A. Unit Storage:
1:Unscrew the drainage cover, unplug the water plug, and discharge the water in the water
pan into other water containers or directly tilt the body to discharge the water into other
containers.
2:Turn on the machine, adjust it to low-wind ventilation mode, and maintain this state until
recovery
cylinders
are
employed.
Ensure
that
the
correct
number
of
cylinders
for
holding
the
total
system
charge
is
available.
All
cylinders
to
be
used
are
designated
for
the
recovered
refrigerant
and
labelled
for
that
refrigerant
(i.e.
special
cylinders
for
the
recovery
of
refrigerant).
Cylinders
shall
be
complete
with
pressure
relief
valve
and
associated
shut-off
valves
in
good
working
order.
Empty
recovery
cylinders
are
evacuated
and,
if
possible,
cooled
before
recovery
occurs.
The
recovery
equipment
shall
be
in
good
working
order
with
a
set
of
instructions
concerning
the
equipment
that
is
at
hand
and
shall
be
suitable
for
the
recovery
of
flammable
refrigerants.
In
addition,
a
set
of
calibrated
weighing
scales
shall
be
available
and
in
good
working
order.
Hoses
shall
be
complete
with
leak-free
disconnect
couplings
and
in
good
condition.
Before
using
the
recovery
machine,
check
that
it
is
in
satisfactory
working
order,
has
been
properly
maintained
and
that
any
associated
electrical
components
are
sealed
to
prevent
ignition
in
the
event
of
a
refrigerant
release.
Consult
manufacturer
if
in
doubt.
The
recovered
refrigerant
shall
be
returned
to
the
refrigerant
supplier
in
the
correct
recovery
cylinder,
and
the
relevant
Waste
Transfer
Note
arranged.
Do
not
mix
refrigerants
in
recovery
units
and
especially
not
in
cylinders.
If
compressors
or
compressor
oils
are
to
be
removed,
ensure
that
they
have
been
evacuated
to
an
acceptable
level
to
make
certain
that
flammable
refrigerant
does
not
remain
within
the
lubricant.
The
evacuation
process
shall
be
carried
out
prior
to
returning
the
compressor
to
the
suppliers.
Only
electric
heating
to
the
compressor
body
shall
be
employed
to
accelerate
this
process.
When
oil
is
drained
from
a
system,
it
shall
be
carried
out
safely.
