Disposal and Recycle
Disposal:
The technician shall be familiar with the device and all its characteristics before disposal. Proceeding safe recycle
of refrigerant is recommended. If the recycled refrigerant shall be utilized, please analyze the sample of refrigerant and
oil before proceeding. Please ensure the required power supply is used before testing. Please take the following
operation
1. Be familiar with the device and its operation.
2. Cut off power supply.
3. It is recommended to use a mechanical recovery device to recover refrigerant prior to the recycling/disposal of the
unit. When recovering refrigerant, all necessary personal protective equipment must be worn to ensure no bodily
harm during this process. All devices should be rated for use on the proper refrigerant, in order to comply with
relevant standards.
4. Please pump the evacuated system into a vacuum. If a full system vacuum cannot be achieved, please attempt to
vacuum from multiple locations internal to the refrigerant piping.
5. Make sure the capacity of refrigerant tank is sufficient before stating the refrigerant recycle process.
6. Start and operate the recycle device according to the operation instruction of manufacturer.
7. The refrigerant tank shall not be too full. The filled liquid shall not exceed 80% of the capacity of refrigerant tank.
8. Do not exceed the maximum operation pressure although the duration is short.
9. Remove the refrigerant tank and device quickly after finishing operation and make sure all cut-off valves in the
device are closed.
10. The recycled refrigerant cannot be filled into another refrigeration system before purification and inspection.
Label
The unit shall be labeled with data and note after scrapping and discharging refrigerant. Make sure the label on the
unit can reflect the R32 refrigerant which it has been filled.
Recycle
I
t’s recommended to remove the refrigerant in the system before maintenance and disposal.
Put the refrigerant into the specialized refrigerant tank with refrigerant label. The refrigerant tank shall be equipped with
pressure relief valve and cut off valve which are in good condition. If possible, the tank should be pulled into a vacuum
before using and keep it at normal temperatures.
Recycling device shall be kept in good working status and equipped with operation instructions for reference. The
device shall be applicable for the recycle of R32 Refrigerant. In addition, qualified weighing apparatus which can be
used normally shall be prepared. The hose shall adopt removable connector without leakage for connection and keep
it in good status. Check if the recycling device is in normal status before using it and if it is properly stored with all
electrical components sealed to prevent fire hazard caused by refrigerant leakage. Call service center if you have any
questions.
The recycled refrigerant shall be put in proper container attached with transportation instruction and sent it back to the
refrigerant manufacturer. Do not mix different refrigerants in the refrigerant recycle device, especially the refrigerant
tank. When disassembling the compressor or clearing the compressor oil, make sure the compressor has pumped into
a proper vacuum, so that there is no R32 refrigerant remained in the lubricant. Vacuum pumping shall be done before
the compressor is sent back to the supplier. Only electric heating can be used to heat the shell of compressor in order
to speed up the course. When oil is drained from the system, please ensure the safety.
Information on servicing
Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimized.
General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the
conditions within the area have been made safe by control of flammable material.
