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.

ENGLISH

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.

PRECAUTIONS FOR SAFETY

• 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

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.

REFRIGERANT PIPING

WARNING

• 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 may

generate.

REQUIREMENT

When the refrigerant pipe is long, set the support brackets to fix the pipe with 2.5 to 3m intervals. If the pipe is not fixed, abnormal sound may generate.

Be sure to use the flare nuts attached to the indoor unit or those for R410A.

Permissible pipe length and permissible height difference

• Be sure to use a double spanner for pipe connecting work of the indoor unit.

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.

Protective device operation

2. Special mention

1) If this model is connected to AI-NET by network adaptor, the different check codes are displayed on the main remote controller (New check code display on new remote controller) and AI-NET central control remote controller (Current system check code display on the current system central control remote controller).

2) The check code is displayed only while the air conditioner is operating (Remote controller start button ON). When the air conditioner stops and the error is cleared, the check code display on the remote controller also

disappears. However, if the error continues after stop of the operation, the check code is immediately displayed with restarting.
