Recommended
Method
Of
Evacuating
A
System
1.
Connect
the
vacuum
pump
to
the
suction
and
liquid
line
gauge
ports.
2.
If
the
evacuation
is
being
performed
on
a
new
system
installation,
the
valves
should
be
kept
in
the
"front
seated”
(closed)
position.
This
will
allow
the
mechanic
to
evacuate
the
refrigeration
lines
and
the
indoor
coil,
without
disturbing
the
factory
charge
in
the
outdoor
unit.
3.
Follow
the
vacuum
pump
manufacturer’s
instructions.
Allow
the
pump
to
operate
until
the
system
has
been
eva-
cuated
down
to
300
microns.
Allow
the
pump
to
continue
running
for
an
additional
15
minutes.
Turn
off
the
pump
and
leave
the
connections
secured
to
the
two
service
valves.
After
5
minutes,
if
the
system
fails
to
hold
500
microns
or
less,
check
all
connections
for
tight
fit
and
repeat
the
evac-
uation
procedure.
4.
Isolate
the
vacuum
pump
from
the
system
by
closing
the
shutoff
valves
on
the
gauge
bar.
Disconnect
the
vacuum
pump.
Valve
Actuation:
Service
Valves
Remove
the
service
valve
cap,
if
there
is
a
male
valve
stem
see
instructions
for
Ball
Valves.
For
the
standard
service
valve
there
are
two
variations,
but
both
have
internal
stems.
The
first
style
uses
an
internal
snap
ring
to
retain
the
valve
stem
and
the
second
has
a
rolled
top
and
also
has
finer
threads
on
the
valve
cap.
NOTE:
You
may
encounter
more
than
one
type
of
valve
on
a
unit.
For
service
valves
fully
insert
a
hex
wrench
into
the
stem.
A
back-up
wrench
is
required
on
the
valve
body
to
open
the
valve
stem.
Backout
counterclockwise
until
the
valve
stem
stops
or
just
touches
the
retaining
ring.
NOTE:
THIS
IS
NOT
A
BACKSEATING
VALVE.
For
valves
with
retainer
rings
care
must
be
taken
to
prevent
dislodging
them
when
opening
valve.
Electrical
Wiring
The
service
valve
cap
is
a
primary
seal
for
the
valve
and
must
be
properly
tightened
to
prevent
leaks.
Make
sure
cap
is
clean
and
apply
refrigerant
oil
to
threads
and
sealing
sur-
face
of
cap.
For
valves
with
retaining
rings:
Replace
service
valve
cap
and
torque

If
torque
wrench
is
not
available,
tighten
cap
finger
tight
and
then
tighten
one
(1)
additional
wrench
flat
or
1/6
of
a
turn.
For
valves
with
rolled
tops:
Replace
service
valve
cap
tighten
cap
finger
tight
and
then
tighten
one
(1)
additional
wrench
flat
or
1/6
of
a
turn
to
properly
seat
the
sealing
sur-
faces.
Subsequent
installations
will
seat
with
1/2
to
1
wrench
flat
of
turning.
Gauge
Ports:
All
Valves
Check
for
leaks
at
the
schrader
port
and
tighten
valve
core
if
necessary.
Install
plastic
caps
finger
tight.
Ball
Valves
On
models
with
ball
type
valves
use
a
6”
crescent
wrench
to
rotate
the
valve
stem
90°
counter
clockwise.
Retighten
valve
cap
to
6-8
ft.
lbs.
If
torque
wrench
is
not
available,
tighten

and
then
tighten
one
(1/2)
additional
wrench
flat.
