●
Installation must be carried out by the qualified installer
.
If
you
install
the
system
by
yourself,
it
may
cause
serious
trouble
such
as
wa
ter
leaks,
electric
shocks,
fire
and
personal
injur
y,
as
a
result
of
a
system
malfunction.
●
Install the system in full accordance with the instruction manual. Incorrect installa
tion may cause bursts,
personal injur
y,
wa
ter leaks,
electric shocks and fire.
●
Use the original accessories and the specified components for installation. If
parts
other
than
those
prescribed
by
us
are
used,
It
may
cause
fall
of
the
unit,
w
a
ter
leaks,
electric
shocks,
fire,
refrigerant
leak,
substandard
performance,
control failure and personal injur
y.
●
When
installing
in
small
rooms,
take
prevention
measures
not
to
e
xceed
the
density
limit
of
refrigerant in
the
event
of
leakage
accordance with ISO5149. Consult
the
expert
about
p
revention
measures.
If
the
d
ensity
of
refrigerant
exceeds
the
limit
in
the
event
of
leaka
g
e,
lack
of
oxygen
can
occur
,
which
can
cause serious accidents.
●
V
entilate the working area well in the event of refrigerant leakage during installation.
If the refrigerant comes into contact with naked flames,
poisonous gas is produced.
●
After completed installation,
check that no refrigerant leaks from the system.
If refrigerant leaks into the room and comes into contact with an oven or other hot surface,
poisonous gas is produced.
●
Hang
up
the
unit
at
the
specified
points
with
ropes
which
can
support
the
weight
in
lifting
for
portage.
And
to
avoid
jolting
out
of
alignment,
be sure to hang up the unit at 4-point support. An improper manner of porta
ge such as 3-point support can cause dea
th or serious personal injur
y due to falling of the unit
●
Install the unit in a location with good support. Unsuitable installa
tion loca
tions can cause the unit to fall and cause ma
terial dama
ge and personal injur
y.
●
Ensure the unit is stable when installed,
so that it can withstand earthquakes and strong winds.
Unsuitable installa
tion loca
tions can cause the unit to fall and cause ma
terial dama
ge and personal injur
y.
●
The
electrical
installation
must
be
carried
out
by
the
qualified
electrician
in
accordance
with “the
norm
for
electrical
work”
and “national
wiring regulation”,
and the system must be connected to the dedicated circuit.
P
o
wer supply with insufficient ca
pacity and incorrect function done by improper work can cause electric shocks and fire,
●
Be sure to shut off the power before starting electrical work. Failure to shut off the po
wer can cause electric shocks,
unit failure or incorrect function of equipment.
●
Be sure to use the cables conformed to safety standard and cable ampacity for power distribution work. Unconformable cables can cause electric leak,
anomalous hea
t production or fire.
●
Use
the
prescribed
cables
for
electrical
connection,
tighten
the
cables
securely
in
terminal
block
and
relieve
the
cables
correctly
to
prevent
o
verloading the terminal blocks.
Loose connections or cable mountings can cause anomalous hea
t production or fire.
●
Arrange the wiring in the control box so that it cannot be pushed up further into the box.
Install the ser
vice panel correctly
.
Incorrect installa
tion may result in overhea
ting and fire.
●
Do not perform brazing work in the airtight room It can cause lack of oxygen.
●
Use the prescribed pipes,
fl
are nuts and tools for R410A.
Using existing parts (for R22 or R407C) can cause the unit failure and serious accidents due to burst of the refrigerant circui
t.
●
T
ighten
the
fl

by
using
double
spanners
and
tor
que
wrench
according
to
prescribed
method.
B

e
o
n
the
flare
part
by
tightening
with
excess
torque
can
cause

outflo
w
and
air
can
be
sucked
into
refrigerant
circuit,
which
can
cause
burst or personal injur
y
due to anomalously high pressure in the refrigerant
●
Only use prescribed optional parts.
The installation must be carried out by the qualified installer
.
If you install the system by yourself,
it can cause serious trouble such as wa
ter leaks,
electric shocks,
fire.
●
Do not perform an
y change of protective device itself or its setup condition

tion
by
short-circuiting
protective
device
of
pressure
s
witch
and
tempera
ture
controller
or
the
use
of
non
specified component can cause fire or burst.
●
Be sure to switch off the power supply in the event of installation,
inspection or ser
vicing.
If the po
wer supply is
not shut off,
there is a risk of electric shocks,
unit failure or personal
injur
y
due to the unexpected
star
t of fan.
●
Consult the dealer or an e
xpert regarding remo
v
al of the unit.
Incorrect installa
tion can cause wa
ter leaks,
electric shocks or fire.
●
Stop the compressor before c
losing
v
alve and disconnecting refrigerant pipes in case of pump down operation.
If
disconnecting
refrigerant
pipes
in
sta
te
of
opening
ser
vice
valves
before
compressor
stopping,
you
may
incur

outflo
w
and
air
can
be
sucked,
which
can
cause
burst
or
personal
injur
y
due
to
anomalously
high pressure in the refrigerant circuit
●
Ensure that no air enters in the refrigerant circuit when the unit is installed and remo
ved.
If
air
enters
in
the
refrigerant
circuit,
the
pressure
in
the
refrigerant
circuit
becomes
too
high,
which
can
cause
burst
and
personal injur
y.
●
Do not run the unit with remo
ved panels or protections
T
ouching
rota
ting
equipments,
hot
surfaces
or
high
volta
ge
parts
can
cause
personal
injur
y
due
to
entra
pment,
burn
or
electric
shocks.
●
Be sure to fix up the ser
vice panels.
Incorrect fixing can cause electric shocks or fire due to intrusion of dust or wa
ter
.
●
Do not perform an
y repairs or modifications by yourself.
Consult the dealer if the unit requires repair
.
If you repair or modify the unit,
it can cause wa
ter leaks,
electric shocks or fire.
