The outdoor
units
are
shipped
with
a
refrigerant
charge
to
match
the
indoor
unit
and
15
ft.
(4.5m)
of
refrigerant
line.
If
shorter
or
longer
lines
are
used,
the
charge
will
have
to
be
adjusted.
OUR
STANDARD
RECOMMENDED
REFRIGERANT
LINE

IS
75
ft.
WITH
A
MAXIMUM
VERTICAL
SEPARATION
OF
50

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.

Sets
If
itis
necessary
to
add
tubing
inthe
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
long
runs
in
an
attic
or
underground
in
a
raceway.
Do
not
let
refrigerant
lines
come
in
direct
contact
with
foundation.
When
running
refrigerant
lines
through
the
foundation
or
wall,
the
openings
should
be
made
large
enough
to
allow
for
a
sound
absorbing
material
to
be
placed
or
installed
between
the
tubing
and
the
foundation.
This
will
prevent
noise
transmission
between
the
tubing
and
the
wall
section
(foundation)
or
the
building.
Installation
Instructions
For
Condensing
Units
That
Are
Higher
Than
Evaporator
It
is
recommended
that
vertical
suction
risers
not
be
up-
sized.
Proper
oil
return
to
the
compressor
should
be
main-
tained
with
suction gas
velocity.
If
velocities
drop
below
1500
fpm
(feet
per
minute),
oil
return
will
be
decreased.
An
oil
trap
should
be
installed
every
20’
of
vertical
suction
line
riser
(condenser
above
evaporator.)
Refer
to
line
sizing
charts.
