technicians are required to have been trained on the following
topics when installing and servicing air-conditioning equipment
with A2L refrigerant such as R-32:
•
Explosive potential of A2L refrigerants
•
Potential ignition sources
•
Safety measures for unventilated and ventilated rooms or
enclosures
•
Refrigerant detectors
•
Concept of sealed components and sealed enclosures ac-
cording to IEC 60079-15:2010
•
Correct work procedures for the following:
- Commissioning
- Maintenance
- Repair
- Decommissioning
- Disposal
When installing this accessory, observe precautions in the
