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: 5H, 5TE, 932, 5N, 524 or 50CT Voltage: 250V Current: 3.15 A
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.
