medium,
at
the
time
of
infusion,
you
must
turn
on
cylinder
valve
a
little
to
avoid
wasting
freezing
medium
and
affecting
maintenance
progress.
When
infusing
low
temperature
level
freezing
medium,
machine
shall
also
be
under
the
status
of
stop,
firstly,
infuse
HRA
freezing
medium,
then
infuse
HRB
freezing
medium;
as
HRB
freezing
medium
has
very
high
pressure,
ordinary
cylinders
cannot
bear
very
high
pressure,
so
oxygen
cylinders
are
used
to
contain
HRB
freezing
medium;
at
the
time
of
using,
the
exit
at
the
bottom
of
cylinder
must
be
plugged
up
with
a
screw
to
prevent
freezing
medium
from
leaking.
The
top
opening
can
be
used
for
infusion;
when
infusing
above
freezing
mediums,
cylinders
can
be
infused
with
gas
vertically.
To
ensure
the
accuracy
of
freezing
medium
infusion,
at
the
time
of
infusing
all
freezing
mediums,
an
electronic
scale
shall
be
used
to
weigh
the
infusion.
If
the
evacuation
time
of
machine
system
freezing
medium
infusion
are
not
carried
out
according
to
above
time
requirement
and
operation
flow,
as
a
result,
a
machine
has
bad
refrigeration
or
no
refrigeration,
and
the
machine
is
replaced
or
returned,
once
verified
by
our
head
office,
those
that
are
re
‐
maintained
shall
be
claimed
according
to
two
times
of
the
machine’s
maintenance
cost,
in
case
that
machine
is
replaced
or
returned,
the
maintenance
shop
shall
pay
for
the
cost.
As
the
system
of
DW
‐
86L388
series
of
ultra
‐
low
temperature
cabinet
products
has
very
strict
requirement
for
the
infusion
quantity
accuracy
(gram)
of
freezing
medium,
maintenance
shops
must
prepare
a
standard
electronic
scale
within
the
error
of
3
grams
before
maintenance,
as
the
freezing
medium
of
ultra
‐
low
temperature
machine
is
made
up
of
concentrated
freezing
medium
mixtures,
the
infusion
quantity
marked
on
the
back
of
machine
is
only
used
for
reference,
it
is
not
actual
infusion
quantity,
before
infusing
freezing
medium,
maintenance
personnel
must
contact
the
Head
Office,
which
will
provide
maintenance
guidance.
