COMPRESSOR

OIL
LEVEL
CHECK

The
oil
used
to
lubricate

compres

sor
circulates
into

system
from
the
oil

sump
while

compressor
is

operating

Therefore
to

correctly
measure
com

pressor
oil
the
amount
of
oil

flowing

to

system
must
be
considered
If
a

considerable
amount
of

leakage
of

refrigerant
gas
happens
the

leakage
of

compressor
oil
is
also

considered

There
will
be
no

compressor
oil
leak

age
from
a

completely
sealed

system

When

system
operates
under

satisfying

condition
the

compressor
oil
level

check
is

unnecessary

When

checking
the
level
of
com

pressor
oil

or
when

replacing
any

component
part
of
the

system
use
the

following
service

procedure
This

facio

litates
to

return
oil
to

compressor

1

Operate
compressor
at

or
below

with

controls
set
for

maximum

cooling

and

high
blower

speed
for
10
to
15

minutes
in
order

to
return
com

pressor

oil
to

compressor

2

Stop
the

engine
and

discharge

refrigerant
of

system
and
then

remove

compressor
from
the

car

3

Remove

6
Discard
the
used
oil
and
fill
with

the
same

amount
of

new
oil
Add

oil
if

found
less

than
above
amount

If

compressor
is

inoperative
due

to

faulty
compressor
or

heavy
loss
of

refrigerant
remove

compressor
and

repair
as

necessary
Then

pour
oil

up

to

correct
level
and
install
on

engine

After
above

steps
have
been

com

pleted
recheck

level
drain
oil

to

correct

if
level
is

excessively
high

CAUTION

a
The
oil
should
not
be
transfused

from
a
container
into
another
as

the
failure
will

possibly
cause

moisture
to
mix
with
the
oil

b
The
used
oil
should
not
be
returned

into

a
container

c
The
oil
should
not
be
used
if
its

state
of

preservation
is
not
clear

enough

PERFORMANCE
TEST

The

cooling

ormance
of
the

air

conditioner

changes
considerably
with

changes
in

surrounding
conditions

Testing
must
be

performed
using
the

correct
method
This
test
is
used
to

judge
whether

system
is

operating
cor

rectly
and

can
also
be
used

as
a

guiqe

in

checking
for

problems

1
Park

REFRIGERANT

LEAKS

If
leaks
are

noticeable
leaky
parts

should
be

repaired
Then
system

should

be

CAUTION

00

not

operate
compressor
with

refrigerant
level

excessively
low

If
this
caution
is

neglected
a
burnt

compressor
will
result
since

usually
indicates
