Ensure that the outlet for the vacuum pump s
not close to any gnton sources and there s
ventlaton avalable.
2.8 Chargng procedures
In addton to conventonal chargng
procedures,the followng requrements shall be
followed.
– Ensure that contamnaton of dfferent
refrgerants does not occur when usng
chargng equpment. Hoses or lnes shall
be as short as possble to mnmze the
amount of refrgerant contaned n them.
– Cylnders shall be kept uprght.
– Ensure that the refrgeraton system s
earthed pror to chargng the system wth
refrgerant.
– Label the system when chargng s
complete (f not already).
– Extreme care shall be taken not to overfll
the refrgeraton system.
Pror to rechargng the system t shall be
pressure tested wth OFN. The system shall be
leak tested on completon of chargng but pror
to commssonng. A follow up leak test shall be
carred out pror to leavng the ste.
2.9 Decommssonng
Before carryng out ths procedure, t s essental
that the techncan s completely famlar wth the
equpment and all ts detal. It s recommended
good practce that all refrgerants are recovered
safely. Pror to the task beng carred out, an ol
and refrgerant sample shall be taken n case
analyss s requred pror to re-use of reclamed
refrgerant. It s essental that electrcal power s
avalable before the task s commenced.
a) Become famlar wth the equpment and
ts operaton.
b) Isolate system electrcally.
c) Before attemptng the procedure ensure
that: mechancal handlng equpment
s avalable, f requred, for handlng
refrgerant cylnders; all personal
protectve equpment s avalable and
beng used correctly; the recovery process
s supervsed at all tmes by a competent
person; recovery equpment and cylnders
conform to the approprate standards.
d) Pump down refrgerant system f possble.
e) If a vacuum s not possble, make a manfold
so that refrgerant can be removed from
varous parts of the system.
f) Make sure that cylnder s stuated on the
scales before recovery takes place.
g) Start the recovery machne and operate
n accordance wth manufacturer’s
nstructons.
h) Do not overfll cylnders. (No more than 80 %
volume lqud charge).
) Do not exceed the maxmum workng
pressure of the cylnder,even temporarly.
j) When the cylnders have been flled
correctly and the process completed, make
sure that the cylnders and the equpment
are removed from ste promptly and all
solaton valves on the equpment are
closed off.
k) Recovered refrgerant shall not be charged
nto another refrgeraton system unless t
has been cleaned and checked.
