SAFETY PRECAUTIONS
Read the following "SAFETY PRECAUTIONS" carefully before installation.
Electrical work must be installed by a licensed electrician. Be sure to
use the correct rating of the power plug and main circuit for the model
to be installed.
The caution items stated here must be followed because these important
contents are related to safety. The meaning of each indication used
is as below. Incorrect installation due to ignoring of the instruction will
cause harm or damage, and the seriousness is classified by the
following indications.
WARNING
1. Use qualified installer and follow careful this instructions, otherwise
it will cause electrical shock, water leakage, or aesthetic problem.
2. Install at a strong and firm location which is able to withstand the
set's weight. If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
3. For electrical work, follow the local national wiring standard, regulation
and this installation instruction. An independent circuit and single
outlet must be used. If electrical circuit capacity is not enough it
will cause electrical shock or fire.
4. Use the specified cable and connect tightly for indoor/outdoor
connection. Connect tightly and clamp the cable so that no external
force will be acted on the terminal.
If connection or fixing is not perfect, it will cause heat-up or fire at
the connection.
5. Wire routing must be properly arranged so that control board cover
is fixed properly. If control board cover is not fixed perfectly, it will
cause heat-up at connection point of terminal, fire or electrical
shock.

2. Do not release refrigerant during piping work for installation,
18 N m(1.8 kgf.m)
reinstallation and during repairing a refrigeration parts. Take
45 N m(4.5 kgf.m)
care of the liquid refrigerant, it may cause frostbite.
65 N m(6.5 kgf.m)
3. Installation work. It may need two people to carry out the
75 N m(7.5 kgf.m)
installation work.
85 N m(8.5 kgf.m)
4. Do not install this appliance in a laundry room or other location
where water may drip from the ceiling, etc.
Carry out test running to confirm that no abnormality occurs after the

The items to be followed are classified by the symbols:
6. When carrying out piping connection, take care not to let air
substances other than the specified refrigerant go into refrigeration
cycle, otherwise, it will cause lower capacity, abnormal high pressure
in the refrigeration cycle, explosion and injury.
7. Do not damage or use unspecified power supply cord.
Otherwise, it will cause fire or electrical shock.
8. Do not modify the length of the power supply cord or use of
the extension cord, and do not share the single outlet with other
