No
other

refrig

than
the

This

refrigerant
is

usually
available

in

a

cylinder
In

either

case
it

is

liquefied

Use

IN

INSPECTION

Both

periodic
maintenance
and

season
in

inspection
are

most
essential

to
enable
the
air

conditioner
to

give

full

performance

Perform
the

following
checks

Start

and

check

refrigerant

through

For

details

Check
the
entire

for

of

refrigerant
leaks

Refer
to
relative

topics
under

Checking
for

Leaks

and

Refrigerant
Leaks

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

to

locate

leaking
points

ENERAL

The

servicing
of
the
air

should
be
carried
out

only
by
well

trained
servicemen
This

essential

points

Jf

a

amount
of

dirt
and
sand

enter

the

system
they
will
be

carried
with

refrigerant
and

may

clog
the

system
or
scratch

rotating

parts
This

points
out
the
need
for

care
in

servicing
the

system
That

is

disconnecting

joints
should
be

carried
out

in
a
dean

place

Water
should
not
be
allowed
to

get

inside
the

system
The

refrigerant

does
not

readily
mix

with
water

However
the

presence
of
even
a

minute

amount
of

water
will
cause

a
chemical
reaction

at

high
tem

perature
which
will
in

turn

produce

hydrochloric
acid

HCl
Since

hydrochloric
acid
is

highly
corro

sive
to
metals
the
aluminum
and

copper
piping
etc
will
become

corroded
and
the

refrigeration

system
will
become

clogged
