Notabilia as a unit designed for R410A
•
Do
not
use
any
refrigerant
other
than
R410A.
R410A
will
rise
to
pressure
about
1.6
times
higher
than
that
of
a
conventional
refrigerant.
A
cylinder
containing
R410A
has
a
pink
indication
mark
on
the
top.
•
A
unit
designed
for
R410A
has
adopted
a
different
size
indoor
unit
service
valve
charge
port
and
a
different
size
check
joi
nt
provided
in
the
unit
to
prevent
the
charging
of
a
wrong
refrigerant
by
mistake.
The
processed
dimension
of
the
flared
part
of
a
refrigerant
pipe
and
a
flare
nut’s
parallel
side
measurement
have
also
been
al
tered
to
raise
strength
against
pressure.
Accordingly,
you
are
required
to
arrange
dedicated
R410A
tools
listed
in
the
table
on
the
left
before
installing
or
servicing
this
unit.
•
Do
not
use
a
charge
cylinder.
The
use
of
a
charge
cylinder
will
cause
the
refrigerant
composition
to
change,
which
results
in
performance
degradation.
•
In
charging
refrigerant,
always
take
it
out
from
a
cylinder
in
the
liquid
phase.
•
All
indoor
units
must
be
models
designed
exclusively
for
R410A.
Check
connectable
indoor
unit
models
in
a
catalog,
etc.
(A
wr
ong
indoor
unit,
if
connected
into
the
system,
will
impair
proper
system
operation)
