2 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.
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.

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.
3 INSTALLATION 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.

5 m to 30 m |
Addition of refrigerant is |
|
unnecessary at the local site. |
||
|
||
|
<Addition of refrigerant> |
|
*31 m to 50 m |
Add 40 g of refrigerant for |
|
every 1m of pipe which |
||
|
||
|
exceeds 30 m. |
*Caution at addition of refrigerant
When the total length of refrigerant pipe exceeds 30 m, add 40 g /m of refrigerant and the maximum total length of pipe is 50 m. (Max. amount of additional refrigerant is 800 g.) Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor.
*Do not connect a refrigerant pipe shorter than
5 m.
This may cause a malfunction of the compressor or other devices.
Airtight test
1.Before starting an airtight test, further tighten the spindle valves on the gas side and liquid side.
2.Pressurize the pipe with nitrogen gas charged from the service port to the design pressure (4.15 Mpa) to conduct the airtight test.
3.After the airtight test is completed, evacuate the nitrogen gas.
Air purge
•For air purge, use a vacuum pump.
•Do not use refrigerant charged in the outdoor unit for air purge. (The refrigerant for air purge is not contained in the outdoor unit.)
