gerant.The label shall be dated and sgned.
Ensure that there are labels on the equpment
statng the equpment contans flammable
refrgerant.
2.11 Recovery
When removng refrgerant from a system,
ether for servcng or decommssonng, t s
recommended good practce that all refrgerants
are removed safely. When transferrng refrgerant
nto cylnders, ensure that only approprate
refrgerant recovery cylnders are employed.
Ensure that the correct number of cylnders for
holdng the total system charge are avalable.
All cylnders to be used are desgnated for the
recovered refrgerant and labelled for that
refrgerant (.e. specal cylnders for the recovery
of refrgerant). Cylnders shall be complete wth
pressure relef valve and assocated shut-off
valves n good workng order. Empty recovery
cylnders are evacuated and, f possble, cooled
before recovery occurs.
The recovery equpment shall be n good workng
order wth a set of nstructons concernng the
equpment that s at hand and shall be sutable
for the recovery of flammable refrgerants.In
addton,a set of calbrated weghng scales shall
be avalable and n good workng order. Hoses
shall be complete wth leak-free dsconnect
couplngs and n good condton. Before usng the
recovery machne, check that t s n satsfactory
workng order, has been properly mantaned
and that any assocated electrcal components
are sealed to prevent gnton n the event of a
refrgerant release. Consult manufacturer f n
doubt.
The recovered refrgerant shall be returned to
the refrgerant suppler n the correct recovery
cylnder, and the relevant Waste Transfer Note
arranged. Do not mx refrgerants n recovery
unts and especally not n cylnders.
If compressors or compressor ols are to be
removed, ensure that they have been evacuated
to an acceptable level to make certan that
flammable refrgerant does not reman wthn the
lubrcant. The evacuaton process shall be carred
out pror to returnng the compressor to the
supplers. Only electrc heatng to the compressor
body shall be employed to accelerate ths process.
When ol s draned from a system, t shall be

to teach the relevant natonal competency
standards that may be set n legslaton.
The acheved competence should be documented
by a certfcate.
Tranng
The tranng should nclude the substance of the
followng:
Informaton about the exploson potental of
flammable refrgerants to show that flammables
may be dangerous when handled wthout care.
Informaton about potental gnton sources,
especally those that are not obvous, such as
lghters, lght swtches, vacuum cleaners, electrc
