SAFETY INSTRUCTIONS
on the equipment are closed off.
k. Recovered refrigerant shall not be charged into another refrigerating system unless it
has been cleaned and checked.
14. Labelling
Equipment shall be labelled stating that it has been de-commissioned and emptied
of refrigerant. The label shall be dated and signed. Ensure that there are labels on the
equipment stating the equipment contains flammable refrigerant.
15. Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is
recommended good practice 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 shutoff 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. When moving or relocating the air conditioner, consult
experienced service technicians for disconnection and reinstallation of the unit. Do not
place any other electrical products or household belongings under indoor unit or outdoor
unit. Condensation dripping from the unit might get them wet, and may cause damage
or malfunction of your property. To keep ventilation openings clear of obstruction. The
appliance shall be stored in a well-ventilated area where the room size corresponds
to the room area as specified for operation. The appliance shall be stored in a room without
continuously operating open flames (for example an operating gas appliance) and ignition
sources (for example an operating electric heater). Reusable mechanical connectors and
flared joints are not allowed.
