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.
