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
-

, 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
personal
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 operating the compressor
.

and evacuation.
If the compressor is operated when connecting 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 service valves and removing connecting pipes.
If the connecting pipes are removed when the compressor is in operation 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 tighten the cables securely in terminal block and relieve the cables properly to prevent overloading the terminal blocks.
Loose
connections
or
cable
mountings
can
cause
anomalous
heat
production
or
fire.
•
Do not process, splice or modify the power cable, or share the socket with other power plugs.
Improper
power
cable
or
power
plug
can
cause
fire
or
electric
shock
due
to
poor
connection,
insuf
-
ficient
insulation
or
over-current.
•
Do not perform any change in protective device or its setup condition yourself.
Changing
protective
device
specifications
can
cause
electric
shock,
fire
or
burst.
•
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.
Improper
electrical
work
