SEALED
SYSTEM
SWEEP
CHARGE
SERVICING
PROCEDURES
Sealed
system
sweep
charge
processing
is a modified
procedure
different
from the evacu-
ation
method
employing a
vacuum
pump
and
micron
gauge
that
were
used
in the
past.
Through extensive
evaluation,
we
have
concluded
if
the
sweep charge
procedure
is
prop-
erly
done
there should be
no long
term
adverse
affects on
product performance.
It
significantly
reduces the
amount
of equipment and
time required
to
properly
complete
a
sealed
system
repair.
As
in the
past,
technicians using this sweep
charge
process
must be
thoroughly
familiar
with
brazing
techniques, sealed system
diagnosis and
repair methods.
