•  Charging procedures
   In 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.
  Label 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. The 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.
  a)  Become familiar with the equipment and its operation.
  b) Isolate system electrically.
  c)   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; The recovery process is 
supervised at all times by a competent person; Recovery equipment and 
cylinders conform to the appropriate standards.
  d) Pump down refrigerant system, if possible.
  e)   If a vacuum is not possible, make a manifold so that refrigerant can be removed 
from various parts of  the system.
  f)  Make sure that cylinder is situated on the scales before recovery takes place.
  g)  Start the recovery machine and operate in accordance with manufacturer’s 
instructions.
  h) Do not overfill cylinders. (No more than 80 % volume liquid charge).
  i)  Do not exceed the maximum working pressure of thecylinder, even temporarily.
  j)   When the cylinders have been filled correctly and the process completed, make 
sure that the cylinders and the equipment are removed from site promptly and 
all isolation valves on the equipment are closed off.
  k)   Recovered refrigerant shall not be charged into another refrigeration system 
unless it has been cleaned and checked.
• Labelling
   Equipment shall be labelled stating that it has been de-commissioned and emptied 
of refrigerant. The label shall be dated and signed. Ensure that there are labels on 
the equipment stating the equipment contains flammable refrigerant.
