ENGLISH
- The flammable refrigerant must be returned to the refrigerant supplier in the correct
recovery cylinder, and the applicable waste transfer note must be provided. Do not mix
refrigerants in recovery units and especially not in cylinders.
- If compressors and compressor oils are to be removed, ensure that they have been
drained to an acceptable level so that no flammable refrigerant remains within the
lubricant. The evacuation process must be carried out before returning the compressor
to the suppliers. Only electrical heating of the compressor body should be used to
accelerate this process. When oil is drained from a system, it must be done in a safe
manner.
Competence of service staff
General
- Special training in addition to normal refrigeration equipment repair procedures is
required when the equipment is affected by flammable refrigerants.
In many countries, this training is carried out by national training organisations that are
accredited to teach the relevant national competence standards that may be laid down in
legislation.
- The competence obtained must be documented by a certificate.
Training
The training should include the following:
- Information on the explosion potential of flammable refrigerants to demonstrate that
flammable materials can be hazardous if handled carelessly.
- Information on possible ignition sources, especially those that are not obvious, such as
lighters, light switches, vacuum cleaners, or electric heaters.
- Information on the different security concepts:
- Unventilated - (see Clause GG.2). The safety of the device does not depend on the
ventilation of the housing. Switching off the device or opening the housing has no
significant effect on safety. However, it is possible that refrigerant leaks may accumulate
inside the appliance and a flammable atmosphere may be released when the housing is
opened.
- Ventilated enclosure - (see Clause GG.4) The safety of the appliance depends on the
ventilation of the enclosure. Switching off the device or opening the housing has a
considerable effect on safety. Make sure there is enough ventilation before using the
appliance.
- Ventilated room - (see Clause GG.5) The safety of the appliance depends on the
ventilation of the room. Switching off the device or opening the housing has no
significant effect on safety. Ventilation of the room must not be interrupted during repair
procedures. Information on the concept of sealed components and sealed enclosures
according to IEC60079-15: 2010.
- Information on correct working procedures:
