SAFETY
PRECAUTIONS
•
Before installation, read the “SAFETY
PRECAUTIONS” carefully and strictly follow it during the installa
-
tion work in order to protect yourself.
•
The precautionary items mentioned below are distinguished into two levels,
W
ARNING
and
CAUTION
.
W
ARNING
Indicates
a potentially
hazardous
situation
which, if not avoided,
can result
in serious
con
-
sequences such as death or severe injury
.
CAUTION
Indicates
a potentially
hazardous
situation
which, if not avoided,
can
result
in personal
in
-
jury or property damage.
Both mention the important items to protect your health and safety
. Therefore, strictly follow them by any means.
•
Be
sure
to
confirm
no
operation
problem
on
the
equipment
after
completing
the
installation.
If
unusual
noise can be heard during the test run, consult the dealer
.
•
Be sure to explain the operating methods as well as the maintenance
methods of this equipment to
the
user according to the user
’s manual.
•
Be sure to
keep the installation manual together with user
’s
manual at
a place where it is easily accessi
-
ble to the user any time. Moreover
, ask the user to hand the manuals to a new user
, whenever required.
W
ARNING
•
Be sure to use only for residential purpose.
If this unit is installed
in inferior environment
such as machine
shop, vehicle
(like ship), warehouse,
etc., it can malfunction.
•
Installation
must
be
carried
out
by
the
qualified
installer
completely
in
accor
-
dance with the installation manual.
Installation
by
non
qualified
person
or
incorrect
installation
can
cause
serious
troubles
such
as
water
leak,
electric
shock,
fire
and
personal
injury
.
•
Be sure to wear protective goggles and gloves while performing installation work.
Improper
safety
measures
can
result
in
personal
injury
.
•
Use
the
original
accessories
and
the
specified
components
for
the
installation.
Using
parts
other
than
those
prescribed
may
cause
water
leak,
electric
shock,
fire
and
personal
injury
.
•
Do
not
install
the
unit
near
the
location
where
leakage
of
flammable
gases
can
occur
.
If
leaked
gases
accumulate
around
the
unit,
it
can
cause
fire
resulting
in
property
damage
and
per
-
sonal
injury
.
•
When installing the unit in small rooms, make sure that refrigerant density does not exceed the limit (Reference: ISO5149) in the event of leakage.
If refrigerant density exceeds the limit, consult the dealer and install the ventilation system. Otherwise lack of oxygen can occur resulting in serious accident.
•
Install
the
unit
in
a location
where
unit
will
remain stable,
horizontal
and
free
of any vibration transmission.
Unsuitable
installation
location
can
cause
the
unit
to
fall
resulting
in
material
damage
and
personal
injury
.
•
Do not run the unit with removed panels or protections.
Touching
rotating
equipments,
hot
surfaces
or
high
voltage
parts
can
cause
personal
injury
due
to
entrapment, burn or electric shock.
•
This
unit
is
designed
specifically
for
R410A.
Using
any
other
refrigerant
can
cause
unit
failure
and
personal
injury
.
•
Do
not
vent
R410A
into
atmosphere.
R410A
is
a
fluorinated
greenhouse
gas
with
a
Global
W
arning
Potential(GWP)=2088.
•
Make sure that no air enters the refrigerant circuit when
the unit
is installed
and removed.
If air enters the
refrigerant
circuit,
the
pressure
in
the
refrigerant
circuit
will
become
too
high,
which
can
cause
burst
and
personal
injury
.
•
Be
sure
to
use
the
prescribed
pipes,
flare
nuts
and
tools
for
R410A.
Using
existing
parts
(for
R22
or
R407C)
can
cause
refrigerant
circuit
burst
resulting
in
unit
failure
and
personal
injury
.
•
Be sure
to
connect both
liquid
and
gas
connecting
pipes
properly
before op
-
erating the compressor
.

and evacuation.
If the compressor is operated when connectin
g pipes are not connected
and service
valves
are open,
air
can be sucked
into the refrigerant
circuit
which
can cause
anomalous high pressure resulting
in
burst
or
personal
injury
.
•
Be
sure
to
tighten
the
flare
nuts
to
specified
torque
using
the
torque
wrench.
Tightening
flare
nuts
with
excess
torque
can
cause
burst
and
refrigerant
leakage
after
a
long
period.
•
During
pump
down
work,
be sure to
stop
the compressor before closing
ser
-
vice valves and removing connecting pipes.
If the connecting pipes ar
e removed w
hen the compressor
is in oper
ation and service valves are
open, air can be sucked into the refrigerant circuit which can cause anomalous high pressure result
-
ing
in
burst
or
personal
injury
.
•
In the event of refrigerant leakage during
installation,
be sure to ventilate the
working area properly
.
If
the
refrigerant
comes
into
contact
with
naked
flames,
poisonous
gases
will
be
produced.
•
Electrical
work
must
be
carried
out
by
the
qualified
electrician,
strictly
in
ac
-
cordance with national or regional electricity regulations.
Incorrect
installation
can
cause
electric
shock,
fire
or
personal
injury
.
•
Make sure that earth leakage breaker and circuit breaker of appropriate ca
-
pacities are installed.
Circuit
breaker
should
be
able
to
disconnect
all
poles
under
over
current.
Absence
of
appropriate
breakers
can
cause
electric
shock,
personal
injury
or
property
damage.
•
Be
sure
to
switch off
the power
source in the event
of
installation,
mainte
-
nance or service.
If
the
power
source
is
not
switched
of
f,
there
is
a
risk
of
electric
shock,
unit
failure
or
personal
injury
.

•
Be sure to
clamp
the
cables properly
so
that
they
do
not
touch
any
internal
component of the unit.
If
cables
touch
any
internal
component,
it
can
cause
overheating
and
fire.
•
Be sure to install service cover properly
.
Improper
installation
can
cause
electric
shock
or
fire
due
to
intrusion
of
dust
or
water
.
•
Be sure to use the prescribed power and connecting cables for electrical work.
Using
improper
cables
can
cause
electric
leak,
anomalous
heat
production
or
fire.
•
This appliance must be connected to main power source by means of a cir
-
cuit breaker or switch with a contact separation of at least 3mm.
