Notes
a
The
bubbles
seen
through
the
sight
glass
are
influenced
by
the
ambient
temperature
Since
the
bubbles
are
hard
to
show
up
in
comparatively
low
temperatures
below
200C
6S0
F
it
is
possible
that
a
slightly
larger
amount
of
refrigerant
would
be
filled
if
supplied
according
to
the
sight
glass
Be
sure
to
recheck
the
amount
when
it
exceeds
200C
680F
In
higher
temperature
the
bubbles
are
easy
to
show
up
b
When
the
screen
in
the
receiver
dryer
is
clogged
the
bubbles
will
appear
even
if
the
amount
of
refrig
erant
is
normal
In
this
case
the
outlet
side
pipe
of
the
receiver
dryer
becomes
considerably
cold
PERFORMANCE
TEST
Check
for
the
amount
of
refrigerant
in
the
system
can
be
made
by
meas
uring
pressure
on
discharge
side
The
correct
amount
of
refrigerant
is
in
the
system
if
pressure
on
the
discharge
side
is
within
the
specified
range
For
details
refer
to
Perform
ance
Test
described
later
Overcharging
will
show
up
in
higher
pressure
on
discharge
side
COMPRESSOR
OIL
LEVEL
CHECK
The
oil
used
to
lubricate
compres
sor
circulates
into
system
from
the
oil
sump
while
c9mpressor
is
operating
The
efore
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
fa
cilitates
to
return
oil
to
compressor

then
remove

3
Remove

Then
pour

have
been

PERFORMANCE
TEST
The
cooling
performance
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
guide
in
checking
for
problems
