11.10 SOUND GENERATION IN REFRIGERATION SYSTEM
Noise and vibrations coming from system or service may come from these sources:
• sound radiation – extend by air
• mechanical vibrations – extended along the parts of the unit and
structure
• gas pulsation – distributed by cooling medium (refrigerant)

before deciding to proceed with it.
Improper procedures to remove the failed compressor and install a new one, may
cause injury to person, release of refrigerants and oil to the environment, fire and
damages to propriety.
When repairing a refrigeration system, replacing a compressor and installing a new
ones, follow all applicable international regulation and standards (like EN 378-4 or
similar), and the local ones, as well as the safety warnings and recommendations
indicated in these installation instructions.
The compressor replacement must be carried out in properly ventilated ambient.
