g)Start the recovery machine and operate in accordance with instructions.
h)Do not overfill cylinders (no more than 80 % volume liquid charge)
i) Do not exceed the maximum working pressure of the cylinder, 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 o.
k)Recovered refrigerant shall not be charged into another refrigerating system
unless it has been cleaned and checked.
Equipment shall be labelled stating that it has been de-commissioned and emptied
of refrigerant. The label shall be dated and signed. For appliances containing
flammable refrigerants, ensure that there are labels on the equipment stating the
equipment contains flammable refrigerant.
17. Labelling
18. Recovery
When removing refrigerant from a system, either for servicing or decommissioning,
it is required to follow good practice so that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant
recovery cylinders are employed. Ensure that the correct number of cylinders for
holding the total system charge is available. All cylinders to be used 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-o 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
the flammable refrigerant. Consult manufacturer if in doubt. 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.
The recovered refrigerant shall be processed according to local legislation 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 compressor body shall not be heated by an
open flame or other ignition sources to accelerate this process. Draining of oil from
a system shall be carried out safely.
19. Venting of HC Refrigerant (R290)
Venting to inside a building is not permissible under any circumstances
Venting must not be to a public area, or where people are unaware of the procedure
taking place.
Venting may be carried out as an alternative to recovering the refrigerant. Because
HC refrigerants have no ODP and negligible GWP, under certain circumstances it may
be considered acceptable to vent the refrigerant. However, if this is to be considered,
it should be done in accordance with the relevant national rules or regulations, if they
permit.
In particular, before venting a system, it would be necessary to:
Ensure that legislation relating to waste material has been considered
Ensure that environmental legislation has been considered
Ensure that legislation addressing safety of hazardous substances is satisfied
Venting is only carried out with systems that contain a small quantity of refrigerant,
typically less than 500g.
