at gas side.If using a single spanner, the nut
cannot be tightened with necessary tightening
torque.
On the contrary, use a single spanner to loosen or
tighten the flare nut of the valve at liquid side.
SM80 type valve at gas side
•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/outdoor units at the
specified tightening torque.Incomplete connections
may cause not only a gas leak, but also a trouble of
the refrigeration cycle.
Do not apply refrigerating machine oil to
the flared surface.

REQUIREMENT
1. Do not put the spanner on the cap.The valve
may be broken.
2. If applying excessive torque, the nut may be

tions.
•After the installation work, be sure to check gas
