pressurized refrigerant systems:
• For example, a refrigeration technician, refrigeration mechatronic
engineer. As well as professions with comparable training, which

1.3 Danger to life and limb in the event of faults during operation
WARNING If a compressor continues to be operated during extreme running
noise and/or a sharp reduction in refrigerating capacity, there is
the danger of further events occurring, such as the fracture of the
housing wall. If people are standing in the immediate surroundings,
there is the risk of severe injury or even death from flying parts.
• In the event of extreme running noise, switch the compressor off
immediately.
• If there is a sharp reduction in refrigerating capacity, switch the
compressor off immediately.
• Secure the compressor against being switched on again.
• In such cases do not continue to operate the compressor under any
circumstances.
