-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 commissioning.
A follow up leak test shall be carried out prior to leaving the site.
16.Decommissioning
Before carrying out this procedure, it is essential that technician is completely
familiar with the equipment and all its detail. It is recommended good practice
