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

speed
for
10

minutes
in
order

to
return
com

pressor

oil
to

compressor

2

Stop
the

engine
and

discharge

and
then

remove

from
the

due

to

remove

and

repair
as

necessary
Then

pour

CAUTION

a
The
oil
should
not
be
transfused

from
a
container
into
another
as

the
failure
will

possibly
cause

moisture
to
mix
with

b
The

c
The
