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 FEATURES A NEW HFC REFRIGERANT (R410A) WHICH DOES NOT
DEPLETE OZONE LAYER.
The pressure of R410A is 1.6 times higher than that of former refrigerant R22.
The refrigerating oil has also been changed. Therefore be sure that any former refrigerant, refrigerant oil or any
other contaminants do not enter the refrigerating cycle of the air conditioner, during either installation or service
work. If incorrect tools or operating procedures are used, there is a possibility of a serious accident.
Use only tools and materials that have been designed to operate with R410A.
To prevent the risk of charging with an incorrect refrigerant, the dimensions of the charging port connections
are different to those used for conventional refrigerant.
Therefore only tools designed to operate with R410A can be used.
For connecting pipes, use piping specifically designed for R410A.
During installation, ensure pipes are clean and ensure contaminants do not enter the pipes as the system is
affected by impurities such as water, oxide scales, dirt, oil, etc. Do not use existing pipe work from previous
installation as this will cause problems due to pressure resistances and impurities within the pipe.
CAUTION To Disconnect the Appliance from Main Power Supply.
A switch or circuit breaker that can disconnect all poles must be included in the fixed wiring.
Be sure to use an approved circuit breaker or switch.
The installation fuse 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 an electric shock.
•Connect all of the installation wiring correctly.
If the installation wiring is incorrect electrical parts may be damaged.
•During the transportation and installation of the air conditioning unit, ensure that gaseous matter
other than the specified refrigerant does not enter into the refrigeration cycle.
If a refrigerant becomes contaminated with foreign gases, the gas pressure within the refrigerant cycle will
become abnormally high and may result in the fracture of pipework and possible human injury.
•Do not modify this unit by removing any of the safety guards or by overriding any of the safety
interlock switches.
•Exposure of the unit to water or other forms of moisture before installation may cause a short-
circuit of the electrical parts.
Do not store it in a wet basement or expose to rain or water.
ENGLISH

•After unpacking the unit, examine for 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.
Incorrect installation may result in water leakage, electric shock or a fire.
•When the air conditioner is installed in a small room, provide appropriate measures to ensure
that in the event of a refrigerant leak the rooms does not exceed the critical level.
•Install the air conditioner securely in a location where the base can sustain the weight of the unit
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 unit falling.
•If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gases may be generated.
•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 gases
maybe generated.
•Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual. Ensure the power supply to the air conditioner is exclusive to that unit only.
An insufficient power supply capacity or inappropriate installation may cause fire.
•Use only the specified wiring during the unit installation. Ensure that all terminals are securely
fixed, so preventing any external forces having a negative effect on the terminals.
•Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
•Conform to the regulations of the local electric authority when wiring the power supply.
Inappropriate grounding may cause an electric shock.
•Do not install the air conditioner in a location that maybe subjected to a risk of exposure to a
combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

5REFRIGERANT 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.
3. Flare nut and flare works are 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.
•Projection margin in flaring :

•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.

6EVACUATING
AIR PURGE
Evacuate the air in the connecting pipes and in
the indoor unit using vacuum pump.
Do not use the refrigerant in the outdoor unit.
For details, see the manual of vacuum pump.
Use a vacuum pump
Be sure to use a vacuum pump with counter-flow
prevention function so that inside oil of the pump does
not flow backward into pipes of the air conditioner
when the pump stops.
1. Connect the charge hose from the manifold valve
to the service port of the gas side packed valve.
2. Connect the charge hose to the port of vacuum
pump.
3. Open fully the low pressure side handle of the
gauge manifold valve.

Perform evacuating for about 35 minutes if the
piping length is total 70 meters.
(25 minutes for total 50 meters)
(assuming a pump capacity of 27 liters per
minute.)
Then confirm that the compound pressure gauge
reading is –101 kPa ( –76 cmHg).
5. Close the low pressure side valve handle of gauge
manifold.
6. Open fully the valve stem of the packed valves
(both sides of Gas and Liquid).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
