Precautions in terms of safety
Carry out installation work with reliability after thorough reading of this “Precautions in terms of safety”.
•
Precautions shown here are differentiated between
Warnings and Cautions . Those that have much chances for
leading to significant result such as fatality or serious injury if wrong installation would have been carried out are listed compiling
them especially into the column of
Warnings .
However, even in the case of items which are listed in the column of
Cautions , such items also have a chance for leading
to significant result depending on the situations.
In either case, important descriptions regarding the safety are listed, then observe them without fail.

As to indications with illustration
•
After installation work has been completed, do not only make sure that the unit is free from any abnormal condition through the
execution of try run but also explain how to use and how to perform maintenance of this unit to the customer according to the
instruction manual.
In addition, request the customer to keep this manual for installation work together with instruction manual.
Warnings
The appliance must be installed by technician, who takes into
account the requirements given by ISO5149 or eventual
equivalent requirements.
Securely attach the protective covers for the outdoor unit
connection cables and power cord so that they do not lift up after
installation. If the covers are not properly attached and installed,
the terminal connections may overheat, and fire or electric shock
may result.
As to installation, request the distributor or vendor to perform it.
Imperfection in installation caused by that having been carried
out by the customer himself may lead to water leakage, electric
shock, fire, etc.
Switch off all supplies before accessing any electrical part.
Carry out the installation work with reliability according to this
manual for installation work.
Imperfection in installation leads to water leakage, electric
shock, fire, etc.
If refrigerant gas escapes during installation, ventilate the
affected area. If the refrigerant gas comes into contact with
sparks or naked flames, it will cause toxic gases to be generated.
Carry out the installation work with reliability on the place that
can bear the weight of this unit sufficiently. Insufficient strength
leads to injury due to falling of the unit.
Once installation work is completed, check that there are no
refrigerant gas in the room that can come into contact with sparks
or flames from a fan heater, stove or kitchen range, which will
cause toxic gases to be generated.
Carry out predetermined installation work in preparation for
strong wind such as typhoon, earthquake. Imperfection in
installation work may lead to accidents arisen from overturn, etc.
When performing piping work do not mix air except for specified
refrigerant (R410A) in refrigeration cycle. It causes capacity
down, and risk of explosion and injury due to high tension inside
the refrigerant cycle.
The unit must be installed in accordance with applicable national
and local regulations.
Any electrical work should only be carried out by qualified
technician and use exclusive circuits without fail.
Presence of insufficient capacity in power circuit or imperfection
in execution leads to electric shock, fire, etc.
Earth
This equipment must be properly earthed.
Earth line must not be connected to earth of gas
pipe, water pipe, lightning rod and telephone.
Otherwise, it may cause electrical shock in case
the equipment breakdown or has leakage current.
Wiring shall be connected securely using specified cables and
fix them securely so that external force of the cables may not
transfer to the terminal connection section.
Imperfect connection and fixing leads to fire, etc.
Installation of Earth Leakage Current Breaker
This equipment must be installed with earth leakage current
breaker.
Otherwise, it may cause electrical shock and fire in case the
equipment breakdown or has leakage current.
