This mark means "Caution" or "Warning".
• • • • After installation work has been completed, do not only make sure that the unit is free from any abnormal condition through the
execution of trial 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.
The appliance must be installed by technician, who takes into
account the requirements given by ISO5149 or eventual
equivalent requirements.
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 leads to water leakage, electric
shock, fire, etc.
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.
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.
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.
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.
Wiring shall be connected using specified cables and fix them
securely so that external force of the cables may not transfer to

Warnings
If installing inside a small room, measures should be taken to
prevent refrigerant levels from building up to critical
concentrations in the event of a refrigerant leak occurring.
Please discuss with the place of purchase for advice on what
measures may be necessary to prevent critical concentrations
being exceeded. If the refrigerant leaks and reaches critical
concentration levels, there is the danger that death from
suffocation may result.
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.
Switch off all supplies before accessing any electrical part.
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.
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.
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.
