● Do
not
perform
installation
work,
refrigerant
piping
work,
condensate
pump,
or
condensate
piping
and
electrical
wiring
connection
without
referring
to
the
installation
manual.
If
the
instructions
are
not
followed,
it
may
result
in
a
water
leakage,
electric
shock
or
a
fire
●
Use the specified non-
fla
mm
able refrigerant (R410A) for the outdoor unit in the refrigerant cycle.
Charge
only R410A into the unit. Do not charge other materials into the unit such as hydrocarbon
refrigerants
(propane), oxygen, flammable gases (acetylene) or poisonous gases when installing,
maintaining and
moving the unit. These flammables are extremely dangerous and may cause an
explosion, a fire, or
injury. As originally manufactured, this unit contains refrigerant installed by
Hisense/HITACHI. Hisense/
HITACHI uses only refrigerants that have been approved for use in the unit’s intended
country or market.
Hisense/HITACHI’s
distributors similarly are only authorized to provide refrigerants
that
have been
approved for use
in the countries or markets they serve. The refrigerant used in this unit
is
identified on
the unit’s faceplate
and/or in the associated manuals. Any additions of refrigerant into this
unit must
comply with the country’s
requirements with regard to refrigerant use and should be obtained
from
Hisense/
HITACHI distributors. Use of
unapproved refrigerant substitutes will void the warranties
and can
cause injury or death.
● Do
not
pour
water
into
the
indoor
or
outdoor
unit.
These
units
are
equipped
with
electrical
parts.
Exposure
to
water
may
cause
a
serious
electrical
shock.
● Do
not
open
the
service
cover
or
access
panel
for
the
indoor
or
outdoor
units
without
turning
OFF
the
main
power
supply.
● Do
not
touch
or
adjust
safety
devices
inside
the
indoor
unit
or
outdoor
units.
If
these
devices
are
touched
or
readjusted,
it
may
cause
a
serious
accident.
● Carefully
check
for
escaping
refrigerant
gas.
If
there
is
significan
t
leakage,
it
can
cause
difficult
y
in
breathing.
Turn
OFF
the
main
switch,
and
contact
your
service
contractor
if
refrigerant
leakage
occurs.
● Make
sure
that
the
refrigerant
leakage
test
is
performed.
Refrigerant
(fluorocarbon
for
this
unit
is
incombustible,
non-toxic
and
odorless.
However
if
the
refrigerant
is
leaked
and
comes
in
contact
with
fire
toxic
gas
will
generate.
Because
fluorocarbo
n
is
heavier
than
air,
the
floo
surface
will
be
fille
d
with
it,
which
could
cause
suffocation.
● The
installer
and
system
specialist
shall
secure
against
refrigerant
leakage
according
to
local
regulations
or
standards.
● Use
a
Earth
Leakage
Breaker
(ELB).
In
the
event
of
fault,
there
is
danger
of
an
electric
shock
or
a
fir
e
if
it
is
not
used.
