• Be sure to observe the warnings and cautions specified here as they include important items related to safety.
• After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS for future reference.
• Equipment complying with IEC/EN 61000-3-12.
WARNING
Do not install the unit by yourself (user).
N
Incomplete installation could cause fire or electric shock, injury due to the
unit falling, or leakage of water. Consult the dealer from whom you pur
chased the unit or a qualified installer.
Perform the installation securely referring to the installation manual.
N
Incomplete installation could cause fire or electric shock, injury due to the
unit falling, or leakage of water.
When installing the unit, use appropriate protective equipment and tools
N
for safety.
Failure to do so could cause injury.
Install the unit securely in a place which can bear the weight of the unit.
N
If the installation location cannot bear the weight of the unit, the unit
could fall causing injury.
Perform electrical work according to the installation manual and be
N
sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit.
If the capacity of the power circuit is insufficient or there is incomplete
electrical work, it could result in a fire or an electric shock.
Do not damage the wires by applying excessive pressure with parts
N
or screws.
Damaged wires could cause fire.
Be sure to cut off the main power in case of setting up the indoor P.C.
N
board or wiring works.
Failure to do so could cause electric shock.
Use the specified wires to connect the indoor and outdoor units se-
N
curely and attach the wires firmly to the terminal block connecting
sections so the stress of the wires is not applied to the sections.
Incomplete connecting and securing could cause fire.
Do not install the unit in a place where inflammable gas may leak.
N
If gas leaks and accumulates in the area around the unit, it could cause
an explosion.
Do not use intermediate connection of the power cord or the exten-
N
sion cord and do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defec-
tive insulation, exceeding the permissible current, etc.
Be sure to use the parts provided or specified parts for the installa-
N
tion work.
The use of defective parts could cause an injury or leakage of water due
to a fire, an electric shock, the unit falling, etc.
When plugging the power supply plug into the outlet, make sure
N
that there is no dust, clogging, or loose parts in both the outlet and
the plug. Make sure that the power supply plug is pushed completely into the outlet.
If there is dust, clogging, or loose parts on the power supply plug or the
outlet, it could cause electric shock or fire. If loose parts are found on the
power supply plug, replace it.
CAUTION
Install an earth leakage breaker depending on the installation place.
N
If an earth leakage breaker is not installed, it could cause electric shock.
Perform the drainage/piping work securely according to the installa-
N
tion manual.
If there is defect in the drainage/piping work, water could drop from the
unit, soaking and damaging household goods.
(Could lead to death, serious injury, etc.)
Attach the electrical cover to the indoor unit and the service panel
N
to the outdoor unit securely.
If the electrical cover of the indoor unit and/or the service panel of the
outdoor unit are not attached securely, it could result in a fire or an
electric shock due to dust, water, etc.
When installing, relocating, or servicing the unit, make sure that
N
no substance other than the specified refrigerant (R410A) enters
the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal
pressure rise and may result in explosion or injury. The use of any re
frigerant other than that specified for the system will cause mechanical
failure, system malfunction, or unit breakdown. In the worst case, this
could lead to a serious impediment to securing product safety.
Do not discharge the refrigerant into the atmosphere. If refrigerant
N
leaks during installation, ventilate the room.
If refrigerant comes in contact with a fire, harmful gas could be generated.
Refrigerant leakage may cause suffocation. Provide ventilation in accord
ance with EN378-1.
Check that the refrigerant gas does not leak after installation has
N
been completed.
If refrigerant gas leaks indoors, and comes into contact with the flame
of a fan heater, space heater, stove, etc., harmful substances will be
generated.
Use appropriate tools and piping materials for installation.
N
The pressure of R410A is 1.6 times more than R22. Not using appropri-
ate tools or materials and incomplete installation could cause the pipes
to burst or injury.
When pumping down the refrigerant, stop the compressor before
N
disconnecting the refrigerant pipes.
If the refrigerant pipes are disconnected while the compressor is run-
ning and the stop valve is open, air could be drawn in and the pressure
in the refrigeration cycle could become abnormally high. This could
cause the pipes to burst or injury.
When installing the unit, securely connect the refrigerant pipes
N
before starting the compressor.
If the compressor is started before the refrigerant pipes are connected
and when the stop valve is open, air could be drawn in and the pressure
in
the refrigeration cycle could become abnormally high. This
could cause the pipes to burst or injury.
Fasten a flare nut with a torque wrench as specified in this manual.
N
If fastened too tight, a flare nut may break after a long period and cause
refrigerant leakage.
The unit shall be installed in accordance with national wiring regu-
N
lations.
Earth the unit correctly.
N
Do not connect the earth to a gas pipe, water pipe, lightning rod or tel-
ephone earth. Defective earthing could cause electric shock.
(Could lead to serious injury in particular environments when operated incorrectly.)
Do not touch the air inlet or the aluminum fins of the outdoor unit.
N
This could cause injury.
Do not install the outdoor unit where small animals may live.
N
If small animals enter and touch the electric parts inside the unit, it
could cause a malfunction, smoke emission, or fire. Also, advise user
to keep the area around the unit clean.
