charge is used, and ensuring that the outlet for the vacuum pump is not close to
any potential ignition sources.
Before decommissioning units containing R32 refrigerant, you must make
sure:
PPE is available and being used correctly and that the technician is completely
familiar with the equipment.
The recovery process is being supervised by a competent person.
Electrical power is available before decommissioning and isolate the system
electronically.
Refrigerants can be recovered safely, taking an oil and refrigerant sample in
case analysis is required prior to reuse of recovered refrigerant.
Equipment is available for handling refrigerant cylinders if required. Make sure
that recovery equipment and cylinders conform to the appropriate standards.
Only appropriate cylinders (designated for R32 refrigerant and labeled as such)
are used for recovery, and that the correct number of cylinders for holding the
total charge are available.
Cylinders are evacuated prior to use.
Recovery equipment is working and instructions are available.
Calibrated weighing scales are available, that hoses have leak free disconnect
couplings and are in good condition.
The recovery machine is working properly and any potential ignition sources are
sealed.
There's not potential for mixing refrigerants in cylinders or recovery units.
Compressors or compressor oils are properly evacuated if they are to be
removed, and evacuating the compressor prior to returning the compressor to
the suppliers if it is evacuated.
Oil is drained out safely if it is to be drained out.
Decommissioning Process
Pump down the refrigerant system if possible (otherwise making a manifold so
that refrigerant can be removed from various parts), making sure that the
cylinder is on the scales before recovering refrigerant.
Operate the recovery machine in accordance with instructions, not filling
cylinders to more than 80% liquid volume charge, not exceeding the max
working pressure of the cylinders, and making sure that cylinders are filled
correctly and removed from site after the process is completed.
Do not charge recovered refrigerant into another system until it has been
cleaned and checked.
After completion, label the unit to show when it was decommissioned and
emptied of refrigerant, that the label must be dated and signed, and ensuring
