1.1 Safety cautions

WARNING

This symbol indicates the possibility of personnel injury or loss of life.

Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system
ressures, electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start-up, and serve this equipment.
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels
attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher
nearby when brazing. Use care in handing, rigging, and setting bulky equipment.
Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to
the unit. Consult local building codes and National Electrical Code for special requirement.

Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen
depletion, especially in basements, and an asphyxiation hazard could occur leading to serious
injury or death.
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.
If the refrigerant gas leaks during installation, ventilate the area immediately.

Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove
or cooking device.
Exposure to this gas could cause severe injury or death.

Disconnect from power source before attempting any electrical work. Connect the connective cable
correctly.

Wrongly connecting may result in electric parts damaged.

Use the specified cables for electrical connections and attach the wires firmly to the terminal block
connecting sections so that the external force is not exerted to the terminal.
Be sure to provide grounding.

Do not ground units to gas pipes, water pipes, lightning rods or telephone wires. Incomplete grounding could cause a severe
shock hazard resulting in injury or death.

Safely dispose of the packing materials.

Packing materials, such as nails and other matal or wooden parts, may cause stabs or other injuries. Tear apart and throw away
plastic pacaging bags so that children will not play with them. Children playing with plastic bags face the danger of suffocation.

Do not install unit near concentrations of combustible gas or gas vapors.
Be sure to use the supplied or exact specified installation parts.

Use of other parts may cause the unit to come to lose, water leakage, electrical shock, fire or equipment damage.

When installing or relocating the system, do not allow air or any substances other than the
specified refrigerant (R410A) to enter the refrigeration cycle.
Duct and Cassette type indoor is not accessible to the general public and intended to be

maintained by qualified service personnel and located at a level not less than 2.5m from floor.

Electrical work should be carried out in accordance with the installation manual and the national,
state and local electrical wiring codes.
Be sure to use a delicated power circuit. Never share the same power outlet with other appliance.

1. PREPARING FOR INSTALLATION

WARNING

CAUTION

This symbol indicates the possibility of property damage or serious consequences.

WARNING

Never modify this unit by removing any of the safety guards or bypassing any of the safety
interlock switches.
In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must
not be supplied through an external switching device, such as a timer, or connected to a circuit
that is regularly switched on and off by the utility.
Use the prescribed cables for electrical connection with insulation protected by insulation
sleeving having an appropriate temperature rating.

Unconformable cables can cause electric leak, anomalous heat prodcution or fire.

To avoid personal injury, be careful when handling parts with sharp edges.
Do not install the indoor or outdoor units in a location with special environmental conditions.
Do not install in a place that can amplify the noise level of the unit or where noise and discharged
air might disturb neighbors.
Perform the drainage/piping work securely according to the installation manual.

Improper drain piping may result in water leakage and property damage.

Do not instal the air conditioner in the following places.

-The place where there is mineral oil or arsenic acid.

-The place where corrosive gas (such as sulfurous acid gas) or combustible gas (such as thinner)
can accumulate or collect, or where volatile combustible substances are handled.

-The place there is equipment that generates electromagnetic fields or high frequencey harmonics.

This product contains fluorinated gases covered by the Kyoto Protocol

CAUTION

1. Paste the enclosed refrigerant label adjacent to the
charging and/or recovering location.

2. Clearly write the charged refrigerant quantity on
the refrigerant label using indelible ink.

3. Prevent emission of the contained fluorinated gas.
Ensure that the fluorinated gas is never vented to
the atmosphere during installation, service or
disposal. When any leakage of the contained
fluorinated gas is detected, the leak shall be
stopped and repaired as soon as possible.

4. Only qualified service personnel are allowed to
access and service this product.

5. Any handling of the fluorinated gas in this product,
such as when moving the product or recharging the
gas, shall comply under (EC) Regulation No. 842/
2006 on certain fluorinated greenhouse gases and
any relevant local legislation.

6. Contact dealers, installers, etc., for any questions.
