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.
The unit contains fluorinated greenhouse gases. The refrigerant must not be released into the air!
All products comply with the following EU regulations:
Low Voltage Directive, Electromagnetic Compatibility.
