1. PRECAUTIONS
To prevent injury to the user or other people and property
damage, the following instructions must be followed. Incorrect
operation due to ignoring of instructions may cause harm or
damage. The appliance should be installed by a professional in
accordance with the specified instructions.
The safety precautions listed here are divided into two categories. In
either case, important safety informations are listed which must be
read carefully.
WARNING
Failure to observe a warning may cause electric shock,
fire hazard or personal injury
CAUTION
Failure to observe a caution may cause injury or damage
to the equipment.
WARNING
● Ask your dealer or qualified personnel to carry out installation
work. Do not try to install the machine by. Incorrect installation
may result in leakage, electric shocks or fire.
● Installation should be done by following the installation manual
and no changes should be made to the unit. Incorrect installation
may cause leakage, electric shock, or fire. If the KRE falls, it may
cause damage and injury.
● Install the unit on a foundation that is strong enough to withstand
the weight of the unit.
A foundation of insufficient strength may result in the equipment
falling and causing injuries.
● Do not allow exhaust air to enter the outside air inlet.
This may cause the air of the room to become contaminated,
harming the health.
● Locate the outside air intake vent so that it does not take in
exhaust air which contains combustion air, etc.
Incorrect installation may cause a loss of oxygen in the room,
leading to serious accidents.
● Make sure that a separate power supply circuit is provided for
this unit and that all electrical work is carried out by qualified
personnel according to local laws and regulations and this instal-
lation manual.
Insufficient power capacity, improper electrical works, or incorrect
wiring may cause electric shock or fire.
● Make sure Earth Leakage Breaker is the type of all poles drop-out.
● Be sure to ground.
Do not connect the ground wire to gas or water pipes, lightning rod
or a telephone ground wire.
Incomplete grounding may result in electric shocks.
● Make sure that all wiring is secured, the specified wires are used,
and no external forces act on the terminal connections or wires.
Improper connections or installation may result in overheating or
fore.
● When wiring the power supply and connecting the remote control-
ler wiring and transmission wiring, position the wires so that the
electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in
electric shocks, fire or the terminals overheating.
CAUTION
● Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks.
● Install the indoor and outdoor units, power supply wiring and
connecting wires at least 1 meter away from television or radio
in order to prevent image interference or noise. (Depending on
the radio waves, a distance of 1 meter may not be sufficient
enough to eliminate the noise.)
● Install the two outdoor ducts with down slope to prevent rainwa-
ter from entering the unit.
If this is not done completely, water may enter the building, may
damage furniture, etc.
● Insulate the duct and the wall electrically when a metal duct is to
be penetrated through the metal lattice and wire lattice or metal
lining of a wooden structure wall.
Improper duct work may cause electric shocks or short circuits.
● Make sure that a snow protection measure is taken. If no pro-
tection snow may enter through the outdoor ducts, and cause
damaging furniture and electric shock and fire.
