16.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, en-
sure 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 refr-
igerant). 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 com-

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 refrig-
erant does not remain within the lubricant. The evacuation process shall be carried out prior to ret-
urning the compressor to the suppliers. Only electric heating to the compressor body shall be empl-
oyed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

supply cord as follows:
1. Plug in the air conditioner.
2. The power supply cord will have TWO buttons on the
plug head. Press the TEST button. You will notice a click as
the RESET button pops out.
