2PRECAUTIONS 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.
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.
•Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
•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.
Use an exclusive power circuit for the air conditioner. Use the rated voltage.
•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 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.
•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 indoor unit 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.
•Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result
in refrigerant leakage.
•Wear heavy gloves during the installation work to avoid injury.
•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.

WARNING
•When the air conditioner cannot cool or heat a room well, contact the dealer from whom you
purchased the air conditioner as refrigerant leakage is considered as the cause.
In the case of repair that requires refill of refrigerant, ask service personnel about details of the
repair.
The refrigerant used in the air conditioner is harmless.
Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove
burner in the room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has
been completely repaired.
•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.
•Install the refrigerant pipe securely during the installation work before operating the air
conditioner.
If the compressor is operated with the valve open and without the refrigerant pipe, the compressor sucks
air and the refrigeration cycle is overpressurized, which may cause a burst or injury.
•For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop
the compressor before disconnecting the refrigerant pipe.
If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor
sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.
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 changed 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.
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 40 A (All type fuse can be used) must be used for the power supply line of this
conditioner.
3INSTALLATION OF NEW REFRIGERANT
AIR CONDITIONER
• The R410A refrigerant is more susceptible to impurities such as water, oxide membrane, oils, and fats.
With the adoption of the new refrigerant, refrigerating oil has also been changed.
Be careful so that water, dust, conventional refrigerant, and/or conventional refrigerating oil do not
enter the refrigerating cycle of the new refrigerant air conditioner.
• To prevent different refrigerant or refrigerating oil being mixed, the sizes of the charging port of the unit
and the installation tool connecting sections are different from the conventional refrigerant. Accordingly
the following exclusive tools are required for the new refrigerant R410A.

6AIR PURGING
Airtight test
Before starting an airtight test, further tighten the spindle valves on the gas side and liquid side.
Pressurize the pipe with nitrogen gas charged from the service port to the design pressure (4.15 Mpa) to
conduct the airtight test.
After the airtight test is completed, evacuate the nitrogen gas.
Air Purge
With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge
(Evacuate air in the connecting pipes) when installing the unit.
• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.
• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains,
the capacity may decrease.
For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump
does not backflow into the pipe of the air conditioner when the pump stops.
(If oil in the vacuum pump is put in an air conditioner including R410A, it may cause trouble on the
refrigeration cycle.)
Vacuum pump
*1Use the vacuum pump, vacuum pump adapter,
and gauge manifold correctly referring to the
manuals supplied with each tool before using
them.
Check that the vacuum pump oil is filled up to
the specified line of the oil gauge.
*2When air is not charged, check again whether
the connecting port of the discharge hose,
which has a projection to push the valve core, is
firmly connected to the charge port.
As shown in the figure, connect the charge hose after the
manifold valve are closed completely.
È
Attach the connecting port of the charge hose with a
projection to push the valve core (setting pin) to the charge
port of the set.
È
Open handle Low fully.
È
Turn ON the vacuum pump (*1)
È
Loosen the flare nut of the packed valve (Gas side) a little to
check the air passes through. (*2)
È
Tighten the flare nut again.
È
Execute vacuuming until the compound pressure gauge
indicates –101kPa (–76cmHg). (*1)
È
Close handle Low completely.
È
Turn OFF the vacuum pump.
È
Leave the vacuum pump as it is for 1 or 2 minutes, and check
the indicator of the compound pressure gauge does not
return.
È
Open fully the valve stem or the valve handle. (First, at liquid
side, then gas side)
È
È
Disconnect the charge hose from the charge port.
È
Tighten valve and caps of the charge port surely.

How to open the valve
Confirm the structure surely and then open or
close the valve.
▼Liquid side
Open the valve with a 4-mm hexagon wrench.
▼Gas side
• While the valve is fully opened, after the
screwdriver has reached the stopper, do not
apply torque exceeding 5N•m. Applying
excessive torque may damage the valve.
Valve handling precautions
• Open the valve stem until it strikes the stopper.
It is unnecessary to apply further force.
• Securely tighten the cap with a torque wrench.
• Cap tightening torque
Replenishing refrigerant
This model is a 30 m chargeless type that does
not need to replenish refrigerant for refrigerant
pipes up to 30 m. When a refrigerant pipe longer
than 30 m is used, add the specified amount of
refrigerant.
Refrigerant replenishing procedure
1. After the vacuuming of the refrigerant pipe is
completed, close the valves and then charge
refrigerant while the air conditioner is not
working.
2. When the refrigerant cannot be charged to the
specified amount, charge the required amount
of refrigerant from the charge port of the valve
on the gas side during cooling.
Requirement for replenishing
refrigerant
Replenish liquid refrigerant.
When gaseous refrigerant is replenished, the
refrigerant composition varies, which disables
normal operation.
Additional amount of refrigerant
• L: Pipe length
• For additional amount of refrigerant for twin
system and triple system, refer to the
installation manual supplied with the branching
pipe (sold separately).
• The refrigerant need not be reduced for a
30 meter (or less) refrigerant pipe.
