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: 5TE or 5ET or 5H or 5N 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.
