INSTALLATION

It
is

important
that

the

body

be

checked

thoroughly

before
installation
of
the

replacement

The

procedure
below

outlines
the
method
which

may
be

BF

used
to
check

the

opening

I

Check
windshield

weatherstrip

for

irregularities

2

Clean
off
old
sealer

opening
and

check
entire

body

irregularities

3
With
the
aid
of

CAUTION

Care
should
be
exercised
not
to
let

glass
strike

body
metal

during
installa

tion

Edge
chips
can
lead
to
future

breaks

glass
supported

and
centered
in

body
opening
check

relationship
of

glass
to

I
The
inside

surface
of

glass

should

completely
lap
to

body
flange

2
The
curvature
of

glass
should
be

uniform
to
that

of
the

body
opening

5

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

or
below

with

controls
set
for

maximum

cooling

and

high

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

amount
of

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
