DESCRIPTION
The Type H-10 Leak Detector consists of a
control unit, probe, 6-foot hose, and a 6-foot
power cord house d in a shock resistant vinyl case:
gray case for 110- volt unit and brown case for
240-volt unit.
The control u nit contains a printed - circuit
board amplifier, plug-in sensitive element, air-
pump, and power tr ansformer housed be neath a chas-
is cover. --. A refe r ence leak, sens it iv it y switch
and a balance co nt rol are located on the top of
the control chas s is. (See Fig . 1.)
The probe, consisting of a nozzle with a
transparent tip, air-flow ball, and neon leak-
signal lamp is connected to the control chassis by
a length of flexible tubing.

Leak
Detector
Components.
The
reference
leak
assembly
is
a
built-in
bottle
containing
a
refrigerant
gas
(R-11)
and
is
calibrated
to
provide
a
leak
equivalent
to
ap-
proximately
1/2
ounce
of
refrigerant
(R-12)
gas
per
year.
The
accessories
provided
with
the
leak
de-
tector
consist
of
a
maintenance
kit
(filters
and
airflow
balls).
APPLICATION
The Type H-10
leak
detector
was
designed
pri-
marily
for
use
as
a
serviceman's
tool.
Although
it
can
be
used
for
production-line
leak
checking,
it
was
not
designed
for
this
type
of
service.
Normally
the
serviceman
will
use
it
for
leak
checking
automobile
air
conditioning,
home
and/or
for
coumercial
air
conditioning
or
refrigeration
equipment.

~ • PHERE SINCE THE AMBIENT ATMOS-
PHERE IS DRAWN THROUGH THE PROBE AND OVER THE EL-
EMENT WHICH · OPERATES AT APPROXIMATELY 1800F. THE
RESULTING COMBINATION OF AIR AND GAS MIXTIJRES ·
COULD CAUSE AN EXPLOSION.
Contamination of the testing area may cau . se
erratic operation of the leak detector. This can
occur when the leak in the system is very large
and there is little or no ventilation in the test-
ing area. Contamination of an area may also occur
where excessive amounts of refrigerant gases are
used. The leak detector cannot differentiate be-
tween atmospheric contamination and an actual leak,
because it will respond to any halogen gas passing
over the sensitive element.
A contaminated condition can be greatly re-
duced by ventilating the area or isolating the
leak-check area.
IMPORTANT: -- TO PROLONG THE LIFE OF THE SENSITIVE
ELEMENT, NEVER PLACE THE PROBE IN A STREAM OF RE-
FRIGERANT AS THIS WILL DRASTICALLY SHORTEN ELEMENT
LIFE. ,
NarE: Variations in the line voltage may
cause the same leak detector reactions as mentioned
for atmospheric contamination. If this is a prob-
lem, a voltage stabilizing device I!Llst be used.
OPERATION
The condensed operating instructions appear
on the front page.
WAINING
I
DO Nar OPERATE IN AN EXPLOSIVE
OR COMBUSTIBLE ATMOSPHERE •
._ ___ _
To operate the Type H-10 leak detector, pro-
ceed as follows:
1. Before using the Type H-10 leak detector
for the first time, remove the screw from the cap
on the REFERENCE LEAK assembly (2, Fig. 1) and al-
low 15 minutes for the leak rate to stabilize. This
screw is used for shipping only and should not be
replaced. Be certain that the leak-reference bot-
tle contains a quantity of refrigerant (R-11). The
liquid level can be observed through the window
(1, Fig. 1) provided in the chassis. (This bottle
4

is
filled
with
enough
refrigerant
to
last
approxi-
mately
i
year.)
2.
Plug
the
power
cord
(3,
Fig.
1)
into
a
120-
volt,
60-cycle
outlet
(gray
case
only);
or
plug
the
power
cord
into
a
240-volt,
50/60-cycle
outlet
(brown
case
only).
IMPORTANT:
--
DO
NOT
ATTEMPT
TO
OPERATE
THE
DETECTOR
AT
VOLTAGES
ABOVE
OR
BEU:ll
THE
VALUES
GIVEN
ON
THE
RATING
PLATE.
THE
LEAK
DETECTOR
COULD
BE
DAMAGED.
3.
The
leak
detector
will
start
to
warm
up
iumediately
after
the
power
cord
is
plugged
into
an
outlet.
4.
Check
for
sufficient
air-flow
by
pointing
the
probe
tip
toward
the
floor
and
observing
the
air
flow
ball
(in
the
probe).
If
the
air-flow
is
cor-
rect,
the
ball
will
rise
and
float
above
the
tip
of
the
probe.
(See
Fig.
2.)
The
height
the
ball
rises
is
not
important
as
long
as
it
rises.
If
the
air-flow
ball
does
not
rise,
tap
the
probe
lightly
to
make
sure
the
ball
isn't
sticking.
If
the
ball
does
not
rise
at
all
due
to
insufficient
air-flow,
the
unit
should
be
forwarded
to
the
nearest
Gener-
al
Electric
apparatus
shop.
5.
Place
the
SENSITIVITY
switch
(9,
F:l
g.
1)
in
either
the
HIGH
or
L~
positions.
The
L~
range
position
is
used
to
detect
large
leaks
and
is
used
when
the
elements
are
new. The
HIGH
range
position
is
used
to
detect
small
leaks.
After
the
leak
detector
has
been
in
use
for
some
time,
the
response
of
the
element
will
decrease
and
it
will
be
necessary
to
place
the
SENSITIVITY
switch
in
the
HIGH
range
position
for
all
leak
checking.
This
can
be
determined
by
placing
the
SENSITIV!TY
switch
on
the
L~
range
'
position
and
turning
the
BALANCE
control
(4,
Fig.
1)
until
the
lamp
(1,
Fig.
2)
just
ceases
to
flash;
then
hold
the
probe
to
the
REFERENCE
LEAK.
Observe
whether
the
light
can
be
made
to
flash.
If
no
flash
occurs
,
or
if
the
flashing
rate
decreases
when
the
probe
i s
continually
held
at
the
REFERENCE
LEAK,
the
SEN
SIT
I-
VITY
switch
nrust
be
placed
at
the
HIGH
range
po
si
-
tion
and
the
unit
rebalanced.
NOTE:
In
a
highly
contaminated
area,
t
he
flas
h
rate
will
not
be
stable
and
it
will
be
almost im-
possible
to
''balance"
the
detector.
Under t
hese
conditions,
leak
checking
would
not
be
pos
sible.

so
that

and
continue
to

when

When
the

is
removed from

the

will
slow

stop.
NarE:
On
some
of
the
Type
H-10
leak
detectors,
the
flashing
light
may
not
shut
off
when
the
sensit-
ivity
switch
is
on
the
HIGH

position.
This
is
not
a
defect,
but
indicates
a
very
sensitive

in
which
case
the
leak
detectBr
should
be
operated
in
the
LCW
range
position
until
the
el~ment
wears
in,

The
REFERENCE
LEAK
may
be
used
as
often
as
necessary
to
assure
proper
operation
of
the
leak
de-
tector,
or
as
a
comparing
means
to
assist
in
deter-
mining
the
size
of
the
leak,
The
response
when
probing
the
REFERENCE
LEAK
is
approximately
the
same
as
a
leak
of
one-half
ounce
of
refrigerant
(R-12)
per
year.
A
leak
which
causes
a
flashing
rate
equal
to
that
produceq
by
the
REFERENCE
LEAK
would
indicate
a
leak
rate
of
approximately
the
same
size,
8,
Hold
the
probe
as
closely
as
possible
to
the
area
being
tested
and move
the
tip
at
one
inch
per
second
along
seams
or
joints
suspected
of
leak-
ing,
When
the
probe
encounters
a
leak,
the
flash-
ing
rate
of
the
neon
lamp
will
increase
and
will
continue
to
flash
at
the
faster
rate
as
long
as
the
'
probe
is
held
at
the
leak,

MAINTENANCE
The Type
H-10
leak
detector
is
designed
for
long
life
with
little
or
no
maintenance.
A
main-
tenance
kit
which
contains
the
necessary
replace-
ment
parts
is
supplied
with
each
leak
detector.
Instructions
for
replacing
these
expendable
items
are
described
on
the
following
sections.
Filter
Replacement
To
protect
the
.
air
pump
from
damage
from
for-
eign
particles
and
moisture,
replace
the
filter
(3,
Fig.
2)
often.
Once a month
with
moderate
use
(15-30)
minutes
-
per
day)
is
not
too
often.
To
replace
the
filter,
pick
out
the
old
filter
with
a
pin
or
tweezers.
The
fine
screen
will
re-
main
in
the
tip.
Insert
the
new
filter
in
the
tip
and make
sure
it
is
firmly
seated
against
the
fine
screen.
Sensitive
Element
Assembly
Replacement
The
sensitive-element
is
a
plug-in
unit
that
is
to
be
thrown
s:.1ay
when
expended.
The
element
will
need
replacement
when
the
leak
detector
will
no
longer
respond
to
the
REFERENCE
LEAK
with
the
SENSITIVITY
switch
in
the
HIGH
position.
(Make
sure
the
reference-leak
assembly
contains
R-11
re
t
riger-
ant.)
·
To
replace
the
plug-in
element
assembly
pro-
ceed
as
follows:
1.
Unplug
the
power
cord
and
remove
the
screw
(5,
Fig.
1)
holding
the
chassis
to
the
vinyl
case
and
remove
chassis.
The
element
assembly
is
at
the
opposite
end
of
the
chassis
from
the
REFERENCE
LEAK.
2.
Make
sure
the
element
assembly
is
cool
be-
fore
attempting
its
removal.
3.
Insert
a new
element
assembly.
4.
Replace
chassis
in
vinyl
case
and
secure
in
place
with
screw
removed
in
step
1•
.
Reference
Leak
The
refrigerant
gas
(R-11)
contained
in
the
reference
leak
will
last
for
approximately
1
year
under
normal
operating
conditions.
To
refill
the
assembly,
proceed
as
follows:
1.
Remove
the
chassis
from
the
vinyl
case
as
described
in
previous
section.
2.
Hold
the
bottle
firmly
in
place
and remove
cap.
(Note:
Make
sure
discs
remain
in
position
in
·
the
cap.)

3.
Remove
the
bottle
and
fill
with
refriger-
ant
(R-11)
(approximately
7/8ths
full).
NarE:
Refilling
the
reference
leak
bottle
with
(R-11)
refrigerant
will
be
easier
if
done
at
temperatures
below
75F.
4.
Replace
the
bottle
in
chassis.
The
rubber
0-ring
on
the
bottle
holds
the
bottle
assembly
in
place
on
the
mounting
plate.
The
0-ring
~hould
be
pulled
back
on
the
bottle
while
the
cap
is
tight-
ened.
Tighten
cap,
·making
sure
discs
remain
in
position
in
the
cap.
After
the
cap
has
been
tight-
ened,
push
the
0-ring
up
to
the
mounting
plate
and
seat
in
the
neck
of
the
bottle.
