vacuum pump is not close to any ignition sources and there is
ventilation available.
Charging Procedures. I
n addition to conventional charging
procedures, the following requirements shall be followed.
Ensure
that contamination of different refrigerants does not occur when
using
charging equipment. Hoses or lines shall be as short as
possible to minimise the amount of refrigerant contained in them.
Cylinders shall be kept upright. Ensure that the refrigeration
system is earthed prior to charging the system with refrigerant.
L
abel
the
system
when
charging
is
complete
(if
not
already).
Extreme
care shall be taken not to overfill the refrigeration system. Prior to
recharging the system it shall be pressure tested with
ofn. T
he
system
shall
be
leak
tested
on
completion
of
charging
but
prior
to
commissioning. a follow up leak test shall be carried out prior to
leaving the site.
Decommissioning.
Before carrying out this procedure, it is
essential that the technician is completely familiar with the
equipment and all its detail. it is recommended good practice that
all refrigerants are recovered safely. Prior to the task being carried
out, an oil and refrigerant sample shall be taken in case analysis is
required prior to re-use of reclaimed refrigerant. it is essential that
electrical power is available before the task is commenced.
-
Become familiar with the equipment and its operation. Isolate
system electrically. Before attempting the procedure ensure that:
-Mechanical handling equipment is available, if required, for
handling refrigerant cylinders;
All personal protective equipment is available and being used
correctly.
