Dehumidifier 50, 35, 22 Pint · Important Safety Instructions · 11
j. When the cylinders have been lled correctly and the process is completed, make
sure that the cylinders and the equipment are removed from the site promptly and all
isolation valves on the equipment are closed off.
k. Recovered refrigerant shall not be charged into another refrigeration system unless it
has been cleaned and checked.
14. Labeling
The unit shall be labeled stating that it has been decommissioned and emptied of the
refrigerant. The label shall be dated and signed. Ensure that there are labels on the unit
stating that it contains ammable refrigerants.
15. Recovery
When removing the refrigerant from a system, either for servicing or decommissioning,
it is recommended that all refrigerants are removed safely.
When transferring the refrigerant into the cylinders, ensure that only appropriate
refrigerant recovery cylinders are used. 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 labeled for that refrigerant (i.e., special cylinders refrigerant
recovery). Cylinders shall be complete with pressure relief valves and associated shut-
off valves in good working order. Empty recovery cylinders should be evacuated and, if
possible, cooled before the 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
ammable 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 if a refrigerant is released. Consult Customer
Service when 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 the compressors or the compressor oils
are to be removed, ensure that they have been evacuated to an acceptable level so that the
ammable 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 the system, it shall be carried out safely.
