CHECK

The
oil
used
to

while

compressor
is

operating

Therefore
to

correctly
measure
com

the
amount
of
oil

flowing

to

system
must
be
considered
If
a

considerable
amount
of

happens
the

leakage
of

compressor
oil
is
also

considered

There

When

checking
the

or
when

replacing
any

component

of
the

system
use
the

following
service

procedure
This

facio

litates
to

due

to

faulty

or

heavy
loss
of

refrigerant
remove

compressor
and

repair
as

necessary
Then

pour

up

to

correct
level
and

After
above

steps
have
been

com

CAUTION

a
The
oil
should
not
be
transfused

from
a
container
into
another
as

the
failure
will

possibly
cause

moisture
to
mix
with
the

b
The
used
oil
should
not

c
The

are

noticeable
leaky

should
be

repaired
Then

not

operate

level

excessively
low

If
this
caution
is

neglected
a

will
result
since
