Installation
Instructions
Split
System
Condensers
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
fom
(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.

Line
Valves
The
outdoor
condensing
unit
is
supplied
with
straight
sweat
brass
service
valves
with
copper
stubs.
All
line
valves
are
positioned
to
seal
the
refrigerant
in
the
condensing
unit
with
gauge
ports
open
to
connecting
lines
when
the
Schraeder
valve
is
depressed.
Gauge
ports
have
Schraeder
installed
and
require
use
of
charging
hoses
with
depressors.
Brazing
Connections
Fire
Hazard
Refrigerant
and
oil
mixture
under
pressure
could
ignite
as
it
escapes
and
contacts
brazing
torch
resulting
in
Fire.
Make
sure
the
refrigerant
charge
is
properly
removed
from
both
the
high
and
low
sides
of
the
system
before
brazing
any
compo-
nent
or
lines.
FAILURE
TO
DO SO
COULD
RESULT
IN
BODILY
INJURY
OR
DEATH.
Before
making
braze
connections,
be
sure
all
joints
are
clean.
Before
heat
is
applied
for
brazing,
nitrogen
should
be
flowing
through
the
tubing
to
prevent
oxidation
and
scale
formation
on
the
inside
of
the
tubing.
Liquid
&
Suction
Lines
Fully
annealed
refrigeration
lines
should
be
used
when
installing
the
system.
The
following
is
the
recommended
method
for
making
braze
connections
at
the
refrigerant
line
connections:
1.
Clean
refrigerant tube
end
with
emery
cloth
or
steel
brush.
2.
Use
a
suitable
brazing
alloy
for
copper
to
copper
joints.
3.
Insert
tubing
into
swage
fitting
connection.
4.
Apply
heat
absorbing
paste
or
heat
sink
product
to
pre-
vent
damage
to
the
service
valve.
CAUTION
Do
not
heat
valve
body
above
250
degrees
F.
5.
Braze
joint.
6.
Quench
the
joint
and
tubing
with
water
using
a
wet
rag.
Leave
rag
on
fitting
body
and
re-wet
with
water
to
help
cool
area.
Evacuating,
And
Charging
Instructions
NOTE
Intentional
release
of
CFC
or
HCFC
Refrigerant
to
the
Atmosphere
violates
Federal
Law.
It
may
also
violate
State
and
Local
Codes.
Check
all
Federal,
State
and
Local
Codes
before
proceeding.
These
instructions
are
intended
for
use
with
condensing
units
that
are
precharged
at
the
factory
with
adequate
re-
frigerant
to
handle
25
feet.
NOTE:
Do
not
use
any
portion
of
the
charge
for
purging
or
leak
testing.
It
is
mandatory
that
a
thorough
evacuation
of
the
refrigerant
in
the
piping
and
evaporator
be
performed.
The
liquid
line
and
suction
line
service
valves
have
been
closed
after
final
testing
at
the
factory.
Do
not
disturb
these
vaives
until
the lines
have
been
leak
checked
and
evacuated
or
the
charge
in
the
unit
may
be
lost.
