HALIDE
LEAK
DETECTOR

Since
the

propane
leak
detector
and

butane
leak
detector
are
the
same
in

respect
to
their

operation
this
section

describes
the

operation
of
the

propane

leak
detector

The

copper
screen
is
heated

by
the
Air

Conditioning

burning
of

propane
Refrigerant
gas

decomposes
to
color
the

flame
when
it

contacts
the
heated

screen
The

gas
to

be
checked
is
drawn
into
the

sampling

tube
and

sent
out
to
the
burner
A

refrigerant
leak
can
clearly
be

detected

by
variations
in
the
color
of
the

flame

The

when
there
is
no

refrigerant

being

burned
When
there
is

a

the

will
be

When

Place
the
end
of

sampling
tube

near
the

point
of
the

suspected
leak
in

system

Note

a
Since

refrigerant
gas
is

heavier
than

air
small
leaks

can
be

easily
detect

ed

by

placing
sampling
tube
direct

ly
below
the
check

point
b
Suitable
ventilation
is

required
If

refrigerant
gas
is

mixed
with
the

surrounding
air
leak
detector
will

always
indicate
a

response
and

detection
of
the
actual
leak
will
be

difficult

c
Never

hold
leak
detector
at
an

angle

WARNING

a
Never
inhale
the
fumes

produced

by
combustion

of

refrigerant
gas

since

they
are
toxic

b
Never
use

in
a

place

where

Sight

One

guide
for
whether

there
is

enough
refrigerant
in

syst
m
is

given
by
observing
refrigerant
flow

through
sight
glass
However
this

method
is
unsuitable
for

judging
the

aJTlount
of

refrigerant
The
correct

refrigeranl
level
can
be

judged
by

measuring
the
