becomes too high, which can cause burst and personal injury.
• Do not processing, splice the power cord, or share a socket with other power plugs.
This may cause fire or electric shock due to defecting contact, defecting insulation
and over-current etc.
• Carry out the electrical work for ground lead with care.
Do not connect the ground lead to the gas line, water line, lightning conductor or telephone line's ground lead. Incorrect grounding can cause unit faults such as electric shocks due to short-circuiting.
• Use the circuit breaker for all pole correct capacity. Circuit breaker
should be the one that disconnect all poles under over current.
Using the incorrect circuit breaker, it can cause the unit malfunction and fire.
• Install isolator or disconnect switch on the power source wiring in
accordance with the local codes and regulations.
The isolator should be locked in OFF state in accordance with EN60204-1.
• 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.
• 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. (e.g. organic fertilizer)
• Locations with calcium chloride (e.g. snow melting agent).
• 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.
• Locations where something located above the unit could fall.
It can cause remarkable decrease in performance, corrosion and damage of
components, malfunction and fire.
Notabilia as a unit designed for R410A
●
Do not use any refrigerant other than R410A. R410A will rise to pressure about 1.6 times higher than that of a conventional refrigerant.
A cylinder containing R410A has a pink indication mark on the top.
●
A unit designed for R410A has adopted a different size indoor unit service valve charge port and a different size check joint provided in the unit to prevent the charging of a wrong refrigerant by mistake.
The processed dimension of the flared part of a refrigerant pipe and a flare nut's parallel side measurement have also been altered to raise strength against pressure.
Accordingly, you are required to arrange dedicated R410A tools listed in the table on the left before installing or servicing this unit.
●
Do not use a charge cylinder. The use of a charge cylinder will cause the refrigerant composition to change, which results in performance degradation.
●
In charging refrigerant, always take it out from a cylinder in the liquid phase.
●
All indoor units must be models designed exclusively for R410A. Check connectable indoor unit models in a catalog, etc. (A wrong indoor unit, if connected into the system, will impair proper system operation)

1. HAULAGE AND INSTALLATION
• Do not run the unit with removed panels or protections.
Touching rotating equipments, hot surfaces or high voltage parts can cause
personal injury due to entrapment, burn or electric shocks.
CAUTION
• 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.
• 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 an animal or
plants. The outlet air can affect adversely to the plant etc.
• 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.

(Take particular care in car rying in or moving the unit, and always pe rform such an operation with two or more persons.)
• 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 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.
• Do not use the unit for special purposes such as storing foods, cooling
precision instruments and preservation of animals, plants or art.
• Do not clean up the unit with water.
