weighing scales should be available and in good working order.
Hoses should 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 should 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 should be carried out prior to returning the
compressor to the suppliers.
Only electric heating to the compressor body should be employed to
accelerate this process. When oil is drained from a system, it should be
carried out safely.
12. Transportation, marking and storage for units
1. Transport of equipment containing flammable refrigerants
Compliance with the transport regulations
2. Marking of equipment using signs
Compliance with local regulations
3. Disposal of equipment using flammable refrigerants
Compliance with national regulations
4. Storage of equipment/appliances
The storage of equipment should be in accordance with the
manufacturer's instructions.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that
mechanical damage to the equipment inside the package will not
cause a leak of the refrigerant charge. The maximum number of
pieces of equipment permitted to be stored together will be
determined by local regulations.
