CAUTION

• Use the circuit breaker with sufficient breaking capacity.

If the breaker does not have sufficient breaking capacity, it can cause

the unit malfunction and fire.

• Earth leakage breaker must be installed.

If the earth leakage breaker is not installed, it can cause electric

shocks.

• Install isolator or disconnect switch on the power supply wiring

in accordance with the local codes and regulations.

• After maintenance, all wiring, wiring ties and the like, should be

returned to their original state and wiring route, and the

necessary clearance from all metal parts should be secured.

• Secure a space for installation, inspection and maintenance

specified in the manual.

Insufficient space can result in accident such as personal injury due to

falling from the installation place.

• Take care when carrying the unit by hand.

If the unit weights more than 20kg, it must be carried by two or more

persons. Do not carry by the plastic straps, always use the carry

handle when carrying the unit by hand. Use gloves to minimize the risk

of cuts by the aluminum fins.

• Dispose of any packing materials correctly.

Any remaining packing materials can cause personal injury as it

contains nails and wood. And to avoid danger of suffocation, be sure

to keep the plastic wrapper away from children and to dispose after

tear it up.

• Be sure to insulate the refrigerant pipes so as not to condense

the ambient air moisture on them.

Insufficient insulation can cause condensation, which can lead to

moisture damage on the ceiling, floor, furniture and any other

valuables.

• When perform the air conditioner operation (cooling or drying

operation) in which ventilator is installed in the room. In this

case, using the air conditioner in parallel with the ventilator,

there is the possibility that drain water may backflow in

accordance with the room lapse into the negative pressure

status. Therefore, set up the opening port such as incorporate

the air into the room that may appropriate to ventilation (For

example; Open the door a little). In addition, just as above, so

set up the opening port if the room lapse into negative

pressure status due to register of the wind for the high rise

apartment etc.

• Do not install the unit in the locations listed below.

• Locations where carbon fiber, metal powder or any powder is floating.

• Locations where any substances that can affect the unit such as

sulphide gas, chloride gas, acid and alkaline can occur.

• Vehicles and ships.

• Locations where cosmetic or special sprays are often used.

• Locations with direct exposure of oil mist and steam such as kitchen

and machine plant.

• Locations where any machines which generate high frequency

harmonics are used.

• Locations with salty atmospheres such as coastlines.

• Locations with heavy snow (If installed, be sure to provide base

flame and snow hood mentioned in the manual).

• Locations where the unit is exposed to chimney smoke.

• Locations at high altitude (more than 1000m high).

• Locations with ammonic atmospheres.

• Locations where heat radiation from other heat source can affect the

unit.

• Locations without good air circulation.

• Locations with any obstacles which can prevent inlet and outlet air

of the unit.

• Locations where short circuit of air can occur (in case of multiple

units installation).

• Locations where strong air blows against the air outlet of outdoor

unit.

It can cause remarkable decrease in performance, corrosion and

damage of components, malfunction and fire.

• Do not install the outdoor unit in the locations listed below.

• Locations where discharged hot air or operating sound of the

outdoor unit can bother neighborhood.

• Locations where outlet air of the outdoor unit blows directly to

plants.

• Locations where vibration can be amplified and transmitted due to

insufficient strength of structure.

• Locations where vibration and operation sound generated by the

outdoor unit can affect seriously (on the wall or at the place near bed

room).

• Locations where an equipment affected by high harmonics is placed

(TV set or radio receiver is placed within 5m).

• Locations where drainage cannot run off safely.

It can affect surrounding environment and cause a claim.

• Do not install the unit near the location where leakage of

combustible gases can occur.

If leaked gases accumulate around the unit, it can cause fire.

• Do not install the unit where corrosive gas (such as sulfurous

acid gas etc.) or combustible gas (such as thinner and

petroleum gases) can accumulate or collect, or where volatile

combustible substances are handled.

Corrosive gas can cause corrosion of heat exchanger, breakage of

plastic parts and etc. And combustible gas can cause fire.

• Do not install nor use the system close to the equipment that

generates electromagnetic fields or high frequency harmonics.

Equipment such as inverters, standby generators, medical high

frequency equipments and telecommunication equipments can affect

the system, and cause malfunctions and breakdowns. The system

can also affect medical equipment and telecommunication equipment,

and obstruct its function or cause jamming.

• Do not install the outdoor unit in a location where insects and

small animals can inhabit.

Insects and small animals can enter the electric parts and cause

damage or fire. Instruct the user to keep the surroundings clean.

• Do not use the base flame for outdoor unit which is corroded

or damaged due to long periods of operation.

Using an old and damage base flame can cause the unit falling down

and cause personal injury.

• Do not use any materials other than a fuse with the correct

rating in the location where fuses are to be used.

Connecting the circuit with copper wire or other metal thread can

cause unit failure and fire.

• Do not touch any buttons with wet hands.

It can cause electric shocks.

• Do not touch any refrigerant pipes with your hands when the

system is in operation.

During operation the refrigerant pipes become extremely hot or

extremely cold depending the operating condition, and it can cause

burn injury or frost injury.

• Do not touch the suction or aluminum fin on the outdoor unit.

This may cause injury.

• Do not put anything on the outdoor unit and operating unit.

This may cause damage the objects or injury due to falling to the

object.

Accessories for outdoor unit

• Model name and power source

• Refrigerant piping length

• Piping, wiring and miscellaneous small parts

• Indoor unit installation manual
