DESCRIPTION

The

bumpers
consist

essentially
of

a

bumper
two

side

and
two
shock
absorbers

The

bumper
is

attached
to
the
side

through
a

gas
filled
strut

type
shock
absorber
at
each
end
to

effectively
absorb
the

energy
of
a

collision

is
constructed

with

a

CHECKING
FOR

LEAKS

Conduct
a
leak
t
st
whenever
leak

age
of

refrigerant
is

suspected
and

when

conducting
service

operations

which
are

accompanied
by

disassembly

or

loosening
of
connection

fittings

Refrigerant
is

a
colorless
odorless

gas
and

leakage
from

system
is

diffi

cult
to
detect

Accordingly
the
use
of

a
leak
detector
facilitates
check
for

leaks
Two

methods
of

checking
are

available
one

employs
a

halide
leak

detector
which
bums

propane

gas
or

butane

gas
and
the
other
is

an
electric

type
leak

detector

If

any
trace
of
oil
is

noted
at
and

around
connection

fittings
it
is

a
sure

indication
that

refrigerant
is

leaking

This
condition
can
be
corrected

easily

by

retightening
the

joints
If

any

joint

on
line
is

suspected
of
small
amount
of

leakage
use
a
leak
detector
to
locate

leaking
points

HALIDE
LEAK
DETECTOR

Since
the

propane
leak
detector
and

butane
leak
detector
are
the
same
in

respect
to
their

operation
this

describes
the

The

be
checked
is
drawn
into
the

sent
out
