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 off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and
checked.
10. 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.
11. 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 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.
Fuse parameters of the machine
Type: 5ET or SMT
Voltage: 250V
A. Unit Storage:
1:Unscrew the drainage cover, unplug the water plug, and discharge the water in the water pan into other water
containers or directly tilt the body to discharge the water into other containers.
2:Turn on the machine, adjust it to low-wind ventilation mode, and maintain this state until the drainage pipe
becomes dry, so as to keep the inside of the body in a dry state and prevent it from mildewing.
3:Turn off the machine, unplug the power plug, and wrap the power cord around the wrapping post; install the water
plug and the drainage cover.
4:Remove the exhaust pipe and keep it properly.
5:Cover the air conditioning with a plastic bag. Put the air conditioning in a dry place, keep it out of the reach of
children, and take dust control measures.
6:Remove batteries of the remote control and keep them properly.
Note: ensure that the body is placed in a dry place and keep all machine components properly.
