are designated for the recovered refrigerant and labelled for that refrigerant (i.e. 
special cylinders for the recovery of refrigerant). Cylinders shall be complete with 
pressure relief valve and associated shut-off valves in good working order. Empty 
recovery cylinders are evacuated and, if possible, cooled before recovery occurs.     
The recovery equipment shall be in good working order with a set of instructions   
concerning the equipment that is at hand and shall be suitable for the recovery of   
flammable refrigerants. In addition, a set of calibrated weighing scales shall be 
available and in good working order. Hoses shall be complete with leak-free 
disconnect couplings and in good condition. Before using the recovery machine, 
check that it is in satisfactory working order, has been properly maintained and that 
any associated electrical components are sealed to prevent ignition in the event of 
a refrigerant release. Consult manufacturer if in doubt.   
The recovered refrigerant shall be returned to the refrigerant supplier in the correct   
recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix   
refrigerants in recovery units and especially not in cylinders.  
If compressors or compressor oils are to be removed, ensure that they have been   
evacuated to an acceptable level to make certain that flammable refrigerant does 
not remain within the lubricant. The evacuation process shall be carried out prior to 
returning the compressor to the suppliers. Only electric heating to the compressor 
body shall be employed to accelerate this process. When oil is drained from a 
system, it shall be carried out safely.
