REFRIGERANT

LEAKS

If
leaks
are

noticeable

leaky
parts

should

be

repaired
Then

system

should
be

filled
with

refrigerant
Do

not

operate
compressor
with

refriger

ant

level
e

cessively
low

If
this
caution
is

neglected
a
burnt

compressor
will

result
since

heavy
loss

of

refrigerant
usually
indicates

heavy

loss
of

compressor
oil

If

system
has

been

exposed
to

atmosphere
for
an

extended

period
of
Air

Condition

ing

time

receiver

dryer
must

be

replaced

If
leaks
are

slight
and
no
air
is

present

in

system
add

refrigerant
as

necessary

To

detect
leaks
refer
to

relative

topics
under

Checking
for

Leaks

Here
is

how
leaks
are

stopped

I

Check

torque
on
the

connection

fitting
and

if
too
loose

tighten
to

the

proper

torque
Check
for

gas

leakage

with

a
leak

detector

2
If

leakage
continues

even
after

AC
18
the

fitting
has
been

retightened
dis

charge

refrigerant
from

system
discon

nect
the

fittings
and
check
its

seating

face
for

damage
Always

replace
even

if

damage
is

slight

3
Check

compressor
oil

and
add
oil

if

required

4

Charge

refrigerant
and
recheck

for
