The
outdoor
units
are
shipped
with
a
refrigerant
charge
to
match
the
indoor
unit
and
25
ft.
(7.5m)
of
refrigerant

If
shorter
or
longer
lines
are
used,
the
charge
will
have
to
be
adjusted.

Restrictor
Orifice
Some
indoor
matches
use
a
restrictor
orifice
in
the
fitting
at
the
indoor
coil.
Some
matches
may
require
a
different
ori-
fice
for
proper
system
performance
and
it
must
be
changed
before
the
refrigerant
lines
are
connected.
Changing
the
Restrictor
Orifice
The
restrictor
orifice
is
located
in
a
fitting
in
the
liquid
line.
The
fitting
is
actually
the
distributor
end
of
the
cap
tube
as-
sembly.
1.
Remove
the
liquid
line
fitting
and replace
restrictor
ori-
fice.
(STANDARD
RIGHT
HAND
THREAD)
2.
Make
sure
the
restrictor
is
installed
with
the
rounded
end
toward
the
feeder
tubes.

Ifitis
necessary
to
add
tubing
in
the
field,
use
dehydrated
or
dry
sealed
deoxidized
copper
refrigeration
tube.
DO
NOT
use
copper
water
pipe.
Itis
important
that
no
tubing
is
cut
or
seals
broken
until
you
are
ready
to
actually
make
connections
to
the
evaporator
and
to
the
condenser
section.
Do
not
remove
rubber
plugs
or
copper
caps
from
the
tube
ends
until
ready
to
make
connections
at
evapora-
tor
and
condenser.
PLEASE!
UNDER
NO
CIRCUMSTANCES
LEAVE
THE
LINES
OPEN
TO
THE
ATMOSPHERE
FOR
ANY
PERIOD
OF
TIME.
Be
extra careful
with
sharp
bends.
This
tubing
can
kink”
very
easily,
and
if
this
occurs,
the
entire
tube length
will
have
to
be
replaced.
Extra
care
at
this
time
will
eliminate
future
service
problems.
Suspension
And
Installation
Of
Refrigeration
Lines
DO
NOT
fasten
liquid
or
suction
lines
in
direct
contact
with
the floor
or
ceiling
joist.
Use
an
insulated
or
suspension
type
of
hanger.
Keep
both
lines
separate,
and
insulate
the
suction
line.
Both
lines
should
be
insulated
in
extremely
long
runs
in
an
attic
or
underground
in
a
raceway,
50’
or
more.
